Parkinson's disease is a common and devastating progressive disorder that primarily affects motor function. In this exciting and timely book, novel approaches to repairing the parkinsonian brain are described by some of the world's leading scientists and clinicians in the field. Dealing with cutting-edge research, it covers several important topics including medical ethics, clinical trial design, stem cell biology, intracerebral transplantation, brain imaging, neurotrophic factors and neural regeneration. The comprehensive chapters are geared to an audience of neuroscientists, neurologists, neurosurgeons and anyone interested in how findings in the research laboratory can effectively be transferred to the clinic. Restorative therapies in Parkinson's disease have pioneered translational research in the area of brain repair for close to three decades. This book clearly shows that research in Parkinson's disease continues to play a leading role and can provide a model for how functional restoration might be achieved in several brain disorders in the future.
