Alzheimer's can be spotted before plaques develop

The early stages of Alzheimer's disease could be detected before plaques develop, a new study found. A peptide spots a protein made when the brain get inflamed or damaged and increases before the amyloid plaques develop - the first sign the disease is taking hold. The findings could be used to diagnose those patients at high risk of the disease and used to deliver drugs to areas of the brain getting infected.
