Predominantly hyperactive/impulsive presentation.Ī diagnosis is based on the presence of persistent symptoms that have occurred over a period of time and are noticeable over the past six months.Predominantly inattentive presentation.The observed symptoms are not the result of an individual being defiant or not being able to understand tasks or instructions. These symptoms lead to significant suffering and cause problems at home, at school or work, and in relationships. However, children who meet diagnostic criteria for ADHD, differ in that their symptoms of hyperactivity, impulsivity, organization, and/or inattention are noticeably greater than expected for their age or developmental level. Many children may have difficulties sitting still, waiting their turn, paying attention, being fidgety, and acting impulsively.

Symptoms of ADHD include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought). ADHD is considered a chronic and debilitating disorder and is known to impact the individual in many aspects of their life including academic and professional achievements, interpersonal relationships, and daily functioning (Harpin, 2005).
