OBJECTIVE To compare hemispherectomy patients with different pathologic substrates for hospital course, seizure, developmental, language, and motor outcomes. METHODS The authors compared hemispherectomy patients (n = 115) with hemimegalencephaly (HME; n = 16), hemispheric cortical dysplasia (hemi CD; n = 39), Rasmussen encephalitis (RE; n = 21),(More)
OBJECTIVE Epilepsy neurosurgery is a treatment option for children with refractory epilepsy. Our aim was to determine if outcomes improved over time. METHODS Pediatric epilepsy surgery patients operated in the first 11 years (1986-1997; pre-1997) were compared with the second 11 years (1998-2008; post-1997) for differences in presurgical and postsurgical(More)
PURPOSE Young children with refractory symptomatic epilepsy are at risk for developing neurologic and cognitive disabilities. Stopping the seizures may prevent these disabilities, but it is unclear whether resective surgery is associated with adequate long-term seizure control. METHODS This study determined pre- and postsurgery seizure frequency and(More)
PURPOSE Traumatic brain injury (TBI) is an important cause of morbidity and mortality in children, and early posttraumatic seizures (EPTS) are a contributing factor to ongoing acute damage. Continuous video-EEG monitoring (cEEG) was utilized to assess the burden of clinical and electrographic EPTS. METHODS Eighty-seven consecutive, unselected (mild -(More)
OBJECT Cerebral hemispherectomy for intractable seizures has evolved over the past 50 years, and current operations focus less on brain resection and more on disconnection. In addition, cases involving cortical dysplasia and Rasmussen encephalitis are being identified and surgically treated in younger individuals. Few studies have been conducted to compare(More)
Children undergoing surgery with infant-onset epilepsy were classified into those with medically refractory infantile spasms (IS), successfully treated IS, and no IS history, and the groups were compared for pre- and postsurgery clinical and Vineland Adaptive Behavior Scale (VABS) developmental quotients (DQ). Children without an IS history were older at(More)
The authors assessed whether magnetoencephalography/magnetic source imaging (MEG/MSI) identified epileptogenic zones in patients with tuberous sclerosis complex (TSC). In six TSC children with focal seizures, ictal video-EEG predicted the region of resection with 56% sensitivity, 80% specificity, and 77% accuracy (p = 0.02), whereas interictal MEG/MSI fared(More)
PURPOSE Acute postoperative seizures (APOSs) are those that occur in the first 7 to 10 days after surgery, and previous studies in temporal lobe epilepsy patients support the notion that APOSs may foretell failure of long-term seizure control. It is unknown whether APOSs also predict seizure outcome or hospital course after hemispherectomy. METHODS(More)
OBJECTIVE To evaluate whether diffusion tensor imaging (DTI) can predict epileptogenic tubers by measuring apparent diffusion coefficient (ADC), fractional anisotropy, axial diffusivity, and radial diffusivity in both tubers and perituberal tissue in pediatric patients with tuberous sclerosis complex (TSC) undergoing epilepsy surgery. METHODS We(More)
OBJECTIVE To examine formal thought disorder and discourse (cohesive) devices that make speech coherent prospectively in seven children, aged 5.7 to 16.7 years, before and after temporal lobectomy for intractable cut points determined from sensitivity and specificity analyses of formal thought disorder and discourse measures in 22 children with complex(More)
