ABSTRACT

Introduction. Visual agnosia is an acquired visual deficiency characterized by a difficulty in recognizing stimuli, not being attributed to a vision loss, language difficulties or general mental deterioration. The treatment for this clinical entity has focused primarily on compensatory training strategies and rarely includes neuropsychological rehabilitation. The objective of this article is to introduce the significant clinical improvement of two patients with aperceptive visual agnosia who were put through the “Modelo PAINT” neuropsychological rehabilitation method.
Cases report. The first case, YJ, is a woman who suffered a traumatic brain injury that provoked a right thalamic injury that extended towards temporo-occipital areas. In the neuropsychological evaluation she only perceived shadows and color packages without recognizing objects, letters, numbers or faces. The second case, RZ, is a man who suffered a stroke in the posterior cerebral artery territory. In the neuropsychological evaluation he had object agnosia, prosopagnosia, alexia and could perceive shadows. Both patients were submitted to a cognitive stimulating program based on the hierarchical rehabilitation of the damaged functions and reorganization of the functional system. The rehabilitation was carried out in stages whose main focus was the ordered stimulation of projection, association and integration areas. In both cases the prosopagnosia, object recognition, letter and number recognition had a successful resolution.
Conclusion. The significant clinical improvement presented by both patients suggests that therapy intervention in visual agnosia should not only be based on compensatory training strategies but must pursue the rehabilitation of decreased functions and the reorganization of the functional system.
