[Neurologic sequelae of alcohol].

The consequences of alcoholism on the peripheral and central nervous system are discussed. Polyneuropathy is present in 30% of the alcoholics, whilst cranial nerve involvement is found in 5-25%. Alcoholic myopathy is only very rarely seen. Wernicke's encephalopathy is found at post mortem investigation in 1.8% of alcoholics, but is rarely clinically diagnosed. The Marchiafava-Bignamy syndrome and central pontine myelinolysis are rarely seen; alcoholic amblyopia which is seen in 0.5% of the hospitalised alcoholics is more frequent, but still a rare finding. Cerebral seizures are common in chronic alcoholics with an incidence varying from 5 to 37% according to the type of drinking habit and have, thus, to be categorised. Brain atrophy is a common finding and correlates with the duration and extent of the alcoholism.
