CBD's potential impact on Parkinson's disease: An updated overview

Area of Science:

• Neuroscience
• Pharmacology

Background:

• Parkinson's disease (PD) presents significant motor and non-motor symptoms impacting quality of life.
• Current treatments like l-DOPA have limitations and side effects, necessitating alternative therapies.
• Cannabidiol (CBD), a non-psychoactive cannabis compound, is being investigated for its therapeutic potential.

Purpose of the Study:

• To review the efficacy of CBD in managing both motor and non-motor symptoms of Parkinson's disease.
• To consolidate findings from preclinical studies and clinical trials on CBD for PD.

Main Methods:

• Systematic review of preclinical animal studies.
• Analysis of available clinical trial data on CBD in Parkinson's disease patients.

Main Results:

• Preclinical studies indicate potential benefits of CBD for PD.
• A limited number of clinical trials (seven) exist, hindering definitive conclusions on efficacy.
• Data on CBD's impact on both motor and non-motor symptoms is still emerging.

Conclusions:

• CBD demonstrates therapeutic promise for Parkinson's disease based on preclinical evidence.
• Further extensive clinical research is crucial to validate CBD's efficacy and safety in PD patients.
• Identifying research gaps is essential for future studies on CBD's role in treating PD symptoms.
