Children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) frequently experience co-occurring problems with aggression, mood swings, tics, anxiety, or depression. Organized around detailed case presentations, this highly informative book helps the clinician make sound decisions when assessing and treating the full range of ADHD comorbidities. Experienced child psychiatrist Steven Pliszka offers straightforward guidance on how to avoid common diagnostic errors, develop an individualized medication regimen, minimize health risks and side effects, collaborate successfully with parents, and tailor psychosocial treatments to each family's needs. A reproducible structured interview facilitates sorting out symptoms and distinguishing between different comorbid disorders. This book will be crucial for clinicians who treat children with ADHD, including clinical psychologists, child psychiatrists, social workers, pediatricians, and school psychologists. It may also serve as a text in clinically oriented graduate courses and residency programs.
