Mirrored self-misidentification



Mirrored self-misidentification is the delusional belief that one's reflection in a mirror is some other person (often believed to be someone who is following them around). Often people who suffer from this delusion are not delusional about anything else. It is considered to be a monothematic delusion and sometimes also labeled as a delusional misidentification syndrome. This disorder is often found within the context of dementia and can also be caused by the organic disfunction resulting from traumatic brain injury, stroke, or neurological illness.

Additional recommended knowledge

As a disease, this rare behavior cannot be diagnosed in a kind of animal which does not normally understand the nature of a mirror.

Causes

Like other monothematic delusions, mirrored self-misidentification is currently thought to be initially caused by a neurological defect, typically in the right hemisphere, which affects one's experience. Current research points toward two potential disfunctions that may lead to this disorder:

  • Patients who have impaired face perception and thus can no longer recognize themselves (similar to Capgras delusion)
  • Patients who have lost the ability to interact appropriately with mirrors.
