Extreme dizzinessvertigo

Although patients with cervicogenic disorders can sometimes present with associated dizziness, extreme dizziness, especially if associated with other neurological symptoms, can indicate pathology of the central nervous system, and treatment is contraindicated. Dizziness can also be associated with other pathologies. For dizziness to be deemed cervicogenic in origin, the onset and duration must parallel the neck pain and must be associated with neck movements. If with further questioning any of the symptoms listed in Table 8.4 are reported, pathology of the central nervous system should be suspected, further treatment is contraindicated and the patient should be referred to the appropriate specialist. See next section for fuller discussion about dizziness. constant dizziness vertigo feeling of being pushed to one side facial asymmetry dysarthria dysphagia

Blackouts Syncope and Lightheadedness Near Syncope

Syncope can also be caused by other heart problems. For example, if your heart beats in an abnormal rhythm called an arrhythmia, your heart rhythm may become very slow, or even miss a few beats or several beats in a row. This causes lightheadedness or even unconsciousness that passes after the heart begins beating again. You may also develop syncope as a result of very fast heart rhythms so fast, in fact in the range of 180 to 250 beats per minute that the heart is no longer able to effectively pump blood. In this case, not enough blood gets to the brain.

Benign Paroxysmal Positional Vertigo

The most common cause of peripheral vestibular vertigo in adults is benign paroxysmal positional vertigo. BPPV occurs in all age groups but more often between ages 50 and 70. The incidence of BPPV is 11 to 64 per 100,000 persons per year and is twice as common in women as men (Froehling et al., 1991). It is caused when otoconia particles from the utricle or saccule lodge in the posterior semicircular canal and is also referred to as canalithiasis. This causes the canal to be a gravity-sensing organ, and head movement results in displacement of the otoconia and a sensation of vertigo. The Dix-Hallpike maneuver reproduces this vertigo in the patient, resulting in nystagmus (see eFig. 19-3). Characteristics of the nystagmus of BPPV include fatigability, a latency period of 1 to 5 seconds before nystagmus begins after the head is moved, short duration of nystagmus from 5 to 30 seconds, and reversal of the nystagmus components when the patient is returned to the sitting position. If these...

Benign Positional Vertigo

Benign positional vertigo is believed to be caused by a dislodged otolith from the semicircular canal. Symptoms include episodic vertigo without aural symptoms. Nausea and vomiting may also be present secondary to the vertigo. Common histories include vertigo precipitated by rolling over in bed or bending over to tie shoes. The diagnosis can usually be made by the history and eliciting a positive Dix-Hallpike maneuver. Patients can be expected to have gradual resolution of their symptoms over 4 to 6 weeks with supportive therapy. The canalith repositioning (Epley) maneuver provides short-term resolution of the vertiginous symptoms (Cochrane review Pinder, 2004).

Labyrinthitis Vestibular Abnormalities and Menieres Disease

A comprehensive review of these topics is beyond the scope of this chapter but should be considered when evaluating any patient with dizziness. Patients with the abrupt onset of a single episode of vertigo that gradually resolves over several days often have labyrinthitis or vestibular neuronitis, usually distinguished clinically by the presence or absence of hearing changes. Patients with labyrinthitis usually experience hearing changes, whereas those with vestibular neuronitis do not. A viral infection is the usual cause in younger patients while infarction becomes more likely in the older adult. Older-adult patients may recover more slowly and experience feelings of imbalance for several months. Treatment during the symptomatic period may include vestibular rehab exercises and pharmacologic agents such as meclizine, promethazine, or low-dose benzodiazepine (e.g., lorazepam). Meniere's disease should be suspected when an older adult reports recurrent episodes of vertigo, tinnitus,...

Dizziness of Cervical Origin

Cervical spine problems, especially osteoarthritic changes, can cause dizziness that may be vertiginous in nature and of vascular or proprioceptive origin. In cases of vascular origin, flow through one of the vertebral arteries is temporarily disrupted by an osteoarthritic spur that compresses the vessel when the patient turns the head or looks up. In cases of proprioceptive origin, overstimulation of the proprioceptive receptors in the facet joints produces the sensation of dizziness. Either of these conditions can cause a drop attack. These patients should avoid the position that precipitates the symptoms and, in some cases, cervical collars or cervical traction may be helpful.

Pitfalls in the Diagnosis of Migraine Associated Dizziness

The Neuhauser criteria are sufficiently limited as to make it difficult to definitely pinpoint a syndrome. It is possible to have a person with a history of migraine, now with vertigo and phonophobia but no headache, and meet criteria for MAD. The issue becomes whether one can fully rule out other central or peripheral vestibular disorders causing vertiginous symptoms that are not related to migraine. Vertigo and phonophobia together can co-exist in an otogenic (inner ear) disorder even with normal audiometric and vestibular testing, particularly in early cases of Meniere's disease. Furthermore, the lifetime history of migraine does not preclude a non-migraine etiology of dizziness. To address these diagnostic problems, some authors use the terms migrainous vertigo and migraine-associated vertigo differently, in which the former refers to episodic vertigo spells that occur concurrently with other migraine features and the latter refers to episodic vertigo in an individual with a...

Cervicogenic Dizziness

A controversial disorder referred to as cervicogenic dizziness may overlap with cervicogenic headache. Symptoms include a vague non-vertiginous dizziness, often worse with activity, and may or may not be associated with neck pain or with obvious vestibular pathology. The term cervicogenic dizziness is actually a misnomer in that the neck is not the genesis of the vestibular symptoms, although it plays a vital role. A more descriptive name for this disorder would be cervically mediated dizziness. This disorder may also occur without headache. Formal vestibular testing may be normal or non-specifically abnormal.

Migraine Dizziness and Orthostatic Intolerance OI

Orthostatic intolerance (OI) covers a spectrum of symptoms including presyncope and syncope, weakness and fatigue, tachycardia or palpitations, nausea, and difficulty concentrating. Symptoms can be aggravated by prolonged standing, physical exertion, environmental warming, post-prandial states, and menses. Diagnosis is based on history and results of heads-up tilt table testing. Postural orthostatic tachycardia syndrome is thought to be associated with abnormal venous pooling and fluid collection in the lower extremities. Symptoms that often accompany POTS are tachycardia, hypotension, dizziness, fatigue, palpitations, and nausea. A case series by Stillman in 2003 reviewed patients with headache (all meeting IHS criteria for migraine) and symptoms of presyncope or frank syncope, and revealed significant abnormalities frequently occurred on head-up tilt table testing.

Benign Paroxysmal Vertigo of Childhood BPVC

Benign Paroxysmal Vertigo of Childhood (BPVC) was first described by Basser in 1964. It is characterized by abrupt loss of balance, vertigo, and even falls. The pediatric prevalence is 2-2.6 with equal distribution between boys and girls. Table 7.2 ICHD-2 diagnostic criteria for benign paroxysmal vertigo of childhood At the beginning of the episode, children may appear frightened, while trying to hold on to furniture or another person to avoid falling they refuse to walk and want to lie still. Older children may describe dizziness and nausea. Associated symptoms include nystagmus, pallor, nausea, diaphoresis, phonophobia, and photophobia. Severe vomiting may also occur. There is no loss of consciousness. BPVC is a diagnosis of exclusion differential diagnosis includes posterior fossa pathology and episodic ataxia among others. It must also be differentiated from migraine-associated vertigo, which occurs in older children. Later in life, children may develop cyclical vomiting syndrome...

