Attention Deficit Hyperactivity Disorder is a common condition that affects both children and adults, and can have serious consequences for academic, emotional, social, and occupational functioning. When properly identified and diagnosed, however, there are many interventions for the disorder that have established benefits. This volume provides therapists with practical, evidence-based guidance on diagnosis and treatment from leading experts — and does so in a uniquely "reader-friendly" manner. Readers will gain an understanding of recent advances in the etiology and symptom presentations of ADHD in children and adults, as well as the use of stimulant medications, other psychopharmacological approaches, and psychotherapeutic interventions.
