You may be reading this book because you or someone in your life recently received a diagnosis of Parkinson's disease (PD). Perhaps it was not so recently, but you are now reflecting more on what the diagnosis means for you. Everyone's PD story is different. Many people with PD vividly remember the moment they were diagnosed and view it as the beginning of a journey; a new life path. Often, they think back a few years and recognize subtle symptoms they missed at the time.
