Question: What is the link between the amount of iron in the brain and Alzheimer's?

Mobeen Ali answered on 9 Mar 2016:

As we get older, the amount of iron in our brains increases and is linked to a higher risk of developing Alzheimer’s disease. The neurons in the brain require a small amount of iron to function properly. Too much iron can damage the neurons which negatively affects the brains ability to process information and store memories.
