Cannabinoid receptors run throughout our body as part of the endocannabinoid system regulating physiological operations including hunger, pain sensitivity, temperament, and memory. These natural receptors are affected in patients with PD. As analyses continue, CDB is demonstrating relief for tremors, psychosis, and problems sleeping. CBD may also reduce depression and anxiety, and relieve pain. A study at the Colorado School of Medicine has demonstrated relief of issues including tremors and difficulty sleeping. CBD studies are also showing it as effective in treating the psychosis that comes with PDD (Parkinson’s disease dementia). So far, patients are tolerant of low doses of CBD oil and report positive effects.
