Change in Quality of Life in Neurological Disorders Cognitive Function Version 2 (Neuro-QoL CF v2) T-scores at 6 Weeks Primary · Baseline and 6 weeks

Neuro-QoL CF v2 measures self-reported levels of cognitive functioning. Raw scores are converted to standardized T-scores (mean of 50 with a standard deviation of 10). Increase in T-scores from baseline indicates improvement in everyday cognitive functioning.

Change in Composite Executive Function T-scores at 6 Weeks Secondary · 6 weeks

T-scores (mean of 50 with a standard deviation of 10) of executive function tests (i.e., Stroop, F-A-S letter fluency, and Trail Making B tests) were averaged to obtain a composite executive function score for each subject. Higher scores indicate better executive function.
