The cognitive profile of posterior cortical atrophy.
BACKGROUND Posterior cortical atrophy (PCA) is a progressive dementia characterized by prominent disorders of higher visual processing, affecting both dorsal and ventral streams to cause Balint's syndrome, alexia, and visual agnosia. OBJECTIVE To define the cognitive profile of PCA and compare to the typical, primary amnestic dementia of the Alzheimer's type (DAT). METHODS The authors used ...
متن کاملPosterior 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 کاملNeural correlates of cognitive impairment in posterior cortical atrophy.
With the prospect of disease-modifying drugs that will target the physiopathological process of Alzheimer's disease, it is now crucial to increase the understanding of the atypical focal presentations of Alzheimer's disease, such as posterior cortical atrophy. This study aimed to (i) characterize the brain perfusion profile in posterior cortical atrophy using regions of interest and a voxel-bas...
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...
