Attention Deficit Hyperactivity Disorder is a mental disorder that commonly affects children and can also be seen to adults. It includes problems on focusing to certain tasks, inattention, hyperactivity and impulsivity. A child can either be inattentive for most of the time, mostly hyperactive and impulsive or a combination of these two symptoms. A person with ADHD may have difficulty in concentrating, paying attention or following instructions, remembering details, staying organized, controlling impulses when certain emotions arise and even staying still is a challenge for them.
