To determine the relative utility of the dietary and ataxia criteria in identifying alcohol-related cognitive and motor impairment we compared 4 alcoholic subgroups: (1) ALCs who met neither diet deficiency nor ataxia criteria (n=21), (2) ALCs who met only the dietary criterion (n=27), (3) ALCs who met only the ataxia criterion (n=12), and (4) ALCs who met both criteria (n=21). Groups differed on Production (F(3,77)=3.30, p=.025), Immediate Memory (F(3,76)=2.89, p=.041), and Upper Limb Motor (F(3,77)=3.00, p=.036) composite scores (Figure 3), with modest differences noted on Attention/Working Memory (F(3,76)=2.40, p=.074) and Delayed Memory (F(3,76)=2.64, p=.057) composite scores. Groups did not differ on Visuospatial Construction composite score (F(3,77)=.306, p=.821).
