BACKGROUND AND PURPOSE Stent placement for intracranial atherosclerosis has become an alternative treatment technique; however, stent placement for middle cerebral artery (MCA) stenosis remains a technical and clinical challenge. Our purpose was to assess the feasibility, safety, and effectiveness of stent placement for MCA stenosis. METHODS Between May(More)
Cerebral ischemia increases neural progenitor cell proliferation and neurogenesis. However, the precise molecular mechanism is poorly understood. The present study was undertaken to determine roles of extracellular signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/Akt and their signaling pathways in neural progenitor cells exposed to(More)
We assessed knowledge and perceptions of epilepsy held by Korean adolescents in the general population, and investigated factors important in adolescents' perceptions of stigma with respect to epilepsy. Surveys were distributed to students at 22 schools. A total of 1377 students participated. Fewer than half of all students (45.1%) reported hearing or(More)
We investigated factors contributing to teachers' attitudes toward students with epilepsy. Data were collected from 604 teachers in Korea. The questionnaire included the Scale of Attitudes Toward Persons with Epilepsy (ATPE) and a demographic and teaching experience survey. In stepwise linear regression analysis, ATPE Knowledge scores (P<0.001) and prior(More)
BACKGROUND AND PURPOSE Dissections of the carotid and vertebral arteries can be detected by several imaging modalities, but there is yet no consensus on the most efficient and effective choice. METHODS We performed diffusion-weighted imaging (DWI) in four patients with vertebral artery dissection documented with T2- and T1-weighted axial magnetic(More)
Using a frozen section technique, we have assessed the effects of N-methyl-D-aspartate (NMDA) antagonist upon brain swelling caused by ischemic brain edema in a rat model of focal cerebral infarction. Although pretreatment with the competitive NMDA antagonist, D-CPPene or the noncompetitive NMDA antagonist, CNS 1102 reduced both the volumes of infarction(More)
We describe detailed clinical, biochemical, neuroimaging and neuropathological features in adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), encompassing hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS) and pigmentary orthochromatic leukodystrophy (POLD), linked to colony-stimulating factor 1 receptor(More)
BACKGROUND Tonic inward and downward deviation of the eyes ("peering at the tip of the nose") is regarded as a unique feature of thalamic hemorrhage, but the mechanisms of this ocular finding remain obscure. OBJECTIVES To describe 4 patients who showed tonic inward and downward deviation of the eyes from brainstem or thalamic lesions and to discuss the(More)
BACKGROUND AND PURPOSE Susceptibility-weighted imaging (SWI) can show an intravascular thrombus as a hypointense susceptibility vessel sign (SVS). In this study, we investigated the usefulness of SWI in the detection of an intravascular thrombus in acute cardioembolic stroke by comparing the SVS on SWI to the vessel status on time-of-flight magnetic(More)
