Annual incidence is estimated at 0.7–4.6/100,000 in the general population, and up to 6–8/100,000 in children aged 0–15 years. Associated with a variety of generalized epilepsy syndromes. Age of onset varies depending on the coinciding syndrome, generally in the first two decades.
Synopsis of Neurology, Psychiatry, and Related Systemic Disorders
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.
