Psychiatric sequelae of stroke affecting the non-dominant cerebral hemisphere
There are a plethora of cognitive sequelae in addition to neglect and extinction that arise with unilateral right hemispheric stroke (RHS). Cognitive deficits following non-dominant (right) hemisphere stroke are common with unilateral neglect and extinction being the most recognized examples. The severity of RHS is usually underestimated by the National Institutes of Health Stroke Scale (NIHSS), which in terms of lateralized right hemisphere cognitive deficits, tests only for visual inattention/extinction.

Significance of concurrent ipsilateral intracranial carotid artery stenosis in carotid revascularization
A 71-year-old male presenting with a transient ischemic attack was found to have an ipsilateral severe proximal right internal carotid artery (ICA) stenosis as graded per the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. He was subsequently treated with right internal carotid endarterectomy (CEA). The surgery was complicated by a right sided watershed infarction determined by magnetic resonance imaging (MRI) of the head. His post-surgery National Institutes of Health Stroke Scale score was 6 and the 90  days modified Rankin Scale score was 3.

Ultra-early improvement after endovascular thrombectomy and long-term outcome in anterior circulation acute ischemic stroke
The use of post-treatment measures after acute ischemic stroke is important to predict good functional outcome. The most studied is 24  h National Institutes of Health Stroke Scale (NIHSS) score and existing literature is scarce regarding the use of earlier indicators, namely NIHSS immediately after endovascular thrombectomy (EVT). We hypothesized that an immediate neurological improvement after EVT, that we called ultra-early ne urological improvement (UENI), would be a reliable functional independence predictor in anterior circulation acute ischemic stroke patients.

Association between initial NIHSS score and recanalization rate after endovascular thrombectomy
National institutes of Health Stroke Scale (NIHSS) score and the presence of successful recanalization are crucial determinants of clinical outcome in patients with major artery occlusion. However, it is unknown whether successful recanalization rate after endovascular therapy (EVT) depends on NIHSS score.

Gadolinium enhancement in perforating arteries in a patient with varicella zoster virus vasculopathy: A case report
A 35-year-old man was admitted to our hospital because of right hemiparesis. His initial National Institutes of Health Stroke Scale score was 8. He had a 1-week history of fever and headache that had occurred approximately 1  month prior to admission. Diffusion-weighted imaging on admission showed hyperintensities in the left putamen and corona radiata (Supplementary Fig. 1). There were no atherosclerotic changes or findings suggesting intracranial arterial dissection or carotid artery disease on magnetic resonance (M R) angiography.

MRI based thrombolysis for FLAIR-negative stroke patients within 4.5 –6h after symptom onset
To investigate the feasibility of DWI-FLAIR mismatch in identifying patients who might benefit from thrombolytic therapy within 4.5 –6h, we analyzed the data of 105 ischemic stroke patients with known time of symptom onset who underwent MRI within 6h of stroke and thrombolysis between December 2006 and December 2013. They were divided into three groups: symptom onset within 4.5h (n=66); 4.5–6h and FLAIR images negative (n=9) ; and 4.5–6h and FLAIR images positive (n=30). Outcome of thrombolysis was assessed for each group by recanalization rate, National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS) scores.
