Dyslexia, common in children, is a learning disorder in which an individual has difficulty reading despite having had adequate access to education and sufficient intelligence. There is a difference in the brain architecture that causes a certain part of the brain of a person with dyslexia to have trouble decoding the written word. There are over 20 million children in the United States between the ages of 5 and 9 and as many as 1 to 2.4 million of them could have dyslexia.
Dyslexia can be caused in two ways, by inherited factors and by hearing problems at an early age. There are 2 factors in inherited factors ; ectopic cells (bunches of cells beneath the surface of the brain) and the magno-cellular system (which deals with our ability to see moving images). These ectopic clusters of cells are mainly found in the left and the front part of the brain, the areas which are important for reading and writing, but in normal person this ectopic clusters lie on the surface in the brain.

The researchers found that boys were two to three times more likely to suffer from dyslexia...
