The legalization of CBD through instruments such as the Agriculture Improvement Act of 2018 has resulted in massive research on the substance’s medical opportunities. The cannabidiol’s brain and nervous system benefits have been in the limelight recently.

This is particularly true for neurological disorders. Among others, CBD or Cannabidiol has been found to have the potential to treat conditions such as Parkinson’s disease. Although research is still ongoing, preliminary results have shown that CBD might be helpful with this progressive disorder.

The cannabidiol’s medicinal abilities are mainly non-psychoactive, unlike its counterpart delta-9-tetrahydrocannabinol. Therefore, it does not alter the cognitive functions of the brain.

What is Parkinson’s Disease?

It is a progressive movement disorder that affects the nervous system. Parkinson’s disease begins gradually, usually starting with a hardly noticeable tremor on the one hand.

The condition worsens over time as it progresses. Although the disease cannot be cured, treatments are focused on improving the quality of life.


The symptoms of Parkinson’s disease vary from one person to another. It is crucial to note that early signs can be mild and unnoticed. They usually begin on one side of the body and then progress to another. The most common symptoms of Parkison’s disease are discussed below.


People suffering from Parkison’s disease usually have included a tremor or shaking that occurs when the hand is at rest.

Slowed Movement

As the disease progresses, it may result in slowed movement. One’s step may become shorter and regular tasks such as getting out of your chair may prove difficult. Therefore, simple tasks may become time-consuming.

Impaired Posture and Balance

Parkinson’s disease also causes one’s posture to become stooped. Patients may also experience balance problems.

Stiff Muscles

The body may experience rigid muscles. These may be painful and limit one’s range of motion.

Loss of Reflex Actions

Parkinson’s disease also decreases one’s ability to perform automatic movements such as smiling, blinking, and swinging your arms when walking.

Impaired Speech and Writing

Patients may find difficulties in speaking difficulties. Their speech may be more monotone rather than the usual reflections. People who have Parkinson’s disease may also find writing to be a difficult task. Their writing may appear small.

Causes of Parkinson’s disease

Research concerning the causes of Parkinson’s disease is still ongoing. However, several reasons have been linked to the disease. These are discussed below.

Low Dopamine Levels

The symptoms of Parkinson’s disease are majorly a result of reduced or falling dopamine, a neurotransmitter in the nervous system. This occurs due to the death of cells that produce the neurotransmitter in the brain.

Dopamine serves to send messages to a part of the brain responsible for controlling coordination and movement. As the neurotransmitter levels continue to drop, the symptoms become more severe.

Low Norepinephrine Levels

Parkinson’s disease may also be attributed to the damage of nerve endings that produce norepinephrine. Another neurotransmitter helps in blood circulation and other reflex body actions. The reduction in norepinephrine results in rigidity and postural instability.

Lewy Bodies

The condition is also caused by having clumps of protein, better known as Lewy bodies or alpha-synuclein, in the brain. Lewy bodies result in the loss of nerve cells, affecting movement, mood, and cognitive abilities.

Genetic Factors

Genetic factors have also been found to be linked with Parkinson’s disease.
Autoimmune factors Medical studies also suggest a link between the disease and autoimmune conditions such as rheumatoid arthritis.

CBD for Parkinson’s Disease

When it comes to CBD and Parkinson’s disease, the cannabinoid has not been used in long-term people with the disease. Studies into its benefits in as much as Parkinson’s disease is concerned is only a few decades old.

As a result, the research is still limited as small efforts are made. There is a need for larger-scale efforts if scientists confirm the results. However, preliminary findings suggest that CBD may have beneficial effects on symptoms such as pain, tremors, sleeping disorders, and psychosis.


According to research conducted on people with Parkinson’s disease, CBD was found to help reduce pain. This is very good news considering that pain and inflammation are some of the two factors that reduce the quality of life in people with the disease.


Some mainstream treatments for Parkinson’s disease result in medicine-related tremors or uncontrolled muscle movements. Attempting to treat it with the medicine won’t make it better. It can make it worse. Medical studies have found CBD to help ease these muscle movements.


Parkinson’s disease can cause psychosis complications. The result is hallucinations, delusions, and delirium. This is especially true for people at the later stages of the stages. Over half of Parkinson’s disease patients experience these symptoms.

Of course, there are some medical treatments for Parkinson’s psychosis. However, research has also found CBD to be a useful remedy. The cannabinoid can reduce the severity of the symptoms with minimal side effects.


Sleeping disorders are a common occurrence in people with Parkinson’s disease. They may experience vivid dreams or nightmares, as well as movements. Medical investigations have found CBD to be useful in improving the quality of sleep in patients.

Can I Use CBD to Prevent Parkinson’s?

Currently, there are no CBD-based medications approved by the Food and Drug Administration for Parkinson’s disease. However, efforts are underway. Scientific researchers from the University of Colorado are looking into the benefits of Epidiolex, a drug approved by the FDA to treat two rare forms of epilepsy, for Parkinson’s disease-related tremors.

There is a need for more extensive research efforts if CBD is prescribed as a treatment for the condition. However, individuals can use cannabidiol as a preventative measure while researchers carry on their studies.

CBD and Endocannabinoid System

The endocannabinoid system, commonly abbreviated ECS, is a complex cell-signaling system discovered by researchers in the late 20th century. It involves three main components, namely endocannabinoids, receptors, and enzymes.

The endocannabinoid system is responsible for regulating key bodily functions such as mood, appetite, memory, sleep, etc. According to medical research, some medical conditions such as pain, anxiety, depression, insomnia, and so on are caused by the imbalance of endocannabinoids in the ECS.

As a result, they can be addressed by introducing phytocannabinoids such as CBD to restore the much-needed balance. This is the mechanism through which CBD can treat or manage many medical conditions.


Undoubtedly, CBD poses a promising remedy for individuals who have Parkinson’s disease. The substance might help ease the symptom of the neurological condition and help reduce the side effects of the most common treatments as well.

However, it is paramount to highlight that studies done so far are still minimal, and there is a need for more in-depth studies before physicians and the FDA gives the nod. Some medical practitioners are embracing CBD as a complementary treatment.

Therefore, it is recommended that you visit your doctor and discuss how you can benefit from the cannabinoid to find relief from Parkinson’s disease.
