We determined the interrelations of chronological age, age at seizure onset, duration of seizure disorder, cognitive functioning (IQ), scales of activities of daily living, depressive mood disorder and measures of health-related quality of life (HRQOL). Furthermore, we investigated the association of the laterality of seizure onset zone and absence/presence of hippocampal atrophy and/or scleros...

OBJECTIVE The coincidence of autism with epilepsy is 27% in those individuals with intellectual disability.1 Individuals with loss-of-function mutations in SHANK3 have intellectual disability, autism, and variably, epilepsy.2-5 The spectrum of seizure semiologies and electroencephalography (EEG) abnormalities has never been investigated in detail. With the recent report that SHANK3 mutations ar...

Let g ∈ Q be not −1 or a square. Let Pg denote the set of primes p such that g is a primitive root mod p. Let 1 ≤ a ≤ f, (a, f) = 1. Under the Generalized Riemann Hypothesis (GRH) it can be shown that the set of primes p ∈ Pg with p ≡ a(mod f) has a natural density. In this note this density is explicitly evaluated. This generalizes a classical result of Hooley.

In this paper, we introduce a modification of a mean-field model used to describe the brain's electrical activity as recorded via electroencephalography (EEG). The focus of the present study is to understand the mechanisms giving rise to the dynamics observed during absence epilepsy, one of the classical generalized syndromes. A systematic study of the data from a number of different subjects w...

An unusual case of primary meningo-encephalitis followed by partial complex seizure in a 9-year-old boy was found to be a symptom of cerebral Bartonella henselae infection or cat scratch disease. Despite one clinical relapse at 4 weeks post-presentation, he remained seizure free on carbamazepine for one year. Six months after stopping carbamazepine, however, he developed deja vu phenomena and a...

Valproic acid is a new antiepileptic drug recently introduced in the United States for the treatment of absence seizures. In this study on patients with absence and other seizure types, the majority of patients achieved optimal control within four weeks of therapy. No patient responded to valproic acid who did not show an initial clinical response by four weeks of active therapy. Optimal respon...

Abstract Objective Presurgical cognitive and psychiatric status can serve as predictors of surgical outcomes; however, there are no studies that assess the predictive nature factors illness on seizure freedom following stereotactic laser ablation, a novel, minimally invasive approach, hippocampus (SLAH). Therefore, this study aimed to whether neuropsychological were associated with long-term po...

We investigated the correlation of interictal epileptiform discharges (IED) in routine EEG 6 and 24 months after epilepsy surgery with regard to long-term seizure outcome. In 148 patients (74% temporal lobe epilepsy (TLE), 26% extratemporal epilepsy) EEG results (IED present or absent) were correlated with the postoperative outcome using the Engel classification 6 and 24 months after resection ...

Synchronous and bilateral spike-and-wave discharges accompany nonconvulsive behavioral and cognitive arrest during seizures associated with absence epilepsy. Previous investigation of multiple absence animal models suggests that the underlying cause of absence seizures is an increase in thalamic inhibitory tonic currents. In contrast, in this study we provide evidence that the level of cortical...
