ADHD is a neurodevelopmental disorder characterized by significant difficulty paying attention and/or hyperactive/impulsive behaviors that impairs functioning across multiple settings. The diagnosis of ADHD is rarely given until a child is around 5 or 6 years of age, as these symptoms are a normal part of development in young children.

There are three types of ADHD:

• Predominately inattentive presentation, which is characterized by difficulty paying attention, focusing, listening to instructions, etc.

• Hyperactive/impulsive presentation, which is characterized by over activity, interrupting, blurting out, difficulty staying seated, etc.

• Combined presentation (the most common type of ADHD), which is characterized by significant symptoms of inattention and hyperactivity/impulsivity
