Stroke News and Research

RSS

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.

TXA reduces the need for blood transfusion in patients undergoing high-risk non-cardiac surgery

When hospitals were randomly assigned to treat patients undergoing higher-risk non-cardiac surgery with tranexamic acid (TXA) or a placebo, patients who received TXA needed significantly fewer blood transfusions and saw no increase in potentially life-threatening blood clots (thrombosis) after 90 days of follow-up, according to research presented at the 67th American Society of Hematology (ASH) Annual Meeting and Exposition.

Novel wireless device uses light to send information directly to the brain

In a new leap for neurobiology and bioelectronics, Northwestern University scientists have developed a wireless device that uses light to send information directly to the brain - bypassing the body's natural sensory pathways.

AI model could help radiologists identify brain abnormalities in MRI scans

A new AI model could help radiologists identify brain abnormalities in MRI scans for all conditions including stroke, multiple sclerosis and brain tumors.

Breakthrough in imaging speed moves portable stroke diagnosis closer to reality

When someone walks into an emergency room with symptoms of a stroke, every second matters. But today, diagnosing the type of stroke, the life-or-death distinction between a clot and a bleed, requires large, stationary machines like CT scanners that may not be available everywhere.

Long-term air pollution exposure linked to more advanced coronary artery disease

Long-term exposure to common air pollutants is associated with more advanced coronary artery disease-with notable differences between women and men-according to a large-scale study of more than 11,000 adults being presented today at the annual meeting of the Radiological Society of North America (RSNA).

Study finds major gaps in cholesterol management among adults with cardiovascular disease

The Family Heart Foundation, a leading research and advocacy organization, published new research in the American Journal of Preventive Cardiology revealing significant gaps in cholesterol management during 2022-23 among U.S. adults with atherosclerotic cardiovascular disease (ASCVD).

Recurrent strokes can be avoided with optimal prevention and follow-up

Patients who have had a stroke are prescribed medication to prevent new strokes. Nevertheless, fewer than half achieve the optimal treatment targets.

Protein tied to ALS and dementia plays a role in regulating DNA mismatch repair

New Houston Methodist research has revealed that a protein associated with neurodegenerative diseases such as dementia and amyotrophic lateral sclerosis (ALS) also plays a role in regulating DNA mismatch repair, a process essential for replicating genetic information and cell health.

Untreated restless legs syndrome may increase Parkinson's disease risk

Restless legs syndrome (RLS) is a common neurological sleep disorder characterized by an uncontrollable urge to move the legs, often worsening at night.

New evidence supports ablation for high-risk patients with AFib and sleep apnea

Obstructive sleep apnea and atrial fibrillation are two conditions that share a potentially deadly link. Having one increases the odds of developing the other, and together, the breathing difficulties of sleep apnea combined with the irregular heartbeat of atrial fibrillation (AFib) can result in life-threatening cardiovascular risks.

New 10-minute scan shows hidden cause of high blood pressure

A speedy new scan could improve how millions of people with high blood pressure are treated, suggests a new study led by UCL (University College London) researchers.

White matter alterations connect coronary artery disease to cognitive decline

Individuals with coronary artery disease (CAD) - a constricting or blocking of blood vessels feeding the heart - face increased risks of strokes, cognitive impairment and dementia. However, the link between CAD and cognitive function is not fully understood.

New analysis shows one in two people in the U.S. live with neurological conditions

One in two people in the United States, just over half of the population, is affected by a neurological disease or disorder, according to a new systematic analysis by the American Academy of Neurology and the Institute for Health Metrics and Evaluation published on November 24, 2025, in the journal JAMA Neurology.

Does coffee truly boost memory and focus or is it all hype?

Coffee’s bioactive compounds, especially caffeine, show potential cognitive, neuroprotective, and neuroplasticity benefits across animal and human studies. However, most findings are observational, mechanisms remain uncertain, and optimal intake is still unclear.
