Drug and alcohol use and neuropsychological performance in asymptomatic HIV infection
Abstract
The effect of drug and alcohol abuse on neuropsychological performance was examined in 132 human immunodeficiency virus-seropositive gay or bisexual men. Syndromal (diagnostic) criteria of alcohol/drug abuse based on DSM-III-R were used, and quantitative estimates of alcohol consumption were obtained. Very few differences appeared between substance abuse subgroups formed on the basis of recency or severity of drug use. There were some correlations with the quantitative estimate of alcohol use, but not on the measures previously found to differentiate seronegative and asymptomatic seropositive gay men. These data indicate that alcohol use does affect neuropsychological performance but does not account for the differences observed in studies of seronegative and seropositive subjects.
