Scientists have identified a protective brain pathway that may help slow the progression of Parkinson's disease by strengthening the brain's own dopamine-producing neurons, but the positive effect was ...

Scientists have known for some time that Alzheimer’s disease affects brain regions differently. And they have a detailed understanding of how misfolded tau forms toxic tangles in the brain, impairing ...

Between the ages of three and four, children undergo a major leap in their ability to use grammar, and recent research provides evidence that this behavioral milestone corresponds to the maturation of ...

For over 60 years, metformin has been a first-line treatment for type 2 diabetes, yet scientists have not fully understood how it works. Researchers at Baylor College of Medicine, along with ...

Cerebral small vessel disease (cSVD) encompasses a range of pathological processes that damage arterioles, capillaries, or venules supplying brain tissue. It is a leading cause of stroke (both ...

Microplastics could be fueling neurodegenerative diseases like Alzheimer's and Parkinson's, with a new study highlighting five ways microplastics can trigger inflammation and damage in the brain. More ...

Scientists have long known that stress and addiction travel together, but the biological connection between a hard day and a hard-to-break habit has been far less clear. New research now identifies a ...

New peer-reviewed research from University College Cork traces how voluntary exercise reshapes tryptophan metabolism through the gut microbiota, lowering a key receptor in the memory center of the ...

In this figure, an intestinal immune cell detects medium-chain fatty acids produced by aging gut bacteria through the GPR84 receptor, releasing inflammatory molecules that block signaling along the ...

Racemic ketamine has long been used for anesthesia, analgesia, and sedation [1], and clinical trials have established its rapid antidepressant effects in treatment-resistant patients with major ...
