The article describes a case study of visual agnosia in which neuropsychological assessment was carried out on a 70-year-old woman В. She cannot recognize familiar faces and even her own. She exhibits a sheer case of topographical agnosia being unable to recognize familiar surroundings. Although she passed standard color tests she fails to recognize color pictures and to name colors. She has problems with recognizing letters despite retaining writing skills. These deficiencies have been caused by the bilateral lesions of the inferior areas of the temporal-parietal-occipital lobes.

The article presents the results of a case study of visual agnosia. A rare case of multiple visual agnosia (object agnosia, prosopagnosia, dyslexia, color agonsia) of a patient with the bilateral damage of the brain is described. A set of various methods has been developed to diagnose the variety of cognitive disorders. A neuropsychological approach has been used to qualitatively analyze errors. Some particular features of visual cognitive disorder are considered from the point of view of the dynamic complementary interaction between the brain hemispheres and their functional asymmetry.
