Main effects of group on neuropsychological (Trails A and B, Digit Span (Forward and Backward), Category Fluency, Letter Fluency, and Visuospatial Sequencing Test (VST, Forward and Reverse)) and impulsivity (Delay Discounting Task) test scores were analyzed using UNIANOVA with group and age bin included as fixed factors and gender as a covariate. Group values are mean(SD).
