Increased level of magnetic iron oxides found in Alzheimer's disease

...the chemical form of iron associated with these diseases, its role in neurodegeneration (if any) and its origin. Investigations of brain iron based on histochemical staining techniques have generally ignored its chemical state. This study shows a clear correlation in the concentration and the size of the bioge...
