Excerpt from ihealthdirectiry
Dyslexia’s definition according to the National Institute of Health is that dyslexia is a learning disability which causes a child to have problems in their ability to read, write and spell according to their intellectual abilities. It is one of the most common learning disorders that affects children today and it stays with someone their whole life. Dyslexia can range from mild to severe. Treatment for dyslexia can be very successful if found and treated early in the child’s life.
Children who have dyslexia have problems with reading, writing and spelling due to the fact that their brain cannot translate information properly. The brain is unable to properly translate the images that it either sees or hears into something that is understandable for the child. However, children who have dyslexia have average intelligence. Mental retardation or brain damage are not related to this problem.
