Dyslexia is a learning disability, the exact effects vary from person to person, though the overall idea of struggling with learning is the same. It is a life long disease meaning children that are diagnosed will continue to have dyslexia in their adulthood. Many people don?t discover it until they are adults, through a dyslexia test. The exact cause of dyslexia is not certain but but here are the various theories:
Neurobiological and Genetic- Some believe that dyslexia is inherited through genetics. If a person has dyslexia then chances are their parents, grandparents, or aunt etc. had dyslexia.
Brain Development- Some researchers believe that dyslexia is the result of improper neuronal migration. Neurons, nerve cells that form the brain, develop away from where they actually need to be. This failure to migrate causes the brain to not develop fully.
Early Age Hearing Problems- Other researchers believe that if there is a problem with hearing at an early age a child will not be able to hear correctly how letters are supposed to sound causing the brain (which is at a crucial developing stage) to fail to make the connections between letters and their correct sound. This lack of letter recognition can be a life long struggle.
Crossed Wiring- There are studies that suggest that a child with dyslexia will use the right side of their brain for language work where a child without dyslexia will use the left side. The right side of the brain is not the side that is made to comprehend language, suggesting that some where those wires got crossed. This dependence on the right side of the brain makes a person with dyslexia have to work twice as hard to comprehend language.
A Combination- The majority of people believe it is or can be a combination of all of the above reasons. With no known scientific cause or explanation, many say this is probably the most likely answer.
Knowing the cause of dyslexia is not essential to understanding how to deal with it. Although finding the origin may lead to its prevention and/or cure, not knowing the cause doesn’t hinder the coping process. It will be an exciting breakthrough when science can explain the mystery of dyslexia. If you at all suspect you have dyslexia you should take the time to get tested, so you can begin learning the proper coping skills.
