This book addresses all of the new and emerging Parkinson's disease therapies (stem cells, gene therapy, optogenetics, etc.). The most humbling experience of my life has been the time I have spent with families, and with patients suffering from Parkinson's and chronic neurological diseases. I use the word humbling, because time after time, in person, and also on the web forum, we have uncovered simple and addressable issues and secrets that have changed people's lives. For some sufferers it has meant walking again, for others it has restored their voices, and for many it has resulted in the lifting of a depression, anxiety and desperation cloud that has obscured their dreams, and robbed them of potential unrealized happiness. I never assume a sufferer or family member is aware of the "secrets" that may lead to hope and to a happier life. We must share these secrets, and this is the purpose of this book. Each chapter of this book reveals an important secret, and with each secret I will explain the insight, the rationale, the empiricism, and the science behind it. In each chapter I will also try to reveal a little more about myself, and a lot more about the patients and talented clinicians who gifted the Parkinson's secrets. These patients planted the seed of faith. They learned to grow hope, and they discovered the core values necessary to achieve happiness despite the chronic illness of Parkinson's disease. - Publisher.
