Although dyslexia is a learning disorder in an otherwise normal person, it has been proved that the brain of a dyslexic person develops differently from that of others.

Studies has shown that the inborn wiring system of the brain related to developing mental skills is different in dyslexics and hence being the base cause of this disorder. 

The wiring system of the brain or the neural pathway is the process that codes the information the sensory organs receive and stores it in the brain for future assimilation. This information is later used to assess situations and develop response patterns to the situations, increase the muscular co-ordinations according to the situations, or even help us in understanding and comprehending the constant inputs our brain is getting in terms of every day activities, school procedures etc. 

In a dyslexic child, even these minor acts of comprehension and usage may take a lot more time and skill than a normal child.

Hence one school of thought has concluded that dyslexia is a condition that is largely inborn and not the result of poor parenting or environment. However another school of researches has strongly disagreed and believes that while dyslexia may sometimes be inborn it is often attributable to lack of phonics training when learning to read and the preponderance of the whole language system.

In one of the theories about dyslexia, researchers Geschwind and Galaburda had focused on other symptoms like creativity, visual abilities, left handedness, allergies etc to link it to raises in hormones like testosterone levels in pregnant mothers during the first trimester that may lead to a variant brain structure that may lead to dyslexia.

In other studies, dyslexia had been linked to genetic reasons. According to research conducted by M. M. Nothen and others, the inability to learn spellings can be linked to a gene called 15q21 of chromosome 15

Dyslexia is a life long condition and so, it may have different effect on an individual at different stages of life. It is seen that a dyslexic child may have great difficulty in coping with normal schoolwork although in other aspects like sporting activities or extra curricular activities he may show some interest and abilities. It is here that they need to be encouraged tremendously so that they can over come their low self-esteem.
