• A. A period characterized by elevated, expansive, or irritable mood lasting at least a week and often including increases in activity or psychomotor agitation, talkativeness, flight of ideas or racing thoughts, inflated self-esteem or grandiosity, risk-taking, and decreased need for sleep; experiencing one of these is required for a diagnosis of Bipolar I disorder
• B. A mood state with chronic sadness and fatigue
• C. A short-lived episode of anxiety without mood changes
• D. A psychotic episode with no mood changes

Answer: (A)

The key idea here is recognizing the defining manic episode criteria used to diagnose Bipolar I disorder. A manic episode involves a distinct period of abnormally elevated, expansive, or irritable mood with increased energy or activity that lasts at least one week, and includes several associated symptoms such as grandiosity, decreased need for sleep, pressured speech, racing thoughts, increased goal-directed activity, and risky behaviors. For Bipolar I, having at least one manic episode is required for the diagnosis, regardless of depressive episodes. The described option captures this pattern precisely: it notes the mood criteria, the minimum one-week duration, and the constellation of accompanying symptoms like flight of ideas, grandiosity, and decreased need for sleep. The other choices point to a depressive state, a brief anxiety episode, or a psychotic episode without mood changes, which do not fit the manic criteria.
