  • Abstract
  • Look Inside

 We described a 22-year-old woman who had previously been diagnosed as having major depression, bipolar disorder, schizophrenia, and epilepsy. She had a unique kind of interpretation delusion. She believed that any person, who had some resemblance to a member of her family, was a member of her family. For example, “that nurse is my sister, because her face looks like me” and “Dr. A is my brother, because I feel comfortable talking with him.” Her delusion was occasional and was not systematic. She also had other misidentification syndromes, such as MacCallum syndrome, neglect of her own belongings, and neglect of her own and other persons'voice. She had had an epileptic focus in the right parietooccipital region. She also had echolalia, delayed echolalia, disturbance of shortterm memory, and slight motor impersistence. This unique form of delusional misidentification, named “misidentification of relationship”, may be caused by synergism of psychodynamics and some neuropsychological deficit.
