(Manic-Depressive Illness; Manic Depression; Manic Disorder; Manic Affective Disorder)
Bipolar disorder is a mental health condition. It is extreme swings in mood and energy. The mood changes of bipolar disorder are more severe than normal ups and downs. They can hurt relationships and make it hard to succeed at work or school.
Bipolar disorder swings between mania and depression. Mania is an increase in energy and a decreased need for sleep. The mood may be overly happy or irritable. Depression is a down mood with heavy fatigue and irritability.
There are 4 forms of bipolar disorder:
- Bipolar I disorder—Mania often immediately followed by depression. This cycle repeats. It can be severe.
- Bipolar II disorder—Less severe mania (called hypomania) that rotate with major depression.
- Bipolar disorder not otherwise specified (BP-NOS)—does not fit the description of bipolar I or bipolar II disorder.
- Cyclothymia—Hypomania that alternate with episodes of mild depression that lasts for at least 2 years.
The exact cause of bipolar disorder is unknown. Changes in genes may change how the brain works.

- Disorders of thought
The doctor will ask about your symptoms and past health. A physical exam will be done. Lab tests may be done to rule out other possible causes of symptoms. A mental health specialist will help to diagnosis bipolar disorder. It will be based on the history of symptoms.
Episodes of mania or depression will also be diagnosed as they occur. Symptoms will need to last a period of time and be severe enough to interfere with day to day life.
Treatment may help to ease mood swings . It can help to decrease effect on day to day life and avoid major complications.
Medicine called mood stabilizers is the main treatment for bipolar disorder. Some may be used during a crisis such as severe depression. Others may help with long term control. The exact plan will be based on individual needs. A medical team will work to find the medicines that have the most benefits and smallest risks. Bipolar disorder medicine may include:
- Mood stabilizers
- Antidepressants—only during depressive episodes
- Antiseizure medicines
Treatment should prevent major mood swings. It may take some time to find the best treatment plan.
Psychotherapy can give patients and their families support and help with treatment plan. Therapy may include:
- Cognitive-behavioral therapy (CBT)
- Family therapy
- Interpersonal and social rhythm therapy
It can help people stay on track with their treatment plan.
Some manic or depressive episodes can be severe. Some may also have frequent bipolar cycles. Medicine and therapy may not be effective for this. Electroconvulsive therapy (ECT) uses controlled electrical currents to reset the brain. It may be a treatment option for those with severe problems.
The cause of bipolar disorder is not clear so there are no steps to prevent it.
