A few clarifications regarding dyslexia
Two commonly held beliefs about dyslexia are that children with it see letters or words backward, and that the problem is linked to intelligence.
Both beliefs are considered to be wrong. The problem is a linguistic one, not a visual one, in dyslexia; and dyslexia in no way stems from any lack of intelligence. People with severe dyslexia can be and have been known to be of superior intelligence.
In fact, the effects of dyslexia vary from person to person. The only shared trait among people with dyslexia is that they read at levels significantly lower than is typical for people of their ages. Dyslexia is not the same as reading retardation which may reflect mental retardation or cultural deprivation.

Named by John Stanton McIntosh (1923-), Walter P. Coombs, Jr., and Dale Alan Russell in 1992.
