Attached to fibers, the neurons travel to the cerebral cortex, which contains the language centers. Here they hit a barrier, stop and take their place in layers above previously deposited neurons, (which is normal). In the brains of dyslexics, however, there are breaches in the barrier and the neurons enter them, leaving clumps of nerve cells, called ectopias, which appear to interface with the brain's ability to receive and transmit certain messages. .
Researchers are now finding that dyslexia tends to run in families. If you or your relatives have dyslexia, that means that there is an increased chance that your own child could have it. Unlike what most people think, dyslexia is not to be blamed on the parent or negligence in teaching reading and writing. Dyslexia is not any ones fault. It simply occurs when the barrier in the language center of you brain cracks during development. In some experiments done by the University of Montreal, scientists are comparing non-dyslexic children readers to dyslexic adult readers. In most cases, the adult dyslexics were at about the high school level. When the adult dyslexics were compared to non-dyslexic third graders in matching sounds with letters, the dyslexics scored lower than the eight and nine year olds that were tested. It's not just a visual problem, actually they may see the letters fine, it is more of a comparing problem. Dyslexics usually cannot spell simple words by just hearing someone speak them to them. Some of the most confusing words for them are cat and dog. A dyslexic student may write 15 instead of 51.
Although, over time, the effects of the symptoms can be fine-tuned with training, they never go completely away. As said before, dyslexia is not a disease. It cannot be cured with any pill or medicine. The only cure so far is many long and slow classes of multi sensory sessions. These sessions go through each letter, sound, syllable, etc.
