Statistical Analyses: A 2 (group) x 3 (testing sessions: baseline, 15 days, 37 days) repeated measures ANOVA will be performed. We hypothesize that there will be a significant interaction of time of testing by group. Cognitive performance is expected to improve from the 1st to the 2nd testing sessions in the group 1, with just a mild practice effect documented in the group 2. Additionally, we expect a return to baseline cognitive functioning from the 2nd to the 3rd NP assessment in Group 1, with an improvement in performance noted in group 2 due to medication effects. No main effects are anticipated. A linear regression will be used to examine the influence of memory performance and perception of memory abilities on changes in depression and anxiety at the various assessment intervals. We hypothesize that as memory improves, depression and anxiety levels will decrease. Additionally, as the perception of memory improves, depression and anxiety will also decrease.
