| ==Overview==
| |
| [[Major depressive disorder]] a [[psychiatric disorder]] characterized by a pervasive low [[mood]], loss of interest in usual activities, and a diminished ability to experience pleasure ([[anhedonia]]).
| |
|
| |
| Although the term "depression" is commonly used to describe a temporary [[depression (mood)|depressed mood]] (i.e., "feeling blue"), [[major depressive disorder]] is a serious and often disabling condition that can significantly affect a person's work, family, and school life; sleeping and eating habits; general health; and ability to enjoy life.<ref name="NIMHPub">{{cite web

[[Major depressive disorder]] is a major risk factor for [[suicide]]. In addition, people with depression suffer from higher [[mortality]] from other causes.<ref name="pmid17640152">{{cite journal |author=Rush AJ |title=The varied clinical presentations of major depressive disorder |journal=The Journal of clinical psychiatry |volume=68 Suppl 8 |issue= |pages=4–10 |year=2007 |pmid=17640152 |doi=}}</ref>

| When specific treatment is indicated, it usually consists of [[psychotherapy]] and [[antidepressant]]s.

| ==Diagnosis==
| |
|
| |
| ===History and Symptoms===
| |
|
| |
| Before a diagnosis of depression can be made, a [[physician]] should perform a complete medical exam to rule out any possible physical cause for the suspected depression. If no such cause is found, a psychological evaluation should be done by the physician or by referral to a [[psychiatrist]]or [[psychologist]]. The evaluation will include a complete history of symptoms, a discussion of alcohol and drug use, and whether the patient has had or is having suicidal thoughts or thinking about [[death]]. The evaluation will also include a family medical history to see if other family members suffer from any form of depression or similar mood disorder.

| |
| ===Medical Therapy===
| |
|
| |
| The treatment of depression is highly individualized to the patient, based on the patient's unique combination of biological, psychological and social health factors and the severity of their condition.<ref name="MayoGuide">{{cite web

New treatments and less conventional options are also available, including self help, life style changes, and vagus nerve stimulation.<ref name="MayoGuide" /> If there is an imminent threat of [[suicide]] or the patient is a danger to others, hospitalization is employed as an intervention method to keep at-risk individuals safe until they cease to be a danger to themselves or others. At-risk individuals may also be placed in a [[partial hospitalization]] therapy, in which the patient sleeps at home but spends most of the day in a psychiatric hospital setting. This intensive treatment usually involves [[group therapy]], [[psychotherapy|individual therapy]], [[psychopharmacology|medication management]], and is used often in the case of children and adolescents.