Vasovagal Fainting and Dizziness

Dizziness is different from lighthead-edness in that a person feels uncomfortable, as if the room is spinning, but usually does not feel as if he or she is about to pass out. A good example is the feeling that occurs after getting off a ride such as a roller coaster at an amusement park. Dizzy spells can also be caused by ear disorders or other problems. In many cases, people misinterpret their dizziness as a

Treatment of Cervically Mediated Dizziness

Cervicogenic dizziness can be successfully treated with a combination of neck physiotherapy, occipital nerve blocks, and oral antineuritic pain medications such as gabapentin or amitriptyline. Thus, nonsurgical treatment for both cervicogenic headache and dizziness overlap. Further understanding of cervicogenic dizziness comes from treating dizzy patients without headache and cervicogenic headache patients without dizziness. The disorder is suggested by not meeting IHS criteria for either cervicogenic headache or migraine. A spectrum of improvement was seen with greater occipital nerve injections for patients with dizziness and headache, including relief of symptoms of ear discomfort, tinnitus, and neck pain, along with improvements in the headache and dizziness. The upper cervical spine may play an important role in various headache and vestibular disorders, and an underlying mechanism may connect the trigeminal nucleus caudalis and trigeminocervical pathways. Due to the intricate...

Diagnosis and Treatment of Dizziness and Headache

Abstract Dizziness and headache are separately quite common. There are, however, a number of scenarios where the two can be interconnected. An area of significant clinical interest at this time is migraine-associated dizziness, in which the migraine generator produces vestibular symptoms. Also, there can be an overlap between orthostatic intolerance and migraine, with a spectrum of symptoms from palpitations and tachycardia to presyncope or actual syncope. A third important area of overlap is related to mechanical syndromes of the neck, cervicogenic headache, which may overlap, occurring with vestibular symptoms. There are also a number of systemic entities that can cause both dizziness and headache covered in this chapter. Keywords Vertigo Dizziness Migraine-associated dizziness Migrainous vertigo Orthostatic intolerance Cervicogenic dizziness Cervically mediated dizziness

Migraine Associated Dizziness MAD

The concept of migraine-associated dizziness has been around for many years but has been recognized more frequently in the past few years. There are a variety of similar terms used for MAD including migrainous vertigo, migraine-associated vertigo, migraine-associated dizziness, and vestibular migraine. Migraine-associated dizziness can occur ictally or interictally with typical migraine episodes. The diagnosis is not recognized by the International Headache Society. Table 20.3 Neuhauser criteria for migrainous vertigo Recurrent vestibular symptoms (rotatory positional vertigo, other illusory self or object motion, head motion intolerance) In 2001, Neuhauser set forth criteria for migrainous vertigo. Requirements included an established history of migraine headaches (see Table 20.3). Furman developed subsequent criteria discussing definite vs. probable migrainous vertigo, with inclusion of vertiginous symptoms triggered by typical migraine precipitants.

Conclusions on Diagnosis and Treatment of Dizziness and Headache

Dizziness and headache are separately quite common. There are, however, a number of scenarios where the two can be interconnected. An area of significant clinical interest at this time is migraine-associated dizziness in which the migraine generator produces the vestibular symptoms. Table 20.10 Factors linking headache and dizziness Migraine-associated dizziness should only be diagnosed in an individual with an established history of migraine. There can be an overlap between orthostatic intolerance and migraine, with a spectrum of symptoms from palpitations and tachycardia to presyncope to actual syncope. Treatment of cervicogenic headache with subsequent resolution of the vestibular symptoms may suggest cervically mediated dizziness. There are also a number of systemic entities that can cause both dizziness and headache (see Table 20.10).

Vertigo Tinnitus

Vertigo and tinnitus can originate from the upper cervical region (CI, C2 dysfunction) or from an obstruction of the vertebral arteries (secondary to a dens defect or cervical osteophytes). It develops from prolonged cervical back bending (i.e., painting a ceiling), a postural forward head carriage, repeated cervical rotation, or rising from a supine to a sitting position or vice versa. This sensation can also be referred from inner ear (vestibular apparatus in semicircular canals) or temporomandibular joint problems.

Acoustic Neuroma

An acoustic neuroma (or more precisely, vestibular schwannoma) is a benign tumor that arises from the Schwann cells of cranial nerve VIII. Acoustic neuromas account for about 10 of all intracranial tumors. They are most commonly diagnosed in middle age. They are slightly more common in women than men. They are usually sporadic but may be associated with neurofibromatosis 1 or 2 (NF-1, NF-2). Most patients with NF-2 will develop bilateral acoustic neuromas. Acoustic neuromas in NF-1 are much less common. The primary symptoms of vestibular schwannoma are asymmetric hearing loss (sensorineural) and tinnitus. The hearing loss is usually gradual in onset and progressive but can occur suddenly. Disequilibrium is not usually the chief complaint on presentation, but patients often admit to mild unsteadiness. Larger tumors can cause dysesthesia around the ear or facial weakness, or both. If the neuroma is diagnosed late, patients can manifest cerebellar symptoms and symptoms of mass effect and...


Dizziness is a term used frequently by patients and should be avoided by the interviewer. Dizziness may be the patient's description of vertigo, ataxia, or lightheadedness. Any time the patient uses this term, it must be clarified by additional questioning, because different pathophysiologic mechanisms may be responsible. The interviewer needs to differentiate vertigo from ataxia. If the patient complains of dizziness, it is important to ask these questions ''Would you describe the dizziness as a strange spinning sensation in your head '' ''Did the room spin, or did it feel as if you were spinning '' ''Were you unsteady while walking '' Vertigo is partially discussed in Chapter 11, The Ear and Nose. Vertigo is the hallucination of movement. Acute vertigo may be associated with nausea, vomiting, perspiration, and a sense of anxiety. Ask patients whether they have the sensation that objects are moving around them or that they are spinning or moving. In addition to the questions in...

Postural Dizziness

Nonvertiginous postural dizziness suggests postural hypotension. Orthostatic hypotension is usually defined as a 20 mm Hg drop in systolic BP or 10 mm Hg drop in diastolic BP 2 minutes after moving from a recumbent to standing position. Older-adult patients, however, can develop postural dizziness without apparent postural hypotension. In some cases, no BP decline occurs, although enough blood pools in the older adult's lower extremities to impair cerebral perfusion. When postural dizziness without postural hypotension is suspected, an evaluation of the cardiovascular system should be considered. If significant cardiovascular pathology, such as congestive heart failure, is not identified, a therapeutic trial of support stockings and optimized hydration can be contemplated.

Nausea and Dizziness

Table 20.2 Clinical pearls on duration of dizziness Benign paroxysmal positional vertigo (BPPV) Migraine-associated dizziness (MAD) o Seconds to hours to days There is, however, much evidence to suggest that motion sickness may also have its roots in migraine. Furman and Marcus demonstrated that migrainous vertigo responded to rizatriptan. Therefore, factors that aggravate migraine may also increase sensitivity to motion, and associated dizziness in susceptible individuals.


As with vestibular neuronitis, labyrinthitis causes sudden and severe vertigo. In contrast to vestibular neuronitis, the patient also has tinnitus and hearing loss. The hearing loss is sensorineural, is often severe, and can be permanent. Laby-rinthitis is caused by inflammation within the inner ear. The cause is most often a viral infection but can be bacterial. Bacterial labyrinthitis usually results from extension of a bacterial otitis media into the inner ear. A noninfectious serous labyrinthitis can also occur after an episode of acute otitis media. Other, less common causes include treponemal infections (syphilis) and rickettsial infection (Lyme disease). Symptomatic treatment of labyrinthitis is similar to that for vestibular neuronitis. Antibiotics are recommended if a bacterial cause is suspected. As with acute otitis media, bacterial labyrinthitis can, in rare cases, lead to meningitis. Few other conditions cause the constellation of hearing loss, tinnitus, and vertigo, but...

Vestibular Examination

The vestibular system is highly integrated with the visual, pro-pioceptive, cerebellar, and motor systems. Dysfunction of any one of these systems may result in dizziness or imbalance. The vestibular examination consists of two principal components observation of eye movements to evaluate the vestibulocular reflex and examination of balance and coordination to evaluate the vestibulospinal, cerebellar, and proprioception function.

