Episode notes
SAD Is A Seasonal Major Depression
- Seasonal affective disorder (SAD) is a recognized subtype of major depressive disorder with a seasonal pattern.
- It most often begins in young adulthood, is more common in women, and usually appears in winter but can rarely occur in summer.
Suicide Peaks In Spring/Summer, Not Holidays
- Contrary to myth, suicides do not spike during December and are more common in spring and summer.
- Proposed explanations include greater energy to act and seasonal flares of autoimmune illnesses in warmer months.
Light Alters Serotonin And Melatonin
- Reduced sunlight lowers serotonin production and increases melatonin, disrupting mood and energy.
- In people with SAD the serotonin transporter doesn't downregulate in winter, so relatively less serotonin causes depressive symptoms.
