Abstract:
Posterior cortical atrophy (PCA) is a kind of neurodegenerative dementia,which is characterized by the progressive decline of visuoperceptual,visuospatial,reading and writing ability and praxic skills.Neuroimaging usually shows atrophy or metabolic decrease in posterior brain regions.The most common neuropathologic changes of PCA are amyloid plaques deposition and neurofibrillary tangles in posterior cortex.In general,PCA is considered as a variant form of Alzheimer's disease.
