What Is Major or Clinical Depression?
Most people feel sad or low at some point in their lives. But clinical depression is marked by a depressed mood most of the day, particularly in the morning, and a loss of interest in normal activities and relationships -- symptoms that are present every day for at least 2 weeks. In addition, according to the DSM-5 -- a manual used to diagnose mental health conditions -- you may have other symptoms with major depression. Those symptoms might include:
Major depression affects about 6.7% of the U.S. population over age 18, according to the National Institute of Mental Health. Overall, between 20% and 25% of adults may suffer an episode of major depression at some point during their lifetime.
Major depression also affects older adults, teens, and children, but frequently goes undiagnosed and untreated in these populations.
Other factors that boost the risk of clinical depression in women who are biologically vulnerable to it include increased stress at home or at work, balancing family life with career, and caring for an aging parent. Raising a child alone will also increase the risk.
