Delusional Misidentification of the Mirror Image

Area of Science:

• Neuroscience
• Psychiatry
• Psychology

Background:

• Delusional misidentification syndromes (DMS) involve false beliefs about identity in psychiatric or neurological disorders.
• A specific DMS presents as the delusion that one's mirror image is a separate individual.
• This phenomenon offers insights into neuropathologies of the self (NPS).

Purpose of the Study:

• To review and characterize the psychiatric, neuropathological, and neuropsychological aspects of DMS for the mirror image.
• To highlight the subjective experience of affected individuals through case presentations.
• To explore the impact of mirror DMS on the sense of self.

Main Methods:

• Review of reported cases of DMS involving mirror image misidentification.
• Analysis of psychiatric, neuropathological, and neuropsychological data.
• Inclusion of individual case presentations for subjective experience.

Main Results:

• Mirror DMS is a persistent delusion associated with neurological illness.
• The syndrome is linked to right hemisphere impairment.
• Neuropsychological and neuroimaging abnormalities are frequently observed.

Conclusions:

• DMS for the mirror image is a neurobehavioral syndrome with neurological, neuropsychological, and psychiatric dimensions.
• The inability to recognize oneself in the mirror affects the sense of self.
• Understanding mirror DMS enhances knowledge of NPS.
