Parkinson's is a neurodegenerative disorder that causes the loss of movement in people. The dopamine circuits that span the brain begins to deteriorate and a person will become more rigid, lose fine motor control and eventually even aspects of cognitive and emotional processing. Much is being done to treat Parkinson's around the world but today we are studying how to better understand the beginning of the disease. Prof. Borghammer has the amazing title of being a Nuclear Medic and uses radioactive isotopes to measure the metabolism of dopamine not just across the brain but also in our intestines. The intestines have a complex neural structure of their own and research spanning decades is now showing that dopamine degeneration may begin outside of the brain.
