clinically impaired scores of ≤ 10% ile or -1.3 SDs below control mean; Norms used: RCFT [21]; LM [7]; RMT [23]; GNT [25]; Letter fluency [27], Category fluency [26]; WCST [28]. For RCFT – copy, all scores reflect performances ≥ 16th%ile unless marked otherwise. For RMT, age-adjusted percentiles only include 40-54 years and 55 years and above.
