[The Capgras syndrome].

A new case of Capgras' syndrome is presented with a short review on the subject. Since there are many controversies about the etiology of this syndrome, and since some authors explain it with organic factors, others with psychodynamic factors, or a combination of the two, one should be careful with this syndrome to eliminate the presence of organic factors with a meticulous physical examination and appropriate neuropsychological tests. A thorough examination of early interpersonal relations is necessary to verify psychodynamic hypothesis, the most plausible being the splitting of internalized object representations.
