Abstract

A battery of neuropsychological tests was administered to 22 nonalcoholic sons of male alcoholics (SOMAs) from families with extensive histories of male alcoholism and to 22 nonalcoholic controls with no history of familial alcoholism. In each group 11 subjects were tested while sober and 11 were tested while alcohol-intoxicated. Analyses of the results of this battery suggested (1) that SOMAs may be characterized by comparative decrements in those cognitive functions associated with the organization of novel information, dependent in theory upon the prefrontal cortex; and (2) that alcohol detrimentally affects delayed memory, associated with the temporal cortex, equally across groups. Of these SOMAs 20 had previously participated in one of two studies that demonstrated their cardiovascular hyper-reactivity to threat/stress and their increased sensitivity to the reactivity-dampening effects of alcohol intoxication. Correlational analyses of the results of the present and previous studies demonstrated the existence of a highly significant relationship between cognitive impairment, cardiovascular hyper-reactivity and susceptibility to the reactivity-dampening effects of alcohol.
