Bipolar disorder (formerly called manic-depressive illness or manic depression) is a mental disorder that causes unusual shifts in mood, energy, activity levels, concentration, and the ability to carry out day-to-day tasks.
There are three types of bipolar disorder. All three types involve clear changes in mood, energy, and activity levels. These moods range from periods of extremely “up,” elated, irritable, or energized behavior (known as manic episodes) to very “down,” sad, indifferent, or hopeless periods (known as depressive episodes). Less severe manic periods are known as hypomanic episodes.
- Bipolar I Disorder— defined by manic episodes that last at least 7 days, or by manic symptoms that are so severe that the person needs immediate hospital care. Usually, depressive episodes occur as well, typically lasting at least 2 weeks. Episodes of depression with mixed features (having depressive symptoms and manic symptoms at the same time) are also possible.
- Bipolar II Disorder— defined by a pattern of depressive episodes and hypomanic episodes, but not the full-blown manic episodes that are typical of Bipolar I Disorder.
- Cyclothymic Disorder (also called Cyclothymia)— defined by periods of hypomanic symptoms as well as periods of depressive symptoms lasting for at least 2 years (1 year in children and adolescents). However, the symptoms do not meet the diagnostic requirements for a hypomanic episode and a depressive episode.
Sometimes a person might experience symptoms of bipolar disorder that do not match the three categories listed above, which is referred to as “other specified and unspecified bipolar and related disorders.”
Bipolar disorder is typically diagnosed during late adolescence (teen years) or early adulthood. Occasionally, bipolar symptoms can appear in children. Bipolar disorder can also first appear during a woman’s pregnancy or following childbirth. Although the symptoms may vary over time, bipolar disorder usually requires lifelong treatment. Following a prescribed treatment plan can help people manage their symptoms and improve their quality of life.
Signs and Symptoms
People with bipolar disorder experience periods of unusually intense emotion, changes in sleep patterns and activity levels, and uncharacteristic behaviors—often without recognizing their likely harmful or undesirable effects. These distinct periods are called “mood episodes.” Mood episodes are very different from the moods and behaviors that are typical for the person. During an episode, the symptoms last every day for most of the day. Episodes may also last for longer periods, such as several days or weeks.
People having a manic episode may:
People having a depressive episode may:
Feel very “up,” “high,” elated, or irritable or touchy
Feel very sad, “down,” empty, worried, or hopeless
Feel “jumpy” or “wired”
Feel slowed down or restless
Have a decreased need for sleep
Have trouble falling asleep, wake up too early, or sleep too much
Have a loss of appetite
Experience increased appetite and weight gain
Talk very fast about a lot of different things
Talk very slowly, feel like they have nothing to say, forget a lot
Feel like their thoughts are racing
Have trouble concentrating or making decisions
Think they can do a lot of things at once
Feel unable to do even simple things
Do risky things that show poor judgment, such as eat and drink excessively, spend or give away a lot of money, or have reckless sex
Have little interest in almost all activities, a decreased or absent sex drive, or an inability to experience pleasure (“anhedonia”)
Feel like they are unusually important, talented, or powerful
Feel hopeless or worthless, think about death or suicide
Sometimes people experience both manic and depressive symptoms in the same episode. This kind of episode is called an episode with mixed features. People experiencing an episode with mixed features may feel very sad, empty, or hopeless, while, at the same, time feeling extremely energized.
A person may have bipolar disorder even if their symptoms are less extreme. For example, some people with bipolar disorder (Bipolar II) experience hypomania, a less severe form of mania. During a hypomanic episode, a person may feel very good, be able to get things done, and keep up with day-to-day life. The person may not feel that anything is wrong, but family and friends may recognize the changes in mood or activity levels as possible bipolar disorder. Without proper treatment, people with hypomania can develop severe mania or depression.
Proper diagnosis and treatment can help people with bipolar disorder lead healthy and active lives. Talking with a doctor or other licensed health care provider is the first step. The health care provider can complete a physical exam and order necessary medical tests to rule out other conditions. The health care provider may then conduct a mental health evaluation or provide a referral to a trained mental health care provider, such as a psychiatrist, psychologist, or clinical social worker who has experience in diagnosing and treating bipolar disorder.
