Performance on neuropsychological testing is worse with increasing radiation dose to the hippocampus from Redmond et al.31 The performance on the Purdue Pegboard both hands test (Z-scores), a measure of motor dexterity and speed, at 6 months following completion of RT relative to (A) mean left hippocampal radiation dose, P = 0.049, and (B) mean right hippocampal radiation dose, P = 0.032 is shown. Standardized scores were used in this analysis to account for the effect of age on test performance.
