Seasonal Depression Overview

Seasonal affective disorder (SAD) is a type of depression that is tied to seasons of the year. Most people with SAD are depressed only during the late fall and winter (sometimes called the "winter blues") and not during the spring or summer. A small number, however, are depressed only during the late spring and summer.

SAD is most common in young adult women, although it can affect men or women of any age. In North America, SAD may affect as many as 6 of every 100 people, more in the Northern portions of the country than in the South. Another 10-20% of people may have a milder form of seasonal mood change.

Like all types of depression, SAD can have a devastating effect on a person’s life. Fortunately, almost all people with SAD can be helped with available therapies.
