Abstract

This study compared variance accounted for by neuropsychological tests in both a brief motor battery and in a comprehensive neuropsychological battery. 327 HIV+ subjects received a comprehensive cognitive battery and a shorter battery (Timed Gait, Grooved Pegboard, and Fingertapping). A significant correlation existed between the motor component tests and the more comprehensive battery (52% of variance). Adding Digit symbol and Trailmaking increased the amount of variance accounted for (73%). Motor battery sensitivity to impairment diagnosis was 0.79 and specificity was 0.76. A motor battery may have broader utility to diagnose and monitor HIV related neurocognitive disorders in international settings.
