BACKGROUND: Stroke may be caused by antiphospholipid antibodies (APL), especially in young persons without other risk factors. AIM: The aim of this study was to determine the prevalence of two clinically significant APL-anticardiolipin antibody (ACL) and lupus anticoagulants (LA) in young patients presenting with sudden neurological deficit. SETTINGS AND DESIGN: ...

Hypothermia is considered nature's "gold standard" for neuroprotection, and its efficacy for improving outcome in patients with hypoxic-ischemic brain injury as a result of cardiac arrest is well-established. Hypothermia reduces brain edema and intracranial pressure in patients with traumatic brain injury. By contrast, only a few small pilot studies have ...

Family history is a known non-modifiable risk factor of stroke. We aimed to compare the frequency of a family history of vascular disease between ethnic South Asian and Chinese stroke patients. We studied consecutive ethnic South Asian and Chinese ischaemic stroke patients matched for age, gender and presence of diabetes. ...

Patients with giant cell arteritis (GCA) generally present with cranial ischemic manifestations that are directly related to vascular involvement. They may also experience strokes in the territory of the carotid or the vertebrobasilar artery. We conducted the current study to assess the frequency and predictors of strokes in general, and ...

A patent foramen ovale (PFO) enables a right-to-left shunt in about a quarter of the population. The marked association between cryptogenic stroke and PFO supports the hypothesis that paradoxical embolism could be a relevant cause of stroke. Although this association has been described in several studies for patients <55 years ...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is the most common heritable cause of stroke and vascular dementia in adults. Clinical and neuroimaging features resemble those of sporadic small-artery disease, although patients with CADASIL have an earlier age at onset of stroke events, an increased frequency of ...

Recent evidence has shown that after the initial occlusion, a large portion of stroke patients achieve some degree of reperfusion either through collateral circulation or clot dissolution. However, it appears that this reperfusion may lead to increased inflammation-induced damage. Even though the exact mechanism of this secondary injury is unclear, ...

BACKGROUND: Patients with neglect often repeatedly cancel the same targets, a form of motor perseveration (MP). There seems to be 2 types of MP, making uninterrupted multiple strokes for each target, consecutive MP (CMP) or return MP (RMP) where patients return to previously canceled targets and remark them. OBJECTIVE: The ...

Lacunar stroke accounts for a quarter of cases of acute ischaemic stroke; however, its underlying pathophysiology remains unclear. Our aim was to establish whether there is an association between changes in the retinal microvasculature and lacunar stroke that might provide clues to the pathology of cerebral small vessel disease. In ...

OBJECTIVE: To investigate the difference of heart rate variability (HRV) and serum creatine kinase isoenzyme (CK-MB) activity between right-sided and left-sided stroke, and the relative impact of cardiac autonomic imbalance and heart abnormality on death by serum CK-MB activity and fractal dimension (FD) detection in patients with stroke. METHODS: Three ...

BACKGROUND AND PURPOSE: Despite numerous studies, the role of patent foramen ovale (PFO) as a risk factor for stroke due to paradoxical embolism is still controversial. On the assumption that specific lesion patterns, in particular multiple acute ischaemic lesions on diffusion-weighted magnetic resonance imaging, indicate a cardioembolic origin, we compared ...

BACKGROUND AND PURPOSE: Early deterioration can occur after acute stroke for a variety of reasons. We describe a hemodynamic steal and associated neurological deterioration, the reversed Robin Hood syndrome (RRHS). We aimed to investigate the frequency and factors associated with RRHS. METHODS: Consecutive patients with acute cerebral ischemia underwent serial ...

Bites due to Russell's Viper (Daboia russelii) are common in Sri Lanka. Commonest haematological manifestation is consumptive coagulopathy and bleeding. Commonest neurological manifestations are ptosis, ophthalmoplegia and rarely respiratory failure which are due to presynaptic inhibition of neuromuscular transmission. There are no authenticated reports of acute ischemic strokes following bites ...

Lacunar stroke is common, but the etiology of the small vessel abnormality is unknown. Retinal vessels share ontogeny, size, and physiologic characteristics with cerebral small vessels, and retinopathy is associated with stroke. We compared retinal microvessel appearance as a surrogate for cerebral small vessels in patients with lacunar and large ...

Patent foramen ovale (PFO) is significantly associated with cryptogenic stroke (CS). However, even in patients with CS, a PFO can be an incidental finding. We sought to estimate the probability that a PFO in a patient with CS is incidental. A systematic search identified 23 case-control studies examining the prevalence ...

INTRODUCTION: Despite extensive inpatient workup including telemetry monitoring, a significant proportion of stroke is classified as cryptogenic at hospital discharge. It is possible that a significant proportion of cryptogenic stroke is a result of intermittent atrial fibrillation (AF). Thirty-day cardiac event monitors (30-DEM) may increase the rate of AF detection ...

BACKGROUND AND PURPOSE: The clinical-diffusion mismatch (CDM) model has been proposed as a simpler tool than perfusion-diffusion mismatch (PDM) to select acute ischemic stroke patients for thrombolytic therapy. We hypothesized that in the 3- to 6-hour time window, the effect of tPA was significantly greater in patients with CDM than ...

OBJECTIVE: Currently, no practical biomarker is available for the diagnosis of acute ischemic stroke. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has being applied extensively to analyze large biomolecules such as proteins. The technique is likely to be of remarkable value as indicators of systemic processes such as atherosclerosis ...

Melatonin's neuroprotective action has been demonstrated in experimental models of brain ischaemia. The relationship between stroke and melatonin levels has been based on scarce and small sample size studies. In addition, the changes have not been correlated with the age of patients. We compared levels of nocturnal urinary melatonin and ...
