Impact of Switching to Continuous Release Dopamine Agonists

The purpose of this proposal is to determine if switching PD patients treated with pramipexole to ropinirole CR reduces the non-motor side effects frequently experienced by these patients. Side effects that we will monitor in particular include somnolence, peripheral edema, cognitive decline with and without hallucinations. PD patients followed in the MUO Neurology Clinic who are being treated with pramipexole and have evidence of at least one of the following symptoms: somnolence, cognitive impairment with or without hallucinations, or peripheral edema will be offered the opportunity to participate in this study.
