I ordered 10 copies of this book for our Parkinson's Support Group because we get new members every month and their anxiety level is palpable. This book will help answer their questions and help them feel that all is not lost. I love Dr. Okun's book because it is full of hope and respect for all Parkinson's patients. I am rereading the chapter on DBS because I think that's where we are with my husband. This book helps me understand and gives context to the research summaries that I am reading but don't really understand. I hope the next edition enlarges the print-it's kind of small. Thanks Dr. Okun for this very special book!