The First Spinal Anesthetic

Approximately 10 minutes after the second injection, the man's legs began to feel sleepy. After another 15 to 20 minutes, the intensity of the anesthesia had increased, and although there were some evidences of the diffusion part of the anesthetic, the impairment of sensibility was principally limited to the lower extremities, the lumbar regions, the penis, and scrotum. While standing with eyes closed, the man experienced some dizziness, but no incoordination or motor impairment was discernible in his gait. He left the office 1 hour or more after the last injection and seemed none the worse for the experience.11

The Long List of Inventions and Observations that Led to the Pacemaker

Shortly thereafter, Irish physicians Robert Adams and William Stokes described in separate publications patients who had low pulses and syncope. They also noted that bradycardia leads to dizziness, short pauses to more dizziness, and longer pauses to visual aura, then to complete syncope, convulsions, and finally death. In other words, longer pauses led to more symptoms. Although, Morgagni and Mercuariale had already made less detailed observations, Stokes and Adams are generally credited with the observation that syncope could have bradycardic instead of neurologic origin.6

Diagnosis Using the ICHD2

A few clinical pearls help with using the ICHD-2 criteria. Although migraine is often suggested by the company it keeps (menses, stress, red wine, or weather triggers, history of motion sickness, family history), triggers are not included in the strict criteria for diagnosis. 6. Many migraine patients have either a family history of headaches, personal histories of motion sickness, especially in childhood, or both and aura can both be absent. Many migraine patients have either a family history of headaches, personal histories of motion sickness, especially in childhood, or both.

Dichotomous Classification

According to Jean Piaget, intrinsic motivation is preceded by certain cognitive operations. This occurs when individuals encounter new knowledge that they cannot make sense of. In this case, new ideas are not compatible with current conceptions, and disequilibrium emerges and continues until the individual assimilates or accommodates to reach equilibrium again. At that point, it is critical to point out that creativity is achieved as long as individuals can adapt to new information and expose themselves to perennial conflicts, even as they grow older. Morris I. Stein also acknowledged the role of disequilibrium, claiming that it takes place at the beginning of the creative process.

Pharmacologic Therapies

The newer agents have less adverse side effects and should be used in older men who have low blood pressure or episodes of dizziness. The addition of an antimus-carinic drug can be considered in those men who are still symptomatic on alpha-antagonist therapy. For long-term treatment of overflow incontinence in men, 5a-reductase inhibitors alone or in combination have been shown to reduce the voiding symptoms from BPH as well as the incidence of urinary retention (McConnell et al., 2003).

Anxiety and Obsessive Compulsive Disorder Syndromes

Anxiety is an extremely common occurrence that affects everyone at some time and is characterized by an unpleasant and unjustified sense of fear that is usually associated with autonomic symptoms including hypervigilance, palpitations, sweating, lightheadedness, hyperventilation, diarrhea, and urinary frequency as well as fatigue and insomnia. Anxiety is thought to be mediated through the limbic system, particularly the cingulate gyrus and the septal-hippocampal pathway, as well as the frontal and temporal cortex. The term anxiety disorder is used to denote significant distress and dysfunction resulting from anxiety, including panic attacks and anxiety with specific phobias. Chronic, moderately severe anxiety tends to run in families and may be associated with other anxiety disorders or depression. The differential diagnosis of anxiety states includes other psychiatric conditions such as anxious depression as well as schizophrenia, which may present as a panic attack with disordered...

Cerebellar Infarct and Vertebral Artery Neck Occlusion

A 55-year-old Caucasian man suddenly became dizzy while shoveling snow and could not walk. His wife helped him inside. In the ambulance he vomited and felt discomfort in the back of his left head, neck, and shoulder. He had had hypertension for 10 years, and 5 years ago he had coronary artery bypass surgery. He took aspirin, a statin, and an angiotensin converting enzyme inhibitor. Three days before, he had had a very brief attack of dizziness and blurred vision, and had veered to the left. He had not reported this episode to his doctor.

In clinical trials, ranolazine at a dose of 750 to 1,000 mg twice daily improved angina and increased exercise capacity when added to other antianginal therapy.35,36 Ranolazine has minimal effects on heart rate or blood pressure however, it has the potential to prolong the QT interval and increase the risk for the life-threatening arrhythmia, torsades de pointes. Therefore, ranolazine should be reserved for patients with angina that is refractory to traditional antianginal medications. Contraindications to ranolazine are shown in Table 7-10. Common adverse effects with ranolazine include dizziness, headache, constipation, and nausea. Syncope may occur infrequently. Ranolazine is a substrate for CYP3A4 and both an inhibitor and substrate of p-gly-coprotein. Concomitant use of ranolazine with moderate to potent CYP3A4 inhibitors, including verapamil and diltiazem, is contraindicated. Ranolazine should be used cautiously with p-glycoprotein inhibitors (e.g., cyclosporine) and substrates...

Class 1 antiarrhythmics Class la

Quinidine is an isomer of quinine formerly used in the treatment of atrial and supraventricular tachycardias. It has antimuscarinic and a-blocking properties, the latter causing vasodilatation and decreased myocardial contractility severe hypotension may occur after i.v. administration. It may cause conduction defects or accelerate AV node conduction, accelerating ventricular rate and leading to ventricular arrhythmias. Visual and auditory disturbances with vertigo and gastrointestinal symptoms are signs of toxicity. Idiosyncratic reactions (rashes, thrombocytopenia and agranulocytosis) may also occur. Quinidine enhances digoxin toxicity by increasing plasma concentrations. It has an additive effect with other cardiodepressant drugs (e.g. disopyramide, P-blockers and calcium channel blockers) and potentiates the effects of non-depolarizing neuromuscular blockers.

Symptoms are produced only when the blood supply to an area is significantly compromised (Grant 2002). If present, symptoms reflect brainstem dysfunction - confusion, vertigo, diplopia, dysarthria, bilateral weakness or paraesthesia in the extremities and drop attacks may occur (Berkow et al. 1992).

History of Chiropractic

Palmer argued that his chiropractic approach offered the world an important new philosophy. He believed that God had created a balanced, ordered universe and that equilibrium was the fundamental organizing principle of life. Innate intelligence represented God's presence in human beings. Subluxations created disequilibrium, and the inevitable sequela of this violation of natural law was disease.

The Psychosomatic Patient

There are many ways of dealing with psychosomatic patients. First, identify the disorder Do not miss the possible diagnosis of an affective or anxiety disorder. Treatment of somatization is directed toward teaching the patient to cope with the psychological problems. Be aware that somatization operates unconsciously the patient really is suffering. Above all, the patient should never be told that his or her problem is ''in your head.'' Anxiety, fear, and depression are the main psychological problems associated with psychosomatic illness. The list of associated common symptoms and illnesses is long and includes chest pain, headaches, peptic ulcer disease, ulcerative colitis, irritable bowel syndrome, nausea, vomiting, anorexia nervosa, urticaria, tachycardia, hypertension, asthma, migraine, muscle tension syndromes, obesity, rashes, and dizziness. Answers to an open-ended question such as ''What's been happening in your life '' often provide insight into the problems.

The Symptoms of Pregnancy and Warning Signs of Cardiac Disease

Palpitations are coupled with extreme elevations in heart rate, or with lightheadedness, fainting, or chest pain, should a potentially dangerous heart rhythm be suspected. Outpatient heart rhythm monitoring can rule out an abnormality and reassure both patient and physician. If an abnormality is detected and treatment is considered, there are multiple available and safe therapies. Lightheadedness and fainting are not unusual during pregnancy. Nausea from early hormonal changes may trigger dizziness. Also, the uterine pressure on the veins causes pooling of the blood in the legs. The pregnant woman may not easily adjust to movement because venous return to the heart is limited. If fainting occurs unrelated to body position or after exercise, additional investigation is warranted.

