There are several different types of bipolar disorder.
Bipolar I disorder refers to a condition in which an individual experiences a full-blown manic episode for at least one week and may or may not also experience depression.
Psychotic symptoms in bipolar disorder tend to reflect the extreme mood state at the time.
For example, delusions of grandiosity, such as believing one is the president or has special powers or wealth, may occur during mania; delusions of guilt or worthlessness, such as believing that one is ruined and penniless or has committed some terrible crime, may appear during depression.
Additionally, persons experiencing mania may display suddenly inflated self-esteem, decreased need for sleep, talkativeness and distractibility, and often engage in activities that have high potential for painful consequences (gambling, heavy spending, sexual indiscretions).
Hypomania is similar to mania in that the disturbance in mood and the change in functioning are observable by others, but the episode is not severe enough to cause major impairment in social or occupational functioning or to require hospitalization.
Cyclothymic disorder, or cyclothymia, refers to recurring hypomanic and depressive mood shifts over at least a two-year period in adults.
According to the National Institute of Mental Health, an estimated 4.4 percent of adults in the United States experience a bipolar disorder at some point in their lifetime.

What's more, the episode is not explainable by ingestion of a medication, drug of abuse, or medical condition.
