ABSTRACT
The evaluation of Attention deficit hyperactivity disorder (ADHD) in adults can be a difficult task for multiple reasons. By definition, ADHD has its onset in early life, thereby necessitating a review of symptoms and behaviors during childhood. Corroborated information provided by someone who knew the adult well as a child is often essential. Detailed memories of childhood behavior, particularly in an older adult, can often be difficult to establish. Therefore, the clinician may have to rely on more global descriptions of childhood behavior to assess the presence of the three primary factors of ADHD: inattention, impulsivity, and hyperactivity. For example, a statement such as “He was a really bright child, but he struggled through school and couldn't get the work done” might be an indication of symptoms of inattentiveness.
