Multiple seizure types: i) GTCS ii) Atypical absence iii) Atonic seizure Etiology = multifactorial EEG = <2.5 Hz spike & slow wave D.O.C =Na valproate * Is associated with CNS disease or dysfunction from a variety of causes, including de novo mutations, developing abnormalities, perinatal hypoxia/ ischemia. * Has poor prognosis due to underlying CNS disease.
Single seizures type
Occurs in adults
Good prognosis with adequate control
EEG showing less than 2.5 Hz spike and wave discharge
