Randomized Controlled Trial Multicenter Study
Risk factors for somnolence, edema, and hallucinations in early Parkinson disease.
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. ⋯ Comorbid illnesses are important and overlooked risk factors for the development of somnolence, edema, and hallucinations. When initiating therapy with pramipexole, patients should be counseled about and monitored for somnolence and edema. Slight decrements in cognitive function and older age are associated with an increased risk of hallucinations.
