Levetiracetam (LEV) is effective for treating localisation-related epilepsy, but it is uncertain whether it is effective for treating idiopathic generalised epilepsy. We compared 12-week baseline and LEV treatment periods for patients with generalised seizure types-myoclonic, tonic-clonic and absence seizures--who had failed other anticonvulsants. The majority of 55 patients (76%) had >50% seiz...

A 38-year-old man had postictal global aphasia after generalized tonic-clonic seizure, but recovered within 1 day. There was a focal increase in the signal intensity of the left frontoparietal sulci on fluid-attenuated inversion recovery magnetic resonance (MR) sequence 6 hours after the seizure, which disappeared 1 month later. The transient seizure-induced MR hyperintensity was possibly cause...

The dynamical characteristics of a complex system can be inferred from an observation of the system. In this paper, a calculation algorithm of the damping time of a signal from a complex system is presented by using information retrieve and autoregressive model. Two EEG recordings during tonic–clonic seizure are analyzed; the damping time of EEG calculated by means of the proposed algorithm can...

A 37-year-old woman experienced a generalized tonic-clonic seizure. Subsequent to the seizure, the patient observed left-sided face and neck pain. A left Horner syndrome was noted on examination. AnMRI and magnetic resonance angiogram revealed a left skull base carotid artery dissection without infarction (figure, A and B). Previous MRI had shown normal carotid flow voids. The patient was treat...

A sample of 78 patients (32 females and 46 males) who had a first unprovoked generalized tonic-clonic seizure between the age of 3 and 21 years was studied prospectively. Duration of follow-up was 2-10 years (mean 5.2 years). A second seizure occurred in 69.2% (54 of 78), most commonly (38 of 54, 70.37%) in the first three months after the first seizure. There were no significant differences in...

PURPOSE This study investigated the duration of generalized tonic-clonic seizure (GTCS) and the factors that prolong GTCS duration. METHOD We retrospectively analyzed clinical data collected from a consecutive group of patients who underwent video-electroencephalography (EEG) and experienced at least one GTCS during monitoring. Each seizure was divided into seven phases. The duration of GTCS ...

A 35-yr-old woman carrying a 17-week-old fetus presented with right hydronephrosis and a single umbilical artery. Karyotyping was normal and targeted ultrasonography showed an otherwise normal fetus. After 28 weeks of gestation, the mother felt rapid, repetitive fetal movement and an ultrasound at 30 weeks of gestation revealed tonic clonic movements of the fetal trunk and extremities. At 36 we...
