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.

Long-term use of melatonin supplements linked to higher risk of heart failure and death

Long-term use of melatonin supplements, often used to promote sleep and address insomnia, was associated with a higher risk of heart failure diagnosis, heart failure hospitalization and death from any cause in chronic insomnia, according to a preliminary study to be presented at the American Heart Association's Scientific Sessions 2025.

Healthy lifestyle habits plus GLP-1 RA drugs can improve heart health of people with Type 2 diabetes

People with Type 2 diabetes who combined healthy lifestyle habits with GLP-1 receptor agonist (GLP-1 RA) medications had a greater reduction in risk of major adverse cardiovascular events, including heart attack, stroke or cardiovascular disease death, compared to people only taking the medication, according to a preliminary study to be presented at the American Heart Association's Scientific Sessions 2025.

Improving diagnosis, treatment and follow-up care for pulmonary embolism

Pulmonary embolism (PE), a type of blood clot in the lungs, sends more than half a million people to U.S. hospitals each year - and kills about one in five high-risk patients, according to the American Heart Association 2025 statistical update.

Common viruses sharply raise heart attack and stroke risk, major global review shows

In the largest synthesis to date, researchers reviewed 155 studies linking viral infections, including influenza, SARS-CoV-2, HIV, hepatitis C, and shingles, to increased risks of coronary heart disease, stroke, and heart failure. The findings highlight viral infection prevention and vaccination as underappreciated strategies for cardiovascular protection.

19 NCAA women's college basketball coaches join hands to support women’s heart health

Both on the court and off, cardiovascular disease is the leading killer of women in the United States, taking the lives of more than 440,000 women each year, according to the American Heart Association, a relentless force changing the future of health for everyone everywhere.

Oligodendrocyte progenitor cells promote blood vessel growth after stroke

Stroke is a leading cause of death and disability, affecting 1 in 4 people during their lifetime. Stroke happens when blood vessels in the brain get clogged or damaged, impairing blood flow and oxygen supply to the brain, which leads to death of neurons and other brain cells.

Football hits leave lasting brain changes

Recent MRI research reveals how repeated football head impacts reshape brain structures, offering insights into chronic traumatic encephalopathy (CTE) risk.

Scientists uncover why many cancer patients develop chemotherapy-induced neuropathy

Scientists at Wake Forest University School of Medicine, in collaboration with researchers at Weill Cornell Medicine, have made a breakthrough in understanding why many cancer patients develop nerve damage after chemotherapy.

Veterans with post-traumatic brain injury epilepsy more likely to have higher mortality rates

Military veterans who develop epilepsy after a traumatic brain injury may have a higher mortality rate in the following years than veterans who develop epilepsy with no previous traumatic brain injury, according to a study published on October 29, 2025, in Neurology®, the medical journal of the American Academy of Neurology.

New study sheds light on vision loss in idiopathic intracranial hypertension

If untreated, a disorder of high brain pressure called idiopathic intracranial hypertension can lead to vision loss. But this disorder can develop without noticeable symptoms, making it hard to catch.

Diets that harm the planet also raise the risk of cancer, heart disease, and diabetes

Diets that place greater pressure on the environment, high in meat and low in plant foods, were linked to higher risks of cancer, coronary heart disease, and type 2 diabetes in over 34,000 French adults. Sustainable, plant-rich diets were associated with better health and lower environmental impact.

Aligning your body clock may protect your heart and metabolism, says AHA

A new American Heart Association scientific statement highlights how maintaining circadian health through regular sleep, light exposure, meal timing, and exercise may reduce cardiometabolic disease risk. Disrupting these daily rhythms can impair glucose regulation, blood pressure, and cardiovascular function.

Computational model predicts the hemodynamic response of patients following atrial fibrillation

Atrial fibrillation (AFib) is a cardiac disorder in which the chambers of the heart beat rapidly and irregularly. It's the most common type of arrhythmia and the leading cardiac cause of stroke.

Two analgesic drugs may one day be repurposed as anti-tumor therapies

Peripheral afferent neurons - nerves that send signals from all areas of the body to the central nervous system (brain and spinal cord) - are known to infiltrate and grow within malignant bone tumors called osteosarcomas, often accompanied by severe pain.

29 Oct 2025

Some acute and chronic viral infections linked to increased risk of cardiovascular disease

In the weeks following a bout of influenza or COVID, the risk of heart attack or stroke may rise dramatically, and chronic infections such as HIV may increase the long-term risk of serious cardiovascular disease events, according to new, independent research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Heatwaves can significantly worsen obstructive sleep apnea

During heatwaves, there is an increase in the number of people suffering with obstructive sleep apnoea (OSA), according to a major study published today (Wednesday) in the European Respiratory Journal.

Standardized criteria show sustained reduction in hospital stay

A new approach to hospital discharges at UCLA reduced the time patients spent waiting to leave the hospital by nearly 50% for four common diagnoses and improved length of hospital stay by 2.5 days, according to a new pilot study at UCLA Health. Researchers say the standardized system could also serve as a case study for U.S. hospitals facing insufficient bed capacity and slow patient throughput.

AI-powered LifeClock forecasts diseases years before symptoms appear

Researchers have developed LifeClock, an AI-driven biological clock trained on over 24 million electronic health records to estimate biological age across the human lifespan. The model accurately predicts disease risk years in advance, revealing distinct developmental and aging processes.

Uncovering mechanisms of neuronal migration in the adult brain

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location.

Circadian rhythm disruptions may increase the risk of cardiovascular disease

As modern lifestyles increasingly challenge the body's natural circadian rhythm, the American Heart Association is spotlighting the potential health consequences of regular disruptions to our body's internal clock with a new scientific statement published today in its flagship journal Circulation.
