Depression ranges in seriousness from mild, temporary episodes of sadness to severe, persistent depression. Clinical depression is the more severe form of depression, also known as major depression or major depressive disorder. It isn't the same as depression caused by a loss, such as the death of a loved one, or a medical condition, such as a thyroid disorder.
To be diagnosed with clinical depression, you must meet the symptom criteria for major depressive disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association. This manual is used by mental health providers to diagnose mental conditions and by insurance companies to reimburse for treatment.
For clinical depression, you must have five or more of the following symptoms over a two-week period, most of the day, nearly every day. At least one of the symptoms must be either a depressed mood or a loss of interest or pleasure. Signs and symptoms may include:
Your symptoms must be severe enough to cause noticeable problems in relationships with others or in day-to-day activities, such as work, school or social activities. Symptoms may be based on your own feelings or on the observations of someone else.
Clinical depression can affect people of any age, including children. However, clinical depression symptoms, even if severe, usually improve with psychological counseling, antidepressant medications or a combination of the two.
