Abstract

Objective: To quantify the effects of cognitive training (CT) on cognitive and behavioral outcome measures in patients with Parkinson disease (PD). Methods: We systematically searched 5 databases for randomized controlled trials (RCTs) of CT in patients with PD reporting cognitive or behavioral outcomes. Efficacy was measured as standardized mean difference (Hedges g) of post-training change. Results: Seven studies encompassing 272 patients with Hoehn & Yahr Stages 1-3 were included. The overall effect of CT over and above control conditions was small but statistically significant (7 studies: g 0.23, 95% confidence interval [CI] 0.014-0.44, p 0.037). True heterogeneity across studies was low..
