New evidence indicates that Parkinson's disease is preceded by a period during which healthy regions of the brain take over the functions of damaged ones.

Neurologist Bart van Nuenen performed a unique study involving people who are clinically still healthy and free from disease manifestations, but who have an increased risk of developing Parkinson's disease later in life due to their genetic predisposition. Van Nuenen will defend his PhD thesis based on this study on 22 November.
