One possible cause of dyslexia is that it emanates from neurological (brain) factors. This is a biological explanation. thither is some order that dyslexic flock make do a group of genes on part of chromosome 6 which is compressed to the MHC genes that dominance the immune system. This idea is supported by the show that dyslexics practically tend to suffer from disorders of the immune system such(prenominal) as asthma and rhemutoid arthritis. One guess which attempts to explain how dyslexia may be caused by problems in the brain is Gerschwinds theory. He claims that last testosterone in the fetus could lead to damage of the left cerebral cerebral hemisphere of the brain, which ultimately may cause dyslexia to arise. There is some show to support this theory - it is taken from post mortems. Gershwind study the brains of twain dyslexic people (after death) and found that there was damage in the left hemisphere of the brain, which had been caused either before or during birth. physical studies also line of battle that testosterone interferes with brain development in the foetus. However, there are problems with this evidence. The brains canvas were of males, but females push dyslexia too. Males and females nail sounds in different part of the brain and so evidence relating to males cannot be generalised to book to both sexes.

Also, the sample size of only 2 dyslexic brains is very small, so the results cannot heretofore be applied with presumption to all male dyslexics either. The brains study were dead and there is no federal agency of determining that the upkeep bra ins of dyslexics would display the same dama! ge in the left hemisphere that the dead brains did. Another problem is that only dyslexics were studied - the results were not compared to non-dyslexics therefore it cant be said whether this...
