factors besides genes are also at work. Rather, it is likely that many different genes and a person’s environment are involved. However, scientists do not yet fully understand how these factors interact to cause bipolar disorder.
Brain Structure and Functioning
Brain-imaging studies are helping scientists learn what happens in the brain of a person with bipolar disorder. Newer brain-imaging tools, such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET), allow researchers to take pictures of the living brain at work. These tools help scientists study the brain’s structure and activity.
Some imaging studies show how the brains of people with bipolar disorder may differ from the brains of healthy people or people with other mental disorders. For example, one study using MRI found that the pattern of brain development in children with bipolar disorder was similar to that in children with “multi-dimensional impairment,” a disorder that causes symptoms that overlap somewhat with bipolar disorder and schizophrenia. This suggests that the common pattern of brain development may be linked to general risk for unstable moods.
Learning more about these differences, along with information gained from genetic studies, helps scientists better understand bipolar disorder. Someday scientists may be able to predict which types of treatment will work most effectively. They may even find ways to prevent 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.
A person may be having an episode of bipolar disorder if he or she has a number of manic or depressive symptoms for most of the day, nearly every day, for at least one or two weeks. Sometimes symptoms are so severe that the person cannot function normally at work, school, or home.
Symptoms of mania or a manic episode include:
- A long period of feeling “high,” or an overly happy or outgoing mood
- Extremely irritable mood, agitation, feeling “jumpy” or “wired.”
- Talking very fast, jumping from one idea to another, having racing thoughts
- Being easily distracted
- Increasing goal-directed activities, such as taking on new projects
- Being restless
- Sleeping little
- Having an unrealistic belief in one’s abilities
- Behaving impulsively and taking part in a lot of pleasurable,?high-risk behaviors, such as spending sprees, impulsive sex, and impulsive business investments.
Symptoms of depression or a depressive episode include:
- A long period of feeling worried or empty
- Loss of interest in activities once enjoyed, including sex.
- Feeling tired or “slowed down”
- Having problems concentrating, remembering, and making decisions
- Being restless or irritable
- Changing eating, sleeping, or other habits
- Thinking of death or suicide, or attempting suicide.
Exams and Tests
The first step in getting a proper diagnosis is to talk to a doctor, who may conduct a physical examination, an interview, and lab tests. Bipolar disorder cannot currently be identified through a blood test or a brain scan, but these tests can help rule out other contributing factors, such as a stroke or brain tumor. If the problems are not caused by other illnesses, the doctor may conduct a mental health evaluation. The doctor may also provide a referral to a trained mental health professional, such as a psychiatrist, who is experienced in diagnosing and treating bipolar disorder.
The doctor or mental health professional should conduct a complete diagnostic evaluation. He or she should discuss any family history of bipolar disorder or other mental illnesses and get a complete history of symptoms. The doctor or mental health professionals should also talk to the person’s close relatives or spouse and note how they describe the person’s symptoms and family medical history.
People with bipolar disorder are more likely to seek help when they are depressed than when experiencing mania or hypomania.
Therefore, a careful medical history is needed to assure that bipolar disorder is not mistakenly diagnosed as major depressive disorder, which is also called unipolar depression. Unlike people with bipolar disorder, people who have unipolar depression do not experience mania. Whenever possible, previous records and input from family and friends should also be included in the medical history.
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.
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. In some states, clinical psychologists, psychiatric nurse practitioners, and advanced psychiatric nurse specialists can also prescribe medications. Check with your state’s licensing agency to find out more.
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.
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 FDA.
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.23, 24 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.
Valproic acid, lamotrigine, and other anticonvulsant medications have an FDA warning. The warning states that their use may increase the risk of suicidal thoughts and behaviors. People taking anticonvulsant medications for bipolar or other illnesses should be closely monitored for new or worsening symptoms of depression, suicidal thoughts or behavior, or any unusual changes in mood or behavior. People taking these medications should not make any changes without talking to their health care professional.
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:
- Cognitive-behavioral therapy (CBT) helps people with bipolar disorder learn to change harmful or negative thought patterns and behaviors.
