Inability to Recognize One's Own Reflection in Alzheimer Disease

A 77-year-old retired primary school teacher with probable Alzheimer dementia diagnosed after 2 years of progressive short-term memory loss and predominant hippocampal atrophy on magnetic resonance imaging of the brain became frequently puzzled and astonished by his reflection in the mirror, as shown in this video. He was able to recognize others in the same reflection (see    • Alzheimer Disease and Ability to Reco...  ).

Mirrored-self misidentification is associated with failure of face-selective activity in the right occipitotemporal cortex, probably causing impaired mapping of the perceived face on stored memory representations.
