تعريف
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. Bipolar disorder can be treated. Contact your doctor if you think you may have this condition.
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 (e.g., acting in a way that is outside of their normal behavior), 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
أسباب
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.
عوامل الخطر
A family history of the disorder increases your chance of developing it. Tell your doctor if you have a family member with bipolar disorder.

الأدوية
The primary treatment is with medicines called mood stabilizers. There are many different types and combinations of medicines, which must be tailored by your doctor to target your symptoms. Examples of common medicines used to treat bipolar disorder include:
- Lithium —The oldest mood stabilizer, often used as initial treatment (helps prevent manic and depressive episodes from returning)
- Antiseizure medicines—Also used as mood stabilizers instead of, or in combination with, lithium
- Lamotrigine (Lamictal)
- Valproate (Depakote)
- Carbamazepine (Tegretol)
- Other drugs that may be used to help treat mood problems in bipolar disorder include:
- Benzodiazepines—A potentially addicting class of medicines that can be used to treat agitation or insomnia, usually on a short-term basis
- Antidepressants—Used to treat depression, usually prescribed in combination with a mood stabilizer, like lithium
- Antipsychotic medicines—Used for acute manic or mixed episodes and maintenance treatment
The plan is based on the pattern of the illness. Treatment may need to be continued indefinitely. It should prevent significant mood swings.
