Three-Month Change in Performance by Allele and NHPA Score.

Mean difference in scores for RBANS, Stroop, and TMT tests from baseline to 3 months postdiagnosis by individual low- (LPA) and high- (HPA) performing BDNF, COMT, and DRD2 alleles along with total number of high-performing alleles (NHPA) (LPA = NHPA 0 to 4, HPA = NHPA 5 to 6). A indicates attention; CN, color naming; CO, coding; CW, color-word condition; DM, delayed memory; DS, digit span; FC, figure copy; FR, figure recall; IM, immediate memory; LA, language; LL, list learning; LO, line orientation; LR, list recall; Lrecog, list recognition; INT, interference; PN, picture naming; RBANS, Repeatable Battery for the Assessment of Neuropsychological Status; SF, semantic fluency; SM, story memory; SR, story recall; TMT, Trail Making Test; VS, visuospatial; WR, word recognition. *P < .05; ^**P < .01.
