Olfactory Function in Chronic Alcoholics

Abstract

8 patients participating in an outpatient program for chronic alcohol abuse and 8 age-matched controls were tested for olfactory function. There was a significant difference between the two groups on a match-to-sample test using uncommon odors but not on a smell identification test using common odors. Ability to detect and identify common odors does not appear to be impaired by chronic alcohol abuse. Deficits on the odor-matching task may be related to difficulty in encoding olfactory information rather than a primary olfactory deficit.
