Autonomic neuropathy in an alcoholic population

Abstract

Autonomic nervous system integrity has been assessed in 30 alcoholic subjects and 30 age-sex matched controls using five simple tests of cardiovascular responses. There was evidence of parasympathetic neuropathy alone in five of the alcoholic subjects (16%) and of combined parasympathetic and sympathetic neuropathy in an additional six (20%). None of the controls showed any abnormality. Within the alcoholic group, those with autonomic neuropathy were older, were more likely to be female and to have established alcoholic liver disease. Symptoms were a poor guide to the presence or absence of autonomic neuropathy.
