Until recently, bipolar disorder was known as manic depression. The word bipolar is now used to indicate the 2 poles, or extremes, that characterize the disorder. Bipolar disorder can affect a person's ability to experience a normal range of mood.

If you picture a globe, the North Pole would be mania, and the South Pole would be depression. Every time you experience symptoms at one pole for at least 1 week, it is called an episode. Experiencing 4 or more episodes of mania and/or depression in a year is called rapid-cycling bipolar disorder.

"Manic-depression distorts moods and thoughts, incites dreadful behaviors, destroys the basis of rational thought, and too often erodes the desire and will to live. It is an illness that is biological in its origins, yet one that feels psychological in the experience of it; an illness that is unique in conferring advantage and pleasure, yet one that brings in its wake almost unendurable suffering and, not infrequently, suicide."

"I am fortunate that I have not died from my illness, fortunate in having received the best medical care available, and fortunate in having the friends, colleagues, and family that I do."

Kay Redfield Jamison, Ph.D., An Unquiet Mind, 1995, p. 6. (Reprinted with permission from Alfred A. Knopf, a division of Random House, Inc.)

As defined by the American Psychiatric Association, bipolar disorder includes 4 main mood episodes—Mania, Hypomania, Depression, and Mixed Mood.

Types of Mood Episodes Associated With Bipolar Disorder1 :

• Manic Episode (Mania) is a distinct period during which there is an abnormally and constantly elevated, expansive, or irritable mood, lasting at least 1 week.
• Hypomanic Episode (Hypomania) is a milder form of mania that lasts at least 4 days.
• Major Depressive Episode (Depression) is a period during which there is either depressed mood or the loss of interest or pleasure in nearly all activities, lasting for at least 2 weeks.
• Mixed Episode is a period of time during which a person experiences both manic and major depressive symptoms nearly every day for at least 1 week.

Types of Bipolar Disorder:

• Bipolar I Disorder2
  One or more manic episodes or mixed episodes and often 1 or more major depressive episodes. Depressive episode may last for several weeks or months, alternating with intense symptoms of mania that may last just as long. Between episodes, there may be periods of normal functioning. Symptoms may also be related to seasonal changes.
• Bipolar II Disorder2
  One or more major depressive episodes accompanied by at least 1 hypomanic episode. Hypomanic episodes have symptoms similar to manic episodes but are less severe. Between episodes, there may be periods of normal functioning. Symptoms may also be related to seasonal changes.
• Cyclothymic Disorder2
  Chronic fluctuating mood disturbance involving periods of hypomanic symptoms and periods of depressive symptoms. It is a milder form of bipolar disorder; the periods of both depressive and hypomanic symptoms are shorter, less severe, and do not occur with regularity. Many, but not all, people with cyclothymic disorder may ultimately develop a more severe form of bipolar disorder.
• Bipolar Disorder Not Otherwise Specified
  When the bipolar disorder is not characterized by any of the above mentioned types of bipolar disorder.1 The experiences of bipolar disorder vary from person to person. Occasionally someone will experience the symptoms of a manic episode and a major depressive episode, but not fit into the above mentioned types of bipolar disorder. This is known as Bipolar Disorder Not Otherwise Specified. Just like the other types of bipolar disorder, Bipolar Disorder Not Otherwise Specified is a treatable disorder.

The Truth About Bipolar Disorder

When it comes to mental illness, most people fear what they do not understand. Many of the myths surrounding bipolar disorder, however, are being put to rest thanks to extensive research. Here are some myths that you may have heard:

Myth: People diagnosed with bipolar disorder spend their lives in mental institutions.
Truth: Bipolar disorder is a common illness that is experienced by millions of people, and the vast majority of people receive treatment outside of a hospital. Only in the event of an extreme manic episode or severe depressive episode are some people admitted to a hospital for their own safety. Mental institutions generally are reserved for patients who do not respond to treatment or for those whose illness is so severe that they are unable to take care of themselves. With the appropriate treatment, many people with bipolar disorder live normal lives.

