- mirrored self-misidentification
- A term that refers to a misidentification syndrome in which the affected individual is unable to identify his or her mirror image as oneself. The concomitant staring behaviour in front of a mirror or other reflecting surface is referred to as the * mirror sign. Theoretically, mirrored self-misidentification may be at once delusional and illusory in nature. For example, individuals with a clinical diagnosis of Alzheimer's disease may attempt to converse with their mirror image and ask why that person is being held prisoner or become annoyed at the idea of being followed by the person they perceive in the mirror. A related - but extremely rare - phenomenon is *negative autoscopy, characterized by the failure to perceive one's mirror image while looking into a mirror.ReferencesDening, T.R., Berrios, G.E.
