Which of the following is a common symptom of major depressive disorder?

Loss of interest in enjoyable activities is a hallmark symptom of major depressive disorder. Individuals experiencing this condition often find that activities they once enjoyed become unappealing or feel no pleasure in them. This symptom, known as anhedonia, significantly impacts a person's quality of life and can contribute to feelings of sadness and despair. Recognizing this symptom is crucial for accurate diagnosis and effective treatment, as it helps differentiate major depressive disorder from other mood-related issues. Other options, such as inflated self-esteem, increased energy and excitement, and extroverted social interactions, are typically not associated with major depressive disorder; rather, they might be indicators of mania or hypomania, which are more characteristic of bipolar disorder.
