title: [Differential diagnosis, pathogenesis and therapy of alcoholic polyneuropathy].
abstract: The most common forms of polyneuropathies are the alcoholic and diabetic polyneuropathies. They each constitute 1/3 of all polyneuropathies. The first symptoms shown by the alcoholic polyneuropathy are symmetric sensory disturbances with loss of tendon reflexes and of vibration sense in the peripheral segments of the lower extremities. At the beginning one almost always finds pressure pain in the calves. Important differential clues in diagnosis compared to the diabetic neuropathy, are the age at which the disease begins, the degree to which the autonomic nerve fibres and the cranial nerves are affected, as well as the form of manifestation. Pathogenetically, a direct toxic alcohol effect can above all be suspected in accordance with the typical electrodiagnostic findings with a neurogenic pattern in the EMG in the case of normal or slightly diminished conduction velocity, and in agreement with the morphological finding of an axonal degeneration in most of the biopsies. Possibly, in a small number of cases a vitamin deficiency or a malabsorption can play a causal role. The prognosis is good by complete abstinence from alcohol.
