Clinical experience in open-label studies and anectodal reports suggest that levetiracetam is effective in generalized epilepsy. In this open-label prospective study, 19 patients (3 men, 16 women) affected by idiopathic generalized epilepsy were followed for at least 6 months following the introduction of levetiracetam. Patients were categorized according to syndrome subtype: juvenile myoclonic...

Heron and colleagues (Ann Neurol 2004;55:595-596) identified three missense mutations in the Cav3.2 T-type calcium channel gene (CACNA1H) in patients with idiopathic generalized epilepsy. None of the variants were associated with a specific epilepsy phenotype and were not found in patients with juvenile absence epilepsy or childhood absence epilepsy. Here, we introduced and functionally charact...

PURPOSE Idiopathic focal epilepsies in childhood including benign childhood epilepsy with occipital paroxysms (BEOP) or benign childhood epilepsy with centro-temporal spikes (BCECTS) are characterized by specific focal electrographic patterns as the name indicates. Generalized spike-wave discharges in children with idiopathic focal epilepsy can suggest a neurobiological continuum with the idiop...

PURPOSE Evaluate the efficacy of carbamazepine in the treatment of idiopathic generalized epilepsy (IGE). METHOD The response of five patients with IGE, who experienced primarily generalized tonic-clonic seizures which were refractory to multiple antiepileptic drugs, is reported. RESULTS Carbamazepine controlled multiple seizure types and did not induce or increase the frequency of myocloni...

BACKGROUND AND PURPOSE There are reports of successful resective epilepsy surgery for pediatric patients with epilepsy and generalized epileptiform discharges when they had focal epileptogenic lesions identified by MRI. However, there is limited information regarding adult patients with epilepsy who have both generalized epileptiform discharges and focal epileptogenic lesions. METHODS To inve...

PURPOSE To compare subclinical balance dysfunction in patients with various epilepsy syndromes with apparently healthy subjects. METHODS Twenty-seven patients with localization-related epilepsy (LRE), 19 with primary generalized epilepsy (PGE), who had no subjective complaints of impaired balance and no abnormal neurologic findings on examination, and 22 apparently healthy subjects, underwent...

Absence status epilepticus is characterized by a prolonged state of impaired consciousness or altered sensorium with generalized electroencephalographic abnormalities. It is most commonly diagnosed in patients with known idiopathic generalized epilepsy; however, it may also be the first presentation of epilepsy. Due to the subtle and variable manifestations of the condition, absence status epil...

The characterization of a seizure as generalized or focal onset depends on a basic knowledge of the underlying pathophysiology. Recently, an uncommon phenomenon in generalized epilepsy-evolution of seizures from generalized to focal followed by secondary generalization-was reported for the first time. We describe a 15-year-old boy, initially classified as having partial epilepsy, who had a typi...

OBJECTIVE To use transcranial magnetic stimulation (TMS) to investigate the hypothesis that sleep deprivation increases cortical excitability in people with epilepsy. METHODS We performed paired pulse TMS stimulation, using a number of interstimulus intervals (ISIs) on each hemisphere of 30 patients with untreated newly diagnosed epilepsy (15 idiopathic generalized epilepsy [IGE] and 15 focal...
