The American Psychiatric Association (APA) publishes the Diagnostic and Statistical Manual of Mental Disorders (DSM). The DSM-5 lists the core criteria for major depressive disorder, also referred to as clinical depression. Two new conditions added to the DSM-5’s chapter on depression are Disruptive Mood Dysregulation and Premenstrual Dysphoric Disorder. Additionally, bereavement, or grief over the loss of a loved one, is no longer excluded as a depressive disorder in the DSM-5. The DSM-IV specifier “with atypical features” can be used to characterize the current or most recent depressive episode in patients with either unipolar or bipolar type mood disorder and in patients with dysthymic disorder.10 As described in the Table, the DSM-IV specifier requires the presence of mood reactivity (criterion A) and at least 2 of 4 criterion B features (significant weight gain or hyperphagia, hypersomnia, leaden paralysis, and interpersonal rejection sensitivity resulting in social or occupational impairment). Interpersonal rejection sensitivity in the context of atypical depression implies a lifelong trait (during both periods of depression and periods of euthymia) that is typically exacerbated during depressive episodes. The validity of mood reactivity as a mandatory feature for diagnosing atypical depression has been challenged.


The hypothesis that reactive mood as a mandatory criterion is not indispensable for the diagnosis of atypical depression was supported by the community study by Angst and colleagues.21 Although mood reactivity was the most common symptom reported by their sample of patients with atypical depression (89% to 90%), other symptoms (ie, rejection sensitivity, leaden paralysis, and hypersomnia) were also quite commonly present (78% to 89%). Clearly, the inclusion of mood reactivity as a mandatory or hierarchical criterion for the diagnosis of atypical depression should be reassessed. However, there were a few notable changes from the DSM-IV to the DSM-5 in the chapter on depression. Findings from 4 studies showed that mood reactivity does not significantly correlate with the presence of criterion B features, which suggests that mood reactivity should not be considered an obligatory feature for the diagnosis of atypical depression.22,28,30,31 Furthermore, regarding melancholia (which requires the loss of mood reactivity) as exclusionary of the diagnosis of atypical depression subtype makes the presence of reactive mood largely redundant.
The correlation between the presence or absence of reactive mood and a differential response to either TCAs or MAOIs has been challenged by a number of pharmacological studies.29,32-38 Findings from those studies suggest that the effectiveness of MAOIs in depression is not necessarily associated with mood reactivity, implying that the presence of this specific feature may not be essential for diagnosing this syndrome. This suggests that atypical depression could also be effectively diagnosed when mood reactivity is not considered a mandatory criterion.21 In a more recent analysis, Angst and colleagues24 reported that diagnosis of atypical depression could be made with equal validity if 3 of 5 criteria (including mood reactivity) or 2 of 4 criteria (excluding mood reactivity) were used. This could be done using the available literature or, ideally, through more specific studies (ie, compare subjects with 2 or more criterion B symptoms and reactive mood with subjects with 2 or more criterion B symptoms without reactive mood).


Dysthymia has been replaced by a condition called Persistent Depressive Disorder, which includes the categories of Dysthymia and Major Depressive Disorder within the diagnosis. The inclusion of mood reactivity as an essential feature also neglects the fact that some depressive episodes, when quite severe, manifest with a nonreactive mood, even in the presence of reversed neurovegetative symptoms. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) defines a major depressive episode as depressed mood or loss of interest for most of the day, every day, for the past two weeks. Identifying different types of depressionThe manifestations of depression differ between patients. Some, such as adjustment disorder with depressed mood and schizoaffective depressive type, are found elsewhere in the DSM-IV.
