Mismanaged iron in the brain is seen in those patients with neurodegenerative diseases: Alzheimer's, early onset Parkinson's, epilepsy, multiple sclerosis, and Huntington's disease.
Hmmm.... makes you wonder. In the last 4 years, I've had 2 spikes in blood iron. I compared the testing dates with my blood donor history and found that in both cases, there had been a "gap" in my regular blood donations for one reason or another. The worst one happened after I hadn't given blood for over a year.
I think I need to talk to my doctor about this, especially since I'm no longer menstruating, so I'm at higher risk for extra iron building up in my body. I also need to do some more research.
