Bipolar disorder, also known as manic-depressive illness, is a lifelong condition that can affect both how you feel and how you act. It is a mood disorder thought to be caused by chemical imbalances in the brain that can result in extreme swings in mood—from manic highs to depressive lows. Symptoms of bipolar disorder are severe. They are different from the normal ups and downs that everyone goes through from time to time. Bipolar disorder symptoms can result in damaged relationships, poor job or school performance, and even suicide. But bipolar disorder can be treated, and people with this illness can lead full and productive lives.

Bipolar disorder often develops in a person’s late teens or early adult years. At least half of all cases start before age 25. Some people have their first symptoms during childhood, while others may develop symptoms late in life.

Bipolar disorder is not easy to spot when it starts. The symptoms may seem like separate problems, not recognized as parts of a larger problem. Some people suffer for years before they are properly diagnosed and treated. Like diabetes or heart disease, bipolar disorder is a long-term illness that must be carefully managed throughout a person’s life.

What are the symptoms of bipolar disorder? — People with bipolar disorder experience unusually intense emotional states that occur in distinct periods called “mood episodes.” An overly joyful or overexcited state is called a manic episode, and an extremely sad or hopeless state is called a depressive episode. Sometimes, a mood episode includes symptoms of both mania and depression. This is called a mixed state. People with bipolar disorder also may be explosive and irritable during a mood episode.

Extreme changes in energy, activity, sleep, and behavior go along with these changes in mood. It is possible for someone with bipolar disorder to experience a long-lasting period of unstable moods rather than discrete episodes of depression or mania.

Symptoms of bipolar disorder are described below.

In addition to mania and depression, bipolar disorder can cause a range of moods, as shown on the scale.

One side of the scale includes severe depression, moderate depression, and mild low mood. Moderate depression may cause less extreme symptoms, and mild low mood is called dysthymia when it is chronic or long-term. In the middle of the scale is normal or balanced mood.

At the other end of the scale are hypomania and severe mania. Some people with bipolar disorder experience hypomania. During hypomanic episodes, a person may have increased energy and activity levels that are not as severe as typical mania, or he or she may have episodes that last less than a week and do not require emergency care. A person having a hypomanic episode may feel very good, be highly productive, and function well. This person may not feel that anything is wrong even as family and friends recognize the mood swings as possible bipolar disorder. Without proper treatment, however, people with hypomania may develop severe mania or depression.

During a mixed state, symptoms often include agitation, trouble sleeping, major changes in appetite, and suicidal thinking. People in a mixed state may feel very sad or hopeless while feeling extremely energized.

Sometimes, a person with severe episodes of mania or depression has psychotic symptoms too, such as hallucinations or delusions. The psychotic symptoms tend to reflect the person’s extreme mood. For example, psychotic symptoms for a person having a manic episode may include believing he or she is famous, has a lot of money, or has special powers. In the same way, a person having a depressive episode may believe he or she is ruined and penniless, or has committed a crime. As a result, people with bipolar disorder who have psychotic symptoms are sometimes wrongly diagnosed as having schizophrenia, another severe mental illness that is linked with hallucinations and delusions.

People with bipolar disorder may also have behavioral problems. They may abuse alcohol or substances, have relationship problems, or perform poorly in school or at work. At first, it’s not easy to recognize these problems as signs of a major mental illness.

Bipolar Depression — Although people may recognize the term “bipolar disorder,” you may be a little less familiar with the term “bipolar depression.” Bipolar depression refers to the depressive moods or lows of bipolar disorder. While symptoms of both bipolar depression and bipolar mania can cause problems for people with bipolar disorder, some people report that bipolar depression tends to have a greater impact. In general, episodes of bipolar depression last longer than episodes of bipolar mania, and when they are ill, people with bipolar disorder experience depressive symptoms at least three times as often as they do manic symptoms. In addition, recovering from depressive episodes typically takes longer than it does for manic episodes.

In order to get a proper diagnosis and appropriate treatment, be sure to talk to your doctor or therapist about all the symptoms you are experiencing, including any manic episodes. The good news is that there are treatment options available that may help. To prepare for your next appointment, here are some questions to ask ..

How does bipolar disorder affect someone over time? — Bipolar disorder usually lasts a lifetime. Episodes of mania and depression typically come back over time. Between episodes, many people with bipolar disorder are free of symptoms, but some people may have lingering symptoms.

Doctors usually diagnose mental disorders using guidelines from the Diagnostic and Statistical Manual of Mental Disorders, or DSM. According to the DSM, there are four basic types of bipolar disorder:

1. Bipolar I Disorder is mainly defined by manic or mixed episodes that last at least seven days, or by manic symptoms that are so severe that the person needs immediate hospital care. Usually, the person also has depressive episodes, typically lasting at least two weeks. The symptoms of mania or depression must be a major change from the person’s normal behavior.
2. Bipolar II Disorder is defined by a pattern of depressive episodes shifting back and forth with hypomanic episodes, but no full-blown manic or mixed episodes.
3. Bipolar Disorder Not Otherwise Specified (BP-NOS) is diagnosed when a person has symptoms of the illness that do not meet diagnostic criteria for either bipolar I or II. The symptoms may not last long enough, or the person may have too few symptoms, to be diagnosed with bipolar I or II. However, the symptoms are clearly out of the person’s normal range of behavior.
4. Cyclothymic Disorder, or Cyclothymia, is a mild form of bipolar disorder. People who have cyclothymia have episodes of hypomania that shift back and forth with mild depression for at least two years. However, the symptoms do not meet the diagnostic requirements for any other type of bipolar disorder.