Mental health care providers usually diagnose bipolar disorder based on a person’s symptoms, lifetime history, experiences, and, in some cases, family history. Accurate diagnosis in youth is particularly important. You can find tips for talking with your health care provider in the NIMH fact sheet on Taking Control of Your Mental Health: Tips for Talking with Your Health Care Provider.
Note for Health Care Providers: People with bipolar disorder are more likely to seek help when they are depressed than when they are experiencing mania or hypomania. Taking a careful medical history is essential to ensure that bipolar disorder is not mistaken for major depression. This is especially important when treating an initial episode of depression as antidepressant medications can trigger a manic episode in people who have an increased chance of having bipolar disorder.
Bipolar Disorder and Other Conditions
Some bipolar disorder symptoms are similar to those of other illnesses, which can make it challenging for a health care provider to make a diagnosis. In addition, many people may have bipolar disorder along with another mental disorder or condition, such as an anxiety disorder, substance use disorder, or an eating disorder. People with bipolar disorder have an increased chance of having thyroid disease, migraine headaches, heart disease, diabetes, obesity, and other physical illnesses.
Psychosis: Sometimes, a person with severe episodes of mania or depression may experience psychotic symptoms, such as hallucinations or delusions. The psychotic symptoms tend to match the person’s extreme mood. For example:
- People having psychotic symptoms during a manic episode may have the unrealistic belief that they are famous, have a lot of money, or have special powers.
- People having psychotic symptoms during a depressive episode may falsely believe they are financially ruined and penniless, have committed a crime, or have an unrecognized serious illness.
As a result, people with bipolar disorder who also have psychotic symptoms are sometimes incorrectly diagnosed with schizophrenia. When people have symptoms of bipolar disorder and also experience periods of psychosis that are separate from mood episodes, the appropriate diagnosis may be schizoaffective disorder.
Anxiety: It is common for people with bipolar disorder to also have an anxiety disorder.
Attention-Deficit Hyperactivity Disorder (ADHD): It is common for people with bipolar disorder to also have ADHD.
Misuse of Drugs or Alcohol: People with bipolar disorder may misuse alcohol or drugs and engage in other high-risk behaviors at times of impaired judgment during manic episodes. Although the negative effects of alcohol use or drug use may be most evident to family, friends, and health care providers, it is important to recognize the presence of an associated mental disorder.
Eating Disorders: In some cases, people with bipolar disorder also have an eating disorder, such as binge eating or bulimia.
Researchers are studying the possible causes of bipolar disorder. Most agree that there is no single cause and it is likely that many factors contribute to a person’s chance of having the illness.
Brain Structure and Functioning: Some studies indicate that the brains of people with bipolar disorder may differ from the brains of people who do not have bipolar disorder or any other mental disorder. Learning more about these differences may help scientists understand bipolar disorder and determine which treatments will work best. At this time, health care providers base the diagnosis and treatment plan on a person’s symptoms and history, rather than brain imaging or other diagnostic tests.
Genetics: Some research suggests that people with certain genes are more likely to develop bipolar disorder. Research also shows that people who have a parent or sibling with bipolar disorder have an increased chance of having the disorder themselves. Many genes are involved, and no one gene can cause the disorder. Learning more about how genes play a role in bipolar disorder may help researchers develop new treatments.
Treatments and Therapies
Treatment can help many people, including those with the most severe forms of bipolar disorder. An effective treatment plan usually includes a combination of medication and psychotherapy, also called “talk therapy.”
Bipolar disorder is a lifelong illness. Episodes of mania and depression typically come back over time. Between episodes, many people with bipolar disorder are free of mood changes, but some people may have lingering symptoms. Long-term, continuous treatment can help people manage these symptoms.
Certain medications can help manage symptoms of bipolar disorder. Some people may need to try several different medications and work with their health care provider before finding medications that work best.
Medications generally used to treat bipolar disorder include mood stabilizers and second-generation (“atypical”) antipsychotics. Treatment plans may also include medications that target sleep or anxiety. Health care providers often prescribe antidepressant medication to treat depressive episodes in bipolar disorder, combining the antidepressant with a mood stabilizer to prevent triggering a manic episode.
