A woman with Capgras and de Clerambault's syndromes transmitted
persecutory, erotic, and somatic delusions to her son in a folie a deux.
Capgras and de Clerambault's syndromes appear together more commonly than
is apparent in the literature. Review of these cases shows a strong
association with severe affective disorder.
