How long do episodes of sleep myoclonus typically last?

Sleep myoclonus refers to sudden, involuntary muscle jerks that happen during sleep. These episodes are typically brief, lasting from a few seconds to a couple of minutes.

Key Points:

• Duration: Episodes generally last a few seconds to a couple of minutes.
• Occurrence: They mainly occur during sleep and are considered normal.
• Age Group: This condition is often seen in newborns and infants.

According to the studies, benign neonatal sleep myoclonus is common in newborns and is not harmful. It is important to note that these episodes are not related to seizures or other neurological disorders. As children grow, these movements usually decrease and often disappear over time.
