The correct answer provides the definition of the two differing Bipolar I and Bipolar II disorders.

Those with rapid cycling bipolar disorder are classified as such when they have at least four manic or depressive episodes in one year.

Sarah's symptoms are consistent with “bipolar disorder,” which includes alternating between periods of depression and mania. By definition, a manic episode must last at least one week and not be induced by drugs or alcohol. Even though Sarah experiences periods of “depression,” bipolar disorder is the more appropriate diagnosis due to her manic episodes. “Borderline personality disorder” includes symptoms related to instability in relationships, emotions, and self-image. “Generalized anxiety disorder” is characterized by excessive anxiety regarding a number of things that induces impaired functioning. Last, “schizophrenia” is a psychotic disorder that involves at least two of the following symptoms: hallucinations, delusions, disorganized thinking, disorganized behavior, and emotional flattening.

Bipolar disorder has several sub-types. Bipolar I is defined by manic episodes that last at least a week, typically alternating with episodes lasting at least 2 weeks. Bipolar II disorder is characterized by a pattern of depressive episodes with some hypomanic episodes, but no full-blown manic episodes. Four or more episodes of depression, mania, or hypomania, all within one year, is called rapid-cycling bipolar disorder. Alternating episodes of depression and hypomania that last at least 2 years (but do not meet criteria for Bipolar I) is known as cyclothymic disorder.

Individuals with Bipolar I disorder must have at least one manic episode. Bipolar II is characterized by major depression and hypomania, a state of slightly less agitation than mania, but cannot have had a manic episode.

A hypomanic episode is a period of persistently elevated or irritable mood that lasts for at least four days. This episode is markedly different from the person's usual mood, and it is not severe enough to cause occupational hazards or require hospitalization.

Bipolar disorder involves periods of depression alternating with periods of mania, which can involve unusually elevated mood reckless behavior. Historically, bipolar disorder has been known as manic depression. Periods of mania do not occur in a depressive disorder.

Dysthemia (mild-grade depression) and hypomania (which is not as drastic as some other frank mania experiences) can cycle back and forth in "cyclothymia."

Mood stabilizers are effective in stabilizing patients experiencing a manic period, and in maintaining symptom remission when the manic period has ended. While antipsychotic medication can also be prescribed to quell psychotic symptoms (e.g. hallucinations) that may occur in manic periods it is not the most common course of treatment.

**"**Hallucinating" is the correct answer. Hallucinating is not a common attribute of a manic state. It is more commonly paired with schizophrenia. During a manic state, bi-polar patients are elated, often talking a lot, not sleeping, engaging in promiscuous activities, and being more creative.
