Capgras syndrome (CS) is a rare type of schizophrenia characterized by delusions that the patient is often replaced by their parents, relatives and sometimes even their identical twins. It is very rare in childhood. It has been reported that Capgras syndrome is frequently seen in schizophrenic cases, especially in paranoid schiphrenia and it can be observed in depression an mania. Although there is no single reason, biological and psychological factors are thought to play a role in its atiopathogenesis. While psychodynamic explanations were brought to the syndrome in may cases related to pscyhological factors, biological factors were reported to have widespread and localized brain lesions.
