[Prognosis in severe dyslexia].
37 children with a mean reading retardation of 4,3 years were placed full time in a specialized centre. All had failed in school in spite of remedial training and/or psychotherapy. The goal of the centre is to separate linguistic and non-linguistic subjects. The non-linguistic subjects were taught with the aid of audio-visual methods in order to relieve the dyslexics of the burden of written language. If progress with reading and spelling was slow, audio-visual instruction enabled these children to reach or exceed 5th grade level in non-linguistic subjects. 80% of them were able to go on to vocational schools. At the same time, there was a very favorable improvement in their behavior (P less than 0.001), which is a prerequisite in the prevention of juvenile delinquency and an essential step in social and professional integration. These favorable results emphasize the part audio-visual instruction should play in severe dyslexia.
