Beta-amyloid

Beta-amyloid is a protein fragment that naturally forms in the brain. Normally, it is broken down and cleared away, but in Alzheimer's disease, these fragments accumulate and form sticky clumps called plaques. These plaques can interfere with communication between brain cells and trigger inflammation and cell damage. The buildup of beta-amyloid is considered a key marker and contributing factor in the development of Alzheimer's, affecting memory, thinking, and other cognitive functions. Researchers study beta-amyloid to better understand the disease and develop potential treatments aimed at reducing its accumulation.
