A landmark study published in Nature by Stanford Medicine and Arc Institute researchers has identified how the gut bacterium Parabacteroides goldsteinii drives age-related memory loss in mice by triggering inflammation that disrupts vagus nerve signaling to the brain's hippocampus. The research demonstrated that cognitive decline could be fully reversed through vagus nerve stimulation, GLP-1 receptor agonists (drugs in the same class as Ozempic), and targeted bacteriophage therapy — opening a potentially transformative new front in the fight against dementia, which affects over 55 million people worldwide.
