Note: measures for Trail A, Trail B, SRT, and CRT represent response time. Thus, positive values for change indicate cognitive decline. All other measures (SDMT, Imm. Rec., STW, Digit Back., and PPEG (both hands)) represent number of items completed correctly (negative values for change indicate cognitive decline).