Myth: People with bipolar disorder almost always commit suicide.
Truth: It is true that suicide is more common among people with bipolar disorder than many other psychiatric conditions, but not everyone with bipolar disorder commits suicide. Sometimes a person experiencing a manic or hypomanic episode stops taking their medication because they want to enjoy the high. Unfortunately, without proper medication they can potentially suffer another more severe episode, which can lead to suicidal impulses.

Myth: People with bipolar disorder seldom can hold down a job.
Truth: Bipolar disorder, like other mood disorders, does not entirely take away a person's ability to function. It does affect a person's moods in such a way that they may feel like they cannot do something even though they are able to.
There are many famous and prominent people who have bipolar disorder.

Bipolar disorder causes dramatic mood swings”from overly "high" and/or irritable to sad and hopeless, and then back again, often with periods of normal mood in between. Severe changes in energy and behavior go along with these changes in mood. The periods of highs and lows are called episodes of mania and depression.

Signs and symptoms of mania (or a manic episode) include:

• Increased energy, activity, and restlessness
• Excessively "high," overly good, euphoric mood
• Extreme irritability
• Racing thoughts and talking very fast, jumping from one idea to another
• Distractibility, can't concentrate well
• Little sleep needed
• Unrealistic beliefs in one's abilities and powers
• Poor judgment
• Spending sprees
• A lasting period of behavior that is different from usual
• Increased sexual drive
• Abuse of drugs, particularly cocaine, alcohol, and sleeping medications
• Provocative, intrusive, or aggressive behavior
• Denial that anything is wrong

A manic episode is diagnosed if elevated mood occurs with three or more of the other symptoms most of the day, nearly every day, for 1 week or longer. If the mood is irritable, four additional symptoms must be present.

Signs and symptoms of depression (or a depressive episode) include:

• Lasting sad, anxious, or empty mood
• Feelings of hopelessness or pessimism
• Feelings of guilt, worthlessness, or helplessness
• Loss of interest or pleasure in activities once enjoyed, including sex
• Decreased energy, a feeling of fatigue or of being "slowed down"
• Difficulty concentrating, remembering, making decisions
• Restlessness or irritability
• Sleeping too much, or can't sleep
• Change in appetite and/or unintended weight loss or gain
• Chronic pain or other persistent bodily symptoms that are not caused by physical illness or injury
• Thoughts of death or suicide, or suicide attempts

A depressive episode is diagnosed if five or more of these symptoms last most of the day, nearly every day, for a period of 2 weeks or longer.

A mild to moderate level of mania is called hypomania. Hypomania may feel good to the person who experiences it and may even be associated with good functioning and enhanced productivity. Thus even when family and friends learn to recognize the mood swings as possible bipolar disorder, the person may deny that anything is wrong. Without proper treatment, however, hypomania can become severe mania in some people or can switch into depression.

Sometimes, severe episodes of mania or depression include symptoms of psychosis (or psychotic symptoms). Common psychotic symptoms are hallucinations (hearing, seeing, or otherwise sensing the presence of things not actually there) and delusions (false, strongly held beliefs not influenced by logical reasoning or explained by a person's usual cultural concepts). Psychotic symptoms in bipolar disorder tend to reflect the extreme mood state at the time. For example, delusions of grandiosity, such as believing one is the President or has special powers or wealth, may occur during mania; delusions of guilt or worthlessness, such as believing that one is ruined and penniless or has committed some terrible crime, may appear during depression. People with bipolar disorder who have these symptoms are sometimes incorrectly diagnosed as having schizophrenia, another severe mental illness.

It may be helpful to think of the various mood states in bipolar disorder as a spectrum or continuous range. At one end is severe depression, above which is moderate depression and then mild low mood, which many people call "the blues" when it is short-lived but is termed "dysthymia" when it is chronic. Then there is normal or balanced mood, above which comes hypomania (mild to moderate mania), and then severe mania.

In some people, however, symptoms of mania and depression may occur together in what is called a mixed bipolar state. Symptoms of a mixed state often include agitation, trouble sleeping, significant change in appetite, psychosis, and suicidal thinking. A person may have a very sad, hopeless mood while at the same time feeling extremely energized.

Bipolar disorder may appear to be a problem other than mental illness—for instance, alcohol or drug abuse, poor school or work performance, or strained interpersonal relationships. Such problems in fact may be signs of an underlying mood disorder.

