What is bipolar disorder?
Bipolar disorder is an illness that causes extreme mood changes from manic episodes of very high energy to the extreme lows of depression. It is also called manic-depressive disorder.
This illness can cause behaviour so extreme that you cannot function at work, in family or social situations, or in relationships with others. Some people with bipolar disorder become suicidal.
About 1% of the population, or 1 out of 100 people, have bipolar disorder.footnote 1
It's important to know that you're not alone. Talking with others who suffer from bipolar disorder may help you learn that there is hope for a better life. And treatment can help you get back in control.
What causes bipolar disorder?
The cause of bipolar disorder isn't completely understood. It tends to run in families. It may also be affected by your living environment or family situation. One possible cause is an imbalance of chemicals in the brain.
What are the symptoms?
The symptoms depend on your mood swings, or "highs" and "lows." During a manic high, you may feel:
- Very happy, energetic, or on edge.
- Like you need very little sleep.
- Overly self-confident.
Some people spend a lot of money or get involved in dangerous activities when they are manic. After a manic episode, you may return to normal. Or your mood may swing in the opposite direction to feelings of sadness, depression, and hopelessness. During a depressive episode, or low, you may have:
- Trouble thinking and making decisions.
- Memory problems.
- Less interest in things you have enjoyed in the past.
- Thoughts about killing yourself.
The mood swings of bipolar disorder can be mild or extreme. They may come on slowly over several days or weeks or suddenly over a few minutes or hours. These mood swings may last for a few hours or for several months.
How is bipolar disorder diagnosed?
Bipolar disorder is hard to diagnose. First, your doctor or therapist will ask detailed questions about what kind of symptoms you have and how long they last. Your urine and blood may be tested to rule out other problems that could be causing your symptoms.
There are two types of bipolar disorder: I and II.
To be diagnosed with bipolar I disorder, you must have had:
- A manic episode lasting at least a week (or less, if you had to be hospitalized).
- During that time, three or more symptoms of mania, such as needing less sleep or feeling as if your thoughts are racing.
For bipolar II disorder, your doctor will look for the same symptoms, but the manic high may be less severe and shorter.
How is it treated?
Bipolar disorder is treatable. With treatment, which includes medicines and counselling, you can feel better.
You may need to try several medicines to find the combination that works for you.
- Most people with bipolar disorder need to take a medicine called a mood stabilizer every day.
- Medicines called antipsychotics can help get a manic phase under control.
- Antidepressants are used carefully for episodes of depression, because they cause some people to move into a manic phase.
Counselling for you and your family is also an important treatment. It can help you cope with some of the work and relationship issues that the illness may cause.
You can do a few things on your own to help deal with bipolar disorder. These include regular activity, getting enough sleep, and learning to recognize early signs of highs and lows.
People often stop taking their medicines during a manic phase because they feel good. But this is a mistake. You must take your medicines regularly, even if you are feeling better.
Health Tools help you make wise health decisions or take action to improve your health.
The cause of bipolar disorder is not well understood, but evidence suggests that it runs in families.footnote 2 Your living environment and family situation may also play a role. Episodes of depression and mania may be caused by a problem with certain brain chemicals called neurotransmitters.
Antidepressant medicines can trigger a manic episode in a person who has bipolar disorder. But this may occur before the person is diagnosed, while he or she is seeking treatment for an episode of depression.
Sleep deprivation or substance abuse, including caffeine, can cause a person with bipolar disorder to have a manic episode.
Bipolar disorder causes extreme mood swings, from feeling overly energetic (mania) to feeling very sad or having low energy (depression).footnote 2
Mania may make you:
- Feel extremely happy or very irritable.
- Not need as much sleep as usual. (You may feel rested after 3 hours of sleep.)
- Talk more than usual.
- Be more active than usual.
- Have trouble concentrating because of having too many thoughts at the same time (racing thoughts).
- Act impulsively or do reckless things, such as go on shopping sprees, drive recklessly, or get into foolish business ventures. Or you may have frequent, indiscriminate, or unsafe sex.
Depression may make you:
- Feel sad or anxious for a significant period of time.
- Have slowed thoughts and speech because of low energy.
- Have trouble concentrating, remembering, and making decisions.
- Have changes in eating and sleeping habits. You may eat or sleep too much or too little.
- Have less interest in your usual activities, including sex.
- Have suicidal thoughts.
Types of bipolar disorder
- Bipolar I. This is the classic form of the illness. It causes episodes of mania and depression that keep coming back. The depression may last for a short time or for months. You may then go back to feeling normal for a time, or you may go right into a manic high.
