This EEG is from a child who was referred to you because of declining school performance. The teacher says the child daydreams a lot and seems to zone out during class.

Challenge: What's the diagnosis?

Absence makes the heart grow fonder. This is the presentation of absence seizures (also called petit mal or generalized nonconvulsive seizures) which consist of multiple brief staring episodes with behavioral arrest that can occur hundreds of times daily. The EEG shows the characteristic 3-hertz spike and slow wave pattern.
