Clinical and EEG findings in complex partial status epilepticus with tiagabine

Abstract

A case of complex partial status epilepticus (CPSE) with high dose treatment of tiagabine (TGB) is reported. Seizure aggravation and CPSE developed after stepwise increase of TGB to a dose of 60 mg per day as add-on treatment to carbamazepine (CBZ) 1200 mg/day and vigabatrine (VGB) 1000 mg/day. The EEG during CPSE showed bilateral rhythmic slow activity. Clinical symptoms of CPSE and the EEG normalized after i.v. treatment with clonazepam. The literature and the possible mechanism of this paradoxical phenomenon are discussed.
