Tonic status epilepticus in patients with idiopathic generalized epilepsy

Epileptic Disord. 2005 Dec;7(4):327-31.

Abstract

Rationale: 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.

Methods: We retrospectively reviewed the clinical and EEG evaluation of three IGE patients who presented TSE.

Results: The three patients had mainly clinical features of IGE, but had developed, in addition, focal discharges, diffuse EEG abnormalities and some focal or diffuse neuropsychological dysfunction. The tonic attacks eventually responded to treatment, but were not completely controlled in any of the patients.

Discussion: The continuum between IGE and secondary generalized epilepsy is demonstrated in these patients. Most of their clinical and EEG features are however, in keeping with an idiopathic generalized epileptic process with additional focal and diffuse components. Recognition of the significance of TSE in such patients has important therapeutic and prognostic implications. [Published with video sequences].