What are the warning signs of prostate cancer

In individuals with widespread metastatic disease, bleeding problems can occur. In addition, patients with prostate cancer may develop anemia. The anemia may be related to extensive tumor in the bone, hormonal therapy, or the length of time you have had the cancer. Because the blood count tends to drop slowly, you may not have any symptoms of anemia. Some individuals with very significant anemia may have weakness, orthostatic hypotension (lowering of the blood pressure when you stand up), dizziness, shortness of breath, and the feeling of being ill and tired. Symptoms of advanced disease and their treatments are listed in Table 4.

Screening of Genes on the Linkage Region of Chromosome 21 Identification of COL6A1

To pinpoint the locus for OPLL on chromosome 21, linkage disequilibrium mapping was performed using gene-based SNPs in the linkage region (Ztr > 2.2) spanning approximately 30 cM. First, 600 SNPs of 150 genes in the linkage region with 96 selected patients and 96 controls were genotyped. Allelic association was carried out, and statistical significance was assessed by x2 analysis with a contingency table. Altogether, 74 SNPs of 24 genes exhibited significant allelic associations (P < 0.05). For the second screening, 74 SNPs in a larger number of OPLL patients (n 280) and non-OPLL controls (n 210) were genotyped. Furthermore, 14 SNPs of seven genes had allelic associations (P < 0.01) with OPLL. The most significant association with OPLL was observed with SNPs of COL6A1, which is located 1.2 Mb from the peak linkage marker D21S1903. Because the four genes (COL18A1, PCBP3, COL6A1, COL6A2) that showed positive associations with OPLL are clustered within a 750-kb region in the...

Clinical Presentation

The postconcussion syndrome represents persistent symptoms following a concussion and may include persistent headache, irritability, inability to concentrate, dizziness, vertigo, memory impairment, generalized fatigue, changes in mood, cognitive deficits, depression, and anxiety. Postconcussion syndrome in the athlete is usually self-limited, lasting approximately 7-10 days. However, athletes may underreport or minimize any neurological or cognitive symptoms in order to return to competition.

Lateral Medullary Infarction

A 43-year-old Chinese man came to the hospital because he could not swallow. Two days before he had suddenly felt a sharp hot stabbing feeling in his right eye and cheek, quickly followed by dizziness and unsteady gait. His voice became hoarse and he choked when he drank tea. He had been an insulin-dependent diabetic for 10 years. He had had several brief episodes of dizziness during the preceding weeks, once accompanied by a feeling that objects were jiggling (oscillopsia). Examination showed blood pressure 135 75, pulse 74 and regular, no cardiac abnormalities and no neck bruits. Neurological findings included decreased pain and temperature sensation on the face bilaterally and the left trunk and limbs right ptosis and meiosis nystagmus on right lateral horizontal gaze hoarse speech and an occasional crowing-like cough decreased motion of the right palate and unsteady gait. Hiccups developed later and were a continued nuisance.

What It Can Do for You

Proponents indicate that fasting may produce fatigue, anemia, irregular heartbeat, body aches, nausea, dizziness, and other negative effects. They refer to these as temporary problems that precede feelings of well-being, mental clarity, internal cleanliness, and other benefits.

Hemicrania Continua HC

The exacerbations of severe headache listed by the ICHD-2 are cluster headachelike with their autonomic features. However, it is clear that exacerbations may mimic migraine, not cluster, in some patients, and the exacerbations may be triptan responsive. Cittadini and Goadsby found photophonophobia in around 75 of their HC patients, ipsilateral in about half. Many had personal or family histories of migraine, often with histories of motion sickness.

The neurological neuropsychological behavioural and emotional consequences of TBI

The most common neurological symptoms following TBI include headache, pain, nausea, dizziness or vertigo, unsteadiness or poor coordination, tinnitus, hearing loss, blurred vision, diplopia, convergence insufficiency, increased light and noise sensitivity, and altered sense of taste and smell. TBI has been noted to cause injury to each of the cranial nerves (Russell, 1960) with the concomitant disruption of the various sensory and motor functions of the head. Waddell and Gronwall (1984), for example, have noted significant increases in the sensitivity to light and sound stimuli following mild TBI.

What Are The Typical Side Effects Of Aeds

Within the first 6 months of treatment with a newly prescribed AED, systemic toxicity and neurotoxicity are as likely to contribute to AED failure as is lack of efficacy. Table 3.2 shows the common neurotoxic effects of AEDs these include diplopia, nystagmus, dysarthria, ataxia, incoordination, tremor, sedation, mood alteration, dizziness, headache, and cognitive impairment. Sufficient time should be allowed during office visits to determine whether a patient is experiencing any side effects. Patients often complain of memory loss. Neuropsychologic testing, as described in Chapter 6, may help determine whether memory loss or trouble concentrating is medication-related.

Evaluation Guidelines

Electrophysiological assessment of the corneal (blink) reflex latency can be reliably measured in an attempt to further localize a supranuclear, nuclear, or peripheral nerve processed This electrically elicited response is similar to that tested at the bedside, and it allows measurement of the response latency after stimulating either the afferent trigeminal or efferent facial nerve components. The facial nerve can be stimulated directly at its exit near the mastoids and the direct response latency (contraction of the ipsilateral orbicularis oculi muscles) measured. For normal adults, this value is typically between 3.0 and 5.0 msec. In contrast, the afferent and efferent limbs of the blink reflex can be tested by stimulating the supraorbital nerve or tapping the glabellar regions and measuring response time to bilateral orbicularis contraction (normal values, approximately 30 msec ipsilateral and contralateral latency differences less than 5 msec). Prolongation of the blink latency...

Patient Encounter 1 Part 1

A 28-year-old healthy woman seeks your advice. She is about to leave on a 7-day Caribbean cruise and is concerned about motion sickness. She recently experienced nausea and one episode of vomiting while on a sailboat on Lake Michigan for an afternoon. She is not allergic to any medications. She does not smoke and only occasionally drinks alcohol. She takes an oral contraceptive (ethinyl estradiol and norges-timate) and occasional ibuprofen for headaches.

Postoperative Nausea and Vomiting

PONV is a common complication of surgery and can lead to delayed discharge and unanticipated hospitalization. The overall incidence of PONV for all surgeries and patient populations is 25 to 30 , but PONV can occur in 70 to 80 of high-risk patients.7,9,11 Risk factors for PONV include patient factors (female gender, nonsmoking status, and history of PONV or motion sickness), anesthetic factors (use of volatile anesthetics, nitrous oxide, or intraoperative or postoperative opioids), and surgical factors (duration and type of surgery). ,9-11

Nausea and Vomiting of Pregnancy

And should be avoided during the first 10 weeks of gestation. , , Motion Sickness and Vestibular Disturbances Nausea and vomiting can be caused by disturbances of the vestibular system in the inner ear.15,55 Vestibular disturbances can result from infection, traumatic injury, neoplasm, and motion. Patients may experience dizziness and vertigo in addition to nausea and vomiting. If a patient is susceptible to motion sickness, some general preventive measures include minimizing exposure to movement, restricting visual activity, ensuring adequate ventilation, reducing the magnitude of movement, and taking part in distracting activities.15 Because the vestibular system is replete with muscarinic type cholinergic and histaminic (Hi receptors, anticholinergics and antihistamines are the most commonly used pharmacologic agents to prevent and treat motion sickness. Oral medications should be taken prior to motion exposure to allow time for adequate absorption. Once nausea and vomiting due to...

