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.

Scientists decode inner speech from brain activity with high accuracy

Scientists have pinpointed brain activity related to inner speech-the silent monologue in people's heads-and successfully decoded it on command with up to 74% accuracy.

New 2025 guidelines focus on early intervention and lifestyle to manage high blood pressure

Preventing and managing high blood pressure with healthy lifestyle behaviors, such as following a heart-healthy diet including reducing salt intake, staying physically active, maintaining a healthy weight and managing stress—combined with early treatment with medication to lower blood pressure if necessary—are recommended to reduce the risk of heart attack, stroke, heart failure, kidney disease, cognitive decline and dementia, according to a new clinical guideline published today in the American Heart Association's peer-reviewed journals Circulation and Hypertension, and in JACC, the flagship journal of the American College of Cardiology.

New study explains why neuroblastoma returns years later

Cancer is the leading cause of disease-related death in childhood. This is in part due to cancer-associated genes called oncogenes that can be found far from chromosomes in cell nuclei on ring-shaped DNA inside tumor cells.

Study identifies why stroke impairs ability to use word meanings in reading

A key discovery about the impact of stroke on a person's ability to read reveals why a deficit occurs – a finding that presents a possible opportunity for new therapeutic strategies to help people recover one of the most important life skills.

Pandemic left measurable changes in teen brains, hormones, and immunity

Adolescents assessed after COVID-19 lockdowns showed lower daily cortisol, higher inflammation, and reduced prefrontal cortex activity compared to matched pre-pandemic peers, suggesting widespread stress-related biological changes. These alterations mirror patterns seen after prolonged early-life stress, raising concerns about long-term health risks.

Extreme heat and humidity greatly increase heart emergency risk

Extreme heat can be hard on your heart. As temperatures rise, the heart pumps faster to move blood toward the skin to cool the body.

New computational tool enhances CAR T cell therapy for hard-to-treat cancers

A computational approach by St. Jude Children's Research Hospital scientists promises to make designing T cell-based immunotherapies that target two cancer-related antigens at the same time far easier and faster.

New computer model provides detailed look at mouse brain vasculature

Healthy brain function relies on a steady supply of blood. Disruptions in blood flow are linked to major neurological conditions like stroke, Alzheimer's disease (AD), and traumatic brain injuries. But understanding how the brain fine-tunes this flow – especially across its smallest blood vessels – remains a challenge.

Long COVID linked to lasting financial hardship and work disruption

While the economic impact of the COVID-19 pandemic continues to be widely studied and debated, the financial toll of the COVID-19 pandemic for individual patients is less understood.

New research highlights combined impact of genes and lifestyle on dilated cardiomyopathy

An international team, led by scientists from the Victor Chang Cardiac Research Institute has studied around 3000 people affected by the heart disease dilated cardiomyopathy (DCM) – a driver of heart failure and sudden cardiac arrest.

Breakthrough approaches enhance RNA delivery while minimizing inflammation

Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of RNA delivery.

Fetal procedure dramatically reduces mortality in high-risk Vein of Galen Malformation cases

Building upon the success of the first in utero brain surgery for Vein of Galen Malformation (VOGM) reported in 2023, new data published today in JAMA provides further evidence for the potential use of fetal embolization for this condition.

Stalking and restraining orders linked to higher risk of heart disease in women

Women who reported having been stalked or obtained a restraining order were each more likely to experience a heart attack and/or stroke in later years compared to those who did not, according to new research published today in the American Heart Association's flagship journal Circulation.

Epigenetic breakthrough: $200 blood test spots diabetes heart risk better than standard tools

Researchers have developed a blood-based DNA methylation risk score that predicts first macrovascular events in newly diagnosed type 2 diabetes patients more accurately than current cardiovascular risk tools. The score, when combined with clinical factors, could help target early prevention in high-risk individuals.

Ancient shankh blowing practice found to improve sleep and alertness in OSA patients

People who practised blowing through a conch shell regularly for six months experienced a reduction in their symptoms of obstructive sleep apnoea (OSA), according to a small randomised controlled trial published today (Monday) in ERJ Open Research.

Vital role of physical activity in early type 2 diabetes care

New research to be presented at this year's Annual Meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria (15-19 September) shows, among people recently diagnosed with type with type 2 diabetes and no previous cardiovascular disease, a clear association exists between a person's self-reported physical activity and their risk of all-cause mortality and major adverse cardiac events (MACE), that include heart attacks and strokes.
