Since IDEA does not define ADHD, which organization provides the working definition of ADHD?

• A. Centers for Disease Control and Prevention
• B. American Medical Association
• C. American Psychiatric Association
• D. National Institute of Health

Answer: (C)

The American Psychiatric Association provides the working definition of ADHD (Attention-Deficit/Hyperactivity Disorder) through its Diagnostic and Statistical Manual of Mental Disorders (DSM). This manual is widely used by mental health professionals for diagnosing mental disorders, including ADHD, and outlines the criteria needed for an official diagnosis.

While other organizations like the Centers for Disease Control and Prevention, the American Medical Association, and the National Institute of Health may provide valuable information and resources regarding ADHD, they do not establish the diagnostic criteria used in clinical practice. The American Psychiatric Association's definition is recognized as the authoritative standard, making it essential for understanding how ADHD is categorized and treated in both educational and health contexts.
