ADHD is one of the most commonly identified disorders of early childhood. It can be misdiagnosed in young children (under 6), as most experience some degree of difficulty regulating their attention and behavior from time to time. Behaviors associated with ADHD may look similar to those related to other childhood challenges, making a thorough evaluation important.
There is no single test to identify ADHD. Determining if a child has ADHD is a multiple-step process. The first step is to rule out possible underlying physical causes for the symptoms.
