What is a notable characteristic of Seasonal Affective Disorder?

Seasonal Affective Disorder (SAD) is characterized primarily by its timing; it typically arises during specific seasons, most commonly the fall and winter months when sunlight exposure decreases. The correct understanding of SAD highlights that symptoms generally appear during this seasonal change and improve with the arrival of spring or summer, rather than being linked to a specific stressor.

The choice reflecting onset within three months of a stressor may relate to other mood disorders, like Adjustment Disorder, but does not accurately capture the nature of SAD, which is strictly tied to seasonal changes rather than immediate stressor events.

The symptoms of SAD include depressed mood, loss of interest or pleasure in activities, changes in appetite or weight, sleep disturbances, and difficulty concentrating, all of which are consistent with major depressive episodes, but limited to certain seasons. Thus, recognizing that SAD primarily influences individuals during certain months is a crucial aspect of its diagnosis and understanding.
