Is there such a thing as too much iron?

Dr Dominic Hare wants to know whether having too much iron in your brain might actually be a bad thing. The brain is not very good at shedding itself of excess iron, and Dominic has shown that, in mice, iron kills dopamine producing cells - giving them Parkinson's disease. By examining teeth, which contain a record of all the iron you were ever exposed to, and advanced brain images that give us a snapshot of current iron levels, Dominic will be able to see if excess iron is bad for the human brain.
