This is a randomized, double-blind, placebo-controlled, parallel group study. The use of placebo is appropriate to minimize bias related to treatment expectations of the subject, study partner, and site investigator, as well as to changes in the relationship between the subject and study partner that might occur with the initiation of treatment and expectation of improvement in motor symptoms or cognition. Changes in subject/study partner interactions can impact subject mood and might introduce biases that cannot be quantified. The double-blind use of placebo will also prevent bias in the clinical and scientific assessments.
