ADHD and Tourette Syndrome are Spectrum Disorders associated with a wide range of associated behavioral problems including learning disorders, dyslexia, oppositional defiant behaviors, depression and others. Dr. Comings reviews the epidemiological data indicating that these disorders are increasing in frequency and affecting people at a younger age. Each of these conditions has a strong genetic basis. The story is presented of why the dramatic increase in the number of individuals attending college in the later half of the 20th century may be resulting in the rapid selection for the genes causing these conditions. This important theory has broad implication for public policy - as well as the future of the human species.From the Author:
Many studies have shown a significant increase in a range of behavioral disorders in the 20th century. These include autism, learning disorders, depression, conduct disorder and others. These trends have often been attributed to immunizations, crowed schools, poor teachers, a more complex society, poor parental control and others. However, each of these entities has a strong genetic component and an alternative explanation is that the relevant gene variants are increasing in frequency. This book shows how the introduction of the contraceptive pill and the dramatic increase in number of individuals attending college over the past century can provide a mechanism for driving the selection of these genes. This issues are important for public policy. If the correct cause of these trends is not identified, throwing billions of dollars at them or altering important health programs, would be without effect.
