Bipolar Disorder: Treatment Part 1

Bipolar disorder is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. Symptoms of bipolar disorder are severe, but it can be treated, and people with this illness can lead full and productive lives.

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

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.

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) 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, 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.
• More recently, the anticonvulsant lamotrigine received FDA approval for maintenance treatment of bipolar disorder.
• Other anticonvulsant medications, including gabapentin, topiramate, and oxcarbazepine 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.

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.

Valproic acid may increase levels of testosterone (a male hormone) in teenage girls and lead to polycystic ovary syndrome (PCOS) in women who begin taking the medication before age 20. PCOS causes a woman's eggs to develop into cysts, or fluid filled sacs that collect in the ovaries instead of being released by monthly periods. This condition can cause obesity, excess body hair, disruptions in the menstrual cycle, and other serious symptoms. Most of these symptoms will improve after stopping treatment with valproic acid. Young girls and women taking valproic acid should be monitored carefully by a doctor.

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, 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, 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 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 and ziprasidone are other atypical antipsychotics that may also be prescribed for controlling manic or mixed episodes.

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.
