Clinical and Electrophysiological Characteristics of Alcoholic Neuropathy

ABSTRACT

Authors analyzed clinical and electrophysiological features of 35 patients with alcoholic neuropathy who had visited the Boramae City Hospital. All patients were men. Most of the cases drank alcohol everyday. The duration of alcohol consumption is from 2 to 47 years (mean, 17.8 years). Patients with relatively short history of alcohol consumption had a tendency to take more inadequate meals. Clinically we found two distinct separable categories ; one was sensorimotor peripheral neuropathy associated with other alcoholic complications, such as Wemicke and Pellagra disease, delirium tremens, liver disease etc(24 patients). The other had subacutely progressing prominent weakness with sensory change, especially in lower extremities(ll patients). Electrophysiological studies showed decreased amplitudes of sensory or motor compound action potentials with relative preservation of conduction velocity favoring axonal neuropathy. Among the electrophysiological parameters, abnormalities in F-wave(78.3%), H-reflex(86.4%) and sural nerve conduction studies(78.8%) were more frequently observed than in others, which were thought to be more sensitive parameters with early involvement. In terms of electrophysiological pattern there were no definite diffemeces between the two groups.
