Scientists reverse Alzheimer's memory loss in mice by using NAD+ to restore brain energy, defying decades of research.

Stanford Medicine researchers have identified a specific gut bacterium that accelerates memory loss in aging mice, and they ...

Memory loss is often viewed as a brain problem, but the digestive system plays a major role. Research published in Nature shows that age-related bacterial changes disrupt nerve communication, and ...

A study in mice concluded that memory problems associated with age may be driven by our gut microbiome and that the vagus ...

We become forgetful as we age. This is often seen as a universal truth, but in fact it is far from universal: some people remain incredibly sharp at 100 years old, while others experience memory loss ...

A study published in Nature on August 6, 2025, found that lithium is the only metal significantly depleted in the prefrontal cortex of people with mild cognitive impairment and Alzheimer’s disease, ...

Virginia Tech researchers have shown that memory loss in aging may be reversible. Using CRISPR tools, they corrected molecular disruptions in the hippocampus and amygdala, restoring memory in older ...

Researchers found that gut microbes may contribute to memory loss by disrupting signals between the intestine and the brain.

The new study asks whether part of the answer lies outside the brain entirely, in microbes all the way down in the gut ...

Stress is the brain’s natural response to fear, but it often disrupts memory in the process, potentially impacting the possibility of memory loss. When preparing for a big presentation or taking a ...
