Bipolar II disorder involves periods of depression and periods of elevated mood, called hypomania. This is like mania but less extreme.
All forms of bipolar disorder involve shifts in mood and levels of energy and activity.
Bipolar II causes hypomania, a period in which mood and behavior are elevated beyond what most people experience. In a state of hypomania, a person may feel elated, energized, or even irritable.
Bipolar I causes mania, a more severely elevated mood than hypomania.
Experts introduced the term “bipolar II disorder” in 1994 to help doctors describe and treat the condition more effectively.
However, as scientists discover more about the condition, some have called for an end to the distinction between types I and II. They argue that it is more realistic to see bipolar disorder as a spectrum with a range of symptoms, patterns, and severities.

- structural features in the brain
Bipolar disorder is more likely to develop in a person with a close relative who has it.
Also, stress and traumatic events can contribute to triggering the condition in a person with a genetic predisposition.
According to the National Institute of Mental Health, symptoms may appear for the first time during pregnancy or after childbirth.
For a diagnosis of bipolar II, a person will need to have had at least one episode of depression and at least one hypomanic episode.
