What does absence seizure look like on EEG?
Typical absence seizures have generalized 3-Hz spike-and-wave complexes (see image below). EEG of a typical absence seizure with 3-Hz spike-and-wave discharges. The spike frequency is often faster at the onset, with a slight deceleration at the end.
Which antiseizure agents is used to treat absence seizures?
If absence seizures are present along with other seizure types (eg, generalized tonic-clonic seizures, myoclonic seizures), the choices are valproic acid, lamotrigine, or topiramate. Do not use carbamazepine, gabapentin or tiagabine, because these drugs may exacerbate absence seizures.
Can a child have a seizure and not know it?

What triggers silent seizures?
Affecting about two of every 1,000 people, absence seizures (formerly called ”petit mal” seizures) are caused by abnormal and intense electrical activity in the brain. Normally, the brain’s nerve cells (neurons) communicate with one another by firing tiny electric signals.
