Reverse Intermetamorphosis Coexisting in a Case of Capgras Syndrome with Delusion of Subjective Doubles

Abstract

Delusional misidentification syndrome’ is a fascinating phenomenon in which an individual misidentifies person, place, object or even themselves and falsely believes that they have been replaced or some sort of transformation has occurred. Capgras delusion, Fregoli delusion, Intermetamorphosis, Delusion of subjective doubles, all these phenomena broadly come under the psychiatric disorder of delusional misidentification syndromes. This case was established by its clinical characteristics along with associated clinical findings, the patient’s response to treatment in concurrence with psychological and neuro-cognitive theories. The present case report suggests that these symptomatology of misperception, miscomprehension and misinterpretation of others and of self are probably more prevalent than thought previously and should be actively sought and recognised in patients. This article sought to showcase a phenomenon which had a rare component of Reverse Intermetamorphosis along with Capgras Syndrome and Delusion of Subjective Doubles having no organic component in a 22 year old male patient who responded to pharmacotherapy with neuroleptics. The psychopathological symptoms demonstrating Capgras in itself is rare and inadequately researched. Presence of three distinctive patterns of symptomatology together in one subject is intriguingly unique.
