Anhedonia refers to:

• A. Loss of energy
• B. Loss of interest and pleasure in usually enjoyable activities
• C. Loss of appetite
• D. Sleep disturbance

Answer: (B)

Anhedonia is the decreased ability to experience pleasure or interest in activities that are usually enjoyable. This symptom reflects a blunted or diminished experience of reward, which is why someone may no longer find hobbies, social activities, or intimate experiences gratifying.

It’s distinct from other common symptoms such as fatigue (loss of energy), appetite changes (loss of appetite), or sleep problems (sleep disturbance). Those describe disruptions in energy, eating, or sleep, whereas anhedonia specifically targets the pleasure response and motivation.

In practice, recognizing anhedonia helps explain why a person withdraws from activities they once enjoyed, even if their mood isn’t overtly sad.
