Intermetamorphosis syndrome is a variant of Capgras’ delusion, where one believes that someone has transformed physically and psychologically into another person (Bick, 1984). Intermetamorphosis syndrome is often comorbid with psychiatric and neurological disorders, such as Schizophrenia and dementia (Cipriani et al., 2013; Forstl, Almeida, Owen, Burns, & Howard, 1991).
