Is sleep myoclonus more common in infants?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Sleep myoclonus is a condition marked by sudden, involuntary jerks or twitches that occur during sleep. It is most commonly observed in infants, where it is known as benign neonatal sleep myoclonus, and typically resolves on its own without treatment. In most cases, sleep myoclonus is harmless and does not indicate an underlying neurological problem.

However, persistent or frequent twitching in older children or adults may warrant closer attention, as it can occasionally be linked to sleep disorders, medication side effects, or other health conditions. If you or a loved one are experiencing unexplained movements during sleep, it's important to understand whether they're benign or a sign of something more. Take a free, instant, online symptom check to gain personalized insights and clarity on your next steps.

Explanation

Sleep myoclonus refers to sudden, brief muscle jerks that occur during sleep. According to the medical literature, such as the study by Hrastovec and colleagues, this condition is more frequently observed in infants. It is generally considered benign, meaning it is not harmful and does not lead to other health problems.

Common in Infants: Infants often experience sleep myoclonus, and it usually resolves on its own as they grow older.
Benign Nature: These muscle jerks are typically harmless and do not require treatment.

It is important for parents to know that while sleep myoclonus can be startling, it is usually a normal part of development and not a cause for concern.