General Medical Therapy

Seizures are prevalent in patients with glioma, particularly in slowly growing, low-grade gliomas, and require adequate management. Clinicians should recognize the possibility that seizures could be caused by hyponatremia, hypoglycemia, and hypocalcemia, as well as by mass effect. Seizures are generally managed with standard anticonvulsants, including phenytoin, phenobarbital, primidone, gabapentin, lamotrigine, carba-mazepine, valproic acid, and clonazepam. Anticonvulsants, which are generally dose dependent, can interact with drugs that are commonly given to patients with brain tumors to produce adverse effects, some of which are drowsiness, dizziness, ataxia, nausea, vomiting, confusion, constipation, tremor, hypersalivation, and blurred vision.

Which anticonvulsant is most commonly used for neuropathic pain

Gabapentin (Neurontin) is currently used most often, although its use for pain is off-label. It may be useful for neuropathic extremity pain due to iatrogenic nerve injury, arachnoiditis, prolonged neural compression, and peripheral neuropathy. It has been shown to be useful in some patients with leg pain due to spinal stenosis. Gabapentin is started at 100 to 300 mg at night and then increased to 300 mg every 8 hours over the days to weeks, and then gradually titrated upward until there is good pain relief or significant side effects. Pain relief may occur at 900 mg per day, but often 1800 mg to 3600 mg per day are necessary. Side effects include dizziness, somnolence, ataxia, and headaches, but these are usually seen at the higher dose levels.

History And Definitions

Vertigo is a false sensation of movement that is usually caused by disorders of the vestibular system, including the inner ear and or parts of the central nervous system involved in processing of vestibular signals. Vertigo is often accompanied by imbalance as well as secondary symptoms such as nausea and fatigue. Dizziness is a less specific term often used by patients to indicate vertigo as well as a host of other symptoms such as giddiness or lightheadedness, confusion, and imbalance. The vestibular system senses movement by detecting angular velocity and linear acceleration. The semicircular canals are excellent detectors of angular (rotational) velocity. The otolith organs are detectors of linear acceleration that may be related to either movement of the head or changes in orientation to the earth's gravitational field.

Associated Neurological Findings

Other cranial nerves are rarely involved in processes that affect cranial nerve VIII. Corneal reflexes should be assessed when there are sensory complaints involving the face. Rarely, tumors of cranial nerve VIII grow larger than 3 cm and may compress cranial nerve V. Because cranial nerve VII travels with VIII in the IAC, the examiner should evaluate facial movement. Facial weakness is unusual even with large acoustical neuromas, however. In the brain stem, the nuclei of cranial nerves IX, X, and XI are close to that of VIII, and an assessment of the voice, palatal function, and gag may reveal unilateral weakness in certain patients. A careful oculomotor examination is crucial for detecting many subtypes of central vertigo. Autonomic Nervous System. The pupils should be also checked for Horner's syndrome (miosis, ptosis, and rarely anhydrosis), because the sympathetic system in the brain stem is at times affected with CN VIII dysfunction, particularly with vascular...

Evaluation Guidelines Tables125 and 126

Numerous laboratory procedures are commonly used for evaluation of patients with vertigo and dizziness. For efficiency and cost, procedures should be selected according to specific symptom complexes present in the patient. Neuroimaging. Skull films, cervical spine films, computed tomography (CT) scans of the head, and CT scans of the sinuses are not routinely recommended in the evaluation of vertigo or hearing disturbances. Magnetic resonance imaging (MRI) of the head can be used to evaluate Central vertigo Peripheral vertigo BPPV Vestibular neuritis the structural integrity of the brain stem, cerebellum, periventricular white matter, eighth nerve complexes, and sinuses. The T1 MRI with gadolinium contrast is the most useful study. MRI is not routinely needed to evaluate vertigo or hearing disturbance without accompanying neurological findings. Although the MRI may show enhancement of the vestibular nerve in vestibular neuritis, the expense of this study should be considered when...

Primary Anxiety Disorders

Ated in children and adolescents with comorbid medical conditions that may also be associated with somatic symptoms. The psychological symptoms of anxiety are routinely associated with physical signs of autonomic activity (e.g., palpitations, shortness of breath, tremulousness, flushing, faintness, dizziness, chest pain, dry mouth, muscle tension). The most common somatic symptoms reported by children and adolescents with DSM-IV-TR anxiety disorders (i.e., social, separation, and generalized anxiety disorders) were as follows restlessness (74 ), stomachaches (70 ), blushing (51 ), palpitations (48 ), muscle tension (45 ), sweating (45 ), and trembling shaking (43 ) (Ginsburg et al. 2006).

Syndromes Primarily Involving Vestibular Function

Conditions that involve vestibular function can be separated into peripheral (otological vertigo) and central subgroups. Patients with these syndromes present clinically with a combination of vertigo and ataxia. Practically, there are far more cases of otological vertigo than central vertigo, and for this reason, in clinical practice, a detailed understanding of otological vertigo is essential. BENIGN PAROXYSMAL POSITIONAL VERTIGO Benign paroxysmal positional vertigo is the cause of half of all cases of otological vertigo it accounts for about 20 percent of all patients with vertigo. Benign paroxysmal positional vertigo is diagnosed by the history of positional vertigo with a typical nystagmus pattern (a burst of upbeating torsional nystagmus) on Dix-Hallpike positional testing. Symptoms are precipitated by movement or a position change of the head or body. Getting out of bed or rolling over in bed are the most common problem motions. A burst of nystagmus can often be provoked by...

Proximal Peripheral Lesions

The glossopharyngeal and vagus nerves pass through the area of the cerebellopontine angle, formed by the junction of the pons, medulla, and cerebellum, before exiting the skull through the jugular foramen. In this area, both nerves may be compromised by an expanding mass lesion, most commonly a schwannoma originating from the vestibular portion of the eighth cranial nerve within the internal auditory canal. The syndrome of a cerebellopontine angle tumor generally begins as tinnitus with hearing loss, and dysequilibrium or frank vertigo, which may be episodic. As the tumor expands, the fifth cranial nerve becomes involved, resulting in ipsilateral facial pain and numbness and loss of the corneal reflex. The cerebellum or cerebellar peduncles may become compressed, producing ataxia. Unilateral impingement upon the vagus nerve causes mild

Evaluation Guidelines Table142

Various neuroimaging studies may be useful. y y Plain films of the skull may provide diagnostic information in platybasia (flattening of the base of the skull so that the angle formed by an imaginary line connecting the anterior margin of the foramen magnum, the tuberculum sella, and the nasion is greater than 143 degrees), Paget's disease (areas of increased and decreased bone density, giving the bones a cotton-wool appearance), and basal skull fracture. Head computed tomography (CT) may be diagnostic in meningioma (homogeneous contrast-enhancing lesions with well-defined borders), acoustic neuroma (a well-defined uniformly enhancing tumor in the cerebellopontine angle, along with widening of the internal auditory canal), and skull fracture. Head magnetic resonance imaging (MRI) is useful in the diagnosis of a multitude of lesions including syringobulbia (a syringobulbar cavity), multiple sclerosis (plaques), tuberculous or carcinomatous meningitis (meningeal...

Importance of Early Interests

My colleague, Judy Gelbrich, and I also pointed out that interests which begin in very early childhood are the seeds of creative development. Born of disequilibrium among and between systems of knowledge, affect and other internal systems in interaction with the external world, the child cultivates passionate interest quests around 'centers of action'. Patterns in these quests become apparent quite early with interests clustered around six themes. Similarly, Jonathan Feinstein associated interests from childhood and young adulthood with creative development, wherein passions and interests direct the creator's attention. In the developmental phase, individuals connect to and conceptualize these interests in the exploration phase, they engage with receptiveness in these involvements and develop unique structures in interest areas

Consumption And Unhappy Consciousness

Remedied with a prescription for continued self-indulgence. The outcome is a type of consumer vertigo wherein a disintegrated social reality has been replaced by an intense inquisitiveness about the offerings of the consumer world.14 In the end, we no longer possess the ability to recognize ourselves except as a fluid identity that forms and reforms over the course of endless consumer trials.

