title: [Recommendations regarding diagnosis and treatment of obsessive-compulsive symptoms in schizophrenia].
abstract: BACKGROUND
  Obsessive-compulsive symptoms (OCS) are common in patients with schizophrenia. Although these symptoms are associated with an unfavourable course of the illness, in many cases they are not recognised or treated. The situation for patients with schizophrenia and obsessive-compulsive disorder (OCD) could improve considerably now that more advanced diagnostic techniques and better treatment options have been available.
  
  
  OBJECTIVE
  To provide an overview of current knowledge regarding diagnosis and treatment options.
  
  
  METHODS
  We searched the literature for relevant articles.
  
  
  RESULTS
  With careful diagnosis OCS could be better noticed. Based on the time of onset of the OCS and the relationship between these symptoms and the use of antipsychotics, we propose a treatment strategy.
  
  
  CONCLUSIONS
  Cognitive behavioural therapy, as well as various pharmacotherapeutic strategies, are promising treatment options that could deployed more frequently to treat persistent OCD in schizophrenia. Although the research findings are homogeneous, the methodological quality of the studies is still low.
