Answer to Question 1
ANS: A
Bipolar disorder is a cluster of disorders that reflect a marked flux in mood. A manic episode is a distinct period of a persistently elevated, expansive, or irritable mood lasting at least 1 week. This mood must coexist with at least three of the following symptoms: inflated self-esteem or grandiosity, decreased need for sleep, pressure of speech, flight of ideas, distractibility, increased involvement in goal-directed activities or psychomotor agitation, and excessive involvement in pleasurable activities with a high potential for painful consequences.
Answer to Question 2
ANS: A
The coexistence within a major depressive episode of at least three manic symptoms (insufficient to satisfy criteria for a manic episode) is now acknowledged by the specifier with mixed features. The presence of mixed features in an episode of major depressive disorder increases the likelihood that the illness exists in a bipolar spectrum; however, if the individual concerned has never met criteria for a manic or hypomanic episode, the diagnosis of major depressive disorder is retained. Mixed episodes are more prevalent in adolescents and young adults than in older adults.
