SUMMARY
1. Alcohol is directly toxic to both nerves and muscles and causes many kinds of neuropathies (peripheral, autonomic, compressive). Neuropathy is detected in 25-66% of alcoholics in EMG.
2. The polyneuropathy is typically axonal but is made worse if demyelination is superimposed (caused by nutritional deficiencies).
3. Pathogenesis: toxic effect of ethanol, thiamine deficiency, possible thiamine utilization defect, increased protein-kinase-C activity, myelin dysfunction.
4. Presentation: painful, symmetric, length-dependent sensory (more than motor) & autonomic dysfunction.
5. Treatment: cessation of alcohol intake, dietary advice, vitamin supplementation, symptomatic pain releif (with anti-neuropathic agents, opioids).
6. Note: Acute thiamine deficiency presents as Wernicke's: polyneuropathy (weakness of extraocular muscles & ataxia) assoc. with delirium.
