What is ADHD?
ADHD stands for Attention Deficit Hyperactivity Disorder (American Psychological Association [APA], 2000). The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) describes ADHD as consisting of three subtypes: (a) Combined, (b) predominantly Hyperactive/Impulsive, and (c) predominantly Inattentive (formerly known as ADD). ADHD-Combined is by far the most prevalent of the three subtypes, ADHD-Inattentive is the second most common, and ADHD-Hyperactive/Impulsive is rather uncommon (APA, 2000). |
