Study examines biomarkers, economic factors that may increase risk for cognitive decline

By Angie Hunt, Iowa State University News Service

An image of your retina may help Iowa State University researchers determine your risk for Alzheimer’s disease even before other symptoms are detectable. Numerous studies have shown the inner layer of the retina is thinner in people with Alzheimer’s disease. But what if a noninvasive scan could spot changes to the retina before diagnosis and…

Antioxidant puts up fight, but loses battle against toxic protein linked to Alzheimer’s disease

By Angie Hunt, Iowa State University News Service

New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer’s disease.
