These results extend prior findings of alcohol-related olfactory deficits, indicating impairments in olfactory processes of odor familiarity and edibility in alcohol-dependent patients. Although the basis of these deficits is still unknown, our finding of a distinct pattern of olfactory functional impairment and sparing (intensity, pleasantness) [corrected] suggests that there is no generalized [corrected] olfactory dysfunction, but [corrected] neural olfactory networks may be affected differently. However, alcoholism appears to be associated with a variety of disturbances in olfactory processing [corrected]
