Attention deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, with effects on academic and occupational performance, social relationships, and other aspects of functioning. Neuropsychologists frequently work with both children and adults with ADHD, and understanding the relevant scientific literature is an important part of training and continuing education in our field. In this episode, John and Ryan talk to Dr. Robb Mapou about ADHD, including conversations on developmental course, co-occurring symptoms, assessment, diagnosis, and treatment, among other topics.
