These amyloid plaques then destroy more and more myelin, which disrupts brain signaling and leads to cell death and classic clinical signs of Alzheimer's. Because myelin and the cells that produce it, called oligodendrocytes, have the highest levels of iron compared to any other cell in the brain, researchers believe that elevated tissue iron may trigger the tissue breakdown associated with Alzheimer's disease.
