Abstract: Developmental dyslexia is typically associated with major difficulties in tasks of phonological awareness, which require to identify and voluntarily manipulate the sounds of words. We report the case of a young adult suffering from disabling sequellae of severe childhood dyslexia, in whom extensive neurospychological assessment as well as brain imaging using Positron Emission Tomography (PET) provide converging evidence suggesting an aberrant utilization of visual-orthographic procedures to solve such purely phonological tasks given in the auditory modality. These observations suggest new insights into the anatomofunctional organization of the dyslexic brain.
