Understanding Seasonal Affective Disorder (SAD)

Seasonal affective disorder (SAD) is a subtype of depression that typically manifests with symptoms during the fall and winter months, subsiding in spring and summer. It is distinct from major depressive disorder but shares similar characteristics, including persistent low mood and lethargy. Prevalence rates suggest that approximately 5% of adults in the U.S. are diagnosed with SAD, and factors such as geographical location and gender significantly influence its severity. Interestingly, women are more commonly affected, with a noted four-to-one ratio, and those living farther from the equator exhibit higher incidence rates due to decreased daylight exposure.
