Risk factors for somnolence, edema, and hallucinations in early Parkinson disease

Abstract
Background: The CALM-PD trial evaluated the development of motor complications in subjects with early Parkinson disease (PD) randomized to initial treatment with either pramipexole or levodopa. A secondary finding of the trial was a higher than anticipated development or worsening of somnolence and edema and development of hallucinations.