Temporomandibular Disorder

Temporomandibular joint (TMJ) dysfunction is a fairly common problem. Patients may present with headache which is localized to the preauricular region, mandible, and TMJ region. In addition to frontotemporal headache, patients often complain of otalgia, tinnitus, and dizziness. Clinical history may elicit symptoms of bruxism during sleep and reported jaw locking or popping. Limited jaw opening and tenderness of the masticatory muscles may be noted during examination. TMJ dysfunction leads to myofascial pain contributing to the symptoms of headache. Symptoms are often self-limited but in persistent cases referral to a TMJ specialist may be required.

Vestibular Neuronitis

Acute vertigo associated with nausea and vomiting (but without neurologic or audiologic symptoms) that originates in the vestibular nerve is known as vestibular neuronitis. Vestibular neuronitis can occur spontaneously or can follow viral illness. Nystagmus is horizontal, with the fast component beating away from the affected side. The symptoms peak within 24 hours and usually last 3 to 4 days. Autopsy studies have shown cell degeneration of one or more vestibular nerve trunks, a finding similar to that seen in Bell's palsy, which affects the facial nerve. A short course (3-5 days) of vestibular suppressants (e.g., meclizine Antivert , diazepam Valium ) and antiemetics such as promethazine (Phener-gan) can provide symptomatic relief in the acute setting. Distinguishing between vestibular neuronitis and bacterial labyrinthitis or labyrinthic ischemia is important. The diagnosis of bacterial labyrinthitis is based on hearing loss and otitis media or meningitis, and labyrinthic ischemia...

Traumatic Tympanic Membrane Perforations

Traumatic perforation of the tympanic membrane may result from barotrauma (water skiing diving injuries, blast injuries, blows to side of head), ear canal instrumentation (cotton-tipped applicators, bobby pins, paper clips, cerumen curettes), or otitis media (see earlier discussion). The patient usually complains of acute pain that subsides quickly, associated with bloody otorrhea. Severe vertigo can occur but is transient in most cases. Persistent vertigo suggests inner ear involvement (perilymphatic fistula). Hearing loss and tinnitus are also common.

The Present and the Future

June 1975 A worker became ill with dizziness and trembling due to high concentration of kepone in his blood. State official investigations found 7 workers ill enough to require immediate hospitalization. Over 100 people, including wives and children, had kepone in their blood, and 30 more people were hospitalized with tremors and visual problems.

Intracranial Liposarcoma

Initial signs and symptoms were consistent with mass lesions within the skull. The 4-month-old girl had macrocra-nium and was vomiting,11 and the 70-year-old woman had dizziness and ataxia.18 Both of these cases were reported in the pre-CT era and were correctly diagnosed only after surgical resection. The 6-month-old girl had partial seizures following

Thesis AntithesisSynthesis Process of Dialectic Thinking

The thesis-antithesis-synthesis dynamic also underpins both Piaget's and Vygotsky's views of how cognitive development occurs. For Piaget development occurs when the stability or equilibrium of the organism is disturbed and a type of disequilibrium occurs. Equilibrium is restored when the organism is able to coordinate and integrate the source of disturbance or contradiction into the overall system. For the organism, stability is its normal state and it seeks this integration. Vygotsky, by contrast, holds that cognitive development is a product of the dialectical interaction between the self (internal) and the environment (external). He introduces the essential role of cultural context into this internal external interaction.

Evaluation Guidelines Table 182

Magnetic resonance imaging (MRI) of the head is indicated for patients in whom the cause of a gait disturbance is not apparent from the history and neurological examination or in whom start hesitation or disequilibrium is evident. Hydrocephalus, frontal lesions, subcortical gray and white matter lesions, and brain stem lesions may be found that were not suspected from the history or physical examination. Computed tomography (CT) of the head reveals less information about white matter and subcortical structures but excludes hydrocephalus, frontal lesions, and large subcortical abnormalities. The presence of spasticity and posterior column signs will direct imaging toward the spine, particularly the cervical region, if no explanation is apparent from brain imaging.

Syndromes of Impaired Adaptation and Deployment of Strategies

Psychogenic gait disorders can take many forms including hemiparetic and paraparetic disorders, ataxic disorders, trembling, buckling of knees, and dystonic abnormalities. Features that suggest psychogenic gait disorders include (1) variability in gait from time to time, particularly with suggestion or distraction (2) excessive slowness and hesitation in walking (3) tandem walking with much arm waving and swing foot wavering combined with prolonged periods of balancing on the stance foot (4) bizarre gait patterns with no explanatory neurological findings and (5) other historical and neurological signs suggesting a psychogenic disorder.y Neurological disorders that are sometimes improperly labeled as psychogenic are (1) dystonia, because the postures may be strange and may be present only during certain specific tasks (e.g., during walking but not running) (2) thalamic astasia, because of the striking evidence of disequilibrium combined with a lack of other neurological signs and (3)...

What do you do now

Pain in the posterior neck or occiput is common, as is generalized headache. Pain often precedes neurological symptoms by hours, days, and, rarely, weeks. Many patients with vertebral artery dissections have only neck pain and do not develop neurological symptoms or signs. Transient ischemic attacks (TIAs), when they do occur, are most often characterized by dizziness, diplopia, veering, staggering, and dysarthria. TIAs are less common in patients with vertebral artery neck dissections compared to internal carotid artery dissections. Infarcts usually cause symptoms and signs that begin suddenly. The commonest locations of ischemic brain damage are the portion of the

The Pediatric Chronic Daily Headaches

Chronic Daily Headache is often accompanied by other chronic symptoms, such as anxiety, depressed mood, dizziness, and fatigue. It has a significant impact on quality of life, as these patients often miss school and become withdrawn from academic and social activities. Complicating factors such as medication overuse also need to be addressed (see Table 7.11).

Vestibular Schwannomas

The terminology for acoustic neuroma tumors has undergone several changes along with discoveries through pathology, specifically electron microscopy. The term neuroma refers to hyperplastic proliferation of nerve fibers and nerve sheaths induced by trauma and therefore is not adequate for these neoplasms. The term neurilemoma has been left, because the neurilemma is the Schwann cell plasma membrane, its lamina, and connective tissue ground substance. Acoustic neuromas are correctly termed vestibular schwannomas. The Schwann cells of peripheral nerve segments give rise to schwannoma formation.

General Management Goals

_TABLE 12-10 -- ON CAUSES OF CENTRAL VERTIGO_ Childhood variant (benign paroxysmal vertigo of childhood) Seizure (temporal lobe) practice to use potentially addictive medications, such as benzodiazepines, in the management of patients with vertigo or imbalance when other medications fail. Although these agents are indispensable in these settings, the doses should be kept low and patient use should be monitored.

Postpartum Hemorrhage

Excessive vaginal bleeding after placental delivery should prompt vigorous fundal massage while the patient is rapidly given 10 to 30 units of oxytocin in 1 L of IV fluid. If the fundus does not become firm, uterine atony is the presumed (and most common) diagnosis. Uterine atony should be initially managed by bimanual uterine massage and compression in addition to the oxytocin. If IV or IM oxytocin proves ineffective, other uterotonic agents, such as methylergonovine and prostaglandin derivatives (15-methyl PGF2a), may be used as second-line treatment (ACOG, 1998a). Methylergono-vine may be administered in a dose of 0.2 mg IM every 2 to 4 hours. Methylergonovine can cause cramping, headache, and dizziness. This agent is contraindicated in hypertensive disease states because it induces vasoconstriction, which can lead to severe hypertension.

Postsurgical Treatment Early Postoperative Therapy

Neuroma is exposed in the cerebellopontine angle and in the internal auditory canal (posterior wall is removed). B, After enucleation of the acoustic neuroma, the tumor capsule is pulled up, and cranial nerves VII and VIII are visible. C, After complete resection of the acoustic neuroma, the nerve bundle of VII and VIII is visible in the internal auditory canal (IAC).

