Types of Depression


How Is Seasonal Depression (SAD) Different From Other Types of Depression?

Seasonal depression, often called seasonal affective disorder or SAD, is a depression that occurs each year at the same time. It usually starts in the fall or winter and ends in spring or early summer. It is more than just "the winter blues" or "cabin fever." A rare form of SAD, known as "summer depression," begins in late spring or early summer and ends in fall.

For in-depth information, see WebMD's Seasonal Depression (SAD).

What Is Psychotic Depression?

With psychotic depression, delusional thoughts (false, fixed beliefs) or other symptoms of psychosis (such as hallucinations) accompany the symptoms of depression. With psychotic depression, there's a break with reality.  For example, someone may feel that they are being punished for having sinned or committing a crime, or they may believe their body is decaying.

What Is Postpartum Depression?

As many as 75% of new moms get the "baby blues." But about one in 10 moms develop a more serious condition called postpartum depression. According to the National Institute of Mental Health, postpartum depression is diagnosed when a new mother develops a major depressive episode within one month after delivery.

No matter what depression symptoms you might have, it's important to talk to your doctor. Getting an accurate medical diagnosis and effective treatment is crucial in managing depression.
