title: Neuropsychological correlates of chronic alcoholism and aging.
abstract: Independent investigations of alcoholism and aging have demonstrated significant parallels between the two phenomena suggesting the possibility of "premature aging" as a result of alcoholism. To test this hypothesis a cross-sectional design was utilized with three groups of 20 male subjects: young normal (mean age 31 years), young alcoholics (mean age 33 years), and elderly normal (mean age 71 years). Eleven objective measures, selected from a battery of sensory and perceptual motor tests routinely used to evaluate cerebral dysfunction in hospitalized patients, were compared for the three groups. The results indicated a definite general decline in neuropsychological functioning with aging and suggested a similar trend with alcoholism. The tendency seen with alcoholism was least apparent with regard to fundamental sensory-motor functions and the perceptual functions of vision and audition and most apparent with regard to short term memory and abstract reasoning, i.e., higher mental processes. The results provided support for the hypothesis that chronic alcoholism causes premature aging of neuropsychological functions and possibly the brain.
