A case of "subjective" Frégoli syndrome.

In the classic type of Frégoli syndrome, the affected person believes that another person's mind can inhibit the body of another person. We present an unusual presentation of Frégoli syndrome in which a patient believed that copies of his own mind inhabited the bodies of others. Given that the misidentification syndrome called subjective doubles involves the delusional belief that one's own physical double exists, by analogy this patient suffered from "subjective" Frégoli syndrome.
