What Are The Signs Of Seasonal Affective Disorder?

Seasonal affective disorder (SAD) seems to be a type of depression. It does not seem to be a constant condition. Instead, patients may only experience it during one season. The most common season for this condition appears to be the winter. Patients may notice their symptoms start in the fall and worsen during the winter. However, they may disappear at the end of winter. Although winter may be the most common time for seasonal affective disorder, cases seem to have appeared in the spring and summer as well.
