Brain-age quotients in recently detoxified alcoholic, recovered alcoholic and nonalcoholic women

Examined performance of three matched groups (N = 35 each) of female alcoholics (average sobriety 1 month), female recovered alcoholics (average sobriety 1 year), and female nonalcoholic controls on the Brain-Age Quotient (BAQ), an age-adjusted index of cerebral dysfunction. The mean BAQs of the alcoholics and recovered alcoholics were significantly lower than that of the controls. Analyses of the BAQ subtests indicated that the alcoholics performed significantly less well than the controls on the Halstead Category Test, Tactual Performance Test-Time, WAIS Block Design and WAIS Digit Symbol, which replicates findings with male alcoholics. The recovered alcoholics performed at the alcoholic level on WAIS Block Design and Digit Symbol and performed at the control level on the Halstead Category test; which suggests a differential recovery of cognitive abilities in abstinent female alcoholics.
