How a chemical reaction triggers brain inflammation in Alzheimer's disease

Researchers have identified how chronic overactivation of the brain's immune cells triggers damaging inflammation in Alzheimer's disease. The brain possesses its own immune system designed to detect and respond to threats, but in Alzheimer's patients, these immune cells become persistently hyperactive, causing inflammation that damages critical connections between neurons. This discovery provides important insights into the underlying mechanisms of neurodegeneration and could lead to new therapeutic approaches targeting immune system dysfunction. Understanding this chemical reaction is crucial for developing treatments that may slow or prevent cognitive decline in Alzheimer's patients.
