Which term best fits a chronic mood disturbance with recent onset that may be tied to a specific event?

• A. Anxiety
• B. Hallucinations
• C. Bleeding (Hematologic)
• D. Depression

Answer: (D)

A mood disturbance that is persistent yet can begin after a specific event points toward depression as the best fit. Depression involves a sustained change in mood—often a prolonged feeling of sadness or loss of interest—that can be triggered by stressors or a recent life event, fitting the idea of a mood change tied to something that happened. Anxiety centers on pervasive worry and fear rather than a persistent low mood. Hallucinations are perceptual experiences not tied to mood. Bleeding is unrelated to mood or psychiatric symptoms. So, the term that best matches a chronic mood disturbance with recent onset that may be linked to a specific event is depression.
