Posterior cortical atrophy as a variant of progressive local brain atrophy

Abstract

Posterior cortical atrophy (PCA) is a rare disease that manifestsmainly as disturbance of cortical visual function, agnosia.Blints syndrome (optic ataxia) is one of the clearest clinicalmarkers of the disease. The disease is caused by progressive atrophyof the visual cortex. Many researchers define PCA as anindependent disease, while others suggest that it is a posteriorvariant of Alzheimers disease, corticobasal degeneration, etc. Morphological studies of brain tissues support the neurodegenerativenature of the disease.
