Can cannabis light (CBD) improve the quality of life for Parkinson's patients?
Over the past 10 years there has been a significant increase in the popularity and consumption of cannabis, both for recreational and therapeutic purposes. More and more research is confirming the therapeutic properties of Cannabis and its active chemical compounds. Among the latter we find cannabidiol, with the abbreviation CBD. This cannabinoid has potential medical applications, including that for treating symptoms related to Parkinson's disease.
CBD is one of the hundred active cannabinoids present in Cannabis and represents 40% of the plant extract of this plant. One of the main reasons why CBD is now being researched in the medical field is that, unlike the more popular THC (the "recreational" component), it is not psychoactive. Put simply, CBD doesn't bust. This is a very important aspect in clinical therapies, where we always try to minimize side effects. According to numerous studies, even at high dosages, CBD is well tolerated by our body and, therefore, safe for human consumption. Some of the most important therapeutic properties of CBD are the reduction of nausea, anxiety, depression, the contrast of the development of cancer and cancer cells and other important properties found in the scientific literature. Unfortunately, most of these clinical trials come from animal testing, while exhaustive research has not yet been conducted on humans. Furthermore, CBD remains illegal in many parts of the world, a further reason why this field of research should be investigated and the effects on human health and potentially treatable pathologies verified.
CBD AND PARKINSON'S DISEASE
According to several studies conducted in Brazil, Israel, Czechoslovakia, Spain and Italy (indicated below) by independent teams, cannabidiol treatment can improve the quality of life of Parkinson's patients. Some animal studies also confirm that cannabis compounds have the ability to slow the progression of Parkinson's disease and other neurodegenerative diseases.
"Survey on Cannabis use in Parkinson's disease: Subjective improvement of motor symptoms"
Edited by: Charles University in Prague
Sample: 339 patients
Result: "An anonymous questionnaire sent to all patients attending the Prague Movement Disorder Center revealed that 25% of 339 respondents had taken cannabis and 45.9% of these described some form of benefit."
“Cannabinoids provide neuroprotection against 6-hydroxydopamine toxicity in vivo and in vitro: relevance to Parkinson's disease. "
Edited by: Departamento de Bioquímica y Biología Molecular III, Facultad de Medicina, Universidad Complutense, 28040-Madrid, Spain
Result: “Our results support the view of a potential neuroprotective action of cannabinoids against in vivo and in vitro 6-hydroxydopamine toxicity, which may be relevant for PD. Our data indicate that these neuroprotective effects could be due, among other things, to the antioxidant properties of some cannabinoids of plant origin, or exerted through the ability of cannabinoid agonists to modulate glial function, or a combination of both mechanisms.
