This guide explains the mechanisms behind Parkinson's and provides detailed information about common - and lesser-known - symptoms. It summarizes the primary means of diagnosis and covers all the conventional treatments along with their pros and cons. However, a large part of the book is devoted to alternative treatments for Parkinson's, including Dr Perlmutter's glutathione therapy - a programme designed around an over-the-counter natural supplement. Other alternative therapies are also covered. A special section of the book focuses on ways that patients can deal with symptoms such as sleep problems, freeze attacks, anxiety, depression and muscle spasms, and attention is also given to carers, friends and families of sufferers.