Diagnosis of Bipolar Disorder

Like other mental illnesses, bipolar disorder cannot yet be identified physiologically for example, through a blood test or a brain scan. Therefore, a diagnosis of bipolar disorder is made on the basis of symptoms, course of illness, and, when available, family history. The diagnostic criteria for bipolar disorder are described in the Diagnostic and Statistical Manual for Mental Disorders, fourth edition (DSM-IV).

Some people with bipolar disorder become suicidal. Anyone who is thinking about committing suicide needs immediate attention, preferably from a mental health professional or a physician. Anyone who talks about suicide should be taken seriously. Risk for suicide appears to be higher earlier in the course of the illness. Therefore, recognizing bipolar disorder early and learning how best to manage it may decrease the risk of death by suicide.

Signs and symptoms that may accompany suicidal feelings include:

• talking about feeling suicidal or wanting to die
• feeling hopeless, that nothing will ever change or get better
• feeling helpless, that nothing one does makes any difference
• feeling like a burden to family and friends
• abusing alcohol or drugs
• putting affairs in order (e.g., organizing finances or giving away possessions to prepare for one's death)
• writing a suicide note
• putting oneself in harm's way, or in situations where there is a danger of being killed

If you are feeling suicidal or know someone who is:

• call a doctor, emergency room, to get immediate help
• make sure you, or the suicidal person, are not left alone
• make sure that access is prevented to large amounts of medication, weapons, or other items that could be used for self-harm

While some suicide attempts are carefully planned over time, others are impulsive acts that have not been well thought out; thus, the final point in the box above may be a valuable long-term strategy for people with bipolar disorder. Either way, it is important to understand that suicidal feelings and actions are symptoms of an illness that can be treated. With proper treatment, suicidal feelings can be overcome.

Both children and adolescents can develop bipolar disorder. It is more likely to affect the children of parents who have the illness.

Unlike many adults with bipolar disorder, whose episodes tend to be more clearly defined, children and young adolescents with the illness often experience very fast mood swings between depression and mania many times within a day. Children with mania are more likely to be irritable and prone to destructive tantrums than to be overly happy and elated. Mixed symptoms also are common in youths with bipolar disorder. Older adolescents who develop the illness may have more classic, adult-type episodes and symptoms.

Bipolar disorder in children and adolescents can be hard to tell apart from other problems that may occur in these age groups. For example, while irritability and aggressiveness can indicate bipolar disorder, they also can be symptoms of attention deficit hyperactivity disorder, conduct disorder, oppositional defiant disorder, or other types of mental disorders more common among adults such as major depression or schizophrenia. Drug abuse also may lead to such symptoms.

For any illness, however, effective treatment depends on appropriate diagnosis. Children or adolescents with emotional and behavioral symptoms should be carefully evaluated by a mental health professional. Any child or adolescent who has suicidal feelings, talks about suicide, or attempts suicide should be taken seriously and should receive immediate help from a mental health specialist.

Scientists are learning about the possible causes of bipolar disorder through several kinds of studies. Most scientists now agree that there is no single cause for bipolar disorder—rather, many factors act together to produce the illness.

Because bipolar disorder tends to run in families, researchers have been searching for specific genes”the microscopic "building blocks" of DNA inside all cells that influence how the body and mind work and grow”passed down through generations that may increase a person's chance of developing the illness. But genes are not the whole story. Studies of identical twins, who share all the same genes, indicate that both genes and other factors play a role in bipolar disorder. If bipolar disorder were caused entirely by genes, then the identical twin of someone with the illness would always develop the illness, and research has shown that this is not the case. But if one twin has bipolar disorder, the other twin is more likely to develop the illness than is another sibling.

In addition, findings from gene research suggest that bipolar disorder, like other mental illnesses, does not occur because of a single gene. It appears likely that many different genes act together, and in combination with other factors of the person or the person's environment, to cause bipolar disorder. Finding these genes, each of which contributes only a small amount toward the vulnerability to bipolar disorder, has been extremely difficult. But scientists expect that the advanced research tools now being used will lead to these discoveries and to new and better treatments for bipolar disorder.

