Delusional misidentification involving the self.
The delusion of replacement of one's self by a double or imposter is a feature of two delusional misidentification syndromes. In the syndrome of subjective doubles, the self-delusional misidentification syndromes. In the syndrome of subjective doubles, the self-delusion is the sole delusion of doubles. In the Capgras syndrome, the delusion of a self-double is infrequently reported; however, when it is reported, self-replacement is always accompanied by delusions of duplication of other people and sometimes of places. We review all such cases reported since 1900 and highlight the variety of presentations.
