Immediate aspirin after mini-stroke substantially reduces risk of major stroke
Using aspirin urgently could substantially reduce the risk of major strokes in patients who have minor 'warning' events. Medical researchers say that immediate self-treatment when patients experience stroke-like symptoms would considerably reduce the risk of major stroke over the next few days.

Prevention is key to closing racial disparity gap in stroke
Middle aged African-Americans are more likely to die of stroke than are whites, not because of differences in care after stroke, but because blacks are having more strokes. Researchers suggest greater prevention efforts aimed at younger African-Americans are needed to raise awareness of early stroke risk and contributing factors.

Stroke damages blood-spinal cord barrier, researchers find
Researchers investigating the short and long-term effects of ischemic stroke in a rodent model have found that stroke can cause long-term damage to the blood-spinal cord barrier, which provides a specialized protective 'microenvironment' for neural cells in the spinal cord, creating a 'toxic environment' in the spinal cord that might leave stroke survivors susceptible to motor dysfunction and disease pathology.

Anemic adults may have a higher risk of death after stroke
, research indicates. Hemoglobin levels may also influence stroke deaths. Researchers suggest increased awareness and interventions are needed for stroke patients with anemia.

Hope for reversing stroke-induced long-term disability
Permanent brain damage from a stroke may be reversible thanks to a developing therapeutic technique, a study has found. The novel approach combines transplanted human stem cells with a special protein that the US Food and Drug Administration already approved for clinical studies in new stroke patients. The researchers say they are the first to use 3K3A-APC to produce neurons from human stem cells grafted into the stroke-damaged mouse brain.

New electrical stimulation therapy may improve hand function after stroke
A new technique uses a glove on the unaffected hand to send electrical stimulation to nerves in the stroke-affected hand. Researchers report that the best improvement was noted in patients who had moderate hand impairment from their stroke less than two years earlier. The study also demonstrated that stroke survivors can effectively use technology for self-administered therapy at home.

Transplanted neurons incorporated into a stroke-injured rat brain
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responde d correctly when the rat’s muzzle and paws were touched.

Receiving a clot-buster drug before reaching the hospital may reduce stroke disability
A preliminary study shows that giving a clot-busting drug in a mobile stroke unit ambulance may lead to less disability after stroke, compared to when the clot-buster is given after reaching the hospital. The study suggests that ambulances with the personnel and equipment capable of diagnosing ischemic stroke may be worth the extra cost, due to the decrease in patient disability afterward.

Alpha-1 antitrypsin dysfunction and large artery stroke Biochemistry
Ischemic stroke—that is, cerebral infarction causing stroke symptoms—is pathophysiologically and phenotypically heterogeneous. To address this heterogeneity, investigators have often chosen to study the genetics of ischemic stroke according to its less-heterogeneous phenotypes. Many systems have been developed and deployed for classifying ischemic stroke into subphenotypes. In pursuit of gene discovery,...

Stroke prevention may also reduce dementia
Ontario ' s stroke prevention strategy appears to have had an unexpected, beneficial side effect: a reduction also in the incidence of dementia among older seniors. A new paper is the first to look at the demographics of both stroke and dementia across Ontario since the province pioneered Canada ' s first stroke prevention strategy in 2000.

Study results show reduction in disability from stroke up to 24 hours of onset
Results from a stroke trial provide compelling evidence that selected patients suffering a major ischemic stroke recovered significantly better with mechanical retrieval of the blood clot with medical therapy compared with medical therapy alone when initiated up to 24 hours of the stroke.

Sung melody enhances verbal learning and recall after stroke
Abstract Coupling novel verbal material with a musical melody can potentially aid in its learning and recall in healthy subjects, but this has never been systematically studied in stroke patients with cognitive deficits. In a counterbalanced design, we presented novel verbal material (short narrative stories) in both spoken and sung formats to stroke patients at the acute poststroke stage and 6 months poststroke. The task comprised three learning trials and a delayed recall trial. Memory performance on the spoken and sung tasks did not differ at the acute stage, whereas sung stories were learned and recalled significantly ...

Prognostic Factors of Functional Recovery from Left Hemispheric Stroke.
This study aimed to reveal the prognostic variables that relate to functional recovery in stroke patients with a left-sided hemispheric lesion during 6 months of follow-up. Data from 167 left-sided and 183 right-sided hemispheric strokes were reviewed retrospectively. Outcomes in this study included walking capacity and functional recovery, assessed by the modified Rankin Scale (mRS). In order to obtain independent predictive variables, this study used the step-backward method of multivariable regression analysis of parameters. The final model demonstrated that motor function of the hemiparetic leg was the strongest indepe...

Bio-inspired upper limb soft exoskeleton to reduce stroke-induced complications
Stroke has become the leading cause of disability and the second-leading cause of mortality worldwide. Dyskinesia complications are the major reason of these high death and disability rates. As a tool for rapid motion function recovery in stroke patients, exoskeleton robots can reduce complications and thereby decrease stroke mortality rates. However, existing exoskeleton robots interfere with the wearer ’s natural motion and damage joints and muscles due to poor human-machine coupling. In this paper, a novel ergonomic soft bionic exoskeleton robot with 7  degrees of freedom was proposed to address these problems...

Development and flight performance of a biologically-inspired tailless flapping-wing micro air vehicle with wing stroke plane modulation
The tailless flapping-wing micro air vehicle (FW-MAV) is one of the most challenging problems in flapping-wing design due to its lack of tail for inherent flight stability. It must be designed in such a way that it can produce proper augmented control moments modulated by a closed-loop attitude controller for active stabilization. We propose a tailless FW-MAV with a wing stroke plane modulation mechanism, namely NUS-Roboticbird, which maneuvers by only using its flapping wings for both propulsion and attitude control. The flying vehicle has four wings comprised by two pairs, and each pair of wings and its stroke plan...
