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.

Scientists discover two ways to preserve diseased upper motor neurons in ALS

Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, and they degenerate in ALS.

Realistic model explores new treatments for brain tumors

Until now, the use of models to study the barrier that differentiates the circulatory and nervous systems has been either limited or extremely complex. ETH Zurich researchers have created a more accurate model that can also be used to effectively investigate new treatments for brain tumors.

The brain prepares skilled movements by 'zipping and unzipping' information

The human brain prepares skilled movements such as playing the piano, competing in athletics, or dancing by 'zipping and unzipping' information about the timing and order of movements ahead of the action being performed, a new study reveals.

Highlighting the potential of new techniques to study mental disorders

Researchers investigating the fundamental brain mechanics of autism spectrum disorder have discovered that a gene mutation known to be connected with the illness causes considerably more overstimulation of brain cells than in neuronal cells without the mutation.

Revitalized immune cells improve waste removal from the brain

Damaged protein clusters in the brain are a hallmark of many neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and others. Although they have made significant efforts, scientists have only partially succeeded in finding treatments for these conditions by removing these toxic clusters.

Simple blood test helps identify patients developing neurotoxic side effects

The treatment of various tumors has been transformed by cell-based immunotherapy, often known as CAR-T cell therapy. To target and combat specific forms of leukemia and lymphoma, the treatment employs genetically engineered T cells.

Scientists discover latent stem cells that respond to injury in the central nervous system of mice

Scientists at the Francis Crick Institute have identified a group of latent stem cells that respond to injury in the central nervous system of mice. If a similar type of cell exists in humans, they could offer a new therapeutic approach to treat brain and spinal cord injuries.

Comprehensive review provides insights on salt-reducing technologies in food production

Sodium is an essential micronutrient, but the amount we need is small. Three slices of bread or one teaspoon of table salt will do it, and chances are your daily sodium intake is far greater.

A mitochondrial uncoupler prevents sarcopenic obesity in elderly mice

A recently discovered chemical compound helped elderly mice with obesity lose fat and weight, add muscle and strength, reduce age-related inflammation and increase physical activity, a new study shows.

Breakthrough discovery provides a desirable drug target to tackle metabolic diseases

In a breakthrough discovery, scientists from The University of Texas Health Science Center at San Antonio today reported that inhibiting a liver enzyme in obese mice decreased the rodents' appetite, increased energy expenditure in adipose (fat) tissues and resulted in weight loss.

Genetic risk score may help identify Type 2 diabetes patients with a higher risk for cardiovascular events

A risk score based on a gene map predicted the likelihood of high blood pressure leading to heart problems or stroke in people with Type 2 diabetes, according to a study published today in the American Heart Association's peer-reviewed journal Hypertension.
