Answer

Electroencephalography plays a vital role in properly identifying and differentiating neonatal seizures from nonepileptic events. [11, 12] Video EEG monitoring may be helpful when infrequent neonatal seizures persist. [13] (See the images below.)

Onset of neonatal seizure demonstrating a focal on Onset of neonatal seizure demonstrating a focal onset in the right frontal (FP4) region. At this point, the child had head and eye deviation to the left.
Twenty seconds into a seizure that had focal onset Twenty seconds into a seizure that had focal onset in the right frontal (FP4) region, the seizure shows a rhythmic buildup of activity in the right frontocentral region.
This seizure had focal onset in the right frontal 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.
