Amyloid theory

The Amyloid theory suggests that Alzheimer's disease is primarily caused by the buildup of amyloid-beta proteins in the brain. These proteins can clump together to form sticky plaques, which disrupt normal brain cell function and communication. Over time, this leads to the loss of neurons and cognitive decline. The theory has guided much research into understanding and treating Alzheimer's, though it is one of several hypotheses about the disease's underlying causes. It's a focus because clearing or preventing amyloid buildup might help slow or prevent disease progression.
