Swelling Along Brain’s Axons May Be True Culprit in Alzheimer’s Disease

The formation of plaques can cause the accumulation of spheroid-shaped swellings along axons near the amyloid plaque deposits. The swellings are caused by lysosomes, which digest cellular waste. As the swelling enlarges, it can block the transmission of signals from one area of the brain to another.
