What are a group of psychotic disorders characterized by severe and inappropriate emotional responses, by prolonged and persistent disturbances of mood and related thought distortions?

A. Within 1 to 2 months. While some recovery may be seen within the first 1 to 2 months, it is typically an ongoing process, and significant improvements are often seen over a longer period.
B. Within 2 to 3 weeks. This timeframe is too short for significant recovery of neurologic function. Initial recovery is most rapid in the first few weeks, but continued improvement is expected over months.
C. Within 6 to 9 months. While recovery can continue up to 6 to 9 months or longer, most significant improvements in neurologic function occur within the first 3 to 6 months.
D. Within 3 to 6 months. This is the period during which the most significant recovery of neurologic function typically occurs following a stroke.

A. Bipolar disorder: The described behavior of extreme mood swings (elevated mood followed by significant depression) is characteristic of bipolar disorder.

B. Dysthymic disorder: Dysthymic disorder (now known as persistent depressive disorder) involves a chronic state of depression but does not typically feature such pronounced mood swings.

C. Hypomanic episode: A hypomanic episode would involve elevated mood but would not usually be followed by the severe depressive episode described.

D. Unipolar depression: Unipolar depression is characterized by a persistent low mood rather than the dramatic shifts described.
