Excess Iron May Cause Alzheimer’s Disease
High iron levels in your blood can lead to the production of free radicals that can damage neurons in your brain. It’s also believed that iron accumulates at high levels, and is extremely reactive in the beta-amyloid plaques found in the brains of Alzheimer’s patients.
A new animal study revealed that reducing iron levels in the blood triggered levels of beta-amyloid and phosphorylated tau protein, which disrupts the ability of neurons to conduct electrical signals, to return to normal.
Experts on metal metabolism in the body said the research highlights the role of metal ions in the development of Alzheimer’s, as excess iron accumulation in the brain is a consistent observation in Alzheimer’s disease.
