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.

UT Southwestern researchers discover protein that leads to brain cell death during stroke

One particular protein is the final executioner of events that result in the death of brain cells during stroke, researchers from UT Southwestern Medical Center and their collaborators report. This finding could ultimately lead to new ways to protect against brain damage.

Researchers develop new 4D flow imaging technique that helps predict stroke risk

Affecting 33.5 million patients worldwide, atrial fibrillation is the most common form of cardiac arrhythmia. As if having an irregular heart beat wasn't troubling enough, patients with atrial fibrillation are also much more likely to have a stroke.

Adapta Medical receives FDA market clearance for touchless urinary catheter

Adapta Medical, Inc. has received FDA market release for the PerfIC Cath intermittent touchless urinary catheter. The sterile catheter system was designed by J. Glen House, MD, a C7 quadriplegic with limited finger dexterity.

Johns Hopkins researchers identify protein that triggers brain cell death from strokes and injuries

Despite their different triggers, the same molecular chain of events appears to be responsible for brain cell death from strokes, injuries and even such neurodegenerative diseases as Alzheimer's.

New awards to explore role of glymphatic system in small vessel disease and trauma

More than $4.5 million in new grants to the lab of University of Rochester Medical Center scientist Maiken Nedergaard, M.D., D.M.Sc., underscore the important role the brain's waste disposal system may play in a range of neurological disorders.

Women may have better verbal memory skills than men during early stages of Alzheimer's disease

Women may have better verbal memory skills than men even when their brains show the same level of problems metabolizing glucose, which occurs in people with Alzheimer's disease, according to research published in the October 5, 2016, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Brain rehabilitation via a mobile app? An interview with Keith Cooper

When a person has a brain injury due to a stroke or a trauma, they typically start in a hospital emergency room to treat any life threatening injuries. They are then often transferred to an inpatient rehabilitation program at the hospital where they receive intensive physical and cognitive therapy until they are well enough to transition home.

Scientists identify new pathway in the brain that can be targeted to alleviate depression

Northwestern Medicine scientists have discovered a new pathway in the brain that can be manipulated to alleviate depression. The pathway offers a promising new target for developing a drug that could be effective in individuals for whom other antidepressants have failed.

BUSM scientists map active human apoptosome to provide better understanding of cell death

Programmed cell death, or apoptosis, plays a central role in the maintenance of human health by providing a line of defense against unrestricted cell growth that occurs in many cancers and AIDS as well as in neurodegenerative diseases and stroke.

NCDR provides data to study appropriate use of oral anticoagulant therapy

The American College of Cardiology's National Cardiovascular Data Registry was the source of data for research published throughout 2016, including a study examining if atrial fibrillation patients are being prescribed oral anticoagulants, how appropriate use criteria correlates to angioplasty rates and the variation among racial groups for revascularization procedures.

New WHO model provides detailed air pollution-related health data

A new World Health Organization air quality model confirms that 92% of the world’s population lives in places where air quality levels exceed WHO limits. Information is presented via interactive maps, highlighting areas within countries that exceed WHO limits.

Non-contrast MRA can be viable diagnostic alternative for patients with chronic kidney disease

Patients with diabetes or renal failure are at high risk for deadly and debilitating vascular diseases, however, the most common imaging tool to evaluate the blood vessels uses a contrast agent that can further damage the kidneys.

Study underscores importance of preventing risk factors across entire lifespan

Prevention of cardiovascular disease in mid- to later life in black and white Americans is an increasingly important health concern, according to a study from the Reasons for Geographic and Racial Differences in Stroke project recently published in the Journal of the American Geriatrics Society.

Immunotherapy already in clinical trials for cancer could slow progression of Parkinson's disease

Researchers at Johns Hopkins report they have identified a protein that enables a toxic natural aggregate to spread from cell to cell in a mammal's brain — and a way to block that protein's action.

Does exercise eliminate the ill effects of sitting? An interview with Prof. Ulf Ekelund

In short, the detrimental effects of sitting for prolonged hours can be divided into acute, or short-term, and long-term effects.

Study finds no evidence that exercise may lower woman’s risk of developing MS

A large, new study shows no evidence that exercise may reduce a woman's risk of developing multiple sclerosis (MS).

Penn researchers search twitter for tweets about cardiovascular disease

For years, marketers and other commercial data-miners have been using Twitter's vast database of "tweets" to gauge consumer attitudes and track events. Now medical researchers are getting in on the trend.

Researchers find common brain abnormalities shared across multiple emotional disorders

Researchers have long known that emotional disorders have a lot in common. Many often occur together, like depression and social anxiety disorder. Treatments also tend to work across multiple disorders, suggesting shared underlying elements.

Study shows ancient grain varieties may help reduce risk factors for CVD

Eating bread made with ancient grains as part of a healthy diet could help lower cholesterol and blood glucose levels—leading risk factors for heart attack and stroke—according to new research published in the International Journal of Food Sciences and Nutrition.

UCLA-led study shows treatment can provide benefits up to 7.3 hours after onset of stroke

Time is of the essence when getting people stricken with acute ischemic strokes to treatment. And the use of stent retrievers — devices that remove the blood clot like pulling a cork out of a wine bottle — has proven to be a breakthrough for removing the life-threatening blockage of blood flow to the brain.
