Medical Marijuana and Myoclonus

marijuana and myoclonus

While not a disease on its own, myoclonus is a symptom that can cause limitations on normal activities. The sudden, involuntary muscle jerking is often minor but can become severe.

Prescription medications can help control the jerking in many patients, but some prefer a more natural approach to treatment or don’t find relief from traditional options. Exploring the possibility of using medical marijuana for myoclonus may help you enjoy a more normal life without the harmful side effects of prescription drugs.

What Is Myoclonus?

Myoclonus describes a range of quick, sudden and involuntary muscle jerks that can happen in a single muscle or a group of muscles. Scientists believe the symptom often occurs due to a central nervous system disturbance. You cannot stop or control the jerks, and it sometimes increases as you try to move.

The severity of muscle jerking can range from a twitch to an intense contraction that feels like a shock. Positive myoclonus refers to a sudden muscle contraction, while negative myoclonus is a muscle relaxation.

The frequency of myoclonus also varies. You might experience one twitch in isolation or a series of muscle jerks, which may occur with or without a distinct pattern. You may also have one or two twitches within an extended period, or you may experience multiple twitches within a short time span. The muscle jerking can constantly continue in some people.

Some cases of mild myoclonus happen in healthy individuals. Hiccups are an example of myoclonus that anyone can experience, even when healthy. The jerking or “sleep starts” that people sometimes experience shortly after falling asleep are another example. These myoclonus forms do not indicate a problem or lead to any lasting effects or complications.

In severe cases, the contractions increase in intensity in a persistent, widespread manner. Some people may notice the twitching starts in one area and spreads to other muscle groups. In some cases, the jerking is so severe that you have difficulty talking, walking and eating.

Myoclonus can occur without any underlying cause. However, there is typically an underlying condition or external force that initiates the muscle jerking. Some potential situations that cause a myoclonus response include:

  • Infection
  • Head or spinal cord injury
  • Stroke
  • Brain tumor
  • Kidney failure
  • Liver failure
  • Lipid storage disease
  • Poisoning from drugs or chemicals
  • Prolonged oxygen deprivation in the brain

Myoclonus is also a symptom of many nervous system disorders and other conditions. Some of these disorders include:

Severe cases of myoclonus can decrease your quality of life by interfering with everyday activities. Because the episodes are unpredictable, patients sometimes suffer from anxiety or avoid certain situations to prevent having an event in public.

Types of Myoclonus

The defining characteristic of myoclonus is the muscle jerking. However, there are different kinds of muscle jerks, which affect how the symptom presents itself. Identifying the type of myoclonus and its underlying cause is an essential step in creating an effective treatment plan.

Some key types of myoclonus include:

  • Physiological: This form describes hiccups, sleep starts, spasms and other kinds of twitching in otherwise healthy individuals caused by exercise or anxiety. This form is harmless and doesn’t interfere with activities.
  • Essential: People with essential myoclonus experience twitching without an underlying condition. It happens on its own for unknown reasons. Some people may inherit essential myoclonus. This form often stays stable without increasing in severity but can be difficult to treat since it has no underlying medical condition.
  • Secondary: These types of muscle jerks have a known underlying cause or identified medical condition.
  • Cortical reflex: These jerks affect only a few muscles and may increase in severity when you try to move in a certain way. This form is often considered a type of epilepsy that originates in the cerebral cortex.
  • Palatal:Twitching occurs in the soft palate, or on the sides of the roof of your mouth. The twitching typically happens in rapid succession, with as many as 150 contractions each minute. You may also experience myoclonus in other areas, such as the tongue, face or throat. Palatal myoclonus can cause a clicking sound, discomfort or severe pain.

