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.

Long-term diabetes changes red blood cells, increasing cardiovascular disease risk

The longer a person has type 2 diabetes, the greater the risk of cardiovascular disease. A new study from Karolinska Institutet, published in the journal Diabetes, shows that changes in red blood cells may be an important explanation, and identifies a specific molecule as a possible biomarker.

Federal hospital safety metric fails to accurately assess emergency stroke care

A new UCLA study reveals that a widely used federal hospital safety metric is fundamentally flawed when applied to emergency stroke care, potentially creating incentives that may discourage hospitals from performing lifesaving procedures for the sickest patients.

Scientists discover how stem cells navigate and repair brain damage after stroke

Some parts of our bodies bounce back from injury in fairly short order. The outer protective layer of the eye-called the cornea-can heal from minor scratches within a single day.

Physical activity shows comparable benefits to therapy for treating depression

Exercise may reduce symptoms of depression to a similar extent as psychological therapy, according to an updated Cochrane review. When compared with antidepressant medication, exercise also showed a similar effect, but the evidence was of low certainty.

Replenishing mitochondria significantly reduces chronic nerve pain, research shows

For millions living with nerve pain, even a light touch can feel unbearable. Scientists have long suspected that damaged nerve cells falter because their energy factories known as mitochondria don't function properly.

Light daily movement linked to lower mortality risk in people with CKM syndrome

Light intensity activities, like walking or household chores, were linked to a lower risk of death for people with cardiovascular-kidney-metabolic (CKM) syndrome, 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.
