Myoclonus is a fast, involuntary muscle jerk that occurs in either singular muscles or a group of muscles. It is a symptom and not a diagnosis of a disease. Myoclonic twitches or jerks are the results of sudden muscle contractions that are called myoclonus. If the muscle twitch is caused by muscle relaxation, it is referred to as negative myoclonus. Myoclonic jerks may occur on an individual basis or in a sequence. Depending on the severity, myoclonic jerks sometime occur many times per minute or they can also occur infrequently.

Myoclonus can be widespread throughout your body and involve persistent contractions in a group of muscles. Some healthy people experience myoclonus with no other complications, while others experience more severe cases of myoclonus that limit a person’s ability to eat, talk or walk. If the case is severe enough, it can indicate a disorder in the brain or the nerves.


An infection, a head or spinal cord injury, a stroke, brain tumors, kidney or liver failure, lipid storage disease, chemical or drug poisoning, or other disorders may be the cause behind the development of myoclonus. However, myoclonus can also occur by itself, but it is usually associated with multiple nervous system disorders and diseases including Parkinson’s, Alzheimer’s, Creutzfeldt-Jakob and epilepsy.

Types of Myoclonus

There are many different varieties of myoclonus that are classified based on the causes, effects, and responses to therapy. Varieties include action myoclonus, cortical reflex myoclonus, essential myoclonus, palatal myoclonus, progressive myoclonus epilepsy, reticular reflex myoclonus, stimulus-sensitive myoclonus, and sleep myoclonus.

Medical Marijuana for Myoclonus

Research shows that medical marijuana works as a muscle relaxant and an anticonvulsant, both of which are caused by myoclonus. Many epilepsy symptoms also occur with myoclonus. Since medical marijuana is effective in treating epilepsy in many people, it may also be effective in treating myoclonus. Cannabidiol is shown to minimize seizure activity.

Another benefit that medical marijuana has is its anti-anxiety and anti-depressant effects, which are two common feelings with myoclonus. Not knowing when another myoclonus episode will occur can cause anxiety, so medical marijuana can help relieve this feeling of anxiousness.
