Definition of Dyslexia
Dyslexia: A specific reading
disability due to a defect in the brain's processing of graphic symbols. Dyslexia
is a learning disability that alters
the way the brain processes written material.
Two commonly held beliefs about dyslexia are that children with it are prone to seeing letters or words backward, and that the problem is linked to intelligence. Both beliefs are incorrect. 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 brilliant.
The effects of dyslexia, in fact, vary from person to
person. The only shared trait among people with dyslexia is that they read at levels significantly lower than typical for people of their age.
Dyslexia is different from reading retardation which may reflect mental retardation or cultural deprivation.
The treatment of dyslexia should be directed to the
specific learning problems the person has. The usual course is to modify
teaching methods and the educational environment to meet the specific
needs of the individual with dyslexia.
The prognosis (outlook) for
people with dyslexia is mixed. The disability affects such a wide range of
people, producing different symptoms and varying degrees of severity, that
predictions are hard to make. The prognosis is generally good, however, for
individuals whose dyslexia is identified early, who have supportive family and
friends and a strong self-image, and who are involved in a proper
treatment program.
