Gasdermin D found to play a crucial role in heart arrhythmias

Atrial fibrillation (AF) is a common form of heart arrhythmia, a serious condition in which the heart beats so fast that its upper chambers, the atria, quiver. This irregular heartbeat can increase the risk of severe conditions, including heart failure, dementia and stroke.

Simultaneous screening for hypertension and arrhythmia could prevent strokes

A group of 29 international experts says that simultaneous screening for hypertension and heart arrhythmia could prevent thousands of strokes.

Unveiling leptin signaling in the DMH for metabolic effects

Scientists at Pennington Biomedical Research Center have gained greater clarity in the brain regions and neurons that control metabolism, body temperature and energy use.

Study finds association between heart dysfunction and smaller brain volumes

People who have early signs of heart problems may also have changes in brain health that can be early signs of dementia, such as loss of brain volume, according to a meta-analysis published on March 26, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Neighborhood disadvantage linked to higher dementia risk

People living in more disadvantaged neighborhoods may be more likely to develop dementia than people living in neighborhoods with fewer disadvantages, according to a study published on March 26, 2025, online in Neurology, the medical journal of the American Academy of Neurology.

Higher education linked to faster cognitive decline after stroke

When someone has a stroke, it can accelerate the loss of cognitive ability over the coming years.

‘I am going through hell’: Job loss, mental health, and the fate of federal workers

The National Institutes of Health employee said she knew things would be difficult for federal workers after Donald Trump was elected. But she never imagined it would be like this.

New open-source tool identifies aging cells to help fight chronic diseases

For human health, prematurely aging cells are a big problem. When a cell ages and stops growing, its function changes, which can cause or worsen cardiovascular disease, Alzheimer's disease and other chronic diseases.

New brain metabolism model reveals key targets for reversing aging

The most comprehensive model of the brain’s metabolism, incorporating more than 16,800 biochemical interactions, has identified key targets to reverse the age-related decline in brain function.

Blood test shows high accuracy in detecting Alzheimer's in Asian populations

A study in Alzheimer's & Dementia, a leading journal in dementia research, has demonstrated the high accuracy of plasma p-tau217 as a blood-based biomarker for detecting abnormal brain beta-amyloid (Aβ) pathology, a hallmark of Alzheimer's disease (AD).

ADHD may be linked to increased risk of developing dementia later in life

An adult brain affected by attention deficit disorder with or without hyperactivity (ADHD) presents modifications similar to those observed in individuals suffering from dementia.

Understanding the role of iron-dependent ferroptosis in immune suppression

Iron-dependent ferroptosis, a non-apoptotic cell death mechanism, is gaining attention for its role in immune suppression.

Study links type 2 diabetes to weakened reward signals in the brain

The high comorbidity of type 2 diabetes (T2D) with psychiatric or neurodegenerative disorders points to a need for understanding what links these diseases.

Smell-based test taken at home could predict cognitive impairment in older adults

When it comes to early detection of cognitive impairment, a new study suggests that the nose knows. Researchers from Mass General Brigham developed olfactory tests-in which participants sniff odor labels that have been placed on a card-to assess people's ability to discriminate, identify and remember odors.

What do Blue Zone diets have in common? Polyphenols that may slow aging

Scientists reviewed how polyphenol-rich diets in Blue Zones may help people live longer, healthier lives by targeting biological hallmarks of aging. They call for more research to measure polyphenol intake and test its effects on human longevity.

Skipping exercise? Just sitting less may still improve your metabolic health

Older adults who limit their sedentary time have lower metabolic syndrome risk, regardless of how active they are or how healthy they eat. Even light movement can support better metabolic health when replacing prolonged sitting.

Advanced imaging technique reveals how nuclear pores regulate molecular movement

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into and out of the nucleus.

Research reveals how dendrites connect memories in the brain

If you've ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather in their spiny extensions called dendrites.

Targeting brain’s waste removal system may help combat cognitive decline

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease, among others.
