Toxic Neuropathies

Toxic neuropathies occur from repeated exposure to drugs, industrial toxins, or heavy metals (Box 42-22). Presentation depends on the exact exposure and what part of the nerve is affected. It may present as a progressive, symmetric, ascending polyneuropathy, as in many occupational exposures, or with vague sensory changes similar to those of nutritional neuropathies. Lead intoxication creates a motor neuropathy starting in the upper limbs, affecting the radial nerve and causing wristdrop. Many of these neuropathies slowly improve once the offending agent is removed; however, this is not always the case. A careful medical and occupation history is important. Treatment is directed accordingly.
