BACKGROUND Mood disorder is a frequent complication of stroke. Comorbid depressive and anxiety disorders are very common, indicating that it is advisable to assess both disorders at the same time. The aim of the present study was to examine the prevalence of post-stroke depression (PSD) and poststroke anxiety (PSA) at baseline and to evaluate factors(More)
Non-contrast enhanced computed tomography (NCCT) is usually performed to estimate bleeding complications immediately after procedures. However, hyperdense areas on NCCT have not yet been understood; different interpretations have been reported in the literature. It remains unclear whether NCCT performed immediately after intra-arterial revascularization(More)
Astrocytes become reactive after central nervous system injury, re-expressing glial fibrillary acidic protein (GFAP), vascular endothelial growth factor (VEGF), and nestin. Hypoxia-inducible transcription factor alpha (HIF-1α) is an important transcription factor for several genes including the VEGF and nestin genes, the expression of which generate(More)
We aimed to elucidate whether the eNOS T-786C mutant allele is implicated in subarachnoid hemorrhage (SAH) susceptibility or vasospasm after SAH, and whether the mutant allele is differentially expressed in those with small and large ruptured aneurysms in Korean population. 136 consecutive patients diagnosed with aneurismal SAH and 113 controls were(More)
BACKGROUND Brain derived neurotrophic factor (BDNF) has been shown to play an important role in poststroke recovery. BDNF secretion is influenced by genetic and epigenetic profiles. This study aimed to investigate whether BDNF val66met polymorphism and promoter methylation status were associated with outcomes at two weeks and one year after stroke. (More)
BACKGROUND Human infection with Streptococcus suis (S. suis), a zoonotic pathogen, has been reported mainly in pig-rearing and pork-consuming countries. Meningitis is the most-common clinical manifestation and is often associated with deafness and vestibular dysfunction. CASE REPORT A 57-year-old man was referred to the hospital with headaches, fevers,(More)
INTRODUCTION This study aimed to compare screening properties of four assessment scales for poststroke depression (PSD) at 2 weeks and 1 year after index stroke, and investigated factors contributing to misclassification. METHODS A total of 423 patients were evaluated 2 weeks after stroke and 288 (68%) were followed 1 year later, and were diagnosed as(More)
BACKGROUND Polymorphisms of serotonin transporter (5-HTT) and brain-derived neurotrophic factor (BDNF) have been investigated as candidate genes for post-stroke depression (PSD). Serotonin 2a receptor (5-HTR2a) genes have not been yet investigated in PSD. This study aimed to investigate whether the 5-HTT, 5-HTR2a, and BDNF genes are associated with PSD(More)
The antioxidant properties of alpha-lipoic acid (aLA) correlate with its ability to promote neuroproliferation. However, there have been no comprehensive studies examining the neurorestorative effects of aLA administration after the onset of ischemia. The middle cerebral artery (MCA) of adult rats was occluded for 2 hours and then reperfused. aLA (20 mg/kg)(More)
BACKGROUND Untreated acute mild stroke patients have substantial 90-day disability rates and worse outcomes than those who are treated with thrombolysis. There is little information regarding which patients with acute mild stroke will benefit from thrombolysis. We sought to investigate factors that are associated with early neurological deterioration (END)(More)
