Bipolar Disorder

What is Bipolar Disorder?
Bipolar Disorder, also known as manic-depressive illness, is a serious medical illness that causes shifts in a person's mood, energy, and ability to function. Different from the normal ups and downs that everyone goes through, the symptoms of bipolar disorder are severe. More about Bipolar Disorder »
Signs & Symptoms
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. More about Signs & Symptoms »

How Is Bipolar Disorder Treated?
Index Previous Page Next page
Most people with bipolar disorder—even those with the most severe forms—can achieve substantial stabilization of their mood swings and related symptoms with proper treatment.10,11,12 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
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.10 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 20.13 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.14 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.15 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.16 Other research has supported the efficacy of olanzapine for acute mania, an indication that has recently received FDA approval.17 Olanzapine may also help relieve psychotic depression.18
· 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.4 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.12 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.19
· 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.20 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.21
· 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.22
A Long-Term Illness That Can Be Effectively Treated
Even though episodes of mania and depression naturally come and go, it is important to understand that bipolar disorder is a long-term illness that currently has no cure. Staying on treatment, even during well times, can help keep the disease under control and reduce the chance of having recurrent, worsening episodes.
What Are the Symptoms of Bipolar Disorder?
Index Previous Page Next page
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.
