OBJECTIVE: Aphasia is a common presentation of ischemic stroke, often diagnosed in the acute setting using tools such as the NIH Stroke Scale (NIHSS). Due to the vascular distribution of the middle cerebral artery, it is often accompanied by other symptoms such as weakness, sensory loss, or visual changes. Isolated aphasia due to ischemia is possible, but language problems mimicking aphasia syndromes can also be seen with other diagnoses such as metabolic abnormalities or dementia. In this study, we determine the incidence of aphasia-only strokes using the NIHSS, and factors associated with a higher likelihood of ischemia...

BACKGROUND: Clinical trials have showed that robust collateral flow has a relationship with good clinical outcome, however, different stroke subtypes were lumped together. This study explored the relationship between baseline collaterals and the onset-to-imaging time (OIT), and the correlation between pre-treatment collateral status and clinical outcome among different subtypes. METHOD: We reviewed prospectively collected data from consecutive acute ischemic stroke (AIS) patients with acute middle cerebral artery occlusion who received reperfusion therapy...

BACKGROUND: Ischemic stroke (IS) is an extremely heterogeneous disease with variable pathogenesis. Due to the lack of early diagnostic markers, the mortality rate of IS remains high. Cumulative evidence shows that long noncoding RNAs among noncoding RNAs play important roles in cardiovascular diseases. In the present study, we focused on the expression pattern of myocardial infarction-associated transcript (MIAT) and its clinical significance in IS. METHODS: Blood samples were obtained from IS patients (n = 189) and healthy controls (n = 189)...
