Bipolar Disorder in Children and Teens

Condition Basics

Bipolar disorder in children: Overview

Bipolar disorder can appear at any age, but it is very rare in children and teens. Bipolar disorder is sometimes called manic depression. It is an illness that causes extreme mood changes. Moods go from times of very high energy to times of depression. These moods may cause problems with your child's schooling, family life, friendships, and ability to function.

There is no cure for bipolar disorder. But it can be helped with medicines. Counselling may also help. It is important for your child to take any medicines exactly as prescribed, even when they feel well. Your child may need lifelong treatment.

What causes it?

The cause of bipolar disorder isn't completely understood. There are likely many factors involved. It seems to run in families. Your child has a greater risk of having bipolar disorder if a close family member has it. Bipolar disorder can be related to genetics or an imbalance in your child’s hormones. Negative experiences, unsafe or unstable environments, and stressful life events (trauma) can also increase the chances of developing bipolar disorder.

What are the symptoms?

Bipolar disorder causes cycles of mania and depression. Mania is a period of an extremely happy, irritable, or angry mood. Your child may need little sleep and talk very fast. During a depressive episode, your child may have a sad, low, or cranky mood. Your child may have low energy.

How is it diagnosed?

Doctors make the diagnosis by asking about health problems your child and family members have had. The doctor will ask about your child's feelings and behaviour. Your child will also get a physical exam. And the doctor may ask questions to rule out conditions with similar symptoms, like disruptive mood dysregulation disorder (DMDD).

How is bipolar disorder treated?

Bipolar disorder can be managed. Treatment may vary depending on how bad the condition is and your child's age, medical history, and tolerance to medicine. It usually includes medicines (such as mood stabilizers) and counselling. Often a combination of both is needed. To help at home, see that your child gets exercise and has a regular sleep schedule. If your child shows dangerous behaviour, he or she may need to go to the hospital.

Maintaining a healthy lifestyle is also important. Eat healthy foods, have regular routines, and set good habits like regular exercise and managing stress. Join a support group to meet other people who may being experiencing similar concerns. These activities can keep your child motivated and can help to manage their condition better.

Caregivers also experience a lot of stress and emotional challenges. Concerns about their loved one's health can make caregivers forget to take care of themselves. As a caregiver, be mindful of your needs and seek help as needed.

Family support

It's best to build a long-term relationship with your child's care providers. Then when a depressive or manic episode occurs, the care providers can recognize the changes in the child's behaviour and provide quick treatment advice.

If you are a family member of a child with bipolar disorder, it's very important to get the support and help you need. Living with or caring for someone who has bipolar disorder can really disrupt your own life. Manic episodes can be extra tough. It may help to seek your own counsellor or therapist to support you.

Also, some national support organizations may have a local chapter in your area or provide information online. Examples of such groups include the Canadian Mental Health Association and the Mood Disorders Society of Canada.

Examinations and Tests

Doctors make the diagnosis through a combination of:

  • A medical history. The doctor will ask questions to help find other past and present health conditions that could cause the symptoms.
  • A family history. This can identify bipolar disorder, other mood disorders, or a substance use disorder in close relatives. (All of these conditions are linked to bipolar disorder.)
  • A physical exam. It can rule out other conditions with similar symptoms.
  • A mental health assessment. It can help identify your child's current mental state and the severity of depression or mania.
  • Asking questions about your child's feelings and behaviour. And the doctor may ask questions to rule out conditions with similar symptoms, such as disruptive mood dysregulation disorder (DMDD).
  • Other written or verbal mental health tests.

The doctor may do other tests (such as a blood test) to rule out other health problems.

Treatment Overview

The mood changes that come with bipolar disorder can be a challenge. But with the right treatment, they can be managed. Treatment usually includes medicines (such as mood stabilizers) and counselling. Often a combination of both is needed.

Treatment options include:

Make sure your child takes their medicine. Children and teens with this disorder sometimes stop taking their medicines when they feel better. But without medicine, the symptoms usually come back.

Counselling works best when symptoms of bipolar disorder are controlled with medicines.

Home treatment.
This includes helping your child get regular exercise, eat healthy foods, and have a regular sleep schedule.
Hospital treatment.
If your child's behaviour is suicidal, aggressive, reckless, or dangerous, or if they have symptoms of psychosis such as hallucinations, your child may need to go into the hospital for a while.


Learning as much as you can about bipolar disorder may help you recognize mood changes in your child as they start to occur. Catching and treating these mood changes early may help reduce the length of the manic or depressive episode and improve the quality of your child's life.

Here are some steps you can take at home to reduce your child's symptoms and manage your child's moods.

  • Be sure your child gets enough sleep.

    Keep your child's room quiet. And have your child go to bed at the same time every night.

  • Help manage the amount of stress in your child's life.

    You may need to find ways to help your child reduce school requirements during times of severe mania or depression.

  • Recognize early signs of manic and depressive mood episodes.
  • Be sure your child gets enough exercise.

    During a depressive episode, your child may feel like doing only gentle exercises, such as taking a walk or swimming.

  • Be sure your child eats healthy foods.

    Try to avoid beverages that contain caffeine, including coffee, tea, colas, and energy drinks. The Canadian Paediatric Society recommends that children and teens not drink energy drinks. footnote 1

  • Help your child avoid things that may lead to a mood episode.

    Don't let your child use alcohol or drugs. Substance use disorder makes bipolar disorder worse.

  • Ask for help from friends and family when you need it.

Medicines most often used to treat bipolar disorder in children and teens include mood stabilizers, antipsychotics, and antidepressants.

Before prescribing medicine to treat bipolar disorder, your child's doctor will ask questions about possible suicidal behaviour.

When you and the doctor are deciding which types of medicines to use, think about:

  • The side effects of each medicine.
  • How often your child will need to take the medicines.
  • Whether your child is being treated for other illnesses or mental health conditions. How will those medicines interact with medicines for bipolar disorder?
  • Whether your child has used any of the medicines before. Did they work?

Counselling-Based Treatment

Counselling along with medicine can work well to manage bipolar disorder. Types of counselling include:

  • Cognitive behavioural therapy. It focuses on changing certain thinking and behaviour patterns.
  • Family therapy. This helps educate and support the entire family.
  • Dialectical behaviour therapy. This focuses on building skills to manage mood swings.
  • Interpersonal and social rhythm therapy. This focuses on social and family relationships and related problems. It teaches family members about the disorder. They learn how to recognize signs of relapse. And they learn how to manage what creates stress in each family member. This treatment also helps with setting and keeping a regular social and sleep schedule.
  • Talk to your child’s healthcare team and other service providers to learn about groups near you.
