Abstract
This investigation was made on 1,278 school-children, since 1958. The evolution of these children was controlled periodically. In order to comprehend the fine dysphasic symptomatology that we have found in this research, we shall remember previously some notions about „infantile aphasia” and about the scope of the expression: „dysphasia in school-children”. Then we shall see the general statement of the study followed in three schools and finally the general diagnoses obtained and some dysphasic symptomes of neurological importance.
