Risk Factors and Causes of Dyslexia
A specific learning disability characterized by difficulty in learning to read is developmental dyslexia. Some dyslexics also have difficulty learning to write, to spell and, sometimes, to speak, or to work with numbers.
We see we do not know what causes dyslexia, but we do know that it affects children who are physically and emotionally healthy, academically capable, and who come from good home environments. Many dyslexics in fact, have the advantages of good schools, high mental ability, and parents who are well-educated and value learning.
To a broad range of reading problems and researchers School children are subject have discovered the cause of many of these problems. Most teachers today, accept these research findings and use them in planning their instruction, but there remains a small group of children who have difficulty in learning to read for no apparent reason. These children are called dyslexic. Although estimates of the prevalence of dyslexia are hard to find, it is estimated that as many as 15 percent of American students may be classified as dyslexic.
