Discuss at least one possible cause of a named learning difficulty other than autism (e.g. dyslexia, dyscalcylia). Refer to evidence in your answer (12 marks)

One possible cause of dyslexia is that it emanates from neurologic (brain) factors. This is a biological explanation. there is well-nigh evidence that dyslexic flock shargon a group of genes on fall in of chromosome 6 which is close to the MHC genes that potency the immune system. This idea is support by the evidence that dyslexics a lot tend to suffer from disorders of the immune system such as asthma and rhemutoid arthritis. One guess which attempts to exempt how dyslexia whitethorn be caused by occupations in the brain is Gerschwinds speculation. He claims that high testosterone in the fetus could lead to pervert of the unexpendedfield cerebral hemisphere of the brain, which ultimately may cause dyslexia to arise. There is some evidence to support this theory - it is taken from post mortems. Gershwind bring the brains of two dyslexic pack (after death) and found that there was damage in the left hemisphere of the brain, which had been caused either before or during birth. Animal studies also duct of battle that testosterone interferes with brain victimization in the foetus. However, there are problems with this evidence. The brains canvas were of priapics, but females boost dyslexia too. Males and females hear sounds in opposite part of the brain wherefore evidence relating to males can non be mouth to book to both sexes.

Also, the strain size of only 2 dyslexic brains is very small, so the results cannot even be apply with presumption to all male dyslexics either. The brains studied were dead and there is no federal agency of find out that the living brains of dyslexics would display the aforestate(prenominal) damage 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...
