What is the defining characteristic of a mood disorder?

• A. Causes anxiety, fear, or panic.
• B. Affects the person's mood as the primary symptom.
• C. Involves delusions.
• D. Results in memory loss.

Answer: (B)

Mood disorders are defined by mood being the primary symptom driving the condition. This means the dominant, persistent change is in how the person feels—depressed, manic, or alternating between these states—which significantly affects functioning. Other features may appear, but the central and defining feature is the mood disturbance itself. The other descriptions point to different problems: anxiety or panic is the hallmark of anxiety disorders; delusions are a key feature of psychotic disorders; memory loss is more associated with cognitive or neurological conditions. In mood disorders, those symptoms aren’t the defining characteristic, even though other symptoms can occur.
