Wechsler Adult Intelligence Scale - IV: Symbol Search Scaled Scores Means and Standard Deviations at the following timepoints: Infusion 1/Baseline (Visit 3 - Week 0), 6 months Post-Infusion (Visit 6 - Week 28), 1 year Post-Infusion (Visit 7 - Week 56). The subsection (such as Coding) raw scores are converted into a scaled score with a mean of 10 and a standard deviation of 3. This process is standardized using age-based conversion tables. Then, these scaled scores are combined into index scores which are compared to a normative population with a standard score (mean = 100, SD = 15) to create an index score and fall into ranges of "Average" being 90-109, "High Average" 110-119, "Low Average" 80-89, "Borderline" 70-79, and "Extremely Low" below 70. Higher scores mean better outcome.

Controlled Oral Word Association Test (COWAT) Total Scaled Scores Mean and Standard Deviations at the following timepoints: Infusion 1/Baseline (Visit 3 - Week 0), 6 months Post-Infusion (Visit 6 - Week 28), 1 year Post-Infusion (Visit 7 - Week 56). The COWAT is scored by counting the number of correct words a person produces in one minute for each of the three given letters. The total score is the sum of the unique words generated across all three trials. Higher scores are considered a better outcome. The raw total score is then compared to normative data that is based on factors such as age and education level. The scaled score has a mean of 10 and a standard deviation of 3. A t-score of < 20 indicates severe impairment.
