Attention-Deficit / Hyperactivity Disorder (AD/HD) is a neurodevelopmental disorder characterized by a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development. For purposes of diagnosis, the disorder is broken down into three subtypes based on the predominant symptom.

AD/HD, predominantly inattentive presentation is characterized by symptoms of inattention (but fewer than six symptoms of hyperactivity-impulsivity) that have persisted for at least six months. This is the disorder most people are referring to when they use the old term Attention-Deficit Disorder (ADD). Children who are inattentive have a hard time keeping their minds on any one thing and may get bored with a task after only a few minutes. If they are doing something they really enjoy, they have no trouble paying attention. But focusing deliberate, conscious attention to organizing and completing a task or learning something new is difficult.

AD/HD, predominantly hyperactive/impulsive presentation is characterized by symptoms of hyperactivity-impulsivity (but fewer than six symptoms of inattention) that have persisted for at least six months. Hyperactive children always seem to be “on the go” or constantly in motion. They dash around touching or playing with whatever is in sight, or talk incessantly. Sitting still at dinner or during a school lesson or story can be a difficult task. They squirm and fidget in their seats or roam around the room. Or they may wiggle their feet, touch everything, or noisily tap their pencil. Hyperactive teenagers or adults may feel internally restless. They often report needing to stay busy and may try to do several things at once.

AD/HD, combined presentation is characterized by more than six symptoms of both inattention and hyperactivity-impulsivity that have persisted for at least six months. Most children and adolescents diagnosed with AD/HD have the combined type
