BACKGROUND AND PURPOSE The purpose of this study was to evaluate the mutation status of PANK2 among Korean patients with pantothenate kinase-associated neurodegeneration (PKAN) and to document the outcome of pallidal deep brain stimulation (DBS). METHODS Direct sequencing and deletion/duplication analysis of PANK2 were conducted in 12 patients (11(More)
PURPOSE To compare the efficacy of corpus callosotomy and vagus nerve stimulation (VNS) for long-term adjunctive therapy in children with Lennox-Gastaut syndrome (LGS). METHOD Fourteen patients underwent a total corpus callosotomy and 10 patients received VNS implantation. The patients were monitored for more than 12 months after treatment, and seizure(More)
OBJECTS The aim of this study was to evaluate the role of surgical modality in children with brain tumors and intractable epilepsy. METHODS Twenty-three patients who were treated for brain tumors and intractable epilepsy between January 1985 and March 1998 were retrospectively reviewed. The most common tumors were dysembryoplastic neuroepithelial tumors(More)
OBJECTIVE There are a few reports on the complications of surgery for epilepsy. We surveyed our data to present complications of epilepsy surgeries from the neurosurgeon's point of view and compare our results with other previous reports. METHODS A total of 179 surgical procedures for intractable epilepsy (41 diagnostic, 138 therapeutic) were performed in(More)
OBJECTIVE Intracranial aneurysms are sometimes presented with visual symptoms by their rupture or direct compression of the optic nerve. It is because their prevalent sites are anatomically located close to the optic pathway. Anterior communicating artery is especially located in close proximity to optic nerve. Aneurysm arising in this area can produce(More)
PURPOSE Our goal was to compare the diagnostic accuracy of subjective visual assessment versus MR volumetry in evaluating hippocampal sclerosis and to determine whether MR volumetry is needed in the lateralization of this disease process. METHODS MR imaging findings were studied retrospectively in 48 patients who underwent surgery for temporal lobe(More)
OBJECTIVE To present our experience with vagus nerve stimulation (VNS) and to evaluate the long-term efficacy and safety of the procedure in pediatric intractable epilepsy. METHODS This study included sixteen patients, who were implanted with a vagus nerve stimulator and could be followed up for at least more than 12 months in two epilepsy centers. Data(More)
The cerebellum is known to have an inhibitory effect on seizures. Nevertheless, cerebellar dysplastic lesions can be epileptogenic. A 4-month-old infant had paroxysmal facial contractions; tachypnea and nystagmoid eyeball and tremulous movements were occasionally combined. These evolved to stereotypic clinical patterns and frequencies, which increased(More)
BACKGROUND Electrical stimulation is currently employed to treat several neurological conditions, including pain and Parkinson's disease. It is one of several minimally invasive alternatives to drug treatments for painful conditions. A number of studies have shown that the anterior cingulate cortex (ACC) plays an important role in the processing of pain and(More)
In order to elucidate the radiological features of dysembryoplastic neuroepithelial tumor (DNT), and to clarify the optimal surgical strategy for this tumor, the authors retrospectively analyzed 20 cases of DNT treated at our institution. Magnetic resonance (MR) imaging (all cases), 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET) (eight(More)
