Change in Hopkins Verbal Learning Test (HVLT) Total Recall Score

Verbal memory was measured with the Hopkins Verbal Learning Test (HVLT) total recall scores. The HVLT form contains 12 nouns, four words each from one of three semantic categories (e.g., precious gems, articles of clothing, vegetables, etc.), to be learned over the course of three learning trials. When scoring the HVLT, the three learning trials are combined to calculate a total recall score. Total scores range from 0-36 with higher scores indicating better outcome.

Time frame: Measured at Baseline and Week 24

Change in Delayed Recall Cognitive Domain Scores

Delayed Recall Cognitive Domain score was constructed from: HVLT Delayed Recall, Rey-Osterrieth Complex Figure Test \[30-minute Delayed Recall\], WMS-IV Logical Memory II Delayed Recall. Raw scores were transformed to z-scores (with a mean of 0 and standard deviation of 1) for each test score of interest across all participants. A z-score of 0 represents the sample mean. These z-scores were then averaged to produce a Delayed Recall Cognitive Domain score. Higher Delayed Recall Cognitive Domain scores are indicative of better performance.

Time frame: Measured at Baseline and Week 24

Change in Executive Function Cognitive Domain Scores

Executive Function Cognitive Domain score was constructed from: Trail Making Test A and B, Stroop Interference \[Golden version\] and FAS. Raw scores were transformed to z-scores (with a mean of 0 and standard deviation of 1) for each test score of interest across all participants. A z-score of 0 represents the sample mean. These z-scores were then averaged to produce an Executive Function Cognitive Domain score. Higher Executive Function Cognitive Domain scores are indicative of better performance.
