Dyslexia Causes
Violations of the combination, recognition, analysis, and memorization of sounds cause problems with the phonological process. With dyslexia, violations of verbal speech, writing, and understanding of written speech are noted, which in the future can lead to problems with memory, finding suitable words, and speech formation.
Familial dyslexias [9] are not uncommon. Children from these families often suffer from this disorder. Scientists believe that dyslexia occurs due to congenital malformations of the central nervous system. It is believed that this is due to disorders in the areas of the brain of the left hemisphere that are responsible for speech motor skills and speech reproduction. If there are violations in the right hemisphere, then the person has problems with word recognition.
Dyslexia does not include abnormal eye movements and visual-perceptual problems, although they also affect learning and understanding of words.
