• A. Persistent happiness and elevated mood
• B. Persistent low mood and lack of interest
• C. Increased social interaction and activity
• D. Irregular sleep patterns and mood swings

Answer: (B)

The main depressive symptoms of Seasonal Affective Disorder (SAD) include persistent low mood and lack of interest, which correspond directly to the correct answer. Individuals with SAD typically experience significant depressive episodes that occur in a seasonal pattern, usually during the fall and winter months when sunlight exposure is reduced. The hallmark features of these episodes are a pervasive sense of sadness, hopelessness, and disinterest in activities that were once enjoyable.

This marked lack of interest often leads individuals to withdraw from social activities and experience a diminished capacity to feel pleasure, known as anhedonia. These symptoms can significantly impair daily functioning and overall quality of life, making it crucial to recognize and address them for effective management and treatment of the disorder. Understanding the specific mood changes associated with SAD is vital because they differ distinctly from symptoms of other mood disorders, emphasizing the seasonal pattern observed in this condition.
