Dyslexia is receiving wide spread attention owing to the combined efforts of concerned parents, care givers, educationists and medical practitioners. Parents of Dyslexic children have taken the initiative to bring Dyslexia to the forefront of public awareness and about the various learning disorders. The most prominent factor that causes Dyslexia is inherited genes. This aspect has been given a great deal of attention in recent years due to constant research which has revealed that this feature along with hearing problems at early age may be the prime reasons that causes Dyslexia.

It is becoming apparent through intensive research that Dyslexia is generally found in family members who are normally left handed. This, however, does not indicate that a Dyslexic child is left handed and Dyslexic parents would give birth to Dyslexic infant. But the factor that causes Dyslexia stresses the fact that one-third to half of the children has learning difficulty problems that have already been identified as having Dyslexia in their family while it has also been noticed that half of the family members are left handed!

Technical advancement has facilitated research on factors that causes Dyslexia and the study reveals that brain cells, especially the “ectopic” group of cells, which should have reached the brain surface during the child’s development stage in the fetus, failed to make the journey. This group of cell residing in the left and frontal areas of the brain is important for the development of reading and writing skills. Another segment of the brain which deals with the ability to discern moving images is found to be smaller in size and causes Dyslexia in a Dyslexic child. This feature creates problems during reading as the brain interprets letters and words differently.

A child’s hearing difficulties at the early stage causes Dyslexia. Frequent cold and throat infection during the first five years results in ear blockage which might impair the child’s hearing capabilities. If the condition remains undetected at an early stage then the developing brain of the child fails to link between the different sound intonations. This causes Dyslexia as lack of proper hearing may hamper the child’s “phonemic” awareness. Delay in “phonemic” awareness causes Dyslexia and it is, therefore, imperative to take corrective action at the initial stages whenever the child suffering from frequent cold and cough complains of hearing problems.

Inherited genes along with early hearing impairment may be the prime factor that causes Dyslexia since the child faces difficulties when dealing with letters / alphabets. They need constant emotional support from care givers throughout their schooling, college years and later in their professional lives. Such intervention therapy makes them behave like normal children in their adult lives. Poor hormonal development or malnutrition during the early stages of fetal growth has been attributed to the birth of Dyslexic children. Later this problem is magnified by poor parenting and neglect. However, proper attention by care givers and medical professionals can diminish the intensity of the malady and cure the child to a great extent.
