ADD/ADHD is not as easily diagnosed or clear-cut as many believe; in fact it very often acts as a masking agent for other underlying, contributing disorders. This volume is the culmination of the author's years of research involving clinical experience and testing. Debunking common myths and shedding light upon the way this disorder truly impacts people, the book presents the results of the largest clinical research study for ADD/ADHD, compiling 20 years of testing. The book provides statistical analysis from neuropsychological evaluations and self-reporting questionnaires from parents, teachers, adolescents, and adults.
