Using CBD to Treat Parkinson’s Disease Symptoms
The benefits and research around CBD are still emerging
With the legalization of medical marijuana, many states are approving the use of it in a non-traditional way to treat the symptoms of certain conditions, including Parkinson’s disease.
Marijuana has two major components to it—tetrahydrocannabinol (THC) and cannabidiol (CBD). Both may help with nausea and muscle pain or spasms, but unlike THC, CBD doesn’t give you the “high” feeling marijuana is most commonly known for.
This makes it an enticing, natural way for many to help treat their Parkinson’s disease symptoms. What’s more, is that because CBD is a natural compound from the Cannabis sativa plant, using it may also leave you side effect-free, unlike many prescription medications.
The body of research on using CBD for Parkinson’s disease symptoms is rapidly growing, as Parkinson’s disease affects 1% of the population over 60 years old.1 Parkinson’s disease is a neurological condition, affecting the nervous system. Parts of the brain that produce dopamine, which is responsible for sending messages to the body in order to direct movement, become damaged or die. This results in tremors, muscle stiffness, the inability to use facial expressions, and trouble balancing.
In connection with Parkinson’s disease as well as other movement-related disorders, CBD may help improve motor skills. In one study published in Frontiers in Pharmacology CBD was shown to have a more preventative role in delaying abnormal movement symptoms in animal models of Parkinson’s.2
Since Parkinson’s disease can take some time to properly diagnose when the symptoms are already prevalent, using CBD once diagnosed may not offer much benefit. With early detection combined with the use of CBD together the possibility of reducing movement-related symptoms increases.
Those dealing with Parkinson’s disease may also have trouble sleeping due to REM sleep behavior disorder (RBD), a condition in which patients ‘act out’ their dreams while asleep. A study published in the Journal of Clinical Pharmacy and Therapeutics found that four patients with Parkinson’s disease who also suffered from RBD had a decrease of RBD symptoms during sleep with the use of CBD.3
In some cases, people suffering from Parkinson’s disease may also have symptoms of psychosis, ranging in hallucinations to vivid dreams and illusions. Research has found that CBD may be able to help. In research out of University of São Paulo in Brazil, patients were given a dose of CBD starting out at 150 milligrams (mg) per day in addition to their current treatment plan of therapy for four weeks. The use of CBD showed no adverse effects, no impact on worsening motor function, and a decrease in their reported psychosis symptoms, meaning that not only can it help with the physical setbacks of Parkinson’s disease, it can also play a part in the cognitive challenges as well.4
More research out of Brazil suggests CBD can improve the overall quality of life of those with Parkinson’s disease. In a sample of 21 patients, those who were treated with 75 mg to 300 mg of CBD per day reported a significant increase in quality of life, though no significant differences were noted in motor and general symptoms or neuroprotective effects.5 This goes to show how much results can vary when it comes to the effects of CBD, requiring larger studies to be done in order to get more definitive answers to this treatment option.
Uses and Safety
Parkinson’s disease can impact cognitive function and memory, particularly in those whose symptoms progress to Parkinson’s disease dementia. Because of this, medical marijuana with both THC and CBD may not be recommended, as it can impair thinking and brain function even more so. CBD by itself may be a safer route.
CBD has been discovered as an effective way to help treat Parkinson’s disease symptoms because it interacts with two cannabinoid receptors in the body found on certain cells called CB1 and CB2. By interacting with one or both of these receptors, CBD may delay tremor development as well as have protective neurological benefits. But as seen with the above studies, there is no uniform approach or conclusion on this treatment method. This means that patients may react differently to using CBD, some having tremendous success while others seeing little difference.
If you’re interested in trying CBD for Parkinson’s disease, talk to your doctor about it. They will be able to point you to the latest research and provide recommendations on how much you should take. They will also be able to monitor your progress with the rest of your care team in order to come to a conclusion if this is the right treatment plan for you.