  • Reticular reflex: Thought of as a generalized type of epilepsy originating in the brain stem, this form affects the entire body. Sometimes the jerking occurs in just one part of the body such as the legs. Voluntary movements and external stimuli can trigger an episode.
  • Stimulus-sensitive: In this type of myoclonus, the jerking happens in response to an external stimuli, such as noise, movement and light.
  • Sleep: As the name suggests, this type of myoclonus happens when you first start to fall asleep. This form sometimes accompanies other sleep-related disorders, such as restless legs syndrome (RLS).
  • Action: The most debilitating form, action myoclonus, worsens when you make voluntary movements, particularly precise, coordinated movements. It can affect the arms, legs and face and often occurs after brain damage that resulted from a lack of blood flow and oxygen.

Physicians use a variety of tests to diagnose myoclonus. The diagnosis typically starts with an overview of your medical history and then a physical exam. The tests performed help rule out other causes, as well as potentially diagnose the underlying condition causing myoclonus.

Some possible tests include:

  • EEG: An electroencephalography records your brain’s electrical activity to find the origin of myoclonus.
  • EMG: Another test option is an electromyography, which evaluates electrical discharges from muscles to determine the cause and pattern of myoclonus.
  • MRI: Physicians may use MRIs to look for tumors or structural problems that could be causing the twitching.
  • Lab tests: Doctors may check for certain diseases or other factors that may cause myoclonus. Tests may look for metabolic disorders, as well as autoimmune diseases, diabetes, kidney disease, liver disease, drugs or toxins.

Finding what is causing your myoclonus helps you and your physician decide what treatments are available and viable for your type of myoclonus.

Traditional Treatment Options for Myoclonus

Traditional treatments may focus on treating the underlying cause of myoclonus and controlling your muscle jerks. In cases resulting from a treatable condition, it’s possible to eliminate the myoclonus by correcting the underlying condition. In other cases, the condition is either unknown or incurable. In these situations, doctor focus on controlling the jerking in the muscles.

Some potential treatments include:

  • Tranquilizers: Clonazepam is a common drug for myoclonus. The doctor may start at a low dosage and gradually increase it to reach maximum effectiveness while minimizing the side effects. Common side effects include drowsiness and loss of coordination. You may also develop a tolerance for the drug over time, making it less effective.
  • Anticonvulsants: Another prescription drug option is anticonvulsants. Typically used to treat epilepsy, this drug can also reduce the jerking that occurs with myoclonus. Anticonvulsants include levetiracetam, valproic acid and primidone. Levetiracetam can cause fatigue and dizziness, while valproic acid may cause nausea. Primidone can lead to nausea and sedation.
  • Botox: Some cases of myoclonus respond well to Botox injections. This option is best for when the condition affects a single area.
  • Surgery: When the underlying cause is a tumor or lesion, surgery is a common option for treating myoclonus.

Because myoclonus has different causes, finding the correct treatment often takes time. Patients may take several different prescription drugs to keep their symptoms in check, which can cause multiple side effects that can affect your quality of life.

Why Medical Cannabis for Myoclonus Is Effective

Medical marijuana works as a muscle relaxant and an anticonvulsant, which can help minimize or control the jerking muscle action caused by myoclonus. Many of the same prescription drugs used to treat epilepsy are also used to treat myoclonus, even if epilepsy isn’t the underlying cause.

Since medical cannabis is effective in treating epilepsy in many people, it may also be effective in treating your myoclonus. Studies and anecdotal evidence show that marijuana has a positive effect on muscle spasms as well.

Another potential benefit of marijuana is its anti-anxiety and anti-depressant effect. Not knowing when a myoclonus episode will occur causes anxiety, especially in social situations. Marijuana creates a relaxing feeling that can help relieve that anxiousness.

Specific research regarding medical cannabis and myoclonus is not prevalent. Several studies, however, point to medical weed’s use for anticonvulsant and antiseizure effects. Cannabidiol (CBD), in particular, minimizes seizure activity.

CBD is a cannabinoid that occurs naturally in marijuana. When ingested, it works with the body’s natural endocannabinoid system. CBD, for example, activates CB1 receptors in the body. When activated, that receptor slows neurotransmissions and minimizes neuron excitability, which may help dampen myoclonus.

