[Source-monitoring deficits in schizophrenia: review and pharmacotherapeutic implications].

The disturbance of source-monitoring is one of the various impairments in cognitive functioning observed in schizophrenic patients. The process of source-monitoring allows individuals to distinguish self generated thoughts and behaviours from those generated by others. The aim of the present study is to review the general psychological definition of source memory and source-monitoring and its neurological basis as well as the models for explanation of source-monitoring deficits. The relationship between source-monitoring-deficits and psychopathological symptoms as well as the effect of antipsychotic treatment on source-monitoring disturbances are introduced. There is evidence suggesting, that a selective source-monitoring deficit is in the occurrence of auditory hallucinations. The disturbance of prospective memory may influence unfavorably the compliance. Administration of antipsychotics in general can improve source-monitoring deficits. The neuropsychiatric perspective provides a more accurate and comprehensive understanding of schizophrenia.
