Which disorder is characterized by persistent low mood, loss of interest in activities, and is often treated with antidepressants?

• A. Generalized Anxiety Disorder
• B. Panic Disorder
• C. PTSD
• D. Clinical Depression

Answer: (D)

Persistent low mood with loss of interest in activities signals a depressive disorder. When someone experiences ongoing sadness or a sense of emptiness for an extended period, along with diminished pleasure in things they once enjoyed, it typically leads to noticeable impairment in daily functioning. Antidepressants are commonly used because they help adjust mood regulation in the brain, often improving energy, motivation, and overall mood, and are frequently paired with therapy for best results.

The other disorders described emphasize anxiety or trauma. Generalized Anxiety Disorder centers on excessive, persistent worry and physical symptoms of anxiety; Panic Disorder involves recurrent panic attacks and fear of having another; PTSD arises after exposure to a traumatic event, with intrusive memories and hyperarousal. Those conditions are defined more by anxiety or trauma-related features than by the core depressed mood and anhedonia seen here, even though depression can occur alongside them.
