A 25-year-old female reports feeling persistently sad, losing interest in hobbies, and feeling lethargic every year starting from late fall until spring for the last two years. These symptoms interfere with her academic performance. What is the likely diagnosis and recommended interventions?
The patient's symptoms of recurring depression and lethargy during the fall and winter months are indicative of Seasonal Affective Disorder (SAD). Recommended interventions include light therapy, which has proven to be particularly effective for SAD, cognitive-behavioral therapy, and possibly antidepressant medication. Ensuring adequate physical activity, exposure to daylight, and maintaining social connections can also help to manage symptoms.
