What is reduplicative paramnesia

When we talk about reduplicative paramnesia, we are referring to a mental disorder of perception in which beliefs have as their main idea that a place has been copied or built in another space at the same time. In other words, the person who suffers from this clinical condition has the conviction that the same site exists in two or more different places, or that a certain site has been moved to another place. This set of thoughts is part of neurological disorders framed in delusional false identification syndromes.

Symptoms of reduplicative paramnesia

There are some manifestations that must be taken into account when detecting this disorder. Next, we will mention the main symptoms of reduplicative paramnesia:

  • Delusion regarding the identity or uniqueness of a person: The person firmly believes in what he sees or perceives despite the fact that there are facts that contrast it. For example, someone may believe that the same person is in two places with a great distance between them in Spain despite having seen them only once or that they have been duplicated. This is called reduplicative false identification.
  • Certainty regarding the location of a site and/or a person: The patient who suffers from reduplicative paramnesia does not doubt that the same person or the same place has been duplicated or copied, but rather has an absolute conviction about these facts. This is not a question of fantasy but of absolute security.
