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

(Iowa State University) New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer's disease. The antioxidant, superoxide dismutase or SOD1, improves cognition, but an Iowa State University research team found SOD1's protective benefits dramatically weaken when levels of tau proteins -- a hallmark of Alzheimer's disease -- increase.
