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.
Forward: "It is at once a detective story, a scientific essay, and a study in the folly of human nature. It is also a love-story. The book lays bare to the reader all the intrigue and meticulous care that occupy the life of a professional gene hunter, as Dr. Comings recounts the history of his latest foray into uncharted territory of the human genome. He was, and is, a hard scientist who got caught by his work as a clinician. David Comings moved into the study of Tourette syndrome, this strange condition of twitching and shouting, after a long and illustrious career exploring the genetics of better-understood, more clear-cut problems. He and others had long been convinced that there was a simple, straightforward genetic basis for this disorder."