Brain-imaging studies are helping scientists learn what goes wrong in the brain to produce bipolar disorder and other mental illnesses.New brain-imaging techniques allow researchers to take pictures of the living brain at work, to examine its structure and activity, without the need for surgery or other invasive procedures. These techniques include magnetic resonance imaging (MRI), positron emission tomography (PET), and functional magnetic resonance imaging (fMRI). There is evidence from imaging studies that the brains of people with bipolar disorder may differ from the brains of healthy individuals. As the differences are more clearly identified and defined through research, scientists will gain a better understanding of the underlying causes of the illness, and eventually may be able to predict which types of treatment will work most effectively.

Because bipolar disorder is a recurrent illness, long-term preventive treatment is strongly recommended and almost always indicated. A strategy that combines medication and psychosocial treatment is optimal for managing the disorder over time.

In most cases, bipolar disorder is much better controlled if treatment is continuous than if it is on and off. But even when there are no breaks in treatment, mood changes can occur and should be reported immediately to your doctor. The doctor may be able to prevent a full-blown episode by making adjustments to the treatment plan. Working closely with the doctor and communicating openly about treatment concerns and options can make a difference in treatment effectiveness.

In addition, keeping a chart of daily mood symptoms, treatments, sleep patterns, and life events may help people with bipolar disorder and their families to better understand the illness. This chart also can help the doctor track and treat the illness most effectively.

Medications for bipolar disorder are prescribed by psychiatrists”medical doctors (M.D.) with expertise in the diagnosis and treatment of mental disorders. While primary care physicians who do not specialize in psychiatry also may prescribe these medications, it is recommended that people with bipolar disorder see a psychiatrist for treatment.

Medications known as "mood stabilizers" usually are prescribed to help control bipolar disorder. Several different types of mood stabilizers are available. In general, people with bipolar disorder continue treatment with mood stabilizers for extended periods of time (years). Other medications are added when necessary, typically for shorter periods, to treat episodes of mania or depression that break through despite the mood stabilizer.

• Lithium, the first mood-stabilizing medication approved by the U.S. Food and Drug Administration (FDA) for treatment of mania, is often very effective in controlling mania and preventing the recurrence of both manic and depressive episodes.
• Anticonvulsant medications, such as valproate (Depakote) or carbamazepine (Tegretol), also can have mood-stabilizing effects and may be especially useful for difficult-to-treat bipolar episodes. Valproate was FDA-approved in 1995 for treatment of mania.
• Newer anticonvulsant medications, including lamotrigine (Lamictal), gabapentin (Neurontin, and topiramate (Topamax), are being studied to determine how well they work in stabilizing mood cycles.
• Anticonvulsant medications may be combined with lithium, or with each other, for maximum effect.
• Children and adolescents with bipolar disorder generally are treated with lithium, but valproate and carbamazepine also are used. Researchers are evaluating the safety and efficacy of these and other psychotropic medications in children and adolescents. There is some evidence that valproate may lead to adverse hormone changes in teenage girls and polycystic ovary syndrome in women who began taking the medication before age 20. Therefore, young female patients taking valproate should be monitored carefully by a physician.
• Women with bipolar disorder who wish to conceive, or who become pregnant, face special challenges due to the possible harmful effects of existing mood stabilizing medications on the developing fetus and the nursing infant.Therefore, the benefits and risks of all available treatment options should be discussed with a clinician skilled in this area. New treatments with reduced risks during pregnancy and lactation are under study.

Treatment of Bipolar Depression

Research has shown that people with bipolar disorder are at risk of switching into mania or hypomania, or of developing rapid cycling, during treatment with antidepressant medication. Therefore, "mood-stabilizing" medications generally are required, alone or in combination with antidepressants, to protect people with bipolar disorder from this switch. Lithium and valproate are the most commonly used mood-stabilizing drugs today. However, research studies continue to evaluate the potential mood-stabilizing effects of newer medications.

