Cranial MRI is the most sensitive imaging study for determining the etiology of neonatal seizures, particularly when electrolyte imbalance has been excluded as the seizures’ cause. [18] A major disadvantage is that MRI cannot be performed quickly and, in an unstable infant, it is best deferred until the acute clinical situation resolves.

This seizure had focal onset in the right frontal (FP4) region and subsequent buildup of activity in the right frontocentral region. As the seizure evolves, the electroencephalogram shows diffuse involvement of both cerebral hemispheres.