Outcome and Quality of Life

Acoustic neuroma can be cured by complete tumor resection via the suboccipital approach, and the patients will be able to return to their previous quality of life in most cases. The postoperative recovery period is highly variable. Based on a recovery recommended for 2 to 3 months, some patients feel eager and fit to take up their profession after as little as 4 to 6 weeks, whereas others continue to suffer from certain sequels, such as head and neck pains, tinnitus induced or worsened by noises and voices, dizziness, and general fatigue, for 6 months or even longer. Within a rather short period of medical history, the fate of patients with acoustic neuroma has changed dramatically, from suffering a life-threatening disease to a situation where cure and good quality of life are realistic goals.

Facial Nerve Schwannomas

The geniculate ganglion level grow into the middle fossa, and those with proximal origin extend into the internal auditory meatus and cerebellopontine angle. Mean age of patients is approximately 40 years.8,10 Facial palsy occurs in most, but not all, cases it can be absent in up to one quarter. Severity of facial weakness ranges from mild paresis to total palsy. It is usually progressive, often proceeded by periods of facial twitching. Sensorineural deafness is usually present. It can be severe or total. However, it is conductive in some cases and rarely the patient can have intact hearing.8 Other symptoms may include vertigo, tinnitus, or ear pain.10 There is a long interval between onset of symptoms and diagnosis.

Pharmacologic Therapy

Menstrual cycles, and reduces tumor size in 62 of patients. Adverse effects such as nausea, dizziness, and orthostatic hypotension often limit 5 to 10 of patients from continuing treatment. Thus, start bromocriptine at a low dose (e.g., 0.625-1.25 mg) at bedtime (taken with a snack) to decrease adverse effects.41 Slowly titrate up to the optimal therapeutic dose (2.5-15 mg day) because most adverse effects subside with continual treatment.43 If the adverse GI effects are not tolerable, bromocriptine

Transient Ischemic Attacks TIAs

A TIA is a transient episode of focal neurological or retinal dysfunction secondary to impaired blood supply in a vascular territory. Clinical signs typical of TIAs in the carotid and vertebrobasilar territories are outlined in T,aMe.2.2- 2. . It should be noted that transient vertigo, diplopia, dysarthria, or dysphagia in isolation is insufficient to establish a diagnosis of vertebrobasilar TIAs. In addition, isolated drop attacks in which the patient falls to the ground, maintains consciousness, and then arises without a deficit are seldom due to vertebrobasilar ischemia. The annual risk of stroke after a TIA is 3 to 4 percent per year. However, the risk of a subsequent stroke is at least three times greater for individuals who have had a TIA than in those individuals who have not had a TIA. y

Alternative positions for Procedure 2 Retraction and extension

Note Some patients may feel unable to tolerate this exercise when performed supine because of dizziness or nausea. This may pass after repetition as the patient becomes accustomed to the exercise. Should this problem persist in the supine position, the prone lying version should be used.

The vertebral artery VA and the posterior inferior cerebellar artery PICA

Inferior cerebellar lesions in the PICA territory without involvement of the dorsolateral medulla present with vertigo, nausea, vomiting, nystagmus, ipsilat-eral limb ataxia, severe gait ataxia and ocular truncular ipsipulsion. A deceptive appearance of PICA stroke is the isolated vertigo presentation, which can mimic a vestibular neuronitis. One clue which can help to make the correct diagnosis is the presence of an unusual nystagmus, which will be purely horizontal or direction-changing, and preservation of the vestibulo-ocular reflex with the head thrust (Halmagyi) maneuver. This maneuver should not be applied in patients with suspected vertebral artery dissection.

The basilar artery BA

Are nonspecific, such as paresthesias, dysarthria, (herald) hemiparesis or dizziness. More specific prodromes are mentioned above, and also include pathological laughter (fou rire prodromique) 13 as well as pseudoseizures with tonic spasm of the side which will become paretic 14 . Rapid identification of basilar artery ischemia can help to provide aggressive therapy by i.v. or i.a. thrombolysis before a catastrophic picture of a locked-in syndrome or coma. Indeed, it has been shown that vessel recanalization and low NIHSS on admission were independent predictors of favorable outcome 15 .

Understanding How Adjuvant Drugs Relieve Pain and Suffering

May cause dry mouth, urinary retention, drowsiness, constipation, and, rarely, dizziness on standing up suddenly. Orally Gl side effects such as nausea, vomiting and constipation are most common drowsiness, nervousness, dizziness, confusion, stuttering, tremor, and light-headedness may also occur. Topical formulations have no side effects. Rarely, injections can cause seizures.

Diagnosis Clinical Presentation

The clinical characteristics of a glomus jugulare tumor depend on its locally invasive behavior, its anatomic extension, the size of the tumor, and whether it secretes neuropeptide hormones. Most commonly, patients have hearing loss and pulsatile tinnitus or dizziness. Hearing loss is usually unilateral and results from invasion of the middle ear. It can be conductive if the ear canal is obstructed or sensorineural if the cochlea or labyrinth is invaded, and is often accompanied by dizziness. Pulsatile tinnitus occurs in association with a highly vascular lesion, which is seen through an otoscope as a pulsatile reddish-blue mass beneath the tympanic membrane. Occasionally, patients develop otorrhea spontaneously or after a biopsy.

Clinical Manifestations and Pathology

The most frequent clinical findings were fever (97 percent), headache (80 percent), and muscle and joint pain (80 percent). Other signs and symptoms frequently reported were malaise, chills, anorexia, nausea, vomiting, diarrhea, and maculopapular skin eruption (blotchy, raised, red rash). Dizziness, unusual taste sensation, and itching scaling of the palms were less frequently reported. Hemorrhagic signs occurred in 18 patients and consisted of petech-iae (pinpoint hemorrhages into skin and mucous

ECG findings in athletes

Among the total population of athletes there are a few, 2-5 , with highly abnormal ECGs but without clinical symptoms and without evidence of pathologic structural or morphologic changes on echocardiogra-phy. However, in athletes presenting with symptoms such as syncope, near-syncope, sudden dizziness, etc., as for other patients a thorough investigation must be made as arrhythmias can also be symptoms of underlying structural heart disease, such as hypertrophic cardiomyopathy, arrhythmogenic right ventricular

Illustrative Case

A 56-year-old woman who was an ex-smoker was found to have a left lower lobe pulmonary mass 2 cm in maximal diameter. On careful questioning, the patient reported mild disequilibrium. An MRI scan of the brain revealed a solitary lesion 2.5 cm in maximal diameter in the left cerebellum. The remainder of the metastatic work-up revealed no evidence of disease. She underwent craniotomy for removal of the brain metastasis, followed by thoracotomy for resection of the lung primary. The

Clinical Manifestations

Symptoms of eclampsia and preeclampsia include excessive and sudden weight gain, edema, hypertension, and proteinuria. Patients may also suffer from headache, dizziness, visual disturbances, anorexia, nausea, vomiting, upper abdominal pain, and swelling of the face and extremities. In severe cases, women experience visual and neurological disturbances, oliguria (a deficiency of urine excretion), and, of course, convulsions. In addition, cardiac output increases and the kidneys (which seem to be the target organ for the disease) are affected. Eclampsia can lead to lethal complications affecting the liver, kidney, uterus, and brain, such as abruptio placentae, acute renal failure, cerebral hemorrhage, disseminated intravascular coagulation, and circulatory collapse. Preeclampsia does not occur before the twentieth week of pregnancy, and eclampsia rarely before the thirty-second week. Doctors carefully monitor blood pressure and weight gain to prevent its occurrence, although the...

Research Evidence to Date

Studies have assessed acupressure's ability to treat several problems, including morning sickness in pregnant woman, headaches, motion sickness, backache and nausea and vomiting. In the acupressure acupuncture system, nausea is believed to be controlled by a small area on the inside of the wrist called the P6 acupoint. Pressing that point is believed to control nausea, and research backs this belief.