• Atypical antipsychotic medications, including clozapine (Clozaril), olanzapine (Zyprexa), risperidone (Risperdal), quetiapine (Seroquel), and ziprasidone (Geodon), are being studied as possible treatments for bipolar disorder. Evidence suggests clozapine may be helpful as a mood stabilizer for people who do not respond to lithium or anticonvulsants. Other research has supported the efficacy of olanzapine for acute mania, an indication that has recently received FDA approval. Olanzapine may also help relieve psychotic depression.
• If insomnia is a problem, a high-potency benzodiazepine medication such as clonazepam (Klonopin) or lorazepam (Ativan) may be helpful to promote better sleep. However, since these medications may be habit-forming, they are best prescribed on a short-term basis. Other types of sedative medications, such as zolpidem (Ambien), are sometimes used instead.
• Changes to the treatment plan may be needed at various times during the course of bipolar disorder to manage the illness most effectively. A psychiatrist should guide any changes in type or dose of medication.
• Be sure to tell the psychiatrist about all other prescription drugs, over-the-counter medications, or natural supplements you may be taking. This is important because certain medications and supplements taken together may cause adverse reactions.
• To reduce the chance of relapse or of developing a new episode, it is important to stick to the treatment plan. Talk to your doctor if you have any concerns about the medications.

Thyroid Function

People with bipolar disorder often have abnormal thyroid gland function.Because too much or too little thyroid hormone alone can lead to mood and energy changes, it is important that thyroid levels are carefully monitored by a physician.

People with rapid cycling tend to have co-occurring thyroid problems and may need to take thyroid pills in addition to their medications for bipolar disorder. Also, lithium treatment may cause low thyroid levels in some people, resulting in the need for thyroid supplementation.

Medication Side Effects

Before starting a new medication for bipolar disorder, always talk with your psychiatrist and/or pharmacist about possible side effects. Depending on the medication, side effects may include weight gain, nausea, tremor, reduced sexual drive or performance, anxiety, hair loss, movement problems, or dry mouth. Be sure to tell the doctor about all side effects you notice during treatment. He or she may be able to change the dose or offer a different medication to relieve them. Your medication should not be changed or stopped without the psychiatrist's guidance.

Psychosocial Treatments

As an addition to medication, psychosocial treatments”including certain forms of psychotherapy (or "talk" therapy)”are helpful in providing support, education, and guidance to people with bipolar disorder and their families. Studies have shown that psychosocial interventions can lead to increased mood stability, fewer hospitalizations, and improved functioning in several areas. A licensed psychologist, social worker, or counselor typically provides these therapies and often works together with the psychiatrist to monitor a patient's progress. The number, frequency, and type of sessions should be based on the treatment needs of each person.

Psychosocial interventions commonly used for bipolar disorder are cognitive behavioral therapy, psychoeducation, family therapy, and a newer technique, interpersonal and social rhythm therapy. NIMH researchers are studying how these interventions compare to one another when added to medication treatment for bipolar disorder.

• Cognitive behavioral therapy helps people with bipolar disorder learn to change inappropriate or negative thought patterns and behaviors associated with the illness.
• Psychoeducation involves teaching people with bipolar disorder about the illness and its treatment, and how to recognize signs of relapse so that early intervention can be sought before a full-blown illness episode occurs. Psychoeducation also may be helpful for family members.
• Family therapy uses strategies to reduce the level of distress within the family that may either contribute to or result from the ill person's symptoms.
• Interpersonal and social rhythm therapy helps people with bipolar disorder both to improve interpersonal relationships and to regularize their daily routines. Regular daily routines and sleep schedules may help protect against manic episodes.
• As with medication, it is important to follow the treatment plan for any psychosocial intervention to achieve the greatest benefit.

Other Treatments

• In situations where medication, psychosocial treatment, and the combination of these interventions prove ineffective, or work too slowly to relieve severe symptoms such as psychosis or suicidality, electroconvulsive therapy (ECT) may be considered. ECT may also be considered to treat acute episodes when medical conditions, including pregnancy, make the use of medications too risky. ECT is a highly effective treatment for severe depressive, manic, and/or mixed episodes. The possibility of long-lasting memory problems, although a concern in the past, has been significantly reduced with modern ECT techniques. However, the potential benefits and risks of ECT, and of available alternative interventions, should be carefully reviewed and discussed with individuals considering this treatment and, where appropriate, with family or friends.
  
