Definition:
Although it's not a formally recognized term, clinical depression describes a condition in which persistent low mood and related symptoms are severe enough to interfere with everyday life. Losing interest in activities, having trouble finding pleasure in things that you used to enjoy, deep sadness, and unexplained crying are just some of the possible symptoms of clinical depression. The word "clinical" implies that the symptoms are serious enough to require psychiatric treatment.

Also Known As: Major Depression, major depressive episode
