Question

BlackTom AI · Accepted Answer

Bipolar I disorder is defined by the presence of one or more manic episodes, and these manic episodes commonly alternate with major depressive episodes. A manic episode is an abnormally elevated, expansive, or irritable mood with increased energy or activity lasting at least one week (or any duration if hospitalization is required) accompanied by symptoms such as decreased need for sleep, grandiosity, pressured speech, flight of ideas, distractibility, increased goal-directed activity, or risky behaviors. A major depressive episode involves at least two weeks of depressed mood or loss of interest plus other symptoms (sleep/appetite change, low energy, feelings of worthlessness, impaired concentration, suicidal ideation).

Step-by-step reasoning:
1. Identify the mood states described: “manic episodes” and “depressive episodes.” These are full-threshold mood episodes recognized in DSM diagnostic categories.
2. Match these to diagnostic categories: Bipolar I requires at least one manic episode; depressive episodes often occur as well. Bipolar II requires hypomanic episodes (less severe than mania) plus major depressive episodes. Cyclothymia involves chronic, milder hypomanic and depressive symptoms that do not meet full episode criteria. Major depressive disorder involves depressive episodes only, with no history of mania or hypomania. Complicated (prolonged) grief is a bereavement-related disorder, not characterized by alternating full manic and depressive episodes.
3. Therefore, the disorder explicitly characterized by alternating manic and depressive episodes (i.e., presence of mania) is Bipolar I.

Why the correct answer is correct:
- Bipolar I is the prototypical disorder with full manic episodes that can alternate with major depressive episodes, matching the stem.

Why other options are incorrect:
- b. Major depressive disorder: involves depressive episodes only, no mania/hypomania.
- c. Complicated grief: involves persistent grief reactions, not cycling mania/depression.
- d. Cyclothymia: involves chronic, mild mood swings (hypomanic and subthreshold depressive symptoms), not full manic episodes.

Conclusion: The correct choice is a. bipolar I disorder, which matches the provided answer.
