Could Alzheimer’s Spread Like Infection Throughout the Brain?
U.S. News & World Report

With findings that might alter the path of Alzheimer’s research, scientists say misfolded forms of two proteins appear to spread through patients’ brains similar to an infection.

The findings suggest that Alzheimer’s is a “double-prion” disorder. This discovery could help lead to new treatments that focus directly on prions, according to researchers from the University of California, San Francisco.

A prion is a misshapen protein that can force other copies of that protein into the same misfolded shape and spread in the brain. It’s best known for its role in bovine spongiform encephalopathy — “mad cow” disease — and Creutzfeldt-Jakob disease (CJD), a degenerative brain disorder.
