Medicinal cannabis improves outcomes in Parkinson's patients
With medicinal cannabis now legalized in many parts of the world, there is growing interest in its use to alleviate symptoms of many illnesses including Parkinson's disease (PD).
According to results of a survey of PD patients in Germany in the Journal of Parkinson's Disease, over 8% of patients with PD reported using cannabis products and more than half of those users (54%) reported a beneficial clinical effect.
Cannabis products containing THC (tetrahydrocannabinol, the main psychoactive compound of cannabis) can be prescribed in Germany when previous therapies are unsuccessful or not tolerated, and where cannabis can be expected with not a very unlikely chance to relieve disabling symptoms.
CBD (pure cannabidiol, derived directly from the hemp plant, a cousin of the marijuana plant) is available without a prescription from pharmacies and on the internet.
Investigators aimed to assess patient perceptions of medicinal cannabis as well as evaluate the experiences of patients already using cannabis products. They performed a nationwide, cross-sectional, questionnaire-based survey among members of the German Parkinson Association (Deutsche Parkinson Vereinigung e.V.), which is the largest consortium of PD patients in German-speaking countries with nearly 21,000 members. Questionnaires were sent out in April 2019 with the association's membership journal and were also distributed in the investigators' clinic.
