What is attention deficit hyperactivity disorder (ADHD)?

Attention deficit hyperactivity disorder (ADHD), also referred to by some as attention deficit disorder (ADD), is classified as a behavioral disorder that has neurocognitive issues involved. The symptoms of this disorder have been described in the known medical literature for at least the past 200 years. ADHD is characterized by problems focusing, sitting still, and/or controlling impulses.

What is the impact of ADHD in adults?

Adults affected by ADHD can be challenged in their ability to make and keep friends and other relationships, do well in school, at work, and/or in the community in general. Early treatment of ADHD may prevent a number of further problems from developing during adulthood. While men with this condition tend to develop substance-abuse disorders more often than women with the condition, men and women tend to have trouble getting and keeping jobs at an equal rate.

How common is ADHD in adults?

ADHD is quite common. Among school-aged children, this disorder has been found to occur from 2%-20%, translating to 4.5 million children 3 to 17 years of age. The onset of the disorder for most individuals is usually sometime during the school-age years. While boys are still thought to develop this illness more often than girls, improved assessment of girls has resulted in the gender gap in diagnosis being significantly less than in years past. Up to about 60% of children with ADHD grow into adults with continued challenges as a result of the disorder.

Approximately 1%-6% of adults are estimated to have ADHD. In adults, women are thought to suffer from ADHD at a rate that is much closer to equal compared to men.

What are common adult ADHD symptoms, behaviors, and problems?

People with adult ADHD may have lower self-esteem than adults without this disorder. Some studies on adults with ADHD show that more than two-thirds may have another mental health condition, and about 50% have two other such conditions. The most common other problems that adults with ADHD suffer from include drug abuse and addiction, and mood, anxiety, and personality disorders. In terms of personality disorders, adults with ADHD are at risk for developing antisocial personality disorder and borderline personality disorder. More than one-third of adults with ADHD need adult mental health treatment.

How is ADHD diagnosed in adults?

Like children, adults who suspect they have ADHD should be evaluated by a licensed mental health professional. But the professional may need to consider a wider range of symptoms when assessing adults for ADHD because their symptoms tend to be more varied and possibly not as clear cut as symptoms seen in children.

To be diagnosed with the condition, an adult must have ADHD symptoms that began in childhood and continued throughout adulthood.15 Health professionals use certain rating scales to determine if an adult meets the diagnostic criteria for ADHD. The mental health professional also will look at the person's history of childhood behavior and school experiences, and will interview spouses or partners, parents, close friends, and other associates. The person will also undergo a physical exam and various psychological tests.

For some adults, a diagnosis of ADHD can bring a sense of relief. Adults who have had the disorder since childhood, but who have not been diagnosed, may have developed negative feelings about themselves over the years. Receiving a diagnosis allows them to understand the reasons for their problems, and treatment will allow them to deal with their problems more effectively.