Intracerebral hemorrhage

Hemorrhages into the brain occur unexpectedly and are often lethal events. Typical warning signs are not known rarely a feeling of unsteadiness, dizziness or a tingling sensation can precede an intracere-bral hemorrhage (ICH), but such symptoms do not have localizing value such as in ischemia, where stroke-like warning signs (transient attacks) can occur days or weeks before the onset of a stroke. Often enough only a history of elevated blood pressure is known. Thus, for most patients, it comes out of the blue. The volume of the hemorrhage into the brain is the most decisive prognostic component and when reaching a total volume (such as more than 60 ml within one cerebral hemisphere) that cannot be compensated by intracranial compartmental reserve capacity, the consequences are downward herniation of the medial temporal lobe and compression of the brainstem.

Classification Clinical Manifestations and Pathology

Complex partial seizures are characterized by complex symptoms and, unlike simple partial seizures, by impairment of consciousness. Often the patient appears to be conscious but later has no recollection of the episode. These seizures are usually associated with the temporal or frontal lobe and often begin with an aura that warns of the impending attack. Auras may include any of a large variety of sensations. Some of those most commonly reported are nausea faintness dizziness numbness of the hands, lips, and tongue choking sensations and chest pain. Less often, patients have reported visions, palpitation, or disturbances of smell or hearing. Some patients have sensations that may begin hours or even days before the seizure. These symptoms are called the prodrome and most often involve irritability or feelings of uneasiness. When psychomotor symptoms appear during a seizure, they are generally semipurposeful and inappropriate actions such as clumsy attempts to disrobe. Patients often...

Pulmonary Stenosis with Interatrial Communication

Giddiness, lightheadedness, or syncope may be experienced with exertion. Large jugular venous A waves (see Fig. 16-5) are sometimes subjectively sensed, especially after effort or excitement. Chest pain occasionally resembles angina pectoris attributed to ischemia in the high-pressure hypertrophied right ventricle. Death is due to right ventricular failure, or less commonly to hypoxia, cerebral abscess, or infective endocarditis.12,38,39

Defining The Syndrome Of Panic Disorder

The syndrome now called panic disorder was first described in the medical literature in 1895, by Sigmund Freud (1895a), under the term anxiety neurosis. His description differed from the currently accepted one in Diagnostic and Statistical Manual of Mental Disorders (DSM IV-TR) (APA, 2000), in that he included features of the illness other than panic attacks, including general irritability, anxious expectation, rudimentary anxiety attacks (which bear a similarity to our current conceptualization of limited symptom attacks), vertigo, phobias and agoraphobia, nausea and other gastrointestinal symptoms, and paresthesias.

Course Of Panic Disorder

Visits being precipitated by physical sensations associated with panic disorder, such as dizziness, heart palpitations, chest pain, dyspnea, and abdominal pain, as demonstrated by both epidemiological and retrospective studies (Katon, 1996). Patients with panic disorder account for 20 to 29 percent of all emergency room visits (Swenson et al., 1992 Weissman et al., 1989) and are 12.6 times more likely to visit emergency rooms than the general population (Markowitz et al., 1989).

Psychopharmacological Treatments

Several antidepressant medications and benzodiazepines have been found to be efficacious for panic treatment. Currently, selective serotonin reuptake inhibitors (SSRI's) are considered first-line treatment with regard to issues of safety and tolerability (APA, 1998). Paroxitene (Lydiard et al., 1998), fluvoxamine (Hoehn-Saric et al., 1993), fluox-itene (Michelson et al., 1998), sertraline (Rappaport et al., 1998), and citalopram (Wade et al., 1997) have all been found to be effective in placebo-controlled trials. Of these agents, paroxitene and sertraline are approved by the Food and Drug Administration (FDA) for the treatment of panic disorder. SSRIs were originally thought to have superior efficacy to tricyclic antidepressants, but treatment trials with larger numbers of subjects have suggested they are equivalent (Otto et al., 2001). Despite their overall tolerability, SSRIs may still have troubling side effects. These include sexual dysfunction, gastrointestinal symptoms (although...

Temporal Bone Syndrome

Conductive hearing loss is the most common manifestation of temporal bone metastasis. It is present in approximately 30 to 40 of symptomatic patients and is almost always the result of dysfunction of the eustachian tube with secondary serous otitis media.9,26,61 Sensorineural hearing loss, if it occurs, is usually due to involvement of the cochlear fibers in the internal auditory meatus.61 Maddox emphasized the triad of symptoms of otalgia, periauricular swelling, and facial nerve paresis as being the most suspect for malignant involvement of the temporal bone.41 He reported an incidence of facial nerve paralysis of 34 in his series. Schuknecht et al also reported a high incidence of facial palsy.63 Saito et al found that only 50 of patients with invasion of the facial canal manifested facial paralysis, although 100 of those who had tumors extending beyond the epineural sheath had complete paralysis.60 Much less common findings are otorrhea, vertigo, tinnitus, or a middle ear...

Functional Assessment

Patients respond to different classes of NSAIDs for unknown reasons, and no NSAID appears superior to others in efficacy. Treatment is largely empiric. Most clinicians start with a low dose and titrate upward if needed. An adequate trial of an NSAID requires that the patient take a maximum dose for 3 weeks before changing to a different NSAID, although many patients will expect a change in medication before this. It is usually best to switch to an NSAID from a different class. There is no benefit to combining nonsalicy-late NSAIDs. All COX-1 NSAIDs can cause dyspepsia and GI toxicity, interfere with platelet function, and prolong bleeding times. Other common side effects include renal toxicity and central nervous system (CNS) symptoms such as drowsiness, dizziness, and confusion. A 2004 Cochrane review of NSAIDs for lower back pain concluded that the various types of NSAIDs (e.g., COX-2 inhibitors) are equally effective, and selection of an NSAID for OA should be based on relative...

Neurofibromatosis 2

Neurofibromatosis 2 is an autosomal dominant disorder that occurs with only 10 the frequency of NF1, with an incidence of 1 in 33,000 to 40,000.4 NF2's hallmark is the presence of bilateral acoustic neuromas, which is pathognomonic for the disease. NF2 can also be diagnosed when a first-degree relative with NF2 and either a unilateral acoustic neuroma or two of the following are present neurofibroma, meningioma, glioma, schwannoma, or subcapsular lenticular opacities.1 NF2 is associated with a 90 incidence of spinal tumors (intramedullary, intradural extramedullary, dumbbell, extradural), 33 of which were symptomatic in a series of 48 patients.13 In NF2 patients,

Functional anatomy

Information regarding orientation and movement of the head in space hence balance (equilibrium) is conveyed via the vestibulocochlear nerve (cranial nerve VIII) to the vestibular nuclei in the brainstem. Here, it is integrated with information from the contralateral ear before information is relayed to the cerebellum, primary sensory cortex and motor nuclei in the brainstem. Reflexive connections in the brainstem enable coordinated eye, head and neck movements (via Cranial nerves III, IV, VI and XI) and adjustments to muscle tone via the descending vestibulospinal tract. Lesions result in nystagmus, dizziness, impaired equilibrium reactions and balance, awareness of midline, oculomotor difficulties, impacting on visual processing.

Xanax Valium and Other Sedatives

Motor functions, amnesia, and accidents. When taken during the day for anxiety, the dose is important because the drugs can produce excessive sleepiness. Some drug users take these drugs to get high, and others take them to treat anxiety and irritability associated with use of other drugs. Chronic use, say over several months, can lead to addiction. Withdrawal symptoms include anxiety, agitation, sleep disturbance, muscle cramps, and dizziness. However, if the addict has been using high doses, seizures and delirium are also possible.

Psychology Physician Psychiatrists and the Clinical Association of Genius and Madness
