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.

Extreme heat spikes hospital intensive care cardiac arrest admissions

As daily temperatures climbed above 90 degrees Fahrenheit (F) across the U.S., so did the rate of out-of-hospital (OHCA) cardiac arrest admissions to hospitals intensive care units (ICUs); however, the heat didn't appear to impact the overall outcomes of people admitted for cardiac arrest during heat waves compared to other times, according to new, independent, preliminary research to be presented at the American Heart Association's Resuscitation Science Symposium 2026.

Platelet hyperactivity drives glioblastoma progression and deep vein thrombosis

New Cleveland Clinic research published in Cancer Cell shows that people with glioblastoma have more active platelets, which are cells involved in blood clotting. Platelets also communicate with other cells and can influence immune activity. The overactive platelets in people with glioblastoma slow the activity of cancer-fighting T cells, which can contribute to tumor growth and cancer progression.

Low vitamin B12 is linked to heart disease. Supplements tell a different story

A narrative review published in Nutrition Journal examines how vitamin B12 deficiency may contribute to cardiovascular disease through elevated homocysteine, endothelial dysfunction, oxidative stress and altered methylation. The authors found that B12 supplementation has not consistently prevented heart attacks or cardiovascular deaths in clinical trials, although combined B-vitamin therapy may modestly reduce stroke risk, particularly in populations without folic acid fortification.