• Herbal or natural supplements, such as St. John's wort (Hypericum perforatum), have not been well studied, and little is known about their effects on bipolar disorder. Because the FDA does not regulate their production, different brands of these supplements can contain different amounts of active ingredient. Before trying herbal or natural supplements, it is important to discuss them with your doctor. There is evidence that St. John's wort can reduce the effectiveness of certain medications. In addition, like prescription antidepressants, St. John's wort may cause a switch into mania in some individuals with bipolar disorder, especially if no mood stabilizer is being taken.
• Omega-3 fatty acids found in fish oil are being studied to determine their usefulness, alone and when added to conventional medications, for long-term treatment of bipolar disorder.

Anyone with bipolar disorder should be under the care of a psychiatrist skilled in the diagnosis and treatment of this disease. Other mental health professionals, such as psychologists, psychiatric social workers, and psychiatric nurses, can assist in providing the person and family with additional approaches to treatment.

Help can be found at:

• University or medical school affiliated programs
• Hospital departments of psychiatry
• Private psychiatric offices and clinics
• Health maintenance organizations (HMOs)
• Offices of family physicians, internists, and pediatricians
• Public community mental health centers

People with bipolar disorder may need help to get help.

• Often people with bipolar disorder do not realize how impaired they are, or they blame their problems on some cause other than mental illness.
• A person with bipolar disorder may need strong encouragement from family and friends to seek treatment. Family physicians can play an important role in providing referral to a mental health professional.
• Sometimes a family member or friend may need to take the person with bipolar disorder for proper mental health evaluation and treatment.
• A person who is in the midst of a severe episode may need to be hospitalized for his or her own protection and for much-needed treatment. There may be times when the person must be hospitalized against his or her wishes.
• Ongoing encouragement and support are needed after a person obtains treatment, because it may take a while to find the best treatment plan for each individual.
• In some cases, individuals with bipolar disorder may agree, when the disorder is under good control, to a preferred course of action in the event of a future manic or depressive relapse.
• Like other serious illnesses, bipolar disorder is also hard on spouses, family members, friends, and employers.
• Family members of someone with bipolar disorder often have to cope with the person's serious behavioral problems, such as wild spending sprees during mania or extreme withdrawal from others during depression, and the lasting consequences of these behaviors.
• Many people with bipolar disorder benefit from joining support groups such as those sponsored by the National Depressive and Manic Depressive Association (NDMDA), the National Alliance for the Mentally Ill (NAMI), and the National Mental Health Association (NMHA). Families and friends can also benefit from support groups offered by these organizations

Some people with bipolar disorder receive medication and/or psychosocial therapy by volunteering to participate in clinical studies (clinical trials). Clinical studies involve the scientific investigation of illness and treatment of illness in humans. Clinical studies in mental health can yield information about the efficacy of a medication or a combination of treatments, the usefulness of a behavioral intervention or type of psychotherapy, the reliability of a diagnostic procedure, or the success of a prevention method. Clinical studies also guide scientists in learning how illness develops, progresses, lessens, and affects both mind and body. Millions of Americans diagnosed with mental illness lead healthy, productive lives because of information discovered through clinical studies. These studies are not always right for everyone, however. It is important for each individual to consider carefully the possible risks and benefits of a clinical study before making a decision to participate.

In recent years, NIMH has introduced a new generation of "real-world" clinical studies. They are called "real-world" studies for several reasons. Unlike traditional clinical trials, they offer multiple different treatments and treatment combinations. In addition, they aim to include large numbers of people with mental disorders living in communities throughout the U.S. and receiving treatment across a wide variety of settings. Individuals with more than one mental disorder, as well as those with co-occurring physical illnesses, are encouraged to consider participating in these new studies. The main goal of the real-world studies is to improve treatment strategies and outcomes for all people with these disorders. In addition to measuring improvement in illness symptoms, the studies will evaluate how treatments influence other important, real-world issues such as quality of life, ability to work, and social functioning. They also will assess the cost-effectiveness of different treatments and factors that affect how well people stay on their treatment plans.
