A few years later a Paris colleague proposed to rename the "illusion des sosies" into Capgras Syndrome.
Thus, Capgras Syndrome, as originally conceived, was a female disorder, part of the general diagnosis of hysteria.
In most cases of Capgras Syndrome the doubles are part of a system of paranoid delusions.
Until the 1980s the accepted view was that Capgras Syndrome was a psychiatric disorder.
One study found 83% paranoid delusions and 43% derealization and depersonalization in Capgras syndrome cases (7).
A study conducted in an acute psychiatric service found that the Capgras syndrome rate was 2.
In the literature, the initial studies regarding the Capgras syndrome attributed the causation psychoanalytically but subsequent authors emphasized diffuse and localized brain lesions, whereas some authors reported the association of two different causations (10).
Psychodynamic explanations of the origins of the Capgras syndrome consist of four basic groups; unresolved oedipal problems in women, alienation and other affective problems, problems related with ambivalence and pathological separation of internal object representatives (10).
Key Words: benzodiazepines, Capgras syndrome, diazepam
Capgras syndrome is an unusual syndrome in which the patient believes that one or more people have been replaced by identical-appearing doubles.
Capgras syndrome is typically seen in schizophrenia or dementia, but in this case seemed to be causally related to treatment with diazepam.
An iatrogenic etiology should be considered in the differential diagnosis of any new delusion, including Capgras syndrome.
