A variety of negative results after RCTs of SSRIs in the treatment and prophylaxis of RBD have been published (eg, Montgomery et al77 and Angst et al78), but it was hypothesized that methodological problems and highly selected patient samples have been responsible for for these results.76 Efficacious treatment algorithms for RBD have not been established yet.79 Seasonal Inhibitors,research,lifescience,medical affective disorder Patients suffering from depression recurring on a regular ref 3 annual basis during fall or early winter and spring often show subsequent symptoms of bipolar disorder. In addition, depressive syndromes often are characterized by features listed as atypical in DSM-IV-TR. If depressive symptoms arc of

moderate severity, seasonal forms of depression are Inhibitors,research,lifescience,medical treated like other recurrent episodes. exactly bright-light therapy (phototherapy) can be used as an early augmentation strategy. Because of the proven efficacy,80, 81 bright-light therapy can even be used as a monotherapy in case of mild depression during a limited

treatment trial, but the possibility of occurrence or enhancement of suicidal ideations during phototherapy has to be taken into account.82 Inhibitors,research,lifescience,medical Other features of MDD influencing course and treatment outcome Atypical depression There is no clear agreement about the features that should characterize atypical depression.83 In Frenchspeaking countries the term “atypical” depression is used for a group of patients with psychotic features. According to DSM-IV-TR in atypical depression at least two of the criteria summarized in Table IV should be present. Nevertheless, Inhibitors,research,lifescience,medical it was postulated that applying DSM-IVTR criteria for atypical depression represents a valid diagnosis distinct from other forms of depression, but includes a very heterogeneous patient population.16 Also the Inventory of Depressive Symptomatology-Clinician Rating (IDS-C30) is suitable for the diagnosis of atypical depression including an earlier age at onset, a greater comorbidity with anxiety symptoms, and greater symptom severity compared with nonatypical depression.81 An epidemiological

Inhibitors,research,lifescience,medical study in primary care found a considerably high proportion of depressed patients suffering from atypical features, suggesting that atypical depression which may contribute to under-recognition of depression in primary care.85 Dacomitinib Patients suffering from atypical depression may have an overall earlier age of onset and a more chronic course of illness in comparison with patients suffering from depression with melancholic features.16 Nevertheless, those patient groups are also characterized by a high longitudinal association, ie, an overlap of symptoms during the time course of depression: transitions from atypical to melancholic and to nonmelancholic types of depression are described.86 Empirical data support the hypothesis that MAOIs and SSRIs represent a first-line treatment option which is superior to other pharmacological treatments.
