Bipolar Disorder

(Manic-Depressive Illness; Manic Depression; Manic Disorder; Manic Affective Disorder)
  • Definition

    Bipolar disorder is a mental health condition marked by extreme swings in mood, energy, and the ability to function. The mood changes of bipolar disorder are more dramatic than normal ups and downs. They can hurt relationships and cause poor job or school performance.
    The two mood extremes of bipolar disorder are mania and depression. In mania, one of the defining symptoms is an increase in energy and a decreased need for sleep. The mood may be overly happy or irritable. In depression , a down mood with fatigue takes over, often accompanied by irritability.
    There are four forms of this condition:
    • Bipolar I disorder—Recurrent episodes of mania often immediately followed by depression; episodes can be severe.
    • Bipolar II disorder—Episodes of less severe mania (called hypomania) that alternate with episodes of major depression.
    • Bipolar disorder not otherwise specified (BP-NOS)—The person has symptoms of bipolar disorder, but the symptoms do meet the specific criteria for bipolar I or bipolar II disorder
    • Cyclothymia—Episodes of hypomania that alternate with episodes of mild depression that last for at least two years
  • Causes

    The cause of bipolar disorder is unknown. This condition tends to run in families. Specific genes may play a role. It is most likely many different genes that act together.

  • Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done. In some cases, lab tests are ordered to rule out other causes of your symptoms. You may be referred to a mental health specialist. Diagnosis of bipolar disorder is based on:
    • Presence of certain symptoms over time
    • Absence of other causes, such as some medications and certain conditions
    • Family history of bipolar disorder
    Mania is diagnosed if:
    • Mood is elevated and there are three or more manic symptoms (listed above)
      • If the mood is irritable, not elevated, four symptoms must be present for a diagnosis of mania
    • Symptoms last for most of the day, nearly every day, for one week or longer
    • Symptoms cause problems in day-to-day functioning
    A depressive episode is diagnosed if:
    • There are five or more of the depressive symptoms (listed above)
    • Symptoms last for most of the day, nearly every day, for a period of two weeks or longer
    • Symptoms cause problems in day-to-day functioning
  • Treatment

    Talk with your doctor about the best plan for you. Options may include:
    Medications
    The primary treatment is with medications called mood stabilizers. There are many different types and combinations of medications, which must be tailored by your doctor to target your symptoms. Examples of common medications used to treat bipolar disorder include:
    • Mood stabilizers
    • Antiseizure medications
    • Benzodiazepines
    • Antidepressants
    • Antipsychotics
    The plan is based on the pattern of the illness. Treatment may need to be continued indefinitely. It should prevent significant mood swings.
    Psychotherapy
    Psychotherapy is often an integral component of a comprehensive treatment plan. Therapy may include:
    Electroconvulsive Therapy
    Electroconvulsive therapy may be effective when medications fail. It can be used for both mania and depression.
  • Prevention

    There are no current guidelines to prevent bipolar disorder. Taking your daily medications and following your treatment plan can help prevent future mood swings.
