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.

Mount Sinai researchers discover how Alzheimer's gene damages blood vessels

Mount Sinai researchers have identified how APOE4, the strongest genetic risk factor for Alzheimer's disease, damages the brain's blood vessels and promotes the buildup of abnormal proteins linked to neurodegenerative disease.

Kidney rhythm mismatch linked to dangerous nighttime high blood pressure

Most people's blood pressure falls by 10 to 20 per cent while they sleep, giving the heart and blood vessels a chance to recover. But for some people, that nighttime dip never happens.

Study finds oral hormone replacement therapy increases venous thromboembolism risk

Current use of oral menopausal hormone therapy (commonly known as hormone replacement therapy or HRT) is associated with an increased risk of blood clots in legs / lungs regardless of dose or treatment duration, finds a large Danish study published by The BMJ today.

Semaglutide’s heart benefits may extend beyond weight loss

Semaglutide is known to reduce the risk of serious heart disease. However, a new study published in the European Heart Journal today (Thursday) suggests that this effect cannot not be entirely explained by patients losing weight on the drug.

Nearly 60% of hypertension cases remain undetected in England

Researchers from Oxford Population Health analyzed clinic blood pressure measurements collected by Our Future Health, the UK's largest health research programme, from participants who enrolled between 2022 and 2025.

Transient ischemic attacks linked to increased long-term dementia risk

Having a transient ischemic attack (TIA) is associated with an increased risk of developing dementia, according to a new study published September 23, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Stroke rates nearly doubled among younger adults over three decades

Stroke is becoming more common among younger adults, according to a study published September 23, 2026, in Neurology, the medical journal of the American Academy of Neurology.

PsychAD studies map molecular mechanisms across major brain disorders

Research led by Mount Sinai scientists within the PsychAD Consortium, a large-scale, multidisciplinary initiative launched in 2019 with support from the National Institute on Aging (NIA), is featured in a landmark collection of nine papers published across the Nature family of journals that maps the molecular mechanisms underlying Alzheimer's disease, Parkinson's disease, schizophrenia, and other brain disorders.

Brain organoids reveal new clues for childhood epilepsy treatments

Tiny, year-old human brain organoids that mimic the brain of a newborn are providing new clues to potential treatments for a leading genetic cause of childhood epilepsy that typically manifests as the brain matures shortly after birth.

Genetic system converts scar-forming cells into neurons to restore movement after spinal cord injury

What if cells that form scars after a spinal cord injury could become part of the repair process? Researchers have developed a genetic system that converts certain scar-forming cells into neurons, improving movement in mice and rats with spinal cord injuries.

What links smoking, body fat, mental health, genes, and heart risk? Inflammation may be part of the answer

In a large UK Biobank study, higher levels of the chronic inflammation marker GlycA were associated with smaller heart chambers, thicker heart walls, impaired diastolic function, reduced stroke volume, and a 43% higher risk of major adverse cardiovascular events in the highest versus lowest GlycA group. Genetic susceptibility also modified the associations between environmental exposures, inflammation, and cardiovascular risk, while inflammatory proteins in the IL-1, TNF, and IL-6 pathways statistically mediated several of these associations.

Higher ultra-processed food intake linked to multiple health risks

A higher ultra processed food (UPF) intake is linked to a heightened risk of several major chronic health issues, such as digestive diseases, high blood pressure, and metabolic syndrome/diabetes, as well as death, finds a pooled data analysis of the available evidence, published in the open access journal Family Medicine and Community Health.

AI enhances handheld ultrasound images to detect carotid plaques

Handheld ultrasound devices' lower image quality can make small or faint carotid plaque hard to see. Researchers in Hunan Province, China, developed an artificial intelligence (AI) model that sharpens handheld ultrasound images after they are taken.

Core muscle activity rapidly regulates blood flow in the brain

Engaging core muscles - through movement, exercise, or even coughing - may be a key regulator of blood flow in the brain.

New international standard creates unified health data across Europe

Every breath we take contains tiny particles that are invisible to the naked eye and can harm our health. Air pollution alone contributes to heart disease, stroke, lung cancer, and other chronic illnesses.

Chronic stress and inflammation cause silent structural heart damage

Chronic stress from people's everyday lives may be causing lasting structural changes to the heart, harming health and reducing life expectancy.

Exercise-based cardiac rehabilitation offers lasting heart health benefits

Exercise-based cardiac rehabilitation reduces hospital admissions by a third and heart attack risk by more than a quarter, as well as remaining beneficial in the long term, a new Cochrane review finds.

ACC Latin America 2026 studies highlight sex and regional disparities in heart attack care

disparities in ST-segment elevation myocardial infarction (STEMI) management and outcomes across Latin America, focusing on women as a higher risk, yet underrepresented, patient group.

First US patient receives a mind-controlled bone-anchored bionic arm

A Chicago-area man is set to become the first person in the United States to receive a bionic arm connected directly to his bone, nerves and muscles - an advanced prosthesis designed to be controlled by his own neural signals and return sensory feedback in real time.
