Object recognition and visual object agnosia.

Handb Clin Neurol 2021 ;178:155-173

Department of Psychology, University of Copenhagen, Copenhagen, Denmark.

The term visual agnosia is used to refer to recognition disorders that are confined to the visual modality, that are not due to an impairment in sensory functions, and that cannot be explained by other cognitive deficits or by general reduction in intellectual ability. Here, we describe the different types of visual agnosia that have been reported (form agnosia, integrative agnosia, associative agnosia, transformational and orientation agnosia as well as category-specific impairments such as pure alexia and prosopagnosia) and how they relate to the current understanding of visual object recognition. Together with related disorders such as simultanagnosia, texture agnosia, aphantasia, and optic aphasia, these visual perceptual impairments can have severe consequences for those affected.

Visual form-processing deficits: a global clinical classification.

Neurologia 2014 Oct 30;29(8):482-9. Epub 2012 May 30.

Servicio de Neurología, Hospital Universitario de Salamanca, Salamanca, España.

Introduction: Patients who have difficulties recognising visual form stimuli are usually labelled as having visual agnosia. However, recent studies let us identify different clinical manifestations corresponding to discrete diagnostic entities which reflect a variety of deficits along the continuum of cortical visual processing.

Development: We reviewed different clinical cases published in medical literature as well as proposals for classifying deficits in order to provide a global perspective of the subject. Read More
