Premature Aging in Male Alcoholics: “Accelerated Aging” or “Increased Vulnerability”?

Abstract

This study involved an evaluation of two versions of the “premature aging” theory of chronic alcoholism: the accelerated aging and increased vumerabHty versions. The major dependent measures used were the tests included in Reitan's brain age quotient (BAO), a series of neuropsychological tests known to be sensitive to the effects of alcoholism and aging. Subjects were 40 chronic alcoholic inpatients and 40 matched controls, divided into age groups by; decade, ranging from the 30s to the 60s. It was proposed that an j interaction between age and presence or absence of alcoholism, with BAO test differences between alcoholics and controls widening as age increases, would support the increased vulnerability version, while the absence of such aw interaction would support the accel-] erated aging version. The results dearty favored the accelerated aging version, with merited BAO test differences between alcoholics, and controls appearing even in the 30-year-old groups. It was concluded that chronic ateohoftcs tend to perform at levels found for nonalconoiics 10 years their senior, but the discrepancy between, alcoholics and nonalcohoics does not increase with age.
