Which sign is commonly associated with depression?

Depression is often characterized by a significant decrease in interest or pleasure in activities that were once enjoyable, a symptom known as anhedonia. When someone is experiencing depression, they might find that they no longer have the motivation to engage in hobbies, social interactions, or other activities that they previously found fulfilling. This lack of interest can affect various aspects of life, from personal relationships to work performance.

In contrast, the other options reflect states of mood that are typically opposite to those experienced during depression. For instance, constant energy and enthusiasm, a high level of social activity, and persistent happiness are all indicative of a positive emotional state, which does not align with the symptoms of depression. Understanding the symptoms of depression, such as the lack of interest in activities, is crucial for recognizing the condition and facilitating support or treatment for those affected.
