Anosognosia in Alzheimer's disease--the petrified self.
This paper reviews the literature concerning the neural correlates of the self, the relationship between self and memory and the profile of memory impairments in Alzheimer's disease (AD) and explores the relationship between the preservation of the self and anosognosia in this condition. It concludes that a potential explanation for anosognosia in AD is a lack of updating of personal information due to the memory impairments characteristic of this disease. We put forward the hypothesis that anosognosia is due in part to the "petrified self."
