“…Z-scores for the neuropsychological domains and measures were computed based on standardized norms adjusted for age [Stroop (Golden, 1978), Short Categories (Wetzel & Boll, 1987), PASAT (Stuss et al, 1988), Block Design (Wechsler, 1997), and Rey (Denman, 1987)], years of education [AMNART (Grober & Sliwinski, 1991)], age and years of education [Symbol Digit Modalities (Smith, 1982), MicroCog (Powell et al, 1993)], and age, gender, and years of education [(Trails A and B (Heaton et al, 1991), COWAT (Ruff et al, 1996)]. The Stroop, Symbol Digit Modalities, and the MicroCog test norms are not specific to gender, since gender did not significantly affect scores in the normative samples (Golden, 1978;Powell et al, 1993;Smith, 1982).…”