- Bipolar II. With this form, you will have depression just as in bipolar I. But the manic highs are less severe (hypomania). People with bipolar II have more depressive lows than hypomanic highs.
Some people may have bipolar disorder with mixed symptoms. Their highs and lows of mania and depression occur together. This makes the disorder challenging to treat and very frustrating for you and for those around you. It can also lead to hospitalization if your daily functioning becomes impaired.
If you have rapid-cycling bipolar disorder, you may have at least four episodes of depression, mania, or both within a 12-month period. You may go directly from a low to a high. Or you may have a short time lapse between the two extreme moods.
With bipolar disorder, you go back and forth between highs and lows of mania and depression. In between, you may return completely to normal or have some remaining symptoms. The extreme mood changes may come on suddenly or appear more slowly.
During a manic episode, you may go from feeling abnormally happy and productive to behaving irresponsibly and sleeping very little. After this manic high, your mood may return to normal. Or it may swing in the opposite direction. You may feel useless and extremely sad. And you may lose interest in things you've enjoyed in the past.
Men tend to have more manic highs, and women tend to have more lows of depression.footnote 3
At first, stress may trigger depression or mania. But as the illness progresses, mood swings may not be caused by any specific event. Without treatment, your bipolar disorder may get worse. This can cause you to move more often between mania and depression.
Other health problems
People with bipolar disorder—men more often than women—may have substance use problems, especially during manic episodes.footnote 4 Heavy use of alcohol or drugs may affect treatment and interfere with taking medicines as prescribed. Other disorders that may occur along with this disorder include:footnote 5
These illnesses need to be treated along with bipolar disorder.
What Increases Your Risk
Bipolar disorder can be passed down through families. If anyone in your family has been diagnosed with bipolar disorder, your risk of having it is higher.
Some things can increase your risk of a manic episode or depression. These include:
- Changes in sleep or daily routines.
- Antidepressant medicine. This can happen if you haven't been diagnosed with bipolar disorder and are seeking treatment for depression.
- Stressful events.
- Quitting your medicine for bipolar disorder. Even if you're feeling better, it's important to take your medicines as prescribed.
Alcohol or drug use or abuse puts you at a high risk for having a relapse of mood disturbances.footnote 5
When To Call a Doctor
Call 911, your provincial health information line, or other emergency services right away if:
- You or someone you know is thinking seriously of suicide or has recently tried suicide. Serious signs include these thoughts:
- You have decided how to kill yourself, such as with a weapon or medicines.
- You have set a time and place to do it.
- You think there is no other way to solve the problem or end the pain.
- You feel you cannot stop from hurting yourself or someone else.
Call a doctor right away if:
- You hear voices.
- You have been thinking about death or suicide a lot, but you do not have a plan for suicide.
- You are worried that your feelings of depression or thoughts of suicide aren't going away.
Seek care soon if:
- You have symptoms of depression, such as:
- Feeling sad or hopeless.
- Not enjoying anything.
- Having trouble with sleep.
- Feeling guilty.
- Feeling anxious or worried.
- You have been treated for depression for more than 3 weeks, but you aren't getting better.
Who to see
Bipolar disorder is complex and hard to diagnose, because it has many phases and symptoms. Sometimes it is misdiagnosed as only depression, because people are more likely to seek treatment during a period of depression.
After you are diagnosed with bipolar disorder, you'll need to keep a long-term relationship with your doctor or therapist. It can help you make sure that your treatment is consistent and that your medicines can be adjusted as needed.
Although your family doctor or general practitioner can diagnose bipolar disorder, you may be referred to a psychiatrist or mental health clinic that specializes in treating such disorders. The psychiatrist or mental health clinic can prescribe medicines and provide counselling.
Counselling can help you deal with mood changes and the impact bipolar disorder can have on your work and family relationships. In addition to psychiatrists, you may be referred to other health professionals who can provide counselling, including:
Examinations and Tests
To find out if you have bipolar disorder, your doctor will ask detailed questions about your symptoms. You will be asked how long your symptoms last and how often you have them. Your doctor will ask about your family history and may do a mental health assessment.
Blood and urine tests, such as a test of your thyroid, may be done to make sure another problem isn't causing your symptoms. A toxicology screen looks at blood, urine, or hair for the presence of drugs.
The earlier the disease is confirmed, the sooner you can get treatment, feel better, and improve the quality of your life. This can also reduce your risk of other health problems, such as alcohol and drug abuse.
