Attention-Deficit Hyperactivity Disorder (ADHD)

Attention-deficit hyperactivity disorder (ADHD) is a neurologically-based disorder characterized by inattentiveness, hyperactivity, impulsivity, disorganization, or a combination of these behaviors, which is present in multiple settings (e.g., school, home, work, church, etc.). Children with ADHD are typically much more active or impulsive than what is usual for their age. These behaviors contribute to significant problems in relationships, learning, and behavior. For this reason, children who have ADHD are sometimes seen as being “difficult” or as having behavior problems. People who have ADHD often have problems getting along with other people because they may have difficulty controlling impulses.

ADHD is more prevalent in boys than girls, although some believe that girls are under-diagnosed as some may not display hyperactive or impulsive behaviors the same as boys. You may be more familiar with the term attention deficit disorder (ADD). This disorder was renamed in 1994 by the American Psychiatric Association (APA).

A thorough evaluation is usually necessary for proper diagnosis. Although some psychiatrists and physicians will diagnose and medicate upon observance of symptoms, medication without a proper differential diagnosis is not best practice, especially because symptoms of other psychiatric disorders or educational issues such as anxiety or a learning disability may present similar to ADHD.
