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.

UA scientist receives grant to study how traumatic brain injury changes brain communication

A scientist at the University of Arizona College of Medicine - Phoenix has received a $1.65 million grant to find out how a traumatic brain injury changes communication in the brain.

Study uncovers genetic trigger that may help the brain to recover from stroke, other injuries

Scientists have found a genetic trigger that may improve the brain's ability to heal from a range of debilitating conditions, from strokes to concussions and spinal cord injuries.

Researchers measure whether transcranial direct current stimulation generates EFs in deep brain areas

A defining characteristic of stroke is the loss of motor control due to structural damage in specific brain areas. In fact, motor impairments (or deficits) are the number one complication after stroke.

New device achieves 92% accuracy in detecting patients with severe stroke

A new device worn like a visor can detect emergent large-vessel occlusion in patients with suspected stroke with 92 percent accuracy, report clinical investigators at the Medical University of South Carolina, Mount Sinai, the University of Tennessee Health Sciences Center and elsewhere in an article published online on March 6, 2018, in the Journal of Neurointerventional Surgery.

Study finds low treatment rates for people with elevated cholesterol levels

Less than 40 percent of people with severe elevations in cholesterol are being prescribed appropriate drug treatment, according to a nationally representative study reported in the American Heart Association's journal Circulation.

Researchers develop comprehensive map of genetic risk factors for stroke

Stroke is a serious disease affecting blood flow to and from the brain, and is the second leading cause of death worldwide. Stroke is characterized by a sudden onset of neurological dysfunction, caused by a blood clot or hemorrhage in a cerebral artery. While many genetic variants and lifestyle behaviors have been identified as risk factors for stroke, the genetic basis for the disease is unknown.

Depression may be linked to increased risk of atrial fibrillation

A study has shown that depression may be a risk factor for atrial fibrillation, a common heart rhythm disorder that can cause clot formation and stroke.

New findings could have revolutionary impact on quality of life of older people

Researchers from UNSW and Harvard Medical School have discovered that replacing two naturally occurring molecules in the body could reverse symptoms of aging, potentially influencing how the body responds to and performs exercise.

Study suggests detailed neuropsychological assessment for brief cardiac arrest survivors

Patients who survive a brief cardiac arrest and who appear neurologically intact should nonetheless receive a detailed neuropsychological assessment before being discharged, suggests a joint study by researchers at Baycrest's Rotman Research Institute and Israel's Rambam Medical Center.

Menopausal hormone therapy taken soon after menopause may benefit the brain

Taking menopausal hormone therapy soon after menopause to relieve symptoms may also benefit the brain, according to a study published in the March 21, 2018, online issue of Neurology, the medical journal of the American Academy of Neurology.

UCLA-led study suggests unexpected reason for reduction in cardiovascular health disparities

The nation's overall cardiovascular health worsened from 1988 to 2014, with disparities among racial and ethnic groups dropping slightly. But the reduction in disparities was due to worsening health among whites -- not improvements among African-Americans and Mexican-Americans, a new UCLA-led study suggests.

Study explores use of smartwatch to detect atrial fibrillation

A smartwatch coupled with a machine learning algorithm was able to detect irregular heartbeat, or atrial fibrillation, with high accuracy in a small group of patients undergoing treatment to restore normal heart rhythm but with lower accuracy in a larger group of people with a self-reported history of AF.

Vitamin D deficiency linked to metabolic syndrome in postmenopausal women

Results of a study carried out in Brazil showed a strong association between vitamin D deficiency and metabolic syndrome in postmenopausal women.

High-fat, high-cholesterol diet depletes ranks of artery-protecting immune cells

New research from scientists at the La Jolla Institute for Allergy and Immunology shows how a diet high in fat and cholesterol depletes the ranks of artery-protecting immune cells, turning them into promoters of inflammation, which exacerbate atherosclerotic plaque buildup that occurs in cardiovascular disease.

Increase in coffee consumption may help battle against colon cancer

A report that Americans are drinking a lot of coffee might be good news in the battle against colon cancer, scientists with the Simmons Cancer Center at UT Southwestern Medical Center say.

Are there risks from secondhand marijuana smoke? Early science says yes.

The inspiration arrived in a haze at a Paul McCartney concert a few years ago in San Francisco. “People in front of me started lighting up and then other people started lighting up,” said Matthew Springer, a biologist and professor in the division of cardiology at the University of California-San Francisco. “And for a few naive split seconds I was thinking to myself, ‘Hey, they can’t smoke in AT&T Park! I’m sure that’s not allowed.’ And then I realized that it was all marijuana.”
