Depressive disorder or Depression
Epidemiology of Depressive disorder
Community studies generally show a high prevalence of depression in different countries. Estimations of the so called point prevalence (the number of people meeting criteria of the disorder at a certain moment in time) vary between 5 and 7.5%. The one-year prevalence of major depressive disorder in the United States varies from 3% in the Epidemiological Catchment Area Study[1] to 10% in the National Co-morbity Study.[2]
Diagnostic criteria
Note: The American Psychiatric Association, which publishes the Diagnostic and Statistical Manual of Mental Disorders, forbids the unauthorized reproduction of their diagnostic criteria. A narrative of the DSM-IV-TR criteria follows. The core symptoms of depression are depressed mood and a lack of interest or pleasure from daily activities (anhedonia). Several additional features may be present, like lack of concentration, inappropriate guilt feelings, suicidal thoughts, psychomotor retardation or agitation and loss of libido. A diurnal variation, e.g. the symptoms are worse in the morning, may be present.
Treatment
Approximately 30% of patients have remission of depression with medications.[3] For patients with inadequate response, either adding sustained-release bupropion (initially 200 mg per day then increase by 100 mg up to total of 400 mg per day) or buspirone (up to 60 mg per day) for augmentation as a second drug can cause remission in approximately 30% of patients[4], while switching medications can achieve remission in about 25% of patients[5].
