Potential Reasons For Rise In Dyslexia

Educational standards and methods of instruction continue to improve over time.  Sadly, at the same time more and more children are being diagnosed with one particular learning disability:  dyslexia.  It is disturbing to see that child psychologists are reporting dyslexia in children as early as three to five years of age. While there aren’t any cures for dyslexia, better understandings can help to treat the symptoms. 

The standard theory of the evolution of dyslexia doesn’t seem to apply to this trend.  The hypothesis states that the learning disability is created when instruction and learning is introduced later in the neurodevelopment stages of children.  Those who developed this hypothesis determined that late introduction to educational stimulation caused a variety of learning problems, but children are constantly learning, from day one they are taking in sensory perceptions from their environment. 

What does appear to be true is that the main causes of this learning disability come from how the brain processes information from spoken and written language.  This information is neurologically impaired by certain factors in the brain, resulting in dyslexia.  Dyslexia is not related to intelligence; even the most brilliant people may be affected by this disorder that originates in the brain.

One correlation associated with the disorder is heredity.  The implication is that entire families and generations may have the same processing disability.  There is a lot of interest and research currently being conducted in this area of the study of dyslexia, and there is still much to be learned.

Interesting developments in the study of dyslexia include the discovery of a network of cells beneath the surface of the brain in people with dyslexia.  In the normal neurological development process these cells move from just beneath the surface to along the surface shortly after birth.  In dyslexic people the cells do not make the move for some reason.  These ectopic cells are found in the front and left of the brain, the very areas known to be important for performing reading and writing.

Knowing these causes, doesn’t explain the growing number of dyslexics in our population.  Increased numbers of dyslexia require additional funding and research to get to the root of the problem.  In the meantime, more and more time and effort must be spent on therapies and structured learning environments and methods to assist dyslexic kids with learning. Additionally, more research may also help to identify trends for parents learning how to deal with childrens adhd.
