Parkinson’s disease is a neurological condition that affects the brain and other parts of the nervous system. The gradual loss of nerve cells leads to a suite of characteristic motor and non-motor symptoms. What causes these cells to die and how the pathology develops in the nervous system are not yet clear but multiple lines of investigation are being pursued to answer these questions. In this animation, we explore some of the latest in Parkinson’s disease research. This Nature Video is editorially independent. It is produced with third party financial support.
