Attention Deficit Hyperactivity Disorder and Attention Deficit Disorder
(ADHD and ADD; Hyperkinetic Syndrome; Hyperkinetic Impulse Disorder)En Español (Spanish Version)More InDepth Information on This Condition
Attention deficit hyperactivity disorder (ADHD) is a chronic behavioral disorder. It is behavior that is hyperactive, impulsive, and/or inattentive. These must persist for at least six months and be present in two environments (home, work, or school). ADHD affects children, adolescents, and adults.
The cause of ADHD is unknown. It most likely is caused by a chemical imbalance in the brain. There also appears to be a genetic factor since ADHD can run in families.

A risk factor increases your chance of getting a disease or condition.
Risk factors for ADHD are:
- Sex: male
- Parent or sibling with ADHD
All children display some of the symptoms of ADHD. Children with ADHD have symptoms that are more severe and consistent. They often have difficulty in school and with their family and peers.
ADHD can last into adulthood. It can cause problems with relationships, job performance, and job retention.
There are three types of ADHD:
- Inattentive (classic "ADD")
Inattentive (Classic "ADD")
- Easily distracted by sights and sounds
- Doesn't pay attention to detail
- Doesn't seem to listen when spoken to
- Makes careless mistakes
- Doesn't follow through on instructions or tasks
- Avoids or dislikes activities that require longer periods of mental effort
- Loses or forgets items necessary for tasks
- Is forgetful in day-to-day activities
- Is restless, fidgets, and squirms
- Runs and climbs and is not able to stay seated
- Blurts out answers before hearing the entire question
- Has difficulty playing quietly
- Talks excessively
- Interrupts others
- Has difficulty waiting in line or waiting for a turn
There is no standard test to diagnose ADHD. It is done by a trained mental health professional. Family and teachers are involved as well.
The American Academy of Pediatrics recommends that the following guidelines be used for diagnosis in children 6-12 years of age:
Diagnosis should be initiated if a child shows signs of difficulty in:
- Academic achievement
- Relationships with peers and family
During diagnosis, the following information should be gathered directly from parents, caregivers, teachers, or other school professionals:
- Assessment of symptoms of ADHD in different settings (home and school)
- Age at which symptoms started
- How much the behavior affects the child's ability to function
The professional should examine the child for:
- Other conditions that might be causing or aggravating symptoms
- Learning and language problems
- Disruptive behavior
- Depression or anxiety
- Psychotic symptoms
- Personality disorder
For a diagnosis of ADHD to be made, symptoms must:
- Be present in two or more of the child's settings
- Interfere with the child's ability to function for at least six months
- Fit a list of symptoms detailed in the most recent version of the Diagnostic and Statistical Manual (DSM) of the American Psychiatric Association
The goal is to improve the child's ability to function. Doctors should work together with parents and school staff. Together, they can set realistic goals and evaluate the child's response.
Medications can help control behavior and increase attention span. Stimulants are the most common choice for ADHD. They increase activity in parts of the brain that appear to be less active in children with ADHD. Stimulant medications include:
- Methylphenidate (Ritalin, Concerta, Metadate, Daytrana)
- Dextroamphetamine (Dexedrine)
- Amphetamine (Adderall)
- Atomoxetine (Strattera)
- Lisdexamfetamine dimesylate (Vyvanse)—This medication was recently approved to treat adults with ADHD. It can also be used to treat children aged 6-12 years. *²
Talk to your doctor if you have any questions about ADHD medication. There are possible risks with these medications, including cardiovascular events (eg, stroke , heart attack ) and psychiatric problems (eg, hearing voices, becoming manic).
Other drugs include:
- Antidepressants—such as imipramine (Janimine, Tofranil), venlafaxine (Effexor), and bupropion (Wellbutrin)
- Clonidine (used for Tourette's syndrome )—to treat impulsivity
Children who take medication and practice therapy do better than those who just use medication. Therapy sessions focus on practicing social and problem-solving skills. Counselors will also teach parents and teachers to help the child through positive reinforcement. This could involve change in the classroom as well as in parenting style. Often, daily report cards are exchanged between parents and teachers.
