结局指标
主要结局
Improvement of Cognitive Performance (Change From Baseline in Neuropsychological Computerized Test)
时间窗: Base line and 12 weeks
The computerized neuropsychological assessment software consists of seven separate tasks: symbol spotting, pattern identification, pattern recall, digit-symbol substitution, digits span forward, digits span backward and delayed pattern recall. Based on the results obtained in the single tasks, eight cognitive composite scores are calculated including focused attention, sustained attention, memory recognition \& recall, visuospatial learning, spatial short term memory, executive functions and mental flexibility.The total score range is from 0 to 100 points(0 is worse, 100 is best).
