OBJECTIVE For about 30% of epilepsy patients, pharmaceutical therapy fails to control their seizures. MR-guided laser interstitial thermal therapy (MRgLITT) allows for real-time thermal monitoring of the ablation process and feedback control over the laser energy delivery. We report on minimally invasive surgical techniques of MRgLITT and short-term(More)
BACKGROUND Almost a third of patients with epilepsy have a treatment-resistant form, which is associated with severe morbidity and increased mortality. Cannabis-based treatments for epilepsy have generated much interest, but scientific data are scarce. We aimed to establish whether addition of cannabidiol to existing anti-epileptic regimens would be safe,(More)
This chart review investigated the efficacy and safety of zonisamide in 45 patients aged < or = 18 years with absence seizures. Of these patients, 23 (51.1%) achieved freedom from absence seizures. Two patients discontinued zonisamide, 1 for increased seizures and 1 for sleepiness and inefficacy. These data support the efficacy of zonisamide in treating(More)
The authors evaluated zonisamide for symptomatic infantile spasms in 23 patients. Spasm cessation, EEG evolution, and tolerability were assessed for a mean duration of 6.5 months. Six patients (26%) had complete control with cessation of spasms and clearing of hypsarrhythmia. Mean latency time from onset of zonisamide treatment to complete spasm control was(More)
The nature and extent of the neuropsychological difficulties associated with childhood absence epilepsy (CAE) remain unclear. Because aberrant thalamocortical rhythms have been implicated in the pathogenesis of CAE, it was hypothesized that children with CAE would show greater difficulties in neuropsychological domains that are thought to be subserved by(More)
Several of the newer antiepilepsy drugs have not been tested as monotherapy in controlled trials. Zonisamide is a broad-spectrum antiepilepsy drug indicated for the adjunctive treatment of partial seizures in adults. However, several small, open-label studies have indicated that it may be safe and effective as monotherapy. The present chart review study was(More)
A retrospective analysis of 43 patients with drop attack seizures who were treated with vagus nerve stimulation (VNS) was undertaken to determine the efficacy of VNS and to determine pre-implantation characteristics associated with VNS success. It was found that on last follow-up, 46% of patients had at least a 75% reduction in drops per day. Forty-six(More)
Hypothalamic hamartomas (HHs) present a difficult medical problem, manifested by gelastic seizures, which are often medically intractable. Although existing techniques offer modest surgical outcomes with the potential for significant morbidity, the relatively novel technique of magnetic resonance imaging (MRI)-guided stereotactic laser ablation (SLA) offers(More)
Use of vagus nerve stimulation (VNS) has increased in the past decade, resulting in frequent revision cases for device failure. The authors report their series of children who underwent reimplantation of the VNS device after removal of old electrodes and leads. Patients with medically refractory seizures who underwent revision of VNS electrodes were(More)
This case series presents the outcomes of seven females with Rett syndrome and medically refractory epilepsy who were treated with adjunctive vagus nerve stimulation (VNS) therapy for a minimum of 12 months. Patients ranged in age from 1 to 14 years (median age 9 y) at the time of implantation, had experienced seizures for a median period of approximately 6(More)