People taking medication should:
- Talk with their health care provider to understand the risks and benefits of the medication.
- Tell their health care provider about any prescription drugs, over-the-counter medications, or supplements they are already taking.
- Report any concerns about side effects to a health care provider right away. The health care provider may need to change the dose or try a different medication.
- Remember that medication for bipolar disorder must be taken consistently, as prescribed, even when one is feeling well.
Avoid stopping a medication without talking to a health care provider first. Suddenly stopping a medication may lead to a “rebound” or worsening of bipolar disorder symptoms. For basic information about medications, visit NIMH’s Mental Health Medications webpage. For the most up-to-date information on medications, side effects, and warnings, visit the U.S. Food and Drug Administration (FDA) Medication Guides website.
Psychotherapy, also called “talk therapy,” can be an effective part of the treatment plan for people with bipolar disorder. Psychotherapy is a term for a variety of treatment techniques that aim to help a person identify and change troubling emotions, thoughts, and behaviors. It can provide support, education, and guidance to people with bipolar disorder and their families. Treatment may include therapies such as cognitive-behavioral therapy (CBT) and psychoeducation, which are used to treat a variety of conditions.
Treatment may also include newer therapies designed specifically for the treatment of bipolar disorder, including interpersonal and social rhythm therapy (IPSRT) and family-focused therapy. Determining whether intensive psychotherapeutic intervention at the earliest stages of bipolar disorder can prevent or limit its full-blown onset is an important area of ongoing research.

Other Treatment Options
Some people may find other treatments helpful in managing their bipolar symptoms, including:
Electroconvulsive Therapy (ECT): ECT is a brain stimulation procedure that can help people get relief from severe symptoms of bipolar disorder. With modern ECT, a person usually goes through a series of treatment sessions over several weeks. ECT is delivered under general anesthesia and is safe. It can be effective in treating severe depressive and manic episodes, which occur most often when medication and psychotherapy are not effective or are not safe for a particular patient. ECT can also be effective when a rapid response is needed, as in the case of suicide risk or catatonia (a state of unresponsiveness).
More research is needed to determine the effects of other treatments, including:
Transcranial magnetic stimulation (TMS): TMS is a newer approach to brain stimulation that uses magnetic waves. It is delivered to an awake patient most days for 1 month. Research shows that TMS is helpful for many people with various subtypes of depression, but its role in the treatment of bipolar disorder is still under study.
Supplements: Although there are reports that some supplements and herbs may help, not enough research has been conducted to fully understand how these supplements may affect people with bipolar disorder.
It is important for a health care provider to know about all prescription drugs, over-the-counter medications, and supplements a patient is taking. Certain medications and supplements taken together may cause unwanted or dangerous effects.
Beyond Treatment: Things You Can Do
Regular Exercise: Regular aerobic exercise, such as jogging, brisk walking, swimming, or bicycling, helps with depression and anxiety, promotes better sleep, and is healthy for your heart and brain. There is also some evidence that anaerobic exercise such as weightlifting, yoga, and Pilates can be helpful. Check with your health care provider before you start a new exercise regimen.
Keeping a Life Chart: Even with proper treatment, mood changes can occur. Treatment is more effective when a patient and health care provider work together and talk openly about concerns and choices. Keeping a life chart that records daily mood symptoms, treatments, sleep patterns, and life events can help patients and health care providers track and treat bipolar disorder over time. Patients can easily share data collected via smartphone apps – including self-reports, self- ratings, and activity data – with their health care providers and therapists.

Remember: Bipolar disorder is a lifelong illness, but long-term, ongoing treatment can help control symptoms and enable you to live a healthy life.
Join a Study
Clinical trials are research studies that look at new ways to prevent, detect, or treat diseases and conditions. The goal of clinical trials is to determine if a new test or treatment works and is safe. Although individuals may benefit from being part of a clinical trial, participants should be aware that the primary purpose of a clinical trial is to gain new scientific knowledge so that others may be better helped in the future.
Researchers at NIMH and around the country conduct many studies with patients and healthy volunteers. We have new and better treatment options today because of what clinical trials uncovered years ago. Be part of tomorrow’s medical breakthroughs. Talk to your health care provider about clinical trials, their benefits and risks, and whether one is right for you.
