Nearly one third of patients with epilepsy become medically intractable, and the likelihood of achieving seizure freedom decreases with each additional medication trial. For appropriately chosen patients, epilepsy surgery affords the opportunity to achieve seizure freedom and potentially wean off medications. Epilepsy surgery, as with medical management, is(More)
The internet has become the first stop for the public and patients to seek health-related information. Video-sharing websites are particularly important sources of information for those seeking answers about seizures and epilepsy. Because of the widespread popularity of YouTube, we sought to explore whether a seizure diagnosis and classification could(More)
DNM1L encodes dynamin-related protein 1 (DRP1/DLP1), a key component of the mitochondrial fission machinery that is essential for proper functioning of the mammalian brain. Previously reported probands with de novo missense mutations in DNM1L presented in the first year of life with severe encephalopathy and refractory epilepsy, with several dying within(More)
Approximately 30% of epilepsy patients are medically intractable. Epilepsy surgery may offer cure or palliation, and neuromodulation and direct drug delivery are being developed as alternatives. Successful treatment requires correct localization of seizure onset zones and understanding surrounding functional cortex to avoid iatrogenic disability. Several(More)
PURPOSE To describe three cases of refractory status epilepticus (RSE) in children responsive to topiramate (TPM). METHODS Patients with SE refractory to therapeutic doses of at least two antiepileptic medications were given TPM, 10 mg/kg/d, for 2 consecutive days, followed by maintenance doses of 5 mg/kg/d. RESULTS This protocol has been used in three(More)
Sengers syndrome is characterized by a constellation of congenital cataracts, hypertrophic cardiomyopathy, skeletal myopathy, and lactic acidosis. Two forms of the disease have been described: a fatal neonatal form, and a more benign form in which patients live into their second or third decades. With the exception of time to death, no findings have(More)
PURPOSE To review our experience of the efficacy and tolerability of levetiracetam (LEV) in children younger than 4 years. METHODS We used retrospective chart review to identify 122 children with seizures who were younger than 4 years and followed for >or=6 months. Efficacy was evaluated on the basis of the occurrence and durability of seizure remission.(More)
Palliative epilepsy surgery is considered for patients that would benefit from surgical therapy for intractable epilepsy but are not candidates for curative procedures. In many cases, the goals of therapy focus on improved quality of life more than seizure freedom. We discuss the use of epilepsy surgery for refractory status epilepticus, as well as the(More)
OBJECTIVE Incomplete resection of the epileptogenic zone (EZ) is the most important predictor of poor outcome after resective surgery for intractable epilepsy. We analyzed the contribution of preoperative and perioperative variables including MRI and EEG data as predictors of seizure-free (SF) outcome after incomplete resection. METHODS We retrospectively(More)
heterotopia in fragile X syndrome Abstract—The authors describe two unrelated individuals with fragile X syndrome (FXS) due to marked expansion and instability of the CGG trinucleotide repeats within the fragile X mental retardation 1 gene (FMR1) and periventricular heterotopia (PH). This observation suggests that the FMR1 gene is involved in neuronal(More)
