Atypical depression: retrospective self-reporting of treatment effectiveness

ACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2009
G. Parker
Objective:, Earlier studies demonstrated that those with atypical depression show a differentially superior response to monoamine oxidase inhibitor (MAOI) antidepressants. This study compares ratings of effectiveness for a range of treatments, amongst depressed subjects with and without atypical features. Method:, In an on-line survey, individuals experiencing likely clinical depression rated symptoms experienced when depressed, including ,atypical features' and the effectiveness of previous treatments. Mean treatment effectiveness ratings were compared amongst those with ,atypical depression' (n = 338) and ,non-atypical depression' (n = 377). Results:, There were few significant differences between the ,atypical depression' and ,non-atypical depression' groups in effectiveness ratings for drug treatments, and none for psychological treatments. The ,atypical depression' group had significantly lower mean effectiveness ratings for some selective serotonin reuptake inhibitor antidepressants. Few respondents had trialed MAOIs. Conclusion:, While MAOIs are rarely prescribed, a range of non-MAOI drug and psychological treatments are of some perceived benefit for depressed patients with atypical features. [source]

Testing atypical depression definitions

INTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 2 2005

Abstract The evidence supporting the DSM-IV definition of atypical depression (AD) is weak. This study aimed to test different definitions of AD. Major depressive disorder (MDD) patients (N = 254) and bipolar-II (BP-II) outpatients (N = 348) were interviewed consecutively, during major depressive episodes, with the Structured Clinical Interview for DSM-IV. DSM-IV criteria for AD were followed. AD validators were female gender, young onset, BP-II, axis I comorbidity, bipolar family history. Frequency of DSM-IV AD was 43.0%. AD, versus non-AD, was significantly associated with all AD validators, apart from comorbidity when controlling for age and sex. Factor analysis of atypical symptoms found factor 1 including oversleeping, overeating and weight gain (leaden paralysis at trend correlation), and factor 2 including interpersonal sensitivity, mood reactivity, and leaden paralysis. Multiple logistic regression of factor 1 versus AD validators found significant associations with several validators (including bipolar family history), whereas factor 2 had no significant associations. Findings may support a new definition of AD based on the state-dependent features oversleeping and overeating (plus perhaps leaden paralysis) versus the current AD definition based on a combination of state and trait features. Pharmacological studies are required to support any new definition of AD, as the current concept of AD is based on different response to TCA antidepressants versus non-AD.

Intra-episode hypomanic symptoms during major depression and their correlates

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 3 2004

Abstract Recent studies have shown that 40,50% of major depressive disorders (MDD) may become bipolar with time. Intra-episode hypomanic symptoms in MDD may be a first step in this shift. The purpose of the present study was to find factors associated with intra-episode hypomanic symptoms in MDD. Two hundred and forty-three consecutive MDD outpatients were interviewed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV), Clinician Version (SCID-CV), as modified by Benazzi and Akiskal (J. Affect. Disord. 2003; 73: 33,38). History of hypomania and presence of hypomanic symptoms during major depressive episode (MDE) were systematically assessed. Intra-episode hypomanic symptoms were defined as an MDE combined with three or more hypomanic symptoms, following Akiskal and Benazzi (J. Affect. Disord. 2003; 73: 113,122). Major depressive disorder with intra-episode hypomanic symptoms (MDD + H) was compared to MDD without hypomanic symptoms on classic bipolar validators. It was found that MDD + H (usually irritability, distractibility, racing thoughts, psychomotor agitation, and more talkativeness) was present in 32.5% of patients. Patients with MDD + H versus MDD had significantly lower age at onset, more atypical depressions, and more bipolar family history. Recurrences were not significantly different. Multivariate logistic regression found that bipolar family history and atypical depression were significantly and independently associated with MDD + H. Findings suggest that MDD + H may be associated with a bipolar vulnerability. Duration of illness and recurrences do not seem to be important for the onset of MDD + H. Bipolar genetic vulnerability seems to be required for onset of intra-episode hypomanic symptoms in MDD. Intra-episode hypomanic symptoms might be the first step of a process leading to the switch of MDD to bipolar disorders. Predicting the switch might have important treatment implications, because antidepressants used alone may worsen the course of bipolar disorders. Prospective studies are required to support these findings and hypotheses. [source]
