For the first time, air pollution emerges as a leading risk factor for stroke worldwide
Air pollution -- including environmental and household air pollution -- has emerged as a leading risk factor for stroke worldwide, associated with about a third of the global burden of stroke in 2013, according to a new study.

New imaging method may predict risk of post-treatment brain bleeding after stroke
In a study of stroke patients, investigators confirmed through MRI brain scans that there was an association between the extent of disruption to the brain's protective blood-brain barrier and the severity of bleeding following invasive stroke therapy. The results of the National Institutes of Health-funded study were published in Neurology.

New neuroendovascular technique shows promise in stroke patients with large-vessel clots
Scientists report promising 90-day outcomes for stroke patients with large-vessel clots who underwent thrombectomy or clot removal using the direct-aspiration, first pass technique (ADAPT). Approximately 58 percent of stroke patients with a large-vessel clot removed using the technique achieved a good outcome at 90 days, defined as a Modified Rankin Score (mRS) of 0 to 2.

In predicting a stroke's toll, location matters, but so do connections
Each year, roughly 666,000 Americans survive a stroke, and for them, the aftermath can be hard to predict. Some stroke patients have difficulty speaking or grasp for words that do not come. Some suffer problems with vision, balance or mobility. Some are addled by attention, memory and other cognitive...

Connectivity changes predict deficit after stroke Neuroscience
Deficits following stroke are classically attributed to focal damage, but recent evidence suggests a key role of distributed brain network disruption. We measured resting functional connectivity (FC), lesion topography, and behavior in multiple domains (attention, visual memory, verbal memory, language, motor, and visual) in a cohort of 132 stroke patients,...

Insomnia? Oversleeping? Both may increase your risk of stroke
There is growing evidence that sleep disorders like insomnia and sleep apnea are related to stroke risk and recovery from stroke, according to a recent literature review.

Alcohol-related hospitalization associated with doubled stroke risk in atrial fibrillation
Alcohol-related hospitalization is associated with a doubled risk of ischemic stroke risk in patients with non-valvular atrial fibrillation, according to a new study. The observational study was conducted in more than 25,000 non-valvular atrial fibrillation patients at low risk of stroke.

Women and minorities are less likely to get key stroke treatment, even when they're eligible, study says
If you ’re having an ischemic stroke, it’s crucial that you get to a hospital fast so you can be treated with a clot-busting medicine. And to improve your odds of getting that medicine, it helps to be a white man.A new analysis of more than 60,000 stroke patients from around the country found that...

Time window to help people who have had a stroke longer than previously shown
Time is of the essence when getting people stricken with acute ischemic strokes to treatment. Current professional guidelines recommend that stent retrievers be used to remove blood clots from stroke patients within six hours for people to benefit. But new research finds that the procedure has benefits for people up to 7.3 hours following the onset of a stroke.

PFO closure is more effective than medical management in preventing recurrent stroke, long-term study results show
Percutaneously closing a patent foramen ovale (PFO) using the Amplatzer PFO Occluder was superior to medical management in the prevention of recurrent ischemic stroke in patients who previously had a cryptogenic stroke, final results from the RESPECT trial found.

Generation X at greater risk of stroke than baby boomers
Older baby boomers —those born between 1945 and 1954—are the “stroke-healthiest generation,” according to a new study that found the lowest incidence of ischemic stroke in this age group within the past 20 years. In contrast, the rate of stroke more than doubled in Generation X, people born between 1965 and 19 74, during the same time period.

Stroke patients in UK 'missing out on treatment for brain clots'
Thousands of patients not being offered procedure that can dramatically reduce disability after a stroke, research suggestsThousands of stroke patients in the UK may be missing out on a treatment that involves physically unplugging blood vessels in the brain, research suggests.Scientists estimate that about 9,000 patients with blood clots in the brain – a tenth of the total – could benefit from mechanical thrombectomy (MT) each year. Currently, fewer than 600 patients a year undergo the procedure.Continue reading...

How physical exercise aids in stroke recovery
Mice that had free-access to a running wheel were able to maintain ocular dominance plasticity after suffering a stroke, compared to those that didn ' t, new research shows. These exciting observations have the potential to provide a simple but effective method to protect and rehabilitate patients that are prone to, or have already suffered, a stroke.

Benzodiazepines, related drugs increase stroke risk among persons with Alzheimer ' s disease
The use of benzodiazepines and benzodiazepine-like drugs was associated with a 20 per cent increased risk of stroke among persons with Alzheimer ’s disease, shows a recent study. Benzodiazepines were associated with a similar risk of stroke as benzodiazepine-like drugs.

In search of the stroke detector
Up to 50% of stroke diagnoses are inaccurate. What if a small biosensor could do the job precisely? Robert McCrum, who survived a ‘brain attack’ 22 years ago, traces one team’s long journey to a breakthroughStroke, or “brain attack”, is the third biggest killer in the western world, after cancer and heart failure. The life-changing effects associated with this simple, Anglo-Saxon word are readily explained: a stroke occurs when the blood supply to the brain is disrupted by a blood vessel either bursting or blocking, so that the part of the brain supplied by this blood vessel dies.The brain is a much more com...
