99 Faces of Parkinson's disease is a comprehensive review of muscular, sensory, mental and a variety of other types of symptoms which Parkinson's patients experience. It is a great handbook for patients suffering with Parkinson's disease, as well as their friends, families and caregivers. In the past, its first edition was found very helpful for medical students, residents, nurses and physician assistants. The detailed description of all the possible symptoms and the brief discussion about treatments is mainly to open the doors for further discussions about these symptoms between patients and their caregivers. The book has been divided into easy subsections and chapters and there is a use of pictures and tables for easy understanding and emphasis of the important points. Several true patient stories have been included for better understanding of the disease. An attempt was made to cover each and every symptom of Parkinson's disease in this book because of the authors' belief that "an informed patient is a stronger patient", and "a patient armed with knowledge about the disease is ready to fight with the disease".
