Obsessive-Compulsive Disorder and Tourette’s Syndrome [PDF ebook] 
The Science of Mental Health

First published in 2002. Obsessive-compulsive disorder (OCD) and Tourette’s syndrome (TS) are treated together in this volume because symptoms of each often co-occur and because there are substantial overlaps in genetic risks and possibly in the neurobiology underlying these disorders.
