Study Overview
Brief Summary
Dyslexia is first described as a phonological deficit. Several studies report a neurovisual deficit in dyslexics. Some dyslexics have a visual deficit without phonological impairment, others have a pure phonological deficit, and still others have both types of deficits. From this observation the idea emerged to propose specific remediation protocols for people with visual impairments and to assess their effects on reading. At the theoretical level, if visual stimulation is able to improve reading performance, it is the demonstration of the existence of visual origin of dyslexia. At the clinical level, such a result not only opens the prospect of a different and more adapted rehabilitation for these types of dyslexia, but also the prospect, if the visual deficits are pre-existing to the learning of reading, to use them for early diagnosis and management.
