Memory Impairment at Initial Clinical Presentation in Posterior Cortical Atrophy.
Posterior cortical atrophy (PCA) is characterized by core visuospatial and visuoperceptual deficits, and predominant atrophy in the parieto-occipital cortex. The most common underlying pathology is Alzheimer's disease (AD). Existing diagnostic criteria suggest that episodic memory is relatively preserved. The aim of this study was to examine memory performance at initial clinical presentation i...
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...
متن کاملVisual Dysfunction in Posterior Cortical Atrophy
Posterior cortical atrophy (PCA) is a syndromic diagnosis. It is characterized by progressive impairment of higher (cortical) visual function with imaging evidence of degeneration affecting the occipital, parietal, and posterior temporal lobes bilaterally. Most cases will prove to have Alzheimer pathology. The aim of this review is to summarize the development of the concept of this disorder si...
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...
