What Are the 5 Types of Bipolar Disorder
Bipolar disorder is a mood disorder characterized by episodes of mania and depression

Bipolar disorder is a mood disorder characterized by episodes of mania and depression. Extreme happiness or excitement (mania) and melancholy (depression) are typical symptoms of mood episodes. People with bipolar disorder may have normal moods in between the manic or depressive episodes.

The five types of bipolar disorder are bipolar I, bipolar II, cyclothymic disorder, other specified bipolar and related disorder, and unspecified bipolar and related disorder:

  1. Bipolar I: Characterized by alternating episodes of severe depression and intense mania. Intense manic episodes may last for 7 or more days and need immediate medical attention. Depressive symptoms may last for about 2 weeks 
  2. Bipolar II: Involves severe depression but less intense mania (hypomania or hypomanic episodes). People with bipolar II tend to get more depressive episodes than those with hypomania.
  3. Cyclothymic disorder: Characterized by a less severe form of mania and depression. Depression and mania are not as severe as full manic and depressive episodes. Symptoms may last for 2 years.
  4. Other specified bipolar and related disorder: Refers to a type of bipolar disorder in which there are symptoms that do not fit into the other categories. For example, rapid cycling may occur, where four or more mood episodes occur within 12 months. These episodes must last for some time to be considered distinct episodes. The person may experience four or more episodes of mania or depression in one year.
  5. Unspecified bipolar and related disorder: Similar to other specified bipolar and related disorder but used when there is not enough information to make a specific diagnosis. The person may experience symptoms of mania and depression at the same time.

How is bipolar disorder treated?

Management of bipolar disorder involves a combination of medications and psychotherapy or counseling. Treatment depends on the type of bipolar disorder.

Medications used to treat bipolar disorders include:

In some cases, psychotherapy has proven beneficial in treating mood episodes. Another therapy is psychoeducation in which patients and their families are educated regarding symptoms and importance of medication compliance.

In the case of failed medication and psychotherapy, other methods such as electroconvulsive therapy may be used, in which a small electric current is passed through the brain to treat the disorder.

Recognizing and treating symptoms early are crucial to prevent complications such as addictions and suicide.
