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.

Unlocking neuroglia’s potential to halt neurodegeneration and restore brain homeostasis

In a revealing Genomic Press Interview published today in Brain Medicine, Professor Alexei Verkhratsky dismantles decades of neuroscience orthodoxy with discoveries that position neuroglia as active architects of brain function rather than passive cellular bystanders.

New research reveals why blood clotting malfunctions in inflammatory bowel disease

Inflammatory bowel disease, in which the immune system attacks the gut, is a painful chronic condition that affects three million Americans. Rates of IBD are rising, and there's currently no cure. IBD can also be deadly: up to 8% of people with the disease develop blood clots, which can lead to heart attack and stroke.

Fat location, not BMI, drives heart ageing risk in men and women

Researchers using UK Biobank imaging data found that where fat is stored in the body, not just how much, determines cardiovascular ageing. Visceral, liver, and muscle fat accelerate ageing, while gynoid fat protects women before menopause.

History of traumatic brain injury tied to greater chance of malignant brain tumors

New research led by investigators at Mass General Brigham suggests a link between a history of traumatic brain injury (TBI) and risk of developing a malignant brain tumor.

New study reveals long road to seizure control for people with focal epilepsy

Antiseizure medications help the majority of people with focal epilepsy, a common form of the neurological disorder.

How a single gene reshapes pain perception through polyamine signaling

Researchers have identified SLC45A4 as a neuronal polyamine transporter genetically linked to human chronic pain. Loss of this gene in mice disrupts polyamine balance, alters spinal GABA levels, and reduces heat and tonic pain sensitivity.

Can AI help you eat healthier?

Researchers developed and validated an AI-based nutrition recommendation system (AINR) that generates weekly Mediterranean meal plans tailored to individual needs and dietary restrictions. Tested on 4,000 simulated users, the system achieved high accuracy in calorie and nutrient targets but struggled with profiles involving milk and nut allergies.

Postmenopausal women with stroke history can safely use vaginal estrogen

Using vaginal estrogen tablets was not associated with an increased risk of recurrent ischemic stroke among postmenopausal women in a registry in Denmark, according to research published today in Stroke, the peer-reviewed scientific journal of the American Stroke Association, a division of the American Heart Association.

High-salt diet linked to brain inflammation that raises blood pressure

A new study finds that a high-salt diet triggers brain inflammation that drives up blood pressure.

Metabolic syndrome linked to higher risk of Parkinson's disease

Having a larger waistline, high blood pressure and other risk factors that make up metabolic syndrome is associated with an increased risk of Parkinson's disease, according to a study published on August 20, 2025, in Neurology, the medical journal of the American Academy of Neurology.

Elevated TMAO levels linked to higher risk of abdominal aortic aneurysms

Cleveland Clinic researchers have discovered a connection between elevated blood levels of TMAO (trimethylamine N-oxide) - a byproduct of gut bacteria digestion of nutrients found in red meat and other animal products - and a higher risk of abdominal aortic aneurysms.

Cardiovascular health declines in older adults with heart conditions

U.S. adults, ages 65 and older, with high blood pressure, heart failure or stroke had significant declines in cardiovascular health, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Impaired blood flow alters immunity and fuels tumor progression

Cutting off blood flow can prematurely age the bone marrow, weakening the immune system's ability to fight cancer, according to a new study from NYU Langone Health.

Community exercise helps older adults maintain fitness and strength

Older adults who regularly participated in a community-based exercise program were able to slow - and in many cases reverse - declines in cardio fitness and strength that naturally come with age, a new McMaster study shows.

FAST walk shows promise in improving gait for chronic stroke patients

Stroke remains one of the leading causes of long-term disability worldwide, affecting millions each year.

Researchers develop a 3D-bioprinted in vitro model of stenotic brain blood vessels

Cerebrovascular diseases such as atherosclerosis and stroke remain a major cause of morbidity and mortality worldwide.

Aggressive blood pressure management offers greater health benefits

Research led by investigators at Mass General Brigham suggests that the health benefits of more aggressive blood pressure control outweigh concerns about overtreating people with high blood pressure readings. Results of the simulation study are published in Annals of Internal Medicine.

Study links COVID-19 infection to accelerated blood vessel aging in women

A Covid infection, particularly in women, may lead to blood vessels aging around five years, according to research published in the European Heart Journal on 18th August, 2025.

Newly discovered biological pathway explains clotting risk in people with type 2 diabetes

New research from the Charles Perkins Centre at the University of Sydney has uncovered a new biological pathway that may help explain why people with type 2 diabetes are more prone to developing dangerous blood clots, potentially paving the way for future treatments that reduce their cardiovascular risk.

Leg movement variability provides reliable marker of dystonia in pediatric cerebral palsy

Cerebral palsy affects around one in 345 children in the U.S., and more than half of them experience a problem called dystonia - involuntary and often painful muscle contractions, most commonly in the legs, that lead to abnormal movement and postures and make regular activities such as walking difficult.
