“With the help of advanced scanning techniques, we’ve shown that Parkinson’s disease can be divided into two variants, which start in different places in the body. For some patients, the disease starts in the intestines and spreads from there to the brain through neural connections. For others, the disease starts in the brain and spreads to the intestines and other organs such as the heart,” explains Per Borghammer.
