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.

Obicetrapib slashes LDL cholesterol by over 30% in high-risk heart patients

A large multinational trial published in the New England Journal of Medicine shows that obicetrapib significantly lowers LDL cholesterol in high-risk cardiovascular patients. The CETP inhibitor also improved key lipid parameters with no major safety concerns, supporting its role in future combination therapies.

Ovary and fallopian tube removal linked to lower death risk in BRCA carriers with breast cancer

Women diagnosed with breast cancer who carry particular BRCA1 and BRCA2 genetic variants are offered surgery to remove the ovaries and fallopian tubes as this dramatically reduces their risk of ovarian cancer.

Study shows no connection between PM2.5 spikes and major cardiovascular events

A Danish cohort study investigated whether long-term exposure to repeated monthly peaks of fine particulate matter (PM2.5) raises the risk of major adverse cardiovascular events. Despite higher PM2.5 peak exposure among affected individuals, no significant association with cardiovascular risk was found.

High intake of ultra processed foods linked to early signs of Parkinson's

People who eat more ultra processed foods like cold breakfast cereal, cookies and hot dogs are more likely to have early signs of Parkinson's disease when compared to those who eat very few ultra processed foods, according to a study published in the May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Study links sleep apnea to damage in brain areas critical for memory

Obstructive sleep apnea, a condition that causes lower oxygen levels during sleep, is linked to degeneration of brain regions associated with memory through damage to the brain's small blood vessels, according to a study published May 7, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

HIV testing and outreach falter as Trump funding cuts sweep the South

Storm clouds hung low above a community center in Jackson, where pastor Andre Devine invited people inside for lunch. Hoagies with smoked turkey and ham drew the crowd, but several people lingered for free preventive health care: tests for HIV and other diseases, flu shots, and blood pressure and glucose monitoring.

Combining vagus nerve stimulation with therapy provides lasting PTSD relief

In a first-of-its-kind clinical study, scientists at The University of Texas at Dallas and Baylor University Medical Center showed that patients with treatment-resistant PTSD were symptom-free up to six months after completing traditional therapy paired with vagus nerve stimulation (VNS).

Phthalates in plastics linked to over 350,000 heart deaths worldwide

A global modeling study in eBioMedicine links phthalate exposure from plastics, especially DEHP metabolites, to over 356,000 cardiovascular deaths in 2018. Exposure was highest in Asia, the Middle East, and Africa, disproportionately affecting lower-income countries.
