Cerebrovascular accident (CVA) is a common, devastating neurological complication of sickle cell disorder (SCD) with a high recurrent and mortality rate. The Stroke Prevention Trial in Sickle Cell Anaemia study (STOP) recommends routine screening with transcranial Doppler ultrasonography in children aged two to sixteen years with SCD. The present study assessed cerebral blood flow velocities of children with SCD in accordance with the recommendation of routine screening by the STOP study. METHODS: Transcranial Doppler ultrasonography was done for children with SCD that attended Sickle Cell Foundation, Nigeria between July and November 2015...

Central post-stroke pain (CPSP) can occur as a result of a cerebrovascular accident in the ventral posterolateral nucleus (VPL) of the thalamus. Developing therapeutic interventions for CPSP is difficult because its pathophysiology is unclear. Here we developed and characterized a macaque model of CPSP. The location of the VPL was determined by magnetic resonance imaging (MRI) and extracellular recording of neuronal activity during tactile stimulation, after which a hemorrhagic lesion was induced by injecting collagenase type IV...

BACKGROUND: The CHADS2 score has mainly been used to predict the likelihood of cerebrovascular accidents in patients with atrial fibrillation. However, increasing attention is being paid to this scoring system for risk stratification of patients with coronary artery disease. We investigated the value of the CHADS2 score in predicting cardiovascular/cerebrovascular events in coronary artery disease patients without atrial fibrillation. METHODS AND RESULTS: This was a multicenter, observational cohort study...

BACKGROUND: Stroke risk is a significant concern in patients with atrial fibrillation (AF). Low stroke risk patients (CHADS2 VASc 0-2) are often treated long-term with aspirin after catheter ablation. Defining the long-term risks versus benefits of aspirin therapy, after an ablation, is essential to validate this common clinical approach. METHODS: A total of 4,124 AF ablation patients undergoing their index ablation were included in this retrospective observational study...

OBJECTIVE: The electromyographic bridge (EMGB) detects surface electromyographic signals from a non-paretic limb. It then generates electric pulse trains according to the electromyographic time domain features, which can be used to stimulate a paralysed or paretic limb in real time. This strategy can be used for the contralateral control of neuromuscular electrical stimulation (NMES) to improve motor function after stroke. The aim of this study was to compare the treat-ment effects of EMGB vs cyclic NMES on wrist and finger impairments in subacute stroke patients...

A 4-year-old female patient presents to the pediatric emergency department with acute onset of ataxia and occipital headache. Initial investigation, including computed tomography imaging, failed to demonstrate any focal neurologic lesion. Subsequent studies, however, reveal an acute thrombosis of the superior cerebellar artery. Further work up identified the likely causative factor to be a heterozygous mutation at the methylene tetrahydrofolate reductase gene. In this case report, we will discuss the work-up of pediatric ataxia, the evaluation and management of cerebrovascular accidents in children, and the association between stroke and mutation of the methylene tetrahydrofolate reductase gene...

BACKGROUND AND OBJECTIVE: Cerebral vascular accident (CVA), also known as stroke, is an important health problem worldwide and it affects 16 million people worldwide every year. About 30% of those that have a stroke die and 40% remain with serious physical limitations. However, recovery in the damaged region is possible if treatment is performed immediately. In the case of a stroke, Computed Tomography (CT) is the most appropriate technique to confirm the occurrence and to investigate its extent and severity...

The benefits of β-blockers in patients with heart failure (HF) with reduced ejection fraction (HFrEF) and atrial fibrillation (AF) are controversial. The Gulf Survey of Atrial Fibrillation Events was a prospective, multinational, observational registry of consecutive patients with AF recruited from the emergency department (ED). We studied the incidence of 6- and 12-month mortality, hospitalization for HF or AF, and stroke/transient ischemic attacks (TIAs) in patients with HFrEF, in relation to β-blockers on discharge from the ED or the subsequent hospital stay...

Fairly limited data reported the incidence and risk of cerebrovascular accident (CVA) in autosomal dominant polycystic kidney disease (ADPKD). Additionally, little is known regarding the therapeutic impact of renin-angiotensin-aldosterone system (RAAS) blockade and statin on reducing the occurrence of CVA in ADPKD. We utilized the data from Taiwan National Health Insurance Research Database (NHIRD) to perform a population-based cohort study (1997-2013). A total of 2,647 patients with ADPKD were selected from 1,000,000 general population after excluding patients with age<18, renal replacement therapy and concomitant diagnosis of CVA...

REVIEW
John Amerena, Daryl Ridley
Cerebrovascular accidents related to atrial fibrillation (AF) are potentially preventable with anticoagulation. Until recently, warfarin was the only proven anticoagulant to be effective in stroke prevention, however the novel, direct acting oral anticoagulants (DOACs) are now available, triggering a paradigm shift in treatment philosophy. Today, physicians need to consider in which patients anticoagulation should not be used rather than, as in the past, deciding in which patients it should be used. Although warfarin will continue to have a place in managing some patients with AF, in the future, the DOACs should be the predominant therapy for stroke prevention in patients with non-valvular AF...
