Do Marijuana and CBD Help Ataxia? [Explained]

The term ataxia describes a group of debilitating movement disorders. There are many different types of ataxia, and they can all affect essential functions, including balance, coordination, and speech. Unfortunately, there is currently no cure.

The lack of effective ataxia treatments has led some patients to wonder whether medical marijuana or CBD oil could help. In this article, we explain all about using cannabis for ataxia. Read on to learn more.

What Is Ataxia?

Ataxia is not one condition but a group of conditions that affect the cerebellum region of the brain. The cerebellum is responsible for controlling balance, limb coordination, speech, and eye movement. Ataxia can also affect other parts of the nervous system, including the spinal cord and peripheral nerves.

Ataxia is not one condition but a group of conditions that affect the cerebellum region of the brain.

When cell damage occurs in these structures, it can significantly impact a person’s life. Everyday activities can become challenging, and in some cases, life expectancy may decrease.

However, there are several different types of ataxia, and each one produces slightly different effects.

Types of Ataxia

It is possible to categorize ataxia into three main groups:

Acquired ataxia:

This type of ataxia occurs as a result of brain trauma, alcohol misuse, nutritional deficiencies, or other conditions, including multiple sclerosis (MS), stroke, or brain tumors.

Hereditary ataxia:

Hereditary ataxia occurs due to a genetic mutation. Common types of hereditary ataxia include Friedreich’s ataxia, ataxia-telangiectasia, and spinocerebellar ataxia (SCA).

Idiopathic late-onset cerebellar ataxia (ILOCA):

Progressive brain damage occurs over time for unknown reasons.

Ataxia Symptoms

The symptoms of ataxia can vary depending on the type. However, the most common ataxia symptoms include difficulty with:


  • Balance and walking
  • Speaking
  • Swallowing
  • Writing
  • Eating
  • Eye movement

Some other symptoms that may coexist with ataxia (depending on the specific type) include:

  • Muscle stiffness and cramps
  • Curvature of the spine
  • Incontinence
  • Heart problems
  • Reduced immunity
  • Diabetes
  • Peripheral neuropathy
  • Fatigue
  • Depression

In some cases, these symptoms can remain stable for many years. However, in most patients, they become progressively worse over time.

Traditional Ataxia Treatments (Not Marijuana or CBD)

There is no cure for ataxia, and, therefore, treatments aim to support patients in their everyday lives. Doctors may prescribe medication to relieve individual symptoms, such as muscle stiffness or bladder problems.

Some other therapies which may help include:

  • Speech and language therapy
  • Physical therapy
  • Occupational therapy

With so few options available, more and more people are asking whether cannabis and CBD oil could help ataxia. Unfortunately, there is not a vast amount of information available on the subject at present. Here is what we know so far.

Does Cannabis Help Ataxia?

At the time of writing, there are no completed clinical trials on cannabis for ataxia. However, there are case reports that suggest it could provide some benefits.


For example, one patient experienced improvements in symptoms after smoking marijuana. The authors of this case study concluded that cannabis might have “powerful benefits” for ataxia and spasticity.

Another report looked at the effects of oral THC on eight patients with MS, tremor, and ataxia. Two of the patients experienced improved motor coordination after treatment.

Thus, it appears that cannabis could potentially help ataxia.

Ataxia and the Endocannabinoid System

Researchers have studied the brains of mice and conducted post-mortem investigations on patients with SCA. The results show that ataxia is associated with an altered endocannabinoid system in the cerebellum.

Cannabis contains a variety of active chemicals, including cannabinoids like THC and CBD. These molecules interact with receptors in the ECS to produce powerful effects on the body and brain.

However, THC and CBD affect the ECS in very different ways. So, is one more effective than the other for ataxia?

THC or CBD for Ataxia?

The best-studied cannabinoids in cannabis are THC and CBD. THC is responsible for creating the marijuana high. It also has a range of medical uses, including relieving pain, stiffness, nausea, and stimulating the appetite.

On the other hand, CBD lacks intoxicating effects but possesses many medicinal benefits of its own. It is known to have potent anti-inflammatory, antioxidant, and neuroprotective properties.

Therefore, it may be useful in the treatment of several neurological diseases, including epilepsy, Parkinson’s disease, and MS.

The difference in these effects is due to the way the two compounds interact with the ECS. THC binds directly to cannabinoid receptors, while CBD affects them indirectly by increasing levels of our natural endocannabinoids.

THC binds directly to cannabinoid receptors, while CBD affects them indirectly.

CBD also acts as a negative allosteric modulator at ECS receptors. What this means is that it prevents THC from binding with these receptors as effectively and curbs its adverse side effects. This information is especially relevant regarding the use of THC and CBD for ataxia.

Research published by The Journal of Physiology in 2016 suggests that activating cannabinoid receptors can reduce motor coordination. This is one reason why some people become less coordinated after using marijuana. However, compounds like CBD can counteract overstimulation and potentially reverse these effects.

Therefore, a combination of THC and CBD may work best for ataxia. The THC may act to stimulate the receptors enough to relieve symptoms, while CBD may decrease the likelihood of adverse reactions. But this is just conjecture—there isn’t enough scientific evidence that directly supports this.

Those who live in a state with a medical marijuana program should have access to various cannabis strains with a 1:1 THC to CBD ratio. Otherwise, a doctor may prescribe a drug called Sativex. This medicine contains both THC and CBD and is licensed as a treatment for MS.

How to Use CBD Oil for Ataxia

Those who do not have access to medical marijuana or Sativex may still be able to purchase hemp-derived CBD oil. These products come from industrial hemp and contain less than 0.3% THC. Therefore, they are available in the majority of states.

Although they only have traces of THC, these oils contain many other beneficial cannabinoids, as well as terpenes and flavonoids. However, to benefit from the full range, one needs to purchase a full-spectrum oil rather than an isolate.

When purchasing CBD oil for ataxia, it is also essential to choose a reliable brand. The market is not well-regulated, and a lot of companies are selling substandard products. As a bare minimum, look for a manufacturer that provides third-party lab reports for all of its products.

Regarding how to use CBD oil for ataxia, there are numerous options. The most traditional CBD products are oils or tinctures that patients administer under the tongue. However, this method can be fiddly, especially for people with coordination problems.

Therefore, people with ataxia may prefer other ways of taking CBD, such as capsules, edibles, or vape products. Each of these has pros and cons.

For example, capsules and edibles have to pass through the digestive system. This means that some of their CBD gets lost along the way. However, many consumers say the effects of these products last longer than other consumption methods.

CBD vape products act much more quickly as they do not undergo digestion. However, the effects may be shorter-lived. Furthermore, the long-term health effects of vaping are unknown, and not everyone enjoys this method.

Do Marijuana and CBD Help Ataxia? Final Thoughts

There is limited evidence that cannabis and CBD help ataxia, but some patients may find them useful. By interacting with the endocannabinoid system, these natural medicines could relieve some symptoms, like muscle stiffness and movement disorders. However, research is still in its infancy.

It is essential to consult a physician before using either CBD oil or marijuana for ataxia. It is also important to conduct in-depth research before making a purchase and ensuring you choose the most appropriate product for you.
