This book looks interesting, too:

Making the Connection Between Brain and Behavior: Coping with Parkinson's Disease

By Joseph H. Friedman

"While patients and families are aware of the physical challenges that accompany Parkinson’s disease, few are prepared for the common behavioral issues that impact their quality of life, including depression, anxiety, dementia, paranoid delusions, and sleep disorders. This book, the only one of its kind, focuses entirely on an area that most doctors overlook. Written in layman’s terms, it helps readers understand and cope with a wide variety of Parkinson’s-related behavioral issues and offers guidance on communicating with the healthcare team."

From a review:

"As a neurologist who developed Parkinsonism myself I have in vain been searching for a comprehensive review of these problems, and now I have found it in Dr. Joseph Friedman's Making the Connection Between Brain and Behavior--Coping with Parkinson's Disease."
