Reisa Sperling: How soon can we predict Alzheimer’s?

Can advances in brain scans and other testing techniques help us predict who will come down with Alzheimer’s — decades before symptoms show?  Reisa Sperling of Brigham and Women’s Hospital reports on the latest research in battling a disease whose symptoms show up far too late to cure.

Sperling’s work in the Dominantly Inherited Alzheimer’s Network (DIAN) study was published July 11th in the New England Journal of Medicine. In this work, a team of researchers offered a timeline of the disease progression, with biomarkers, including changes in brain size and spinal fluid, evident as early as 25 years before the onset of symptoms.
