Configural Gestalts Remain Nothing More Than the Sum of Their Parts in Visual Agnosia [PDF]

i-Perception, 2013
We report converging evidence that higher stages of the visual system are critically required for the whole to become more than the sum of its parts by studying patient DF with visual agnosia using a configural superiority paradigm.

Perception of biological motion in visual agnosia [PDF]

Frontiers in Behavioral Neuroscience, 2012
Over the past twenty-five years, visual processing has been discussed in the context of the dual stream hypothesis consisting of a ventral (‘what') and a dorsal ('where') visual information processing pathway.

Visual agnosia and prosopagnosia secondary to melanoma metástases: Case report

Dementia & Neuropsychologia, 2007
The association of visual agnosia and prosopagnosia with cerebral metastasis is very rare. The presence of symmetric and bilateral cerebral metastases of melanoma is also uncommon. We report the case of a 34 year-old man who was admitted to hospital with

Static Visual Agnosia Following Awake Resection of a Left Frontal Low-Grade Glioma: A Case Report of Ventral Stream Network Disruption (“Astatopsia”) [PDF]

Reports
Background and Clinical Significance: Visual agnosia and speech production deficits are well-described sequelae of neurosurgical interventions, but their selective dissociation remains rare.

Posterior Cortical Atrophy in the Asia‐Pacific: A Report From the PCA Asian Workgroup [PDF]

Annals of Clinical and Translational Neurology, Volume 13, Issue 10, Page 1993-2001, October 2026.
ABSTRACT Objective Posterior Cortical Atrophy (PCA) is a distinct dementia syndrome primarily affecting spatial abilities and visual processing. It is associated with degeneration in the posterior part of the brain. PCA is subclassified into PCA‐pure and PCA‐plus syndromes based on consensus criteria.

Differential affection of the visual information sub-streams in a patient with visual agnosia [PDF]

Frontiers in Psychology
IntroductionVisual agnosia is a deficit of object recognition addressed to the damage of the ventral stream (VS). The dorsal stream (DS) is usually intact in these patients, and it can be derived from well-preserved reaching and grasping of visually ...

Selective impairment in musical chord Reading in posterior cortical atrophy: A case study of integrative visual agnosia [PDF]

Journal of Alzheimer's Disease Reports
Background Posterior cortical atrophy (PCA) is a rare neurodegenerative disorder characterized by visuospatial and/or visuoperceptual deficits, resulting from atrophy in the occipitoparietal and/or occipitotemporal cortices.

Making Memories: The Development of Long-Term Visual Knowledge in Children with Visual Agnosia [PDF]

Neural Plasticity, 2013
There are few reports about the effects of perinatal acquired brain lesions on the development of visual perception. These studies demonstrate nonseverely impaired visual-spatial abilities and preserved visual memory.

Hyperglycemic Hyperosmolar Syndrome With Higher Brain Dysfunction in Which Arterial Spin Labeling Revealed Abnormal Cerebral Blood Flow: A Case Report [PDF]

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Treatment for hyperglycemic hyperosmolar syndrome (HHS) was initiated for a transferred unconscious patient. Aphasia and agnosia remained even after metabolic improvement. Arterial spin labeling (ASL) indicated increased blood flow in the left temporal and parietal lobes.
