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.

Air pollution may trigger arrhythmias in healthy adolescents

Breathing particulate matter (i.e., tiny particles suspended in the air) air pollution may trigger irregular heart rhythms (arrhythmias) in healthy teenagers, 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.

Every step counts to lower cancer and cardiovascular disease risk

In a recent study published in JAMA Internal Medicine, researchers in Australia, Denmark, and the United States pursued evidence of an association between daily walking and its intensity with the risk of cancer and cardiovascular diseases (CVDs) in a cohort of 78,500 individuals aged 40 to 79 years in the United Kingdom (UK).

Treating the cerebrospinal fluid to protect the brain from chemotherapy's toxic effects

Up to three quarters of patients receiving cancer chemotherapy suffer from "chemo brain" - a long-term side effect that makes it harder to remember things, maintain attention, and learn new information. When it strikes children, whose brains are still developing, their schoolwork and self-esteem may suffer.

Pollutant particles in the air trigger lung cancer in non-smokers

A new mechanism has been identified through which very small pollutant particles in the air may trigger lung cancer in people who have never smoked, paving the way to new prevention approaches and development of therapies, according to late-breaking data [to be] reported at the ESMO Congress 2022 by scientists of the Francis Crick Institute and University College London, funded by Cancer Research UK. The particles, which are typically found in vehicle exhaust and smoke from fossil fuels, are associated with non-small cell lung cancer (NSCLC) risk, accounting for over 250,000 lung cancer deaths globally per year.

Research highlights the serious health implications of young-onset type 2 diabetes

Men and women who are diagnosed with type 2 diabetes (T2D) aged 40 or younger are far more likely to develop cardiovascular disease (CVD) and die prematurely than those under 40 in the general population, according to new research to be presented at this year's European Association for the Study of Diabetes (EASD) Annual Meeting in Stockholm, Sweden (19-23 Sept).

High blood pressure may cause bones to age faster

When high blood pressure was induced in young mice, they had bone loss and osteoporosis-related bone damage comparable to older mice, according to new research presented today at the American Heart Association's Hypertension Scientific Sessions 2022 conference, held Sept. 7-10, 2022, in San Diego.

New research focuses on restoring movement after spinal cord injury

People with spinal cord injuries often experience life-long movement impairment or paralysis, for which there is no cure. When coupled with rehabilitative exercise, electrical spinal cord stimulation can help restore some movement, though the mechanisms of how the nerves in the spinal cord recover are unknown.
