Stanford Study: Restoring Gut-Brain Communication Reverses Cognitive Decline in Aging Mice

The bagel they save for the regulars. Don't skim, savour.
Summary
Stanford Medicine researchers discovered that aging-related changes in gut bacteria composition trigger an inflammatory response that impairs communication between the gut and brain, leading to cognitive decline in mice. The study found that restoring this gut-brain communication pathway reversed cognitive decline and improved memory formation in aging mice to levels comparable to young animals.
Key quotes
· 4 pulledStanford Medicine researchers have found a critical link between bacteria living in the gut and aging-related cognitive decline.
The mouse study showed that the composition of the naturally occurring bacterial population that lives in the gut, known as the gut microbiome, changes with age — favoring some species of bacteria over others.
These changes are registered by immune cells in the gastrointestinal tract, which spark an inflammatory response that hampers the ability...
Restoring this connection helped old mice form memories as well as young animals.
