What is Seasonal Affective
Disorder?
Seasonal affective disorder or SAD is a major form
of depression that occurs at the same time each year with the changing
of the seasons. It effects 4 to 6 percent of the general population.
Of those that experience the symptoms of SAD, women outnumber men
four to one with the disorder usually beginning in the person's
early twenties. The risk of developing SAD typically decreases as
a person ages.

apathy, sadness, lost interest in daily activities, agitation, societal
withdrawal, and trouble concentrating. Symptoms most common to SAD
include:
