Dyslexia results from an inability to recognize and memorize the visual form of words. As a result, the child has difficulty associating sounds with letters and syllables.
Given the complexity of neural circuits and the structures involved in reading, there are many possible causes for dyslexia. A number of neuronal anatomical and morphological abnormalities have been observed by the researchers. However, their meaning is not yet known, and no causal link has been established. The weight of genetic factors has been illustrated by scientific studies of families and twins in particular. It has even been confirmed by the identification of four genes involved in dyslexia. But if genetic causes play an essential role, this one is not exclusive.
Linguistic causes are even put forward, some languages being more conducive to dyslexia than others. Finally, if the teaching methods do not seem to be incriminated in the appearance of the disorder, the socio-family and educational environment could have an influence. However, the complexity of learning to read, coupled with the complexity of the brain, does not facilitate accurate understanding of the disorder.
Other psychological difficulties may be associated, such as AD / HD (attention deficit with or without hyperactivity). Because of the difficulties of concentration, this disorder can participate in the maintenance of dyslexia.
Many questions remain unresolved. In the meantime, the research continues, and continues to work hard to bring us other answers ...
