Attention Deficit Hyperactivity Disorder (ADHD) is a medical disorder not of attention, but of self-regulation. Understanding who might have ADHD and what to do about it can impact a person's entire future. When is ADHD over-diagnosed – and where might it be under-diagnosed? What are common symptoms beyond focus, impulsivity, and hyperactivity, and how does ADHD relate to the development of executive function? And why does ADHD impact everything from academics to stress, obesity to peer relations? This lecture includes the latest research into both medical and non-medical treatments of ADHD, as well as signs that may indicate adults have it ... or do not. It covers an overview of diagnosis, common conditions that occur along with ADHD, and research-based medical, behavioral, educational and complementary care.
