Cognitive Effects of Rasagiline in Mild-to-Moderate Stage Parkinson's Disease Without Dementia.

The authors studied the effects of rasagiline on cognition in a sample of 50 nondemented patients with mild to moderate Parkinson's disease (PD) using a double-blind, placebo controlled design. Cognition and motor symptoms were assessed at baseline and after 6 months of receiving either rasagiline or placebo. Participants receiving rasagiline showed improvement in their motor symptoms of PD compared to participants receiving placebo. No significant changes in performance on neuropsychological measures of cognition were observed between the groups. Rasagiline is an effective treatment for the motor symptoms of PD. Rasagiline did not appear to affect cognition during this 6-month study.
