🆚 Go to Comparative Table 🆚

The main difference between bipolar 1 and 2 disorders lies in the severity of the manic episodes and the presence of depressive episodes. Here are the key differences between the two:

  • Bipolar 1 Disorder: People with bipolar 1 disorder experience a manic episode (a period of extremely high energy, restlessness, and trouble concentrating), which may or may not be followed by a depressive episode. They may also experience psychosis, which is more likely to result in hospitalization, especially during manic episodes. Treatment for bipolar 1 disorder typically involves mood stabilizers, therapy, and antipsychotics.
  • Bipolar 2 Disorder: People with bipolar 2 disorder experience a hypomanic episode (a less severe form of mania) and a major depressive episode. They are less likely to experience psychosis and hospitalization during depressive episodes. Treatment for bipolar 2 disorder usually involves mood stabilizers and therapy.

In summary, the main differences between bipolar 1 and 2 disorders are the severity of the manic episodes and the presence of depressive episodes. People with bipolar 1 disorder experience more severe highs (mania) and may not have depressive episodes, while those with bipolar 2 disorder experience a less severe high (hypomania) and have depressive episodes.
