Impairments of auditory scene analysis in Alzheimer's disease
Parsing of sound sources in the auditory environment or 'auditory scene analysis' is a computationally demanding cognitive operation that is likely to be vulnerable to the neurodegenerative process in Alzheimer's disease. However, little information is available concerning auditory scene analysis in Alzheimer's disease. Here we undertook a detailed neuropsychological and neuroanatomical charact...
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 کاملScene perception in posterior cortical atrophy: categorization, description and fixation patterns
Partial or complete Balint's syndrome is a core feature of the clinico-radiological syndrome of posterior cortical atrophy (PCA), in which individuals experience a progressive deterioration of cortical vision. Although multi-object arrays are frequently used to detect simultanagnosia in the clinical assessment and diagnosis of PCA, to date there have been no group studies of scene perception in...
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...
