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.

Research reveals sex differences in microglia response to injury

A collision happens. Someone is hurt, a head injury, a concussion. Just as the first responders arrive to help the person, inside the brain, another "crew" of responders is busy clearing debris and repairing injured tissue.

Exploring the use of genomic classifier tests in prostate cancer risk stratification

A systematic review found that while genomic classifier (GC) tests may influence risk classifications or treatment decisions for patients with localized prostate cancer (PCa), there is a need for better data on their cost-effectiveness, clinical utility, and their impact on racial and ethnic groups, particularly Black men.

Stem cell therapy shows promise in restoring brain activity after stroke

Every 40 seconds, someone in the United States has a stroke. For survivors of the most common type of stroke, called an ischemic stroke, only about 5 percent fully recover.

Study reveals brain aging in sickle cell patients

Individuals with sickle cell disease – a chronic illness where misshapen, sticky blood cells clump together, reducing oxygen delivery to organs – are at a higher risk for stroke and resulting cognitive disability.

U.S. launches national plan to tackle Parkinson's disease and related disorders

With support from the U.S. Department of Health and Human Services (HHS) Office of the Assistant Secretary for Health (OASH), the National Institutes of Health (NIH) is leading the implementation of the Dr. Emmanuel Bilirakis and Honorable Jennifer Wexton National Plan to End Parkinson's Act (P.L. 118-66), which was signed into law on July 2, 2024.

Protein CD74 could predict immunotherapy response in bowel cancer

Researchers at the Francis Crick Institute and Barts Cancer Institute, Queen Mary University of London, have shown that the amount of a protein called CD74 can indicate which people with bowel cancer may respond best to immunotherapy.

Unmasking the gender bias in Tourette syndrome diagnosis

Tourette syndrome is currently diagnosed about three times more frequently in males than in females. A new study finds that female individuals are less likely to be diagnosed with the syndrome, take longer to receive a diagnosis and are older when they are diagnosed than male individuals. The study is published in the January 15, 2025, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Overcoming limitations of traditional CVD drugs

Announcing a new publication for Acta Materia Medica journal. Cardiovascular diseases (CVDs) pose a significant threat to human health due to the high mortality and morbidity rates. Traditional drugs often have limited efficacy due to inherent constraints, such as low bioavailability and notable side effects.

Retina vascular fingerprint offers non-invasive way to predict stroke risk

A vascular 'fingerprint' on the light sensitive tissue layer at the back of the eye-the retina-can predict a person's risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.

COVID-19 infection linked to increased cases of ME/CFS

New findings from the National Institutes of Health's (NIH) Researching COVID to Enhance Recovery (RECOVER) Initiative suggest that infection with SARS-CoV-2, the virus that causes COVID-19, may be associated with an increase in the number of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) cases.

U.S. dementia cases expected to surge with aging population

A new study shows that the risk of developing dementia anytime after age 55 among Americans is 42%, more than double the risk reported by older studies.

CeVD-related brain network phenotype can provide insights into cognitive decline trajectory

Researchers have uncovered novel insights into how brain function disruptions related to cerebrovascular disease (CeVD) interact with Alzheimer's disease (AD) pathology to impact neurodegeneration and cognition in older adults.
