Troubles visuo-constructifs et méthodes de compensation: Résultats de 85 patients atteints de lésions cérébrales

Abstract

The results of this work suggest a contrast between two types of visuo-constructive deficit: the first, which is caused by parieto-occipital lesions, is very specific and is compensated for by the presence of visual cues, whether the lesion be in the right or left hemisphere; the second, compensated for by a program of action, and associated with global behavioural inertia and perseverations, is however specific to frontal lesions. They are in favour of the hypothesis of LURIA and TSVETKOVA which proposes: in the case of parieto-occipital lesions the basic factor on which the visuo-constructive problems depend is a loss of spatial organisation of elements; in the case of frontal lesions the basic factor would be a loss of programming and the regulation of sequential behaviour.
