ReviewSeasonal Affective Disorder: Common Questions and Answers.
Seasonal affective disorder is a mood disorder that is a subtype or qualifier of major depressive disorder or bipolar disorder in the Diagnostic and Statistical Manual of Mental Disorders. It is characterized by depressive symptoms that occur at a specific time of year (typically fall or winter) with full remission at other times of year (typically spring or summer). Possible risk factors include family history, female sex, living at a more northern latitude, and young adulthood (18 to 30 years of age). ⋯ If seasonal affective disorder recurs, long-term treatment or preventive intervention is typically indicated, and bupropion appears to have the strongest evidence supporting long-term use. Continuing light therapy or other antidepressants is likely beneficial, although evidence is inconclusive. Evidence is also inconclusive for psychotherapy and vitamin D supplementation.
