On the behaviour of senile dementia patients vis-Ã -vis the mirror: Ajuriaguerra, Strejilevitch and Tissot (1963)

► Dementia is associated with varying degrees of impairment in using mirrors. ► Mirror agnosia is a procedural impairment and not a semantic one. ► Improvements using mirror space in mirror ataxia patients do not persist over time. ► The mirrored-self misidentification delusion requires two separate factors. ► Delusional belief, such as mirrored-self misidentification, may fluctuate over time.