Bipolar disorder is treated with a combination of medicines and counselling. It's important to take your medicines exactly as prescribed, even when you feel well. Your doctor may have you try different combinations of medicines to find what's right for you.
Your family doctor or general practitioner can prescribe medicines to treat bipolar disorder. But you will probably be referred to a psychiatrist, who is trained specifically to treat mental disorders.
Many people don't get help for bipolar disorder. You may not seek treatment because you think the symptoms aren't bad enough or that you can work things out on your own. But treatment can help you manage the highs and lows.
If you need help deciding whether to see your doctor, see some reasons why people don't get help and how to overcome them.
Your treatment plan
Treatment often starts with helping you through an "acute" phase or manic episode. You may be suicidal or psychotic or using such poor judgment that you are in danger of harming yourself. Your doctor may decide that you should be hospitalized for your own safety, especially if he or she thinks you are suicidal.
Medicines that may be used include mood stabilizers and antipsychotics. Over time, these medicines will be adjusted with the goal of preventing manic and depressive episodes. It may take months for your symptoms to go away and for you to be able to maintain a normal routine of work and activity. To learn more, see Medications.
Counselling is also an important part of treatment. It can help you cope with problems that may come up in your work or relationships because of bipolar disorder. To learn more, see Other Treatment.
You can also do some things on your own to help manage your symptoms and maintain a normal routine. Joining a support group to talk with others who have bipolar disorder can help. To learn more, see Home Treatment.
Bipolar disorder cannot be prevented. But often the mood swings can be controlled with medicines. And there are many things you can do for yourself to help manage highs and lows. To learn more, see Home Treatment.
Home treatment is important in bipolar disorder. There are many things you can do to help control mood swings. You don't have to do them all at once. Try to do one thing, such as eating a healthy diet, then add another when you can.
Watch what you eat
Try to eat a healthy, balanced diet. A balanced diet includes foods from different food groups, such as whole grains, dairy, fruits and vegetables, and protein. Eat a variety of foods from each group. (For example, eat different fruits from the fruit group instead of only apples.) A varied diet helps you get all the nutrients you need. No single food provides every nutrient.
Keep good habits
- Take your medicine every day as prescribed.
- Get enough exercise. Try moderate to vigorous activity for at least 2½ hours a week, if possible. A brisk walk is an example of moderate activity.
- Avoid alcohol and illegal drugs.
- Limit caffeine and nicotine.
Reduce stress, get rest
- Try to control the amount of stress in your life. Techniques to relieve stress include physical activity and exercise, breathing exercises, muscle relaxation, and counselling and support groups.
- Get enough sleep. Keep your room dark and quiet, and try to go to bed at the same time every night. If you plan to travel into other time zones, ask your doctor if you should make any changes in your medicines. And ask what to do if you have a manic or depressive episode while you are away.
Ask for help
- Learn to recognize the early warning signs of your manic and depressive episodes.
- Ask for help from friends and family when needed. You may need help with daily activities if you are depressed. Or you may need support to control high energy levels if you have a manic high.
How family and friends can help
Family members often feel helpless when a loved one is depressed or manic. But you can help.
- Encourage the person to take prescribed medicines regularly, even when he or she is feeling good.
- If family therapy is available, it is important for everyone in the family to attend the sessions.
- Recognize a lapse into a manic or depressive episode. Help the person cope and get treatment.
- Allow your loved one to take enough time to feel better and get back into daily activities.
- Learn the difference between hypomania and when your loved one is just having a good day. Hypomania is an elevated or irritable mood that is clearly different from a regular non-depressed mood. It can last for a week or more.
Know the signs
- Learn the warning signs of suicide. They include:
- Drinking alcohol heavily or taking illegal drugs.
- Talking, writing, or drawing about death, such as writing suicide notes.
- Talking about things that can cause harm, such as pills, guns, or knives.
- Spending long periods of time alone.
- Giving away possessions.
- Acting aggressive or suddenly appearing calm.
Get help for you
If a loved one has bipolar disorder, it may be helpful for you to get counselling to deal with its impact on your own life. Manic episodes can be particularly hard. Talk with a psychiatrist, a psychologist, a social worker, or a mental health counsellor for your own therapy.
Counselling can also be helpful for a child who has a bipolar parent. The parent's mood swings may negatively affect the child. This can cause tearfulness, anger, depression, or rebellious behaviour.

Medicines, when taken as prescribed, can help control bipolar mood swings. Your doctor will vary the amounts and combinations of your medicines according to your symptoms, which type of bipolar disorder you have, and how you respond to the medicines.
