Parkinson’s Illness (PD) is a chronic neurodegenerative disorder that impacts more than 100,000 Canadians these days, with about six,600 new instances getting reported every year. The hallmark symptoms of the illness are tremors, rigidity, bradykinesia and postural instability. In the brain, the illness is characterized by the degradation of a distinct sort of cell, the nigrostriatal dopamine neurones, which causes in a deficiency in dopamine and leads to the motor, cognitive and neuropsychological impairments connected with the illness.
Existing medicines aim to restore the balance in dopamine levels to deliver relief of motor symptoms, but they do not address the trigger or the progression of the illness. For several individuals, these medicines make side effects such as dyskinesia (abnormal involuntary movements) which demands to be controlled with additional medication.
Healthcare cannabis and some of the active molecules derived from the Cannabis sativa plant are getting investigated as possible therapies for PD each for the alleviation of motor and non-motor symptoms and for the possible to slow the progression of the illness. In this report we highlight some of the important findings in the clinical and experimental study of health-related marijuana in PD, that was reported in a scientific report final year.

Cannabis includes more than 500 elements and is 1 of the most studied plants chemically. Though several of the plants elements can be identified in other species, a group of chemical substances known as the phytocannabinoid compounds are special. Of the phytocannabinoids, the most deeply studied and most abundant are delta-9Tetrahydrocannabinol (delta-9 THC) and cannabidiol (CBD). Delta-9 THC is a psychoactive and is the compound that is mainly accountable for the ´high’ of marijuana, it is also a potent analgesic and muscle relaxant. CBD performs differently, it is not psychoactive, rather it appears to counteract delta-9 THC activity and minimize side effects of anxiousness, tachycardia and hunger. At the cellular level, we know that the effects of phytocannabinoids are brought about by their interactions with the family members of cannabinoid receptors and that these receptors orchestrate a wide quantity of cellular processes all through the physique. Relevant to PD, we now know that elements of the cannabinoid technique (the collective name for the endogenous cannabinoid compounds and their receptors) are abundant in the brain and are involved in regulating dopamine activity and motor functions. In PD the standard pathways of the endocannabinoid technique are disrupted. Offered the similarities in between human (endogenous) and plant derived cannabinoids, it comes as no surprise that the phytocannabinoids have been proposed as possible therapies thanks to their potential to mediate the pathways involved in PD.
Making use of Cannabis for the therapy of the motor symptoms of PD is not new. In truth, the initially reported case of effective therapy of PD individuals with a Cannabis tincture was reported in 1888 by Dr William Gowers in his book ‘A Manual of Illnesses of the Nervous System’. In the final decade a quantity of clinical research have evaluated the effectiveness of health-related marijuana and cannabinoids for the therapy of PD motor symptoms. For instance, in 2004, a clinical study carried out in 339 individuals with PD showed that 46% of individuals that applied marijuana knowledgeable improvements in common PD associated symptoms and in distinct symptoms such as resting tremor (31%), rigidity (38%), decreased bradykinesia (45%) and alleviated dyskinesia (14%). Symptomatic improvement was straight associated to the concentration of THC metabolites in the urine. These findings have been observed in further research, exactly where improvements in sleep and reduction in discomfort have been also recorded. Adhere to this hyperlink to study the study reports.
Even though these research focussed on motor symptoms, study has shown that health-related marijuana can enhance the good quality of life of PD individuals by means of the relief of non-motor symptoms such as:
- Discomfort, the analgesic properties of cannabinoids are clinically nicely documented
- Depression, moderate use of cannabis can deliver relief from depression
- Sleep issues, the majority of PD individuals endure from sleep issues and this negatively impacts their good quality of life. Sleep troubles can be brought on by a number of aspects such as neurodegeneration and medication side effects.
Lastly, study in-vitro and in mouse models of PD are examining the potential of cannabinoids to slow illness progression. Cannabinoids seem to have neuroprotective effects due to anti-inflammatory and anti-oxidative activity and their potential to suppress exitotoxicity (a approach that causes nerve cell harm). As we realize a lot more about the intricate mechanics of the endocannabinoid technique in humans and how these are disrupted in PD, phytocannabinoids could give substantially necessary new therapeutic alternatives for individuals.
