Abstract

We report on a male infant with benign neonatal sleep myoclonus (BNSM). At 12 days of age, he began to have frequent myoclonic jerks in the lower and/or upper extremities during sleep. Myoclonic jerks appeared bilaterally/synchronously and persisted for several minutes to 10 minutes. Both interictal and ictal EEG findings were normal. During follow-up, the patient did not take any medication, and his myoclonic jerks gradually decreased. They completely disappeared at 50 days of age. The patient's development was normal.<BR>BNSM is a benign disorder and myoclonic jerks generally disappear without medication. Early diagnosis is important to avoidunnecessary treatment. EEG-EMG recording is useful for diagnosis.
