A new study published in the Journal of Clinical Pharmacy and Therapeutics suggests cannabidiol (CBD) may help ease sleep problems in Parkinson's disease patients. In the six week study at the University of Sao Paulo in Brazil, four patients suffering from Parkinson's disease who also exhibited symptoms of REM sleep behavior disorder received CBD. At the conclusion of the period, all four patients witnessed reduced symptoms as a result of the medication.

Investigators don't fully understand how CBD is able to offer its therapeutic effects, but they hypothesize it is because of the cannabinoid's anticholinergic activity. While the authors think continued research is still necessary, they do believe CBD provided effective relief for patients, saying, "Four patients treated with CBD had prompt and substantial reduction in the frequency of RBD-related events without side effects...Regarding symptoms after drug discontinuation, RBD complex movements returned with the same frequency and intensity of baseline after the treatment was interrupted."
