Neuropsychological Test Battery.

BMIPB—BIRT Memory and Information Processing Battery; DS-F—digit span (forwards); DS-B—digit span (backwards); LM-I—Logical Memory (Immediate); LM-D—Logical Memory (Delayed); VR-I—Visual Reproduction (Immediate); VR-D—Visual Reproduction (Delayed); SOIP-M—Speed of Information Processing Motor control task; mWCST—modified Wisconsin Card Sorting Test.
*The mWCST, selected because it is shorter yet retains the original task's lack of transition instructions, was scaled relative to a single published control group of comparable age and gender.
+The two task components were transformed to z-scores and a mean average composite mWCST score used. This composite mWCST measure is included in the global cognition index, not the separate sub-measures.
