Major depressive disorder (MDD), commonly known as clinical depression, is one of the most common mental disorders worldwide. Many different factors can contribute to a person’s depressive state and depression is often an overlapping diagnosis along with other medical conditions and/or mental disorders.

What is depression?

The most prominent symptoms of major depression are a severe and persistent low mood, profound sadness, or a sense of despair. A major depressive episode (MDE) is a period of time characterized by symptoms of major depression. The Diagnostic and Statistical Manual of Mental Disorders defines a major depressive episode as experiencing a depressed mood or loss of interest or pleasure in daily activities, accompanied by problems with sleeping, eating, energy, concentration, or self-worth for two weeks or longer.

“Sudden losses or changes can exacerbate pre-existing symptoms of depression or anxiety,” says Yesel Yoon, Ph.D., a psychologist based in New York. Depressive episodes can be triggered by the death of a loved one, a break-up, job loss, financial stress, a medical condition, and substance use disorder among other triggers.

“Depression affects people by changing their level of functioning in many areas of their life,” says Yoon. “Namely, people’s sleep, appetite, concentration, mood, energy level, physical health, and social lives can change dramatically due to the symptoms of depression. Often people who struggle with depression will describe having difficulty getting out of bed, having little to no motivation or energy to do the things they typically do, and feeling irritable or very sad. All of these different things certainly make living life much harder.”

Postpartum depression is depression suffered by a mother who has recently undergone childbirth, typically occurring within three months to a year after giving birth. This may be due to hormonal changes, changes in lifestyle, and parenthood fatigue.

About 70% to 80% of women will experience the “baby blues” characterized by negative feelings or mood swings after childbirth. (American Pregnancy Association, 2015)
