Condition Basics

What is attention deficit hyperactivity disorder (ADHD)?

Attention deficit hyperactivity disorder (ADHD) is a common condition. A person who has ADHD has trouble paying attention and focusing on tasks, tends to act without thinking, and has trouble sitting still.

It may begin in early childhood and can continue into adulthood. ADHD can be treated with behaviour therapy, medicines, and counselling. Treatment can improve your life.

In the past, ADHD was called attention deficit disorder (ADD).

What causes it?

The exact cause of ADHD is not clear, but it tends to run in families. Ongoing research is focused on finding the genes that may make a person more likely to get ADHD. Although many parents believe that foods with sugar and food additives make their children more hyperactive, these foods haven't been shown to cause ADHD.^{footnote 1}

What are the symptoms?

ADHD is a condition that makes it hard to pay attention. People with ADHD also may be more active than normal and tend to act without thinking. ADHD may make it harder to focus, get organized, and finish tasks.

How is it diagnosed?

A doctor relies on a combination of examinations, tests, and other information to diagnose ADHD. It is often diagnosed when a child is between 6 and 12 years old. Parents and teachers may first notice symptoms in children who are in this age group.

How is ADHD treated?

Treatment for ADHD will depend on the age of the person. It may include behaviour therapy and medicines. The first step is an accurate diagnosis of ADHD and an understanding of the person's strengths and weaknesses. There is no cure for ADHD, but treatment may help control the symptoms.

Symptoms

ADHD can cause three types of symptoms:

Trouble paying attention (inattention).

People with ADHD often have a hard time focusing on any one task.

Trouble sitting still for even a short time (hyperactivity).

Children with ADHD may squirm, fidget, or run around at the wrong times. Teens and adults often feel restless and fidgety. They aren't able to enjoy reading or other quiet activities. Most people with ADHD are hyperactive only some of the time, even if hyperactivity is their main symptom.

Acting before thinking (impulsivity).

People with ADHD may talk too loud, laugh too loud, or become angrier than the situation calls for. Children may not be able to wait for their turn or to share. This makes it hard for them to play with other children. Teens and adults may make quick decisions that have a long-term impact on their lives. They may spend too much money or change jobs often.

What Happens

ADHD most often starts in childhood and can last into adulthood.

It can be hard to tell the difference between normal behaviour and ADHD symptoms in young children. But after a child starts school, ADHD becomes more noticeable. It is most often diagnosed in children ages 6 to 12. During this time, it can disrupt many aspects of a child's life. Learning, adjusting to change, sleeping, and making friends are all areas where children with ADHD may need extra help.

Adults with ADHD may continue to have trouble focusing, organizing, and finishing tasks. But they are often able to adjust to the workplace better than they did in the classroom as children.

When to Call a Doctor

Call a doctor if:

• Your child is showing signs of ADHD that are causing problems at home or school. These signs include inattention, impulsivity, and/or hyperactivity. Parents and teachers often notice this behaviour during the child's first few years in school.
• Your child shows signs of other mental health disorders, such as depression or anxiety, that last more than a few weeks or seem to be getting worse.
• Your child is having academic or behavioural problems at school.

Examinations and Tests

A doctor uses a combination of examinations, tests, and other information to check for ADHD. The diagnosis will be based on:

• A talk with your child.
• Your child's medical history. The doctor will ask about your child's social, emotional, educational, and behavioural history.
• A physical examination.
• Behaviour rating scales or checklists for ADHD. These are used by parents and teachers to evaluate your child's symptoms.

Before meeting with your doctor, think about at what age your child's symptoms began. You and other caregivers can help by recording when the behaviour occurs and how long it lasts. An important part of checking for ADHD is thinking about the kinds of problems caused by the behaviours. How much do they affect schooling and social behaviour?

Treatment Overview

Treatment for ADHD will depend on the age of the person. It may include behaviour therapy and medicines. The first step is an accurate diagnosis of ADHD and an understanding of the person's strengths and weaknesses. There is no cure for ADHD. But treatment may help control the symptoms.

With behaviour therapy:

• Parents learn strategies, such as positive reinforcement, to improve a child's behaviours.
• Children learn skills for problem solving, communication, and self-advocacy.

Behaviour therapy is more helpful when used with medicine than when used by itself.

Medicines that may be used for ADHD include:

Stimulant medicines.

One example is amphetamine (for example, Adderall XR). Another is methylphenidate (for example, Concerta or Ritalin).

Non-stimulant medicines.

Examples are atomoxetine (Strattera), clonidine, or guanfacine (Intuniv). These medicines may be used if stimulant medicines aren't effective or have side effects that bother the person. They may be used alone. Or they may be use in combination with stimulant medicines.

Caring for your teen

Regular, open communication with your teen and your teen's teachers and doctors is the first step in helping your teen with ADHD to thrive. And being aware of what's happening in your teen's life will allow you to work together to solve problems that might occur.

The teen years present many challenges. These include more schoolwork and the need to be more attentive and organized. Making good decisions becomes more important during these years when peer pressure, sexuality, and other issues surface.

Work with your teen to create reasonable goals. And use the right consequences when goals aren't met. That may include losing privileges or having more chores at home. Allow your teen to help decide rewards when the goals are met.

Medicines are used to help control the symptoms of ADHD.

Children should be closely watched after they start medicines. The doctor can assess if your child is getting the right dose.

Be sure that medicine for ADHD is taken on schedule. You'll also need to keep track of the effects of the medicine. Talk often with your child's doctor.

Medicines to treat ADHD include:

• Stimulants. Examples are amphetamine (such as Adderall or Dexedrine) and methylphenidate (such as Concerta or Ritalin).

Most often, stimulants are used to treat ADHD. These work well for people of all ages. In general, stimulants improve symptoms quickly.

If stimulants don't work or have side effects that cause problems, your child's doctor might recommend a non-stimulant. These medicines may be used alone or along with stimulant medicines.
