Schizophrenia is the most common cause of Folie à trios. We intend to report a case of Folie à trios (three members of the same family) and delusional disorder by proxy in a family who were referred to psychiatrist.
This report presents a 50-year-old female with congenital blindness plus her daughters were hospitalized in psychiatric service. The woman shared persecutory, poisoning and being control delusion with her 23 and 17-year-old daughters and then they were isolated because their delusions. They responded to treatment follow electroconvulsive therapy.
We suggest that Folie à trios can induced by patients with sensory deficits and low educated.
