motor performance among patient subgroups: individuals with alcoholism who did not meet any criteria performed at levels equivalent to healthy controls, whereas patients with one sign showed mild-to-moderate neuro psychological deficits, and patients with two or more signs showed the most severe deficits on each neuro psychological domain evaluated. This graded effect suggests that the heterogeneity in the severity of cognitive and motor deficits seen in patients with uncomplicated alcoholism can be accounted for, in part, by the number of WE signs present.
