Bad eyesight could constitute learning difficulties. If the defect is corrected, dyslexia as a result of poor vision consequently disappears. Also, there is genetic explanation to the causative factors of dyslexia. The New scientist magazine (1996) reported a research. ‘’Exploiting the known association, the genes involved in autoimmune diseases such as migraine and asthma, and those responsible for dyslexia’’. The report further explained that because dyslexics and their relatives are more likely to suffer from autoimmune diseases, scientists believe the genes for dyslexia occur in the region of the genome that houses these disease genes.
Similarly, the part of the brain that controls posture, balance and cordintion is called the cerebellum. Some scientists claim that it also plays a part in our thinking and language processing. Interestingly, researchers at Sheffield University in England have develop a dyslexia test that involves balance coordination ( British Dyslexia association 1996). They reason that faults in the cerebellum prompt healthy areas of the brain to compensate.
