Table 2.

Neuropsychological Test Scores. WMS scores for patients EE555 and TQ591. Scores are from auditory subtests. WM=working memory; recog=recognition; norm=normal; abn=abnormal. Note that scores are index scores in which 100 is the population average, except for forward and backward digit span which are the raw digit lengths. CVLT-II scores represent normalized performance with 0 representing the population mean and a standard deviation (sd) of 1. Z-scores greater than 2 sd below control performance are considered abnormal. Adnormal scores are indicated by bold font.
