Among the first comprehensive texts devoted specifically to educating nurse practitioners about Attention-Deficit/Hyperactivity Disorder (ADHD), this work addresses a critical gap in clinical training by focusing on evidence-based assessment and treatment across the lifespan. It provides practical guidance for clinicians working with pediatric, adolescent, and adult populations

Written by an interdisciplinary group—including university professors, national ADHD organization leaders, and experienced clinicians such as nurse practitioners, social workers, therapists, and ADHD coaches—the book presents a multidisciplinary perspective on ADHD care.

Chapters cover screening, a comprehensive assessment, diagnostic formulation, and treatment planning, including both pharmacologic and non-pharmacologic interventions. Case examples illustrate real-world clinical application and highlight nurse practitioner–led models of care. The text also addresses telehealth delivery, legal and regulatory considerations, health disparities, and the integration of ADHD education into undergraduate and graduate nursing curricula.
