As many as 20% of all children in the United States suffer from some form of the learning disorder
called dyslexia.
Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use infor-
ination in a di价rent way.One of the world's great thinkers and scientists Albert Einstein was dyslexic.Ein-
stein said that he never thought in words the way that most people do.He said that he thought in pictures in-
stead.The American inventor Thomas Edisoii was also dyslexic.Dyslexia first was recognized in Europe and
the United States more than 80 years ago.Many years passed before doctors discovered that persons with the
disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are
different,In most people,the left side of the brain一the part that controls language一is larger than the right
side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this
difference.However,research has shown that dyslexia is more common in males than in females,and it is
found more often in persons who are left-handed.No one knows the cause of dyslexia,but some scientists
believe that it may result from chemical changes in a baby's body long before it is born.They are trying to
find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching
help.After they have solved their problems with language,they often show themselves to be especially intelligent
or creative. Many great thinkers and scientists in the world are dyslexic.
