Dyslexia is a very common problem and has an effect on the way our brain understands words. The most common signs of dyslexia are reading and writing problems. On average, fifteen percent of all people have dyslexia. A person can have dyslexia even if he or she is very smart or educated.

At the end of the 20th century, scientists did much research about dyslexia and discovered some of the reasons that people are dyslexic. A professor who did research in the 1980s and 1990s looked at the brains of dyslexic people who had died. He found that some parts of the brain were not connected very well, and that this happened during the fourth month of pregnancy. This problem has a big effect on the left half of the brain. The newest research shows that three genes are the reason for dyslexia: the second, the sixth with the DCDC2 part and the fifteenth.

One problem that causes dyslexia is a defect at the central hearing nerve. This problem can not be found with a normal hearing test, so a special doctor has to do special tests to find it. It means that people with heavy dyslexia are sensitive to loud noise, may have problems speaking, and may not be able to concentrate. It may also cause problems with rhythm and melody of music.

[edit] Diagnostics

In order to tell if a child has dyslexia, he or she has to be seen by a doctor. A child can be called dyslexic if he or she cannot read or write well and there is no other reason for the problem. Doctors are trying to create early tests to help find out whether a child has dyslexia before they are old enough to go to school. If this happens, a child can start to be treated very early, and they may have fewer problems at school.

[edit] Therapy

Children with dyslexia can be helped. One way teachers help dyslexic students is to break words into different sounds. The student must learn how to write the different sounds and create words. This helps with reading and writing. Some people believe that dyslexic children can read and write better if they put pieces of colored paper on top of what they are reading.
