Une nouvelle observation d'agnosie d'objet. deficit de l'association ou de la categorisation, specifique de la modalite visuelle?

Abstract

This is the report of a case of visual object agnosia, associated with pure alexia and colour agnosia but with no impairment on recognition of shapes, faces, or spatial data. The subject showed no sign of general intellectual deterioration, his speech was unimpaired and his visual acuity excellent. The symptom appeared following a large occipital left lobectomy. The results on a series of tests lead the authors to conclude that this visual agnosia is of associative type but that the basic disorder represents a specific categorisation deficit for visual inputs.
