Dyslexia

Dyslexia is a specific learning disability. It usually shows itself in problems with written language, particularly with reading and spelling. It is its own unique problem, or disorder, and it is not the result of low intelligence, or problems with vision or hearing.

Dyslexia is a problem with how the brain processes the signals that come into our brain, especially the symbols of our language. When the brain has problems processing these symbols of language through the visual processing pathways there are reading problems and a visual dyslexia. When the brain has problems processing these sounds of language through the auditory processing pathways there are other problems, auditory dyslexia.

Dyslexia is not related to IQ.
