Never in history has there been greater hope that novel experimental therapies can support significant restoration of brain function. The field of restorative therapies in Parkinson's disease has passed the initial phase of pioneering experimental and clinical trials. There still does not exist restorative therapy that can be applied in large numbers of patients, but the initial trials have provided us with fundamental insight into the potential for plasticity in the diseased brain. This book gives an overview of the current state-of-the-art research for brain repair, what the challenges are and an indication of what research can provide for the next generation of people with Parkinson's disease.
