[Posterior cortical atrophy: anatomo-clinical variant of Alzheimer's disease].

Abstract

The authors report the case of a 66-year-old woman who developed progressive occipital dysfunction and lately a dementing illness. Brain CT revealed posterior cerebral atrophy. Post-mortem examination showed the characteristic features of Alzheimer's disease, mainly in the posterior areas, relatively sparing the amygdala and Ammon's horn. The occurrence of focal signs and lesions in Alzheimer's disease is emphasized.
