We report a characteristic pattern of neuropathological change in the entorhinal cortex (EC) from four patients with temporal lobe epilepsy. Specimens of the EC were obtained during the surgical treatment of intractable partial seizures and were studied by light microscopy in Nissl-stained sections. A distinct loss of neurons was observed in the anterior(More)
OBJECTIVE To evaluate the efficacy and safety of 500 mg bid and 1500 mg bid levetiracetam as adjunctive therapy for refractory partial seizures in a double-blind, randomized, placebo-controlled, parallel-group, multicenter trial. METHODS The authors studied patients with uncontrolled partial seizures (minimum 12 per 12 weeks), regardless of whether they(More)
OBJECTIVE To assess the evidence demonstrating efficacy, tolerability, and safety of seven new antiepileptic drugs (AEDs) (gabapentin, lamotrigine, topiramate, tiagabine, oxcarbazepine, levetiracetam, and zonisamide) in the treatment of children and adults with refractory partial and generalized epilepsies. METHODS A 23-member committee including general(More)
BACKGROUND Generalized epilepsy with febrile seizures plus (GEFS+) is an autosomal dominant syndrome characterized by febrile seizures (FS) and a variety of afebrile generalized seizure types. GEFS+ has previously been linked to mutations in two genes encoding the voltage-gated sodium channel alpha-subunit (SCN1A) and beta1-subunit (SCN1B). We studied a(More)
Epileptic encephalopathies are a devastating group of severe childhood epilepsy disorders for which the cause is often unknown. Here we report a screen for de novo mutations in patients with two classical epileptic encephalopathies: infantile spasms (n = 149) and Lennox-Gastaut syndrome (n = 115). We sequenced the exomes of 264 probands, and their parents,(More)
OBJECTIVE To evaluate the safety and efficacy of oxcarbazepine (OXC) as adjunctive therapy in children with inadequately controlled partial seizures on one or two concomitant antiepileptic drugs (AEDs). BACKGROUND OXC has shown antiepileptic activity in several comparative monotherapy trials in newly diagnosed patients with epilepsy, and in a(More)
BACKGROUND A proportion of patients with epilepsy are still without seizure control. This open study aims to evaluate the effect and tolerability in consecutive patients treated with the new antiepileptic drug levetiracetam. MATERIALS AND METHODS 184 adult patients were followed up for an average period of 8.1 months. 166 patients (90%) had refractory(More)
BACKGROUND Although epileptic seizures occur more commonly in older adults, their occurrence in this age group is often unexplained. One unexplored precipitant of seizures in older adults is obstructive sleep apnea (OSA), which is also more common in this age group. Our objective was to investigate whether OSA is associated with seizure exacerbation in(More)
PURPOSE To describe our experience with levetiracetam (LEV) as initial or conversion monotherapy treatment for juvenile myoclonic epilepsy (JME). Valproate, the usual first line agent for JME, has chronic adverse effects, particularly for women of childbearing potential. Since JME requires lifetime treatment, chronic adverse effects of therapy are important(More)
We studied biopsy results in a kindred with the Lafora form of progressive myoclonic epilepsy. Four members of a family with known consanguinity presented as teenagers with seizures, myoclonus, dementia, and ataxia. After the diagnosis was established by brain biopsy in the first patient, many efforts were made to obtain a tissue diagnosis in the three(More)
