Dyslexia
Reading disorders in children can be manifest by below expected reading abilities in an otherwise normal child. “Dyslexia” is a term used to denote a child who has a “primary” reading disability, not one caused by problems such as mental retardation or poor education.
All current research indicates that dyslexia is a disorder of language. A defect in language processing causes the reading disability. Vision problems DO NOT cause reading difficulties associated with dyslexia.
Because reading disorders are due to a primary language dysfunction, they should be treated as such. Treatment requires a multidisciplinary approach involving educators, psychologists, and physicians.
