ABSTRACT

Huntington's disease (HD) is an inherited neurodegenerative disease characterized by motor, cognitive and behavioral deficits. Some evidence suggests that the endocannabinoid system participates in the pathophysiology of HD. We conducted a cross-sectional study comparing plasma levels of anandamide and 2-arachidonoylglycerol in manifest HD gene-expansion carriers (HDGEC) and healthy controls, finding no difference in endocannabinoid levels between the groups. Correlations between endocannabinoid levels and clinical scales (Mini-Mental State Examination, Hospital Anxiety and Depression Scale, Unified Huntington Disease Rating Scale) were non-significant. We found a significant association between body mass index and anandamide levels in healthy controls but not in HDGEC.

ABSTRACT

BACKGROUND: REM sleep behaviour disorder (RBD) is a common non-motor feature of Parkinson's disease (PD). Cannabidiol (CBD) is one of the main non-psychoactive components of Cannabis sativa and may represent an alternative route for treating RBD. OBJECTIVE: This study assessed the efficacy and safety of CBD for RBD in PD. METHODS: We conducted a phase II/III, double-blind, placebo-controlled clinical trial in 33 patients with RBD and PD. Patients were randomized 1:1 to CBD in doses of 75 to 300mg or matched capsules placebo and were followed up for 14 weeks. The primary outcomes were the frequency of nights with RBD, CGI-I, and CGI-S. RESULTS: CBD showed no difference to placebo for primary outcomes. Regarding secondary outcomes, we observed a significant improvement in average sleep satisfaction from the 4th to 8th week in the CBD versus placebo group with P = 0.049 and P = 0.038, respectively. CONCLUSION: CBD, as an adjunct therapy, showed no reduction in RBD manifestations in PD patients. A transient improvement in sleep satisfaction with a dose of 300mg has been noted. © 2021 International Parkinson and Movement Disorder Society.
