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. on that point is rough evidence that dyslectic flock sh ar a group of genes on social function of chromosome 6 which is close to the MHC genes that potence the insubordinate system. This idea is support by the evidence that dyslexics often tend to suffer from disorders of the immune system such as asthma and rhemutoid arthritis. One guess which attempts to relieve how dyslexia whitethorn be caused by tasks in the brain is Gerschwinds possibleness. He claims that high testosterone in the fetus could lead to suffering of the left hand-hand(a) 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 field the brains of two dyslexic large number (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 credit line of battle that testosterone interferes with brain education in the foetus. However, there are problems with this evidence. The brains canvas were of potents, but females wedge dyslexia too. Males and females hear sounds in diametrical part of the brain then evidence relating to males cannot be speak to book to both sexes.

Also, the exemplar 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 determine that the living brains of dyslexics would display the akin 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 verbalize whether this...
