Childhood absence epilepsy; Juvenile absence epilepsy; Petit mal epilepsy
Childhood and juvenile absence epilepsy are forms of idiopathic (genetic) generalized epilepsy that are characterized by seizures that involve sudden arrest in activity, awareness, and responsiveness, and may include some mild motor features. Typical absence seizures usually last less than 20 s and end as abruptly as they start. Patients have no recollection of the event and often return immediately to their previous activity with little or no postictal alterations in functioning. Generalized 3 Hz spike-and-wave discharges on EEG are required for the diagnosis and are strongly correlated with the clinical events.
Childhood absence epilepsy (CAE)
Juvenile absence epilepsy (JAE)
The incidence of CAE is estimated at 6–8% per 100,000 in children younger than 15 years, and the estimated prevalence is 10–12% in children younger than 16 years with epilepsy. The incidence...
