Week 4 Change From Baseline in Computerized Neuropsychological Test Battery (CNTB): Short CNTB Summary Score.
Lasso di tempo: Baseline and Week 4
|
The CNTB was used to evaluate cognitive function, as measured by the mean change from Baseline to Week 4 in the short CNTB summary score.
The short CNTB summary score was scored as the mean score across 5 modules: Word List Learning-Selective Reminding, Word List Learning-Delayed Recall, Simple Reaction Time, Choice Reaction Time, and Visual Memory subtests.
The short CNTB summary score ranges from 0 to 100, with higher scores (and positive changes from baseline) indicating better performance.

Week 4 Change From Baseline in Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog): ADAS-Cog Total Score
Lasso di tempo: Baseline and Week 4
|
The ADAS-Cog, scored as the total score of 11 tasks including mazes was used to evaluate cognitive function, as measured by the mean change from Baseline to Week 4 in the ADAS-Cog total score.
The ADAS-Cog total score ranges from 0 to 70, with higher total scores indicating more impairment.
Lower scores (and negative changes from Baseline) indicate better performance.

Week 4 Change From Baseline in Cognition Summary Score (CSS)
Lasso di tempo: Baseline and Week 4
|
The CSS was used to evaluate cognitive function as measured by the mean change from Baseline to Week 4 in the CSS total score.
The CSS was derived from the correct sequence percentage from the Route Test and 6 of the CNTB scores (the CSS was scored as the mean of the 7 scores).
CSS scores can range from 0 to 100, higher scores (and positive changes from baseline) indicate better performance.
