Reduplicative paramnesia is a condition in which one believes that a place has been duplicated and exists simultaneously in more than one location or that it has been relocated to another site. It is one of the delusional misidentification syndromes, which involve a belief that the identity of a person, object, or place has somehow changed. Highly rare, it is most often observed in brain injury patients who are otherwise logically sound. When was it first observed? Discuss
