This video answers the question: What is meant by the term high functioning depression? High functioning depression is not a mental disorder, but is a term used in popular culture to describe the symptoms of depression that have a minimal effect on functioning at work, at school or in social activities. It is analogous to an old mental disorder called dysthymia or dysthymic disorder, which referred to a series of depressive symptoms that were low grade and tended to last for several years. To better understand the construct, it is important to understand major depressive disorder and a disorder called persistent depressive disorder. Major depressive disorder is a chronic disorder and symptoms must be present for at least two weeks for a diagnosis. There is a list of symptoms in the criteria of symptoms in the Diagnostic and Statistical Manual and here we see that five or more symptoms should be supported. One of these symptoms should be a depressed mood or less interest or pleasure in activities. We also see other symptoms associated with the disorder that include a change in weight or a change in appetite, sleep disturbances, psychomotor agitation, fatigue or loss of energy, feelings of worthlessness or inappropriate guilt, difficulty concentrating and suicidal ideas. When these symptoms occur and some other different criteria are met, someone may have a major depressive disorder. Persistent depressive disorder has a depressed mood and symptoms must be present for at least two years. In addition to depressed mood, two or more symptoms of symptom criteria must be met and we see symptoms such as lack of appetite, sleep disturbances, fatigue, decreased self-esteem, difficulty concentrating and hopelessness. We see that there is some overlap between the criteria of symptoms for PDD and MDD, but the overlap is not perfect.
