Thomas E. Brown

Thomas E. Brown, Ph.D. (1942–2025) was a clinical psychologist and internationally recognized expert on attention-deficit/hyperactivity disorder (ADHD), particularly its impact on executive function and emotion. He earned his Ph.D. in clinical psychology from Yale University, where he served on the faculty in the Department of Psychiatry for roughly two decades while working in the Yale Clinic for Attention and Related Disorders. He later became director of the Brown Clinic for Attention and Related Disorders in Manhattan Beach, California, and held academic appointments including adjunct clinical associate professor of psychiatry and behavioral sciences at the Keck School of Medicine of the University of Southern California and clinical professor of psychiatry and neuroscience at the University of California, Riverside.

Brown authored seven books and numerous articles on ADHD, helping to reframe it as a disorder of executive function and to highlight the central role of emotions in how ADHD affects daily life. His works include Smart But Stuck: Emotions in Teens and Adults with ADHD, A New Understanding of ADHD in Children and Adults, Attention Deficit Disorder: The Unfocused Mind in Children and Adults, Outside the Box: Rethinking ADD/ADHD in Children and Adults, and *ADHD
