Attention-Deficit/Hyperactivity Disorder:
The symptoms of ADHD include inattention and/or hyperactivity and impulsivity. These are traits that most children display at some point or another. But with ADHD, which stands for attention-deficit hyperactivity disorder, or what was referred to as ADD -- attention deficit disorder -- the symptoms are inappropriate for the child's age.
ADHD is common in children and teens. But adults also can have ADHD. With ADHD in adults, there may be some variation in symptoms. For instance, an adult may experience restlessness instead of hyperactivity. In addition, adults with ADHD consistently have problems with interpersonal relationships and employment
Are there different types of ADHD?
There are three different types of ADHD, including:
- combined ADHD (the most common type), which involves all of the symptoms
- inattentive ADHD (previously known as ADD), which is marked by impaired attention and concentration
- hyperactive-impulsive ADHD, which is marked by hyperactivity without inattentiveness
For a diagnosis of ADHD, some symptoms that cause impairment must be present before age seven. Also, some impairment from the symptoms must be present in more than one setting. For instance, the person may be impaired at home and school or home and work. Also, there must be clear evidence the symptoms interfere with the person's ability to function at home, in social environments, or in work environments.
