title: [Delusions: current psychodynamic and neurocognitive approaches].
abstract: BACKGROUND
  The symptom "delusions" is a central psychopathological symptom in psychiatric diseases. Since the beginning of psychiatry various disciplines have attempted to explain and understand delusions but even now no generally accepted definition of this phenomenon exists.
  
  
  OBJECTIVE
  A comprehensive review of current psychopathological and neurobiological theories of delusions is given.
  
  
  METHODS
  PubMed and Google scholar searches were performed using the keywords "delusion", "psychodynamic" and "neurobiology", both in English and German. Relevant German textbooks of psychiatry were also included.
  
  
  CONCLUSIONS
  A differentiated perspective of the phenomenon of delusions appears to be necessary to approach this complex and fascinating symptom. A one-dimensional approach does not do justice to the complexity of delusions. The various explanatory approaches can increasingly be linked to each other and are no longer considered to be mutually exclusive.
