Abstract

Posterior cortical atrophy (PCA) is a subgroup of focal cortical atrophy with progressive degenerative dementia that begins with higher visual dysfunction. We present two patients with symptoms suggestive of PCA. They have mild memory impairment early in the course of disease and intact primary motor and sensory modalities. Parieto-occipital atrophy was evident on brain MRI in one patient and the other was suspicious. We think that these findings are consistent with posterior cortical atrophy which is variant of Alzheimer's disease.Key Words: Posterior cortical atrophy, Balint's syndrome, Alzheimer's disease
