Tourette Syndrome and Human Behavior      by David E. Comings I highly recommend this book. Do not be afraid of the size of this book as 687 pages, not including the various tests which will assist you and the glossary and index.

This book leaves nothing out. It answers *every* question imaginable. Easy to read and understand and yet thorough in it's approach. If you want to fully understand tourette syndrome, it's diagnosis, treatment, the genetics, behavior, cause, and much more, this is the book for you.

Search for the Tourette Syndrome and Human Behavior Genes      by David E., MD Comings "Dr. Comings tells the story of his 18 years of involvement with Tourette syndrome, from both the level of treating thousands of patients with this common and complex disorder, to his clinical, genetic and molecular genetic research. He quickly realized this was more than just a tic disorder. His patients and their relatives had problems with a wide range of behaviors including attention deficit hyperactivity disorder (ADHD0, obsessive compulsive behaviors, conduct and oppositional defiant disorder, rages, mania, depression, anxiety, panic attacks, phobias, sexual, sleep, and other disorders. Because Tourette syndrome is genetic, this involvement with a spectrum of disorders had broad implications about the causes of behaviors that most mental health workers attributed to psychological problems, poor parenting, or learned behaviors. His genetic studies led him to eventually conclude that Tourette syndrome was a polygenic disorder caused by the coming together from both parents of a number of genes affecting dopamine, serotonin and other brain chemical. Dr. Comings relates how the concept that many human behavioral disorders were genetically interrelated was initially ridiculed. These attitudes began to change as other reported similar findings and as his concept gained support from molecular genetic studies of specific genes."

Tourette's Syndrome--Tics, Obsessions, Compulsions: Developmental Psychopathology and Clinical Care      by James F. Leckman, Donald J. Cohen "Once thought to be rare, Tourette's Syndrome is now seen as a relatively common childhood disorder either in its complete or partial incarnations. Drawing on the work of contributors hailing from the prestigious Yale University Child Psychiatry Department, this edited volume explores the disorder from many perspectives, mapping out the diagnosis, genetics, phenomenology, natural history, and treatment of Tourette's Syndrome."
