ADD; ADHD; Childhood hyperkinesis
Attention deficit hyperactivity disorder (ADHD) is a problem caused by the presence of one or more of these findings:
ADHD often begins in childhood. But it may continue into the adult years. ADHD is diagnosed more often in boys than in girls.
It is not clear what causes ADHD. It may be linked to genes and home or social factors. Experts have found that the brains of children with ADHD are different from those of children without ADHD. Brain chemicals are also different.
ADHD symptoms fall into three groups:
Some people with ADHD have mainly inattentive symptoms. Some have mainly hyperactive and impulsive symptoms. Others have a combination of these behaviors.
INATTENTIVE SYMPTOMS
HYPERACTIVITY SYMPTOMS
IMPULSIVITY SYMPTOMS
Many of the above findings are present in children as they grow. For these problems to be diagnosed as ADHD, they must be out of the normal range for a person's age and development.
There is no test that can diagnose ADHD. Diagnosis is based on a pattern of the symptoms listed above. When a child is suspected to have ADHD, parents and teachers are often involved during the evaluation.
Most children with ADHD have at least one other developmental or mental health issue. This may be a mood, anxiety, or substance use disorder. Or, it may be a learning issue or a tic disorder.
Treating ADHD is a partnership between your health care provider and the person with ADHD. If it's a child, parents and often teachers are involved. For treatment to work, it is important to:

MEDICINES
Medicine combined with behavioral treatment often works best. Different ADHD medicines can be used alone or combined with each other. Your provider will decide which medicine is right, based on your child's symptoms and needs.
Psychostimulants (also known as stimulants) are the most commonly used medicines. Although these medicines are called stimulants, they actually have a calming effect on people with ADHD. Other medicines that are not stimulants are FDA approved for some people with ADHD. Ask your provider what is best for you.
Follow your provider's instructions about how to take ADHD medicine. Your provider needs to monitor if the medicine is working and if there are any problems with it. So, be sure to keep all appointments with your provider.
Some ADHD medicines have side effects. If you or your child has side effects, contact your provider right away. The dosage or medicine itself may need to be changed.
THERAPY
A common type of ADHD therapy is called behavioral therapy. It teaches children and parents healthy behaviors and how to manage disruptive behaviors. For mild ADHD, behavioral therapy alone (without medicine) may be effective.
Other tips to help a child with ADHD include:
There is little proof that alternative treatments for ADHD such as herbs, supplements, and chiropractic treatments are helpful.
