Capgras' delusion: an example of coalescent psychodynamic and organic factors.

The case of a 33-year-old woman with a right hemisphere lesion after subarachnoid bleed is reported. She developed the false belief that her husband, her mother, her children, and herself had been replaced by doubles after the birth of her fourth daughter. The multifactorial etiology of the Capgras delusion is discussed with a brief review of the literature.
