Dyslexia is a learning disability that makes reading, writing, spelling and sometimes speaking difficult. It is caused by an impairment of the brain’s ability to translate images received from the eyes or sounds received from the ears into understandable language. Dyslexia is not an intellectual disability, since dyslexia and IQ are not interrelated.
