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.

New research reveals persistent racial gap in stroke survival rates

Overall rates of long-term survival following stroke are improving, but Black individuals experience worse long-term outcomes compared to white individuals, according to University of Cincinnati research published online July 15 in Neurology, the medical journal of the American Academy of Neurology.

NIH grant supports advancement in cognitive screening after devastating type of stroke

The Associate Dean of Research at the University of Tennessee Health Science Center's College of Nursing has received a two-year, $421,188 grant from the National Institutes of Health (NIH) to improve cognitive screening in people who suffer from a devastating type of stroke called aneurysmal subarachnoid hemorrhage (aSAH).

Mechanism behind propofol-induced unconsciousness revealed

There are many drugs that anesthesiologists can use to induce unconsciousness in patients. Exactly how these drugs cause the brain to lose consciousness has been a longstanding question, but MIT neuroscientists have now answered that question for one commonly used anesthesia drug.

Precise brain imaging method reveals origins of creativity

Have you ever had the solution for a tough problem suddenly hit you when you're thinking about something entirely different? Creative thought is a hallmark of humanity, but it's an ephemeral, almost paradoxical ability, striking unexpectedly when it's not sought out.

Long-term, 30-year CVD risk may help inform therapy for stage 1 hypertension

A comparison of two risk prediction tools used to calculate an individual's risk of developing cardiovascular disease (CVD) suggests that the long-term, 30-year risk should be considered in addition to the short-term, 10-year risk to help inform when to begin medication therapy for stage 1 hypertension, or high blood pressure, according to new research published today in Hypertension, an American Heart Association journal.

Gene editing silences mutant microRNA, restores hearing in adult mice

Researchers have used gene editing to restore hearing in adult mice with a type of inherited hearing loss. They showed that shutting down a damaged copy of a gene called a microRNA (miRNA) enabled the animals to regain hearing. The approach by a research team supported by the National Institutes of Health (NIH), reported in Science Translational Medicine, may eventually lead to potential treatments for inherited hearing loss in people.

Four-year diabetes delay reduces death and complications in prediabetic patients

Individuals diagnosed with prediabetes can reduce their long-term risk of death and diabetes-related health complications if they delay the onset of diabetes for just four years through diet and exercise. Guangwei Li of the China-Japan Friendship Hospital and colleagues report these findings in a new study published July 9th in the open-access journal PLOS Medicine.