- 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.
- 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.
- 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.
- Electroconvulsive Therapy (ECT)—For cases in which medication and/or psychotherapy does not work, electroconvulsive therapy (ECT) may be useful. ECT, formerly known as “shock therapy,” once had a bad reputation. But in recent years, it has greatly improved and can provide relief for people with severe bipolar disorder who have not been able to feel better with other treatments. Before ECT is administered, a patient takes a muscle relaxant and is put under brief anesthesia. He or she does not consciously feel the electrical impulse administered in ECT. On average, ECT treatments last from 30–90 seconds. People who have ECT usually recover after 5–15 minutes and are able to go home the same day.
- Sometimes ECT is used for bipolar symptoms when other medical conditions, including pregnancy, make the use of medications too risky. ECT is a highly effective treatment for severely depressive, manic, or mixed episodes, but is generally not a first-line treatment.
- ECT may cause some short-term side effects, including confusion, disorientation, and memory loss. But these side effects typically clear soon after treatment. People with bipolar disorder should discuss possible benefits and risks of ECT with an experienced doctor.
- 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.
Left untreated, bipolar disorder can result in serious problems that affect every area of your life. These can include:
- Problems related to substance and alcohol abuse
- Legal problems
- Financial problems
- Relationship troubles
- Isolation and loneliness
- Poor work or school performance
- Frequent absences from work or school
When to Contact a Medical Professional
Bipolar disorder is complex and hard to diagnose because it has many phases and symptoms. Sometimes it is misdiagnosed as only depression (unipolar depression), because people are more likely to seek treatment during a period of depression.
After you are diagnosed with bipolar disorder, it is important to keep a long-term relationship with your doctor or therapist to make sure that your treatment is consistent and that your medicines can be adjusted as needed.
If you have bipolar disorder, call 911or other emergency services if you:
- Think you cannot stop from harming yourself or someone else.
- Hear voices that are new or more upsetting than normal.
- Want to commit suicide, or you know someone who has mentioned wanting to commit suicide.
Warning signs of suicide include:
- Use of illegal drugs or drinking alcohol heavily.
- Talking, writing, or drawing about death, including writing suicide notes and speaking of items that can cause physical harm, such as pills, guns, or knives.
- Spending long periods of time alone.
- Giving away possessions.
- Acting aggressive or suddenly appearing calm.
There’s no sure way to prevent bipolar disorder. However, getting treatment at the earliest sign of a mental health disorder can help prevent bipolar disorder or other mental health conditions from worsening.
If you’ve been diagnosed with bipolar disorder, some strategies can help prevent minor episodes from becoming full-blown episodes of mania or depression:
- Pay attention to warning signs. Addressing symptoms early on can prevent episodes from getting worse. You and your caregivers may have identified a pattern to your bipolar episodes and what triggers them. Call your doctor if you feel you’re falling into an episode of depression or mania. Involve family members or friends in watching for warning signs.
- Avoid drugs and alcohol. Even though you may initially feel better, using alcohol or street drugs makes your symptoms more likely to come back.
- Take your medications exactly as directed. Medications can have unwanted side effects, and you may feel unhappy about having a mental health condition that requires lifelong treatment. During periods when you feel better, you may be tempted to stop treatment. This can have immediate consequences — you may become very depressed, feel suicidal, or go into a manic or hypomanic episode. If you think you need to make a change, call your doctor.
- Check first before taking other medications. Call the doctor who’s treating you for bipolar disorder before you take medications prescribed by another doctor. Sometimes other medications trigger episodes of bipolar disorder or may interfere with medications you’re already taking to treat bipolar disorder.
Major mood swings may signal the presence of bipolar disorder. According to research or other evidence, the following self-care steps may help you restore the balance and gain control:
What You Need To Know:
- Fight back with fish oil
If your healthcare provider agrees, try improving bipolar symptoms with fish oil capsules delivering 9.6 grams of omega-3 fatty acids per day along with your medications
- Work in a workout
Discuss exercise with your medical provider to see if it might be beneficial for you