Taking medicines during pregnancy for bipolar disorder may increase the risk of birth defects. If you are pregnant or thinking of becoming pregnant, talk to your doctor. You may need to keep taking medicine if your bipolar disorder is severe. Your doctor can help weigh the risks of treatment against the risk of harm to your pregnancy.
Several medicines are used to treat bipolar disorder. It may take time to find the treatment that works best for you. The most common medicines used are:
- Mood stabilizers, such as lithium (Carbolith, Lithane). Experts believe that lithium may affect certain brain chemicals (neurotransmitters) that cause mood changes. A mood stabilizer and an antipsychotic are recommended as the first medicines for acute manic episodes.
- Anticonvulsants, such as carbamazepine (such as Tegretol), divalproex (Epival), and valproate (Depakene). They are also considered mood stabilizers. Divalproex and valproate are used to treat manic episodes. The anticonvulsant lamotrigine (Lamictal) may be helpful for bipolar depression.
- Antipsychotics, such as aripiprazole (Abilify), olanzapine (Zyprexa), quetiapine (Seroquel), risperidone (Risperdal), and ziprasidone (Zeldox). Antipsychotics improve manic episodes. Olanzapine may be used in combination with other medicines.
- Benzodiazepines, such as diazepam (Valium). These may be used instead of antipsychotics or as an additional medicine during a manic phase.
Medicines and your lifestyle
When you and your doctor are discussing your medicines, think about whether your lifestyle allows you to take medicines on time every day. A medicine you only take once a day may work best for you if you have a hard time remembering to take your medicines.
During your doctor's appointment, ask about:
- The side effects of each medicine.
- How often you will need to take the medicines.
- How the medicines may interact with other medicines you are taking.
- Whether it's important to take the medicines at the same time every day.
You'll need to check in with your doctor regularly when taking medicines for bipolar disorder.
If you are prescribed carbamazepine, lithium, or valproate, you will need regular blood tests to monitor the amount of medicine in your blood. Too much lithium in your bloodstream may lead to serious side effects. Blood tests can also help show how medicines are affecting your liver, kidneys, and thyroid gland or to measure the number of blood cells in your body.
The use of antidepressants alone has been linked to an increase in manic episodes. Antidepressant treatment needs to be monitored closely to avoid causing a manic episode.
Health Canada and the U.S. Food and Drug Administration (FDA) have issued advisories on antidepressant medicines and the risk of suicide. It is not recommended that people stop using these medicines. Instead, a person taking antidepressants should be watched for warning signs of suicide. This is especially important at the beginning of treatment or when doses are changed.
The FDA has also issued a warning on anticonvulsants and the risk of suicide and suicidal thoughts. The FDA does not recommend that people stop using these medicines. Instead, people who take anticonvulsant medicine should be watched closely for warning signs of suicide. People who take anticonvulsant medicine and who are worried about this side effect should talk to a doctor.
Almost all people who have bipolar disorder need medicine. But counselling is also important to help you cope with work and relationship struggles related to your illness.
- Cognitive-behavioural therapy is a type of counselling aimed at teaching you how to become healthier by modifying certain thought and behaviour patterns. It is based on the theory that thought and behaviour can affect a person's symptoms and can slow or prevent recovery.
- Interpersonal therapy focuses on social and personal relationships and related problems. You and your counsellor discuss grief and loss, role disputes in relationships, and relationship transitions.
- Problem solving is a brief, focused form of cognitive therapy used to treat depression. It focuses on specific problems and how you can solve them.
- Family therapy is a type of counselling used to help families deal with a stressful situation or a life-changing event. In family therapy, each person can express any concerns and fears about how the problem affects the person who has bipolar disorder and the family as a whole.
No matter which type of counselling you choose, establish a long-term relationship with a counsellor you like. The counsellor will help you recognize personality changes that show when you are moving into a mood swing. Getting early treatment can reduce the length of the high or low. See some tips for finding a counsellor or therapist.
In some cases, electroconvulsive therapy (ECT) may be an option. In this procedure, brief electrical stimulation to the brain is given through electrodes placed on the head. The stimulation produces a short seizure that is thought to balance brain chemicals.
A few studies suggest that adding omega-3 fatty acids to medicine (such as lithium) can help reduce the depressive symptoms in some people. Omega-3 fatty acids don't seem to have any affect on the manic symptoms of bipolar disorder. And omega-3 fatty acids alone are not a good treatment for bipolar disease. They are not a replacement for medicine or other therapy used to treat bipolar disorder.footnote 7, footnote 8
