Two Case Studies Of Mesodiencephalic Lesions

These case studies might traditionally fall under the province of behavioral neurology, but they provide important clues about the integrative functions necessary for conscious states supported in deep mesodiencephalic regions, in the midbrain structure of periaqueductal gray, and in the intralaminar thalamic nuclei. Case study 3.2 presents some of the most fascinating and little appreciated clinical data on disorders of consciousness stemming from ILN lesions. Both cases studies show akinetic mutism (AKM), one transitionally, one apparently more permanently. AKM is an important syndrome for both psychiatry and neurology, informing us about how consciousness is underpinned and driven at a most basic level by emotion. Stripped of motivation or emotion, consciousness appears to virtually empty out. AKM has obvious and important clinical parallels to common psychiatric problems of severely retarded depression, catatonia and schizophrenia, and other apathy states.
