Manaus, Brazil: The administration of oral doses of CBD is ineffective at reducing the severity of restless legs syndrome (RLS) in patients with Parkinson’s disease (PD) and REM sleep behavior disorder (RBD), according to clinical trial data published in the journal Cannabis and Cannabinoid Research.
Brazilian researchers compared the use of CBD versus a placebo over a 14-week period. Patients in the CBD arm of the trial received up to 300mgs of cannabidiol.
Patients who were administered CBD demonstrated no improvements compared to those receiving placebo.
“CBD showed no reduction in the severity of RLS manifestations in patients with PD and RBD,” authors concluded.