Some people may be diagnosed with rapid-cycling bipolar disorder. This is when a person has four or more episodes of major depression, mania, hypomania, or mixed symptoms within a year. Some people experience more than one episode in a week, or even within one day. Rapid cycling seems to be more common in people who have severe bipolar disorder and may be more common in people who have their first episode at a younger age. One study found that people with rapid cycling had their first episode about four years earlier, during mid to late teen years, than people without rapid cycling bipolar disorder. Rapid cycling affects more women than men.

Bipolar disorder tends to worsen if it is not treated. Over time, a person may suffer more frequent and more severe episodes than when the illness first appeared. Also, delays in getting the correct diagnosis and treatment make a person more likely to experience personal, social, and work-related problems.

Proper diagnosis and treatment helps people with bipolar disorder lead healthy and productive lives. In most cases, treatment can help reduce the frequency and severity of episodes.

How is bipolar disorder treated? — To date, there is no cure for bipolar disorder. But proper treatment helps most people with bipolar disorder gain better control of their mood swings and related symptoms. This is also true for people with the most severe forms of the illness. Because bipolar disorder is a lifelong and recurrent illness, people with the disorder need long-term treatment to maintain control of bipolar symptoms. An effective maintenance treatment plan includes medication and psychotherapy for preventing relapse and reducing symptom severity.

Medications to treat Bipolar Disorder — Bipolar disorder can be diagnosed and medications prescribed by people with an M.D. (doctor of medicine). Usually, bipolar medications are prescribed by a psychiatrist or psychiatric nurse practitioner or physician’s assistant trained in psychiatry.  Not everyone responds to medications in the same way. Several different medications may need to be tried before the best course of treatment is found.

Keeping a chart of daily mood symptoms, treatments, sleep patterns, and life events can help the doctor track and treat the illness most effectively. Sometimes this is called a daily life chart. If a person’s symptoms change or if side effects become serious, the doctor may switch or add medications.  Here is a resource for a mood chart:  http://www.healthyplace.com/mood-journal/

Some of the types of medications generally used to treat bipolar disorder are listed on the next page. Information on medications can change. For the most up to date information on use and side effects contact the U.S. Food and Drug Administration (FDA)

1. Mood stabilizing medications are usually the first choice to treat bipolar disorder. In general, people with bipolar disorder continue treatment with mood stabilizers for years. Except for lithium, many of these medications are anticonvulsants. Anticonvulsant medications are usually used to treat seizures, but they also help control moods. These medications are commonly used as mood stabilizers in bipolar disorder:

• Lithium (sometimes known as Eskalith or Lithobid) was the first mood-stabilizing medication approved by the U.S. Food and Drug Administration (FDA) in the 1970s for treatment of mania. It is often very effective in controlling symptoms of mania and preventing the recurrence of manic and depressive episodes.
• Valproic acid or divalproex sodium (Depakote), approved by the FDA in 1995 for treating mania, is a popular alternative to lithium for bipolar disorder. It is generally as effective as lithium for treating bipolar disorder.  Also see the section in this booklet, “Should young women take valproic acid?”
• More recently, the anticonvulsant lamotrigine (Lamictal) received FDA approval for maintenance treatment of bipolar disorder.
• Other anticonvulsant medications, including gabapentin (Neurontin), topiramate (Topamax), and oxcarbazepine (Trileptal) are sometimes prescribed. No large studies have shown that these medications are more effective than mood stabilizers.

Lithium and Thyroid Function — People with bipolar disorder often have thyroid gland problems. Lithium treatment may also cause low thyroid levels in some people. Low thyroid function, called hypothyroidism, has been associated with rapid cycling in some people with bipolar disorder, especially women. Because too much or too little thyroid hormone can lead to mood and energy changes, it is important to have a doctor check thyroid levels carefully. A person with bipolar disorder may need to take thyroid medication, in addition to medications for bipolar disorder, to keep thyroid levels balanced.

2. Atypical antipsychotic medications are sometimes used to treat symptoms of bipolar disorder. Often, these medications are taken with other medications. Atypical antipsychotic medications are called “atypical” to set them apart from earlier medications, which are called “conventional” or “first-generation” antipsychotics.

