Laboratory Studies

If jitteriness or tetany remain in the differential diagnosis, screening for hypoglycemia and electrolyte disturbances is indicated.


Imaging Studies

Once benign neonatal sleep myoclonus (BNSM) is identified, no imaging studies are indicated. If epilepsy or seizures remain a concern, MRI is the study of choice in infants.


Other Tests

If seizures remain a consideration, performing EEG is appropriate. Prolonged EEG monitoring, during multiple sleep/wake cycles potentially allows for time-locked data collection during episodes, making this the optimal study for infants in whom diagnostic confusion remains.
