Delusion of misidentifications are characterized by delusional belief that familiar person, objects, or self have been replaced or transformed. There are four common types like Capgras syndrome, Fregoli syndrome, Syndrome of subjective doubles and syndrome of intermetamorphosis. Another type of delusion of misidentification is mirrored self- misidentification, where the delusional belief is that one’s reflection in the mirror is misidentified as a stranger. Mirrored-self misidentification has rarely been described in the literature. Most of the reported patients have global dementia of the Alzheimer type, making it difficult to infer the anatomical basis of this disorder. The loss of the ability to recognize oneself in the mirror is evidence of a fundamental change in the sense of self and this may cause interpersonal problems as well. Managing such cases may be difficult and challenging.
