The pattern of cognitive impairment in our alcoholics involving executive functions, episodic memory, and visuospatial construction and the graded effect observed related to number of Caine criteria met are consistent with earlier reports (e.g., Beatty et al., 2000; Oscar-Berman & Marinkovic, 2007; Parsons & Nixon, 1993; Pitel et al., 2011; Sullivan, Fama, Rosenbloom & Pfefferbaum, 2002; Sullivan, Rosenbloom & Pfefferbaum, 2000) and provide support for assuming that our alcoholics are representative of other samples. This study replicates and extends previous work (e.g., Pitel et al., 2011; Ritz et al., 2016) addressing the heterogeneity of cognitive and motor deficits in alcoholism and demonstrating that alcohol-related factors and not a history of drug dependency likely underlie these impairments. Here, we identified that dietary deficiency and signs of cerebellar dysfunction, the two most frequently met criteria, significantly predicted cognitive and motor performance. Cerebellar signs of ataxia, more so than dietary deficiency, were associated with deficits in attention/working memory, production, and upper limb motor function, consistent with evidence for an association between higher-order cognitive function and cerebellar integrity (cf., Fitzpatrick and Crowe, 2013).
