Research shows that cannabinoids are neuroprotective in acute and chronic neurodegeneration and can delay or even stop progressive degeneration of the brain dopaminergic system, a process that cannot be currently prevented in any other way. While the Parkinson’s medications available today only treat motor symptoms, studies show cannabis effectively addresses non-motor symptoms as well.
In a retrospective cohort study that tested 47 Parkinson’s disease (PD) patients and the effect of cannabis on them, medical cannabis was found to improve symptoms of PD in the initial stages of treatment and did not cause major adverse effects.
Pain reduction was reported by 81.4% of subjects, 75% of subjects reported an improvement in mood, and most patients reported an improvement in sleep quality.
