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 finds a steady rise in cardiovascular-related complications during pregnancy

Cardiovascular-related health problems may occur in as many as 1 out of every 7 pregnancies, even among people who don't already have heart disease, according to new research published today in the American Heart Association's flagship journal Circulation.

Long-term exposure to industrial solvent associated with elevated Parkinson's disease risk

Long-term exposure to the industrial solvent trichloroethylene (TCE) outdoors may be linked to an increased risk of Parkinson's disease, according to a large nationwide study published in the October 1, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Genetic risk scores fail to predict survival after diagnosis

Research indicates that disease susceptibility genetics poorly predict survival, while longevity PGSs offer stronger associations with post-diagnosis mortality.

Inflammation at the heart’s core: What clinicians and families can do now

Chronic low-grade inflammation is a key driver of cardiovascular disease, even when cholesterol is controlled. The ACC’s 2025 Scientific Statement highlights hsCRP as a routine risk marker and outlines lifestyle and pharmacologic anti-inflammatory strategies for prevention and treatment.

Most people who experience heart attack, stroke or heart failure have prior risk factors

More than 99% of people who went on to suffer a heart attack, stroke or heart failure already had at least one risk factor above optimal level beforehand, reports a large-scale study led by Northwestern Medicine and Yonsei University in South Korea.

Sleep apnea patients in high-pollution areas suffer higher disease severity, study shows

People who have obstructive sleep apnea (OSA) may suffer worse symptoms if they live in areas with higher levels of air pollution, according to a multi-national study presented at the European Respiratory Society (ERS) Congress in Amsterdam, the Netherlands.

Telestroke expands care access but prolongs critical treatment time

Stroke patients evaluated using telemedicine (telestroke) have higher odds of receiving essential treatment, yet it takes them significantly longer to be treated - potentially limiting the benefits, a Michigan Medicine-led study finds.

Natural psychoactive molecule DMT reduces harmful effects of stroke in animal models

DMT, or dimethyltryptamine is a natural psychoactive molecule found in many plants and mammals. According to an article published in Science Advances, researchers from the HUN-REN BRC Institute of Biophysics and Semmelweis University Heart and Vascular Centre found that DMT reduces the harmful effects of stroke in animal models and cell culture experiments.

Calcium-induced release identified as key driver of dangerous muscle disorders

Researchers engineered mice with a mutation (E3896A) in the RyR1 calcium-binding site, eliminating calcium-induced calcium release (CICR) without affecting depolarization-induced calcium release.

Groundbreaking MRI technique reveals microvascular pulsations in the aging brain

Researchers at the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed a groundbreaking brain imaging technique that reveals how tiny blood vessels in the brain pulse with each heartbeat-changes that may hold clues to aging and diseases such as Alzheimer's.

Colorectal cancer first presents with unexplained strokes and blood clots

A new case report was published in Volume 12 of Oncoscience on September 15, 2025, titled "When strokes reveal a hidden malignancy: An atypical case of metastatic colorectal cancer with extensive thromboembolism."

Scientists map step-by-step activation of brain receptors

When it comes to brain proteins, small changes can make a dramatic difference. Researchers studying NMDA (N-methyl-D-aspartate) receptors, which are essential for learning, memory and moment-by-moment consciousness, know that even slight changes in their activity level can mean the difference between normal function and serious neurological disorders.

Skin-to-skin care linked to stronger brain development in preterm infants

Preterm infants born before 32 weeks who received more skin-to-skin contact while in the hospital showed stronger brain development in areas tied to emotion and stress regulation than babies who received less skin-to-skin care, according to a study published in the September 24, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Cognitive challenges rise sharply among younger adults in the U.S.

A growing number of U.S. adults-particularly those under 40-are reporting serious challenges with memory, concentration and decision-making, according to a new study published in the September 24, 2025, online issue of Neurology, the medical journal of the American Academy of Neurology.

Global cancer cases and deaths expected to soar by 2050 despite advances in treatment

There has been a rapid increase in the global number of cancer cases and deaths between 1990 and 2023, despite advances in cancer treatment and efforts to tackle cancer risk factors over that same time period.

Lipoprotein(a) testing remains uncommon in the United States

Researchers from University of California San Diego School of Medicine have found that testing for lipoprotein(a) - a genetic risk factor for heart disease - remains uncommon in the United States, despite modest increases over the past decade.

High levels of albumin in the urine linked to increased risk of dementia

A study shows that people with higher levels of the protein albumin in their urine are at increased risk of developing dementia. The study, led by researchers at Karolinska Institutet, is published in the scientific journal Journal of Internal Medicine.
