Dysphoria from a transnosological perspective

The objective of our psychopathological analyses is to shed light on the position of irritable mood (dysphoria) in psychiatric diagnostics and nosology. In today's most commonly applied classification systems, the ICD-10 and the DSM-IV, dysphoria is mentioned mostly in the context of diagnostic criteria of personality and affective disorders. Other authors have emphasized the importance of dysphoric states in organic psychoses and delusional disorders. Summarizing the various publications on the nosological position, dysphoria is a nosological nonspecific syndrome which may occur in the course of all psychiatric disorders and illnesses. According to the results of our psychopathological analyses, the pathogenesis of dysphoria has to be considered as a multidimensional circular process in which various mental, physical and social factors act as predisposing, triggering and disorder-maintaining factors. Stressors induced by particular experiences and perceptions and by impaired health may lead to a dysphoric state if adequate coping mechanisms are missing. Dysphoria itself usually leads to a deterioration in the mental and physical state of the patient, and shows a clear impact on the patient's social network. The reactions of people close to the patient combined with the impaired mental and physical conditions of the patient cause the circle to restart. As contemporary diagnostic entities do not refer to pathogenesis, classical categorical diagnostics cannot provide the basis for effective pathogenesis-oriented therapy. A change of paradigm in diagnostics from a categorical to a dimensional approach thus becomes necessary. Following a dimensional diagnostic approach based on a dynamic model of vulnerability, a precise differential diagnosis of the complex constellation of conditions and their interactions becomes necessary in order to develop effective treatment strategies. Disorder-maintaining factors determine the treatment of the acute symptomatology, whereas predisposing and triggering factors serve as the basis for the prophylactic treatment.
