10 Weirdest Delusions among People

Reduplicative Paramnesia

Next

Reduplicative paramnesia is the delusional belief that a place or location has been duplicated, existing in two or more places simultaneously, or that it has been ‘relocated’ to another site. Taken from the Benson and colleagues study, the following excerpt illustrates some of the core features of the delusion. The patient had suffered a head injury after a fall in his home. The impact had caused a fractured skull. A few days after admission to the Neurobehavioural Center, orientation for time was intact, he could give details of the accident (as related to him by others), could remember his doctors’ names and could learn new information and retain it indefinitely. He exhibited, however, a distinct abnormality of orientation for place. While he quickly learned and remembered that he was at the Jamaica Plain Veterans Hospital (also known as the Boston Veterans Administration Hospital), he insisted that the hospital was located in Taunton, Massachusetts, his home town. Under close questioning, he acknowledged that Jamaica Plain was part of Boston and admitted it would be strange for there to be two Jamaica Plain Veterans Hospitals. Nonetheless, he insisted that he was presently hospitalized in a branch of the Jamaica Plain Veterans Hospital located in Taunton. At one time he stated that the hospital was located in the spare bedroom of his house.
