Gut Bacterium Linked to Age-Related Memory Decline in Mice: A new Nature study identifies a gut bacterium, Parabacteroides goldsteinii, as a potential driver of cognitive decline in aging mice. Researchers found that the microbe proliferates in older animals and disrupts signalling along the vagus nerve, a key communication pathway between the gut and brain. In experiments, young mice exposed to the microbiomes of older mice developed memory pro…
A study published on March 11, 2026 in the scientific journal Nature revealed that certain intestinal microbes can favor memory loss in aging mice. Researchers observed that some bacteria in the intestine interfere with communication between the digestive system and the brain, which ends up affecting the ability to learn and remember.
