Neuropsychological consequences of posttreatment drinking behavior in male alcoholics

A prospective study was designed to determine the neuropsychological consequences of continued alcohol consumption after treatment for alcoholism. Performance on 24 commonly used clinical neuropsychological tests was examined in 56 male alcoholics approximately 7 months after completion of an inpatient alcoholism treatment program. Abstainers (n = 17) performed better than those who resumed alcohol consumption. Although there was a significant decrease in alcohol consumption, posttreatment drinking behavior still predicted cognitive performance, with increased frequency and quantity per occasion having more deleterious consequences even at consumption levels that are deemed by some to be socially acceptable. It is concluded that alcohol consumption by former alcoholics might serve to maintain cognitive performance at reduced levels, and that this possibility should be considered in determining appropriate treatment goals for alcoholic patients.
