Written language disorders
Dyslexia can be defined as serious and lasting troubles in acquiring written language in normally intelligent children presenting no sensorial troubles or serious affective disorders.
Multiple cognitive troubles could cause dyslexia. A ‘simple’ delay in learning can be wrongly confused with dyslexia.

- Unintelligible writing in its form (graphic, spelling and word segmentation) and content, organisational difficulties, need for landmarks
- Difficulties in establishing a chronology, fatigability, noise sensitivity
- Reading difficulties, phonic mistakes, paralexia, visual mistakes (b/d...), very weak spelling
- Better results in speech activities. Better understanding of orally given instructions
- Normal learning capacities with any medium but written language.
