A new target in the gut for reducing Alzheimer's risk

A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could ...

Electric fields offer new hope against aggressive brain cancer

More than a decade ago, Dr. Matthew Hebb was treating patients with Parkinson's disease using deep brain stimulation by implanting tiny electrodes into the brain and delivering electrical signals to control tremors. He wondered ...

Got ice‑cream brain freeze? Here's what is happening

With temperatures forecast to reach around 37°C (99°F) in places, reaching for an ice cream or an icy drink might seem like an excellent idea. There is, however, one small hazard to eating your frozen treat with too much ...

Potential language-specific brain network identified

The language network in your brain can be seen, even if you aren't saying a word. For a study published in Nature Communications, researchers used data from more than 1,900 functional magnetic resonance imaging (fMRI) scans ...

Sensory overload in kids has distinct neurobiological roots

Overreactions to ordinary sensory stimuli—a scratchy shirt tag, a roaring vacuum cleaner, an unfamiliar smell—are commonly associated with autism. But in fact, an estimated 15% to 20% of children experience such reactions, ...

How brain ripples help support working memory

Research from scientists at the University of California San Diego School of Medicine and collaborators has shed new light on how the human brain coordinates working memory, the process in which the brain encodes information ...

Blood-thinning medication linked to slower cognitive decline

People with both atrial fibrillation and Alzheimer's disease who are treated with modern NOAC blood-thinning medicines may experience a slower rate of cognitive decline. This is shown by a study from Karolinska Institutet ...

Protein secreted by immune cells may help drive brain aging

Brain-resident immune cells that have reached an old-age state called "senescence" secrete a protein that causes dysfunction in other brain cells, according to a study led by investigators at Weill Cornell Medicine. The discovery ...

Improving stroke care and innovation

Every 40 seconds, someone in the U.S. has a stroke, according to the Centers for Disease Control and Prevention. Because stroke is a leading cause of long-term disability and death, there is a growing need to develop innovative ...

Unexpected brain mechanism challenges assumptions about GLP-1s

For decades, obesity medications produced only modest weight loss. But in recent years, Ozempic and related GLP-1 therapies have transformed the field, enabling sustained weight loss of 10% to 15% or more. Despite their success, ...

AI framework decodes how brain regions talk to one another

For decades, neuroscientists have been able to record which parts of the brain show increased electrical activity during a behavior, such as when we form a memory or make a decision. But scientists haven't been able to determine ...
