The aim of this study was to identify the neuroanatomical basis of the retrieval of people's names. Lesion data showed that patients with language-dominant temporal lobectomy had impairments in their ability to retrieve familiar and newly learned people's names, whereas patients with language-nondominant temporal lobectomy had difficulty retrieving newly(More)
OBJECTIVE A multicenter prospective study was performed to assess the additional value of a subtraction ictal SPECT coregistered to MRI (SISCOM) technique to traditional side-by-side comparison of ictal- and interictal SPECT images in epilepsy surgery. METHODS One hundred and twenty-three patients with temporal and extratemporal lobe epilepsy who had(More)
PURPOSE To examine the distribution of KCC2, a neuron-specific K(+)-Cl(-) cotransporter, in human cortical dysplasia (CD). METHODS The immunohistochemical expression of KCC2 was investigated in 18 CD specimens obtained during epilepsy surgery. The histopathologic diagnoses were focal CD (FCD) type I (eight cases), FCD type II (six cases), and(More)
Transmantle dysplasia is a rare type of focal cortical dysplasia (FCD) characterized by expansion of the cortex from the deep white matter to the surface and in which there is a FCD IIA or IIB pathologic pattern. To characterize possible mechanisms underlying this regional disorder of radial migrating cells, we studied the expression patterns of neocortical(More)
We describe two cases of complex partial seizures with ictal violent movements arising from the insular cortex. The first patient, a 14-year-old girl, presented with hyperkinetic behavior such as rolling, thrashing, and pedaling, and the second case, a 38-year-old woman, had been suffering from frequent daytime hyperkinetic seizures characterized by bizarre(More)
An 8-year-old boy underwent a resection for focal cortical dysplasia at the left supplementary motor area (SMA) for the treatment of intractable epilepsy. The manifestations of SMA syndrome, such as transient mutism and right hemiparesis, resolved within a few weeks. Verbal disfluency and impaired executive function, accompanied by impulsivity and(More)
OBJECTIVE Hemimegalencepahly (HME) and Hemispheric Cortical Dysplasia (HCD) are rare congenital diseases that occur with intractable epilepsy. They manifest by early epilepsy, mental retardation, hemianopsia and contralateral hemiplegia. Hemispheric disconnection (mainly anatomical hemispherectomy, peri-insular hemispherotomy, modified lateral(More)
To evaluate the effect of corpus callosotomy (CC) on attention deficit and behavioral problems in pediatric patients with intractable epilepsy, we retrospectively investigated sequential patients who had undergone CC to control seizures. Between August 2005 and April 2010, a total of 15 patients aged between 3.1 and 17.9 years underwent CC at our institute.(More)
We report a 1-year 6-month-old girl with ganglioglioma in the right medial temporal lobe who showed epileptic spasms in clusters. Spasms occasionally followed a dazed and fearful gaze. Interictal electroencephalography (EEG) showed diffuse bursts of slightly irregular high-voltage spikes and slow waves without hypsarrhythmia. The findings on ictal EEG,(More)
