[The role of RDoC system in the research of mental disorders - Changing the psychiatric nosology paradigm?]

Nowadays, one of the biggest challenge of psychiatry is the renewal of classification systems. The newest version of DSM, the 5th, - even though it is based on extensive professional consensus - is criticized numerously, as it could not exceed the cathegorical and simplistic syndromathologic approach. For this reason it seems to be indispensable to implement a new diagnostic system, which includes the modern neurosience researches and the clinical observations together. The main goal in the creation of the Research Domain Criteria (RDoC) model was to implement a new research criteria system which facilitates to understand the biologic and psychosocial background of mental illnesses. In our article we present the most important characteristics of RDoC system, in particular its dimensionality, its behaviour- based and neuro-bio-social approach, futhermore its developmental perspective. The benefits of this modell's application are illustrated by the newest results of the research related to depressive disorders and suicidal behaviour.
