Increased iron and oxidative stress are separately related to cognitive decline in elderly

Abstract

Our study provides evidence of increased markers of iron deposition and oxidative stress in patients with cognitive dysfunction. It seems likely that these markers negatively affect the MMSE score. Interestingly, we did not find any correlation between the markers of iron deposition and oxidative stress. Future studies will be required to demonstrate whether diminishing iron and oxidative stress will enhance MMSE score and thereby ameliorate cognitive impairment.
