Treatments for Insomnia in Patients With Parkinson's Disease

More than half of patients with Parkinson\'s have troubles with insomnia. There are several treatment options for insomnia that have been studied in the general population - however, the investigators don\'t know if these treatments work for patients with Parkinson\'s. It is possible that people with Parkinson\'s may have different treatment responses. The goal of this project is to test in a pilot study the tolerability and effectiveness of pharmacologic and non-pharmacologic treatments to improve insomnia in patients with Parkinson\'s disease. Each participant in this study will be wearing a wrist actigrapch and fill out the sleep diary. Three main treatment strategies will be tested: Placebo Light therapy, Cognitive behavioural therapy and active light therapy, and insomnia medications. The treatment that each person will receive first will be chosen randomly. If the first therapy has not been effective, participant may choose to re-enrol in the trial with one of the remaining two therapies.
