American Psychiatric Association diagnostic criteria for ADHD includes:
- Symptoms must persist for at least six months
- Symptoms must be present in more than one setting (e.g., school and home)
- Symptoms must impair function in academic, social, or occupational activities
- Symptoms must be present before the age of 12 years
- Symptoms must be excessive for the age of the child
- Other mental disorders that could account for the symptoms must be excluded
What Is the Treatment for ADHD?
Treatment for ADHD (attention deficit hyperactivity disorder), is usually a combination of behavior therapy and medication. Medications do not cure ADHD, and behavioral treatments are usually needed to help a child learn to follow rules, stay motivated, and work well with others.
Behavioral treatments are recommended for preschool-aged children before medications are prescribed. School-aged children with ADHD usually do well with a stimulant medicine plus behavioral treatments and counseling if needed.
Medications used to treat ADHD include:
- Stimulants
- Methylphenidate (Concerta, Focalin, Metadate, Methylin, Ritalin, Daytrana)
- Amphetamines (Adderall, Dexedrine, Dextrostat, Vyvanse)
- Atomoxetine (Strattera) is a nonstimulant medicine used as an alternative
Behavioral treatments for ADHD include:
- Maintaining a schedule
- Setting reachable and clear goals
- Providing specific places for the child to keep school work, toys, and clothes
- Keeping distractions to a minimum
- Rewarding positive behavior
- Limiting choices
- Using charts and checklists to help the child stay focused on the task at hand
- Taking physical activity breaks during tasks that require attention
- Finding activities such as sports or hobbies where the child can be successful
- Using calm discipline such as time outs, distractions, or removing the child from the situation