• Olanzapine (Zyprexa), when given with an antidepressant medication, may help relieve symptoms of severe mania or psychosis. Olanzapine is also available in an injectable form, which quickly treats agitation associated with a manic or mixed episode. Olanzapine can be used for maintenance treatment of bipolar disorder as well, even when a person does not have psychotic symptoms. However, some studies show that people taking olanzapine may gain weight and have other side effects that can increase their risk for diabetes and heart disease. These side effects are more likely in people taking olanzapine when compared with people prescribed other atypical antipsychotics.
• Aripiprazole (Abilify), like olanzapine, is approved for treatment of a manic or mixed episode. Aripiprazole is also used for maintenance treatment after a severe or sudden episode. As with olanzapine, aripiprazole also can be injected for urgent treatment of symptoms of manic or mixed episodes of bipolar disorder.
• Quetiapine (Seroquel) relieves the symptoms of severe and sudden manic episodes. In that way, quetiapine is like almost all antipsychotics. In 2006, it became the first atypical antipsychotic to also receive FDA approval for the treatment of bipolar depressive episodes.
• Risperidone (Risperdal) and ziprasidone (Geodon) are other atypical antipsychotics that may also be prescribed for controlling manic or mixed episodes.

3. Antidepressant medications are sometimes used to treat symptoms of depression in bipolar disorder. People with bipolar disorder who take antidepressants often take a mood stabilizer too. Doctors usually require this because taking only an antidepressant can increase a person’s risk of switching to mania or hypomania, or of developing rapid cycling symptoms.To prevent this switch, doctors who prescribe antidepressants for treating bipolar disorder also usually require the person to take a mood-stabilizing medication at the same time.

Recently, a large-scale, NIMH-funded study showed that for many people, adding an antidepressant to a mood stabilizer is no more effective in treating the depression than using only a mood stabilizer.

• Fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft), and bupropion (Wellbutrin) are examples of antidepressants that may be prescribed to treat symptoms of bipolar depression.

Some medications are better at treating one type of bipolar symptoms than another. For example, lamotrigine (Lamictal) seems to be helpful in controlling depressive symptoms of bipolar disorder.

4. Sleep Medications — People with bipolar disorder who have trouble sleeping usually sleep better after getting treatment for bipolar disorder. However, if sleeplessness does not improve, the doctor may suggest a change in medications. If the problems still continue, the doctor may prescribe sedatives or other sleep medications.

People with bipolar disorder should tell their doctor about all prescription drugs, over-the-counter medications, or supplements they are taking. Certain medications and supplements taken together may cause unwanted or dangerous effects.

Herbal Supplements — In general, there is not much research about herbal or natural supplements. Little is known about their effects on bipolar disorder. An herb called St. John’s wort (Hypericum perforatum), often marketed as a natural antidepressant, may cause a switch to mania in some people with bipolar disorder. St. John’s wort can also make other medications less effective, including some antidepressant and anticonvulsant medications. Scientists are also researching omega-3 fatty acids (most commonly found in fish oil) to measure their usefulness for long-term treatment of bipolar disorder.⁴⁷ Study results have been mixed.It is important to talk with a doctor before taking any herbal or natural supplements because of the serious risk of interactions with other medications.

Psychotherapy to treat Bipolar Disorder — In addition to medication, psychotherapy, or “talk” therapy, can be an effective treatment for bipolar disorder. It can provide support, education, and guidance to people with bipolar disorder and their families. Some psychotherapy treatments used to treat bipolar disorder include:

1. Cognitive behavioral therapy (CBT) helps people with bipolar disorder learn to change harmful or negative thought patterns and behaviors.
2. Family-focused therapy includes family members. It helps enhance family coping strategies, such as recognizing new episodes early and helping their loved one. This therapy also improves communication and problem-solving.
3. Interpersonal and social rhythm therapy helps people with bipolar disorder improve their relationships with others and manage their daily routines. Regular daily routines and sleep schedules may help protect against manic episodes.
4. Psychoeducation teaches people with bipolar disorder about the illness and its treatment. This treatment helps people recognize signs of relapse so they can seek treatment early, before a full-blown episode occurs. Usually done in a group, psychoeducation may also be helpful for family members and caregivers.

A licensed psychologist, social worker, or counselor typically provides these therapies. This mental health professional often works with the psychiatrist to track progress. The number, frequency, and type of sessions should be based on the treatment needs of each person. As with medication, following the doctor’s instructions for any psychotherapy will provide the greatest benefit.

Recently, NIMH funded a clinical trial called the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). This was the largest treatment study ever conducted for bipolar disorder. In a study on psychotherapies, STEP-BD researchers compared people in two groups. The first group was treated with collaborative care (three sessions of psychoeducation over six weeks). The second group was treated with medication and intensive psychotherapy (30 sessions over nine months of CBT, interpersonal and social rhythm therapy, or family-focused therapy). Researchers found that the second group had fewer relapses, lower hospitalization rates, and were better able to stick with their treatment plans. They were also more likely to get well faster and stay well longer.

NIMH is supporting more research on which combinations of psychotherapy and medication work best. The goal is to help people with bipolar disorder live symptom-free for longer periods and to recover from episodes more quickly. Researchers also hope to determine whether psychotherapy helps delay the start of bipolar disorder in children at high risk for the illness.
