Alarmed by this trend, family therapist Marilyn Wedge set out to understand how ADHD became an American epidemic. If ADHD were a true biological disorder of the brain, why was the rate of diagnosis so much higher in America than it was abroad? Was a child's inattention or hyperactivity indicative of a genetic defect, or was it merely the expression of normal behavior or a reaction to stress? Most important, were there alternative treatments that could help children thrive without resorting to powerful prescription drugs? In an effort to answer these questions, Wedge published an article in Psychology Today entitled "Why French Kids Don't Have ADHD" in which she argued that different approaches to therapy, parenting, diet, and education may explain why rates of ADHD are so much lower in other countries.

In A Disease Called Childhood, Wedge examines how myriad factors have come together, resulting in a generation addictied to stimulant drugs, and a medical system that encourages diagnosis instead of seeking other solutions. Writing with empathy and dogged determination to help parents and children struggling with an ADHD diagnosis, Wedge draws on her decades of experience, as well as up-to-date research, to offer a new perspective on ADHD. Instead of focusing only on treating symptoms, she looks at the various potential causes of hyperactivity and inattention in children and examines behavioral and environmental, as opposed to strictly biological, treatments that have been proven to help. In the process, Wedge offers parents, teachers, doctors, and therapists a new paradigm for child mental health--and a better, happier, and less medicated future for American children
