Attention deficit hyperactivity disorder (ADHD) is not limited to children. Between 30% and 70% of children diagnosed with ADHD continue showing symptoms into adulthood. In some cases, adults who were never diagnosed as kids may develop more obvious symptoms in adulthood, causing problems with work and relationships. Some adults don’t realize they have ADHD, which can leave them confused about their behaviour and inability to reach goals in life.

An adult ADHD doctor is often a primary care doctor, psychiatrist or psychologist. To diagnose ADHD in adults, a doctor will often require a history of the adult’s behavior as a child as well as speaking with the patient’s spouse, partner, and friends. By examining the person’s records and anecdotal information they can determine whether they are showing ADHD symptoms. The doctor may also use psychological tests and other evaluation methods to reach an ADHD diagnosis.
