Contemporary drug therapy fails to control epileptic seizures in some 30% of patients, resulting in the need to employ other measures when they appear practicable. A good deal of potentially relevant statistical detail is available regarding the outcomes of the available antiepileptic therapies, but its interpretation[…][oadoi.org]

Tonic status epilepticus (TSE) in patients with idiopathic generalized epilepsy (IGE) is not well recognized. The objective of this study is to report episodes of TSE in patients with IGE. We retrospectively reviewed the clinical and EEG evaluation of three IGE patients who presented TSE. The three patients had mainly[…][ncbi.nlm.nih.gov]

Abstract The EEG of 38 patients suffering from primary generalized myoclonic astatic epilepsy since early childhood is studied in late stages of the disease. Spectral analysis shows that parietal 4-7 cps rhythms (theta rhythms) which are typical of the EEG in the early stages of the disorder can still exist in the[…][ncbi.nlm.nih.gov]
