Early infarct growth predicts long-term clinical outcome in ischemic stroke
Ischemic lesions dynamically evolve during the acute phase of stroke. Although the ischemic lesion volume has been considered as a predictor of clinical outcome, it is still controversial whether early changes in ischemic lesion have prognostic information in addition to clinical variables. We hypothesized that early infarct growth on diffusion-weighted imaging (DWI) might be independently associated with long-term outcome in acute ischemic stroke patients.

Altered spontaneous activity in the default-mode network and cognitive decline in chronic subcortical stroke
The resting-state functional connectivity (rsFC) has been reported to be impaired in the default-mode network (DMN) in stroke patients. However, it remains unclear whether the regional homogeneity (ReHo) of spontaneous activity and gray matter volume (GMV) are also altered in the DMN in these patients. Here we investigated ReHo, rsFC and GMV changes in the DMN and their functional correlations in stroke patients.

Can botulinum toxin type A injection technique influence the clinical outcome of patients with post-stroke upper limb spasticity? A randomized controlled trial comparing manual needle placement and ultrasound-guided injection techniques
Botulinum toxin type A is a first-line treatment for post-stroke focal spasticity, and the accuracy in delivering the toxin to the target muscles may influence the treatment outcome. Our aim was to compare the reduction of spasticity and the related finger position at rest improvement in post-stroke patients treated with botulinum toxin type A in upper limb muscles using ultrasound guidance and manual needle placement.

The post-stroke clotting battle: ADAMTS13 falls and puts out of control vWF into brain arteries
A war among pro-coagulant, anti-coagulant, pro-fibrinolytic and anti-fibrinolytic cascades may generate a stroke; probably acute stroke is the final big battle and if there is no peace following that bloody fighting, thousands of neurons will die….

Association between beta -1 adrenergic receptor gene polymorphism and ischemic stroke in North Indian Population: A case control study
In this study, 224 patients and 224 age-and sex-matched controls were recruited from Outpatient Department and neurology ward of All India Institute of Medical Sciences New Delhi. Genotyping was performed by using Polymerase chain reaction–Restriction fragment length polymorphism (PCR-RFLP) method.

Bedside evaluation of smooth pursuit eye movements in acute sensory stroke patients
Unilateral saccadic pursuit is reported to be suggestive of a pontine lesion in sensory stroke patients. We attempted to verify this eye sign in just-hospitalized pontine sensory stroke patients.

Executive dysfunction is a strong stroke predictor
Although stroke is known to result in executive dysfunction, little is known about executive dysfunction as a risk factor for stroke.

Stroke admission and case-fatality in an urban medical unit in sub-Saharan Africa: A fourteen years trend study from 1999 to 2012
Data on recent stroke trends in the context of rapidly deteriorating risk profile of populations within Africa is very limited. We investigated the admission trend for stroke and related outcomes in a major referral hospital in Cameroon.

Arterial spin-labeling magnetic resonance imaging for diagnosis of early seizure after stroke
Arterial spin-labeling (ASL) is a non-contrast-enhanced sequence of magnetic resonance imaging (MRI) to evaluate cerebral perfusion. ASL has been widely used in cerebrovascular diseases [1]. Previously, we reported the use of ASL for the diagnosis of late seizure after stroke [2]. Here we report a first case of ASL in a patient with early seizure after stroke.

Orthodeoxia-platypnea syndrome and stroke: Overlapping pathophysiology
Orthodeoxia-platypnea syndrome (OPS) is a rare cause of dyspnea and hypoxemia induced by upright positioning due to orthostatic conditions [1]. Right-to-left interatrial shunt due to an atrial septal defect or patent foramen ovale (PFO) is the most common cause of this syndrome [2]. Although PFO has been implicated as a potential cause of paradoxical embolism and cerebral embolism in cryptogenic stroke [3], OPS due to PFO has rarely been described presenting as stroke [2,4,5].
