'''Bipolar II disorder''' is a type of bipolar spectrum disorder characterized by at least one hypomanic episode and one major depressive episode. It differs from [[Bipolar I disorder]] in that individuals with Bipolar II have never experienced a full manic episode. If a full manic episode is experienced, the diagnosis would be changed to Bipolar I disorder.

== Definition and Diagnosis == 

Bipolar II disorder is diagnosed when a person experiences at least one episode of hypomania and at least one episode of major depression. A key distinguishing feature of this disorder is that the individual must never have experienced a full manic episode.

Hypomania is a mood state characterized by persistent and pervasive elevated, expansive, or irritable mood. It is less severe than a full-blown manic episode, but it still results in a noticeable difference in behavior compared to the person's baseline mood.

Major depression involves a persistent feeling of sadness or a lack of interest in outside stimuli. It is characterized by the presence of five or more depressive symptoms over a two-week period.

It's important to note that while hypomanic episodes in Bipolar II disorder are not as intense as manic episodes seen in Bipolar I disorder, the depressive episodes are often more severe and longer-lasting.

== Symptoms == 

=== Hypomania ===
During a hypomanic episode, individuals may experience:

* Increased energy, activity, and restlessness
* Euphoric mood
* Extreme irritability
* Racing thoughts, rapid speech
* Decreased need for sleep

* Persistent sad, anxious, or "empty" mood
* Feelings of hopelessness or pessimism
* Feelings of guilt, worthlessness, or helplessness
* Decreased energy, fatigue, feeling "slowed down"
* Difficulty concentrating, remembering, or making decisions
* Insomnia, waking up too early, or oversleeping
== Treatment == 

Bipolar II disorder is typically treated with a combination of medication and psychotherapy. Mood stabilizers such as [[lithium (medication)|lithium]] or anticonvulsant medications can be effective in preventing episodes of hypomania and depression. In some cases, antidepressants may be used, but they can sometimes trigger a hypomanic episode. Psychotherapy, such as cognitive behavioral therapy or family-focused therapy, can be beneficial in helping individuals manage symptoms and cope with the disorder.
