Posterior cortical atrophy
Posterior cortical atrophy (PCA) is a neurodegenerative syndrome that is characterised by progressive decline in visuospatial, visuoperceptual, literacy, and praxic skills. The progressive neurodegeneration affecting parietal, occipital, and occipitotemporal cortices that underlies PCA is attributable to Alzheimer's disease in most patients. However, alternative underlying causes, including dem...

متن کاملShining a light on posterior cortical atrophy.
Posterior cortical atrophy (PCA) is a clinicoradiologic syndrome characterized by progressive decline in visual processing skills, relatively intact memory and language in the early stages, and atrophy of posterior brain regions. Misdiagnosis of PCA is common, owing not only to its relative rarity and unusual and variable presentation, but also because patients frequently first seek the opinion...
متن کاملVisual hallucinations in posterior cortical atrophy.
BACKGROUND Visual hallucinations have been reported to occur in up to 25% of patients who meet the criteria for posterior cortical atrophy (PCA). It is not known, however, whether patients who meet the criteria for PCA and have hallucinations are different from those who meet the criteria and do not have hallucinations. OBJECTIVE To compare the clinical and imaging features of patients with P...
متن کاملOlfactory impairment in posterior cortical atrophy
INTRODUCTION Olfactory dysfunction develops in many neurodegenerative diseases, and is an early feature of the most common neurodegen-erative disorder, Alzheimer's disease (AD). 1–5 Anatomically, the central olfactory pathways traverse brain regions implicated in the common neurodegenerative diseases, including the mesial temporal and inferior frontal lobes. 6–10 Phenotypically, AD shows substa...