Marijuana and Myoclonus Treatment

When using medical cannabis for myoclonus, it’s important to work with an experienced medical marijuana doctor. Your doctor will evaluate your medical history and specific myoclonus symptoms to create a treatment plan suited to your case.

Part of the process is selecting a strain of medical marijuana to use. A strain high in CBD may have the greatest impact on your symptoms. CBD is a non-psychoactive chemical in marijuana, which means it doesn’t cause a “high.” Many strains of medical marijuana contain small amounts of tetrahydrocannabinol (THC) to minimize the cerebral effect of medical cannabis.

When evaluating medical marijuana strains, you’ll notice they are described as Indica or sativa, which are two different plant species. Hybrids combine elements of both.

A strain heavy on Indica tends to have higher levels of CBD. Indica strains have a more sedating effect, which can increase relaxation and sleepiness. The effects tend to work throughout the body. Indica strains work well when you want to relieve twitching and contractions from myoclonus at night so that you can ease the muscle twitching and fall asleep faster.

Sativa strains have higher levels of THC, which results in a greater sense of euphoria. The effects are more cerebral based and may give you an uplifting feeling. THC can be beneficial when you need a burst of energy and creativity while keeping your myoclonus contractions under control. Remember that sativa strains may increase muscle spasms in some people due to the stimulating properties of these strains. For this reason, it may be more beneficial to use Indica strains.

The way you consume the selected strain can also have an impact on how effective medical marijuana is in treating myoclonus. Consider the following methods:

  • Smoking: When you smoke your selected strain of medical marijuana, you feel the effects almost instantly. This instantaneousness can be beneficial if you’re experiencing a prolonged episode of twitching and want to slow or stop the muscle movement immediately. Instant relief may also help you resume normal activities.

The drawbacks of smoking medical marijuana pertain to the byproducts produced by the combustion of the plant. Smoking may potentially cause respiratory issues as well.

  • Vaporizing: Another way to stop muscle jerking immediately is through vaporizing medical weed. You use a machine that heats the marijuana to form the vapor, which happens at a lower temperature than smoking so that it doesn’t cause combustion. Because of this, vaporizing minimizes the byproducts.

Vaporizing offers almost immediate effects, which is beneficial during a myoclonus episode. You may start noticing reduced muscle spasms after only a few puffs from your vaporizer, which is a huge benefit when you’re experiencing ongoing twitching, especially when it interferes with your activities.

  • Edibles: Edibles high in CBD provide longer lasting relief than smoking and vaporizing, which means you can potentially enjoy a longer period without muscle twitching. You will have to wait a little longer to start experiencing relief, though. Edibles take anywhere from 30 minutes to a few hours to work.

  • Topical application: When myoclonus affects a particular area of your body, topical application is a useful option. Medical marijuana is available in lotions and similar products as well as transdermal patches. Both options are applied on the area where you’re experiencing the muscle twitching. Choose a topical product high in CBD for the best results.

You and your medical marijuana doctor will likely discuss the available forms of medical cannabis and which one would benefit you most, based on your case. Your state’s medical marijuana laws will also have a role, as some states do not allow the smoking of medical weed.

Side Effects of Marijuana for Myoclonus

While medical marijuana is a natural option for treating myoclonus, it still has some side effects that you should consider. When comparing the side effects of other treatment options, marijuana’s effects are relatively minor and short-lived.

Some of the effects you may feel with medical marijuana use include:

  • Euphoric feelings
  • Dry mouth
  • Red eyes
  • Increased appetite
  • Sleepiness

When comparing the side effects of medical cannabis to prescription drugs, it’s important to consider what you consider a negative. Some people don’t mind the side effects of medical marijuana or even find them useful. If you find it difficult to rest well, the drowsiness you feel from some strains can help you sleep better, for example.
