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.

Early life adversity and high levels of FKBP5 protein amplify anxiety-like behavior

Polygenic risk scores based on entire genome sequence may reliably predict heart disease

Specialized risk scores derived from testing that calculates the cumulative effect of an individual's entire DNA sequence, the genome, may reliably predict heart disease in people who have not yet had a heart attack, according to new research in Circulation: Genomic and Precision Medicine, an American Heart Association journal.

Opioid epidemic increases proportion of hearts transplanted from overdose death donors

The confluence of two major health crises—the opioid epidemic and organ shortage—has moved surgeons to consider transplanting organs deemed as less than "perfect" in an effort to expand the donor pool and save more lives, according to research published online today in The Annals of Thoracic Surgery, published by Elsevier.

Analysis: Why Alexa’s bedside manner is bad for health care

Amazon has opened a new health care frontier: Now Alexa can be used to transmit patient data. Using this new feature — which Amazon labeled as a "skill" — a company named Livongo will allow diabetes patients — which it calls "members" — to use the device to "query their last blood sugar reading, blood sugar measurement trends, and receive insights and Health Nudges that are personalized to them."

Study identifies brain hemorrhage patients most likely to have treatable underlying condition

When blood vessels in the brain rupture, or hemorrhage, and cause a stroke, large areas of the brain can be permanently damaged. Depending on the cause, some brain hemorrhages may hide underlying lesions that can be treated with surgery, embolization, radiation, or other treatments.

People living with HIV have increased risk for heart diseases and face health challenges

Effective antiretroviral therapy has changed the human immunodeficiency virus (HIV) from a progressive, fatal disease to a chronic, manageable condition that is associated with higher rates of heart attacks, strokes, heart failure, sudden cardiac deaths, and other diseases compared to people without HIV, according to a new scientific statement from the American Heart Association published in the Association journal Circulation.

Astrocytes protect neurons from damaging side effects of overactivity

Astrocytes are overtaxed neurons' pit crew. The brain cells collect damaged lipids secreted by hyperactive neurons, then recycle those toxic molecules into energy, researchers at the Howard Hughes Medical Institute's Janelia Research Campus report May 23, 2019, in the journal Cell.
