Capgras syndrome
Last reviewed 01/2018
In the Capgras syndrome the patient is deluded that a person closely related to him has been replaced by an identical double.
This is an extremely rare condition and is usually associated with schizophrenia or affective disorder.
Occasional cases of Capgras syndrome are seen following brain injury (usually in the temporal area) or cerebral atrophy.
This condition may be rarely associated with a pituitary tumour.
