Common stomach bacterium linked to Alzheimer's through newly identified pathway

Researchers have identified a mechanism by which Helicobacter pylori—a bacterium infecting roughly half the global population—may trigger Alzheimer's disease through immune signaling in the brain. The finding could reshape screening and treatment strategies for a bacterium typically considered a gastrointestinal concern, and may open new diagnostic or therapeutic avenues for neurodegenerative disease prevention.
