Absence Epilepsy

Absence Epilepsy

Absence Epilepsy/seizures are one of several kinds of seizures. These seizures are sometimes referred to as petit mal seizures (from the French for "little illness", a term dating from the late 18th century). Absence seizures are brief (usually less than 20 seconds), generalized epileptic seizures of sudden onset and termination. They have two essential components: clinically, the impairment of consciousness (absence) Electroencephalography (EEG) shows generalized spike-and-slow wave discharges. Absence seizures are broadly divided into typical and atypical types. Typical absence seizures usually occur in the context of idiopathic generalised epilepsies and EEG shows fast >2.5 Hz generalised spike-wave discharges. The prefix “typical” is to differentiate them from atypical absences rather than to characterise them as "classical" or characteristic of any particular syndrome.
