Nonconvulsive generalized seizure type characterized by brief episodes of abrupt loss of consciousness, lasting 10–20 seconds, which may occur on a frequent, recurrent basis. Associated with subtle freezing or oral or manual automatisms. Of shorter duration than complex partial seizures, and a postictal period is not present.
Events can be mistaken for daydreaming,
which may contribute to delay in diagnosis. Typical absence seizures have a 3-Hz generalized spike and wave pattern on the EEG, often provoked by hyperventilation.
