From a trusted expert in the field, this authoritative work provides an accessible overview of what learning disorders are, how they develop, and how to diagnose and treat them effectively. The second edition has now been substantially revised and expanded to reflect significant clinical and research advances. The author presents the most current neuroscientific knowledge on a range of conditions, including dyslexia, autism spectrum disorders, attention-deficit/hyperactivity disorder, and others. Practitioners gain vital insights and tools for making sense of children's impairments and strengths, collecting and interpreting diagnostic data from a variety of sources, and linking diagnosis to evidence-based interventions.This edition covers additional disorders: intellectual disability, mathematics disorder, and developmental coordination disorder, plus a chapter on less well-validated disorders. There are new case illustrations and a focus on empirically based practice. It is now grounded in a multiple cognitive-deficit model of learning disorders, replacing the prior edition's modular, single-deficit model. A new chapter on controversial therapies separates myths from facts.
