The originof the name dyslexia comes from the word “dys”, stating that there is somethingwrong, and “lexia”, labeling letters and words. This is the condition found inboth children and adults. Speaking about dyslexia, this explanation of the condition’sname is true, since this is a problem associated with words. Doctors characterize this condition as problems associated with spelling,writing, reading, but also with memory and hearing difficulties. People sufferingfrom dyslexia are not capable to relate sounds and written letters withthe actual words, so they usually have many problems with words, symbolsand numbers as well. It is very difficult for them to solve some mathematicalproblems, understand or even memorize something they have seen written. These patients may also experience lack of physical and sensorycoordination as symptoms of dyslexia.
You should knowthat IQ (intelligence quotient) and dyslexia are not related, and that people havingthis problem are not less smart than those without it. For manygenerations, people that were very slow in learning, had difficulties with math,spelling, grammar and pronunciation were considered simply lazy. Teachers weren’teducated to know that a problem such as dyslexia actually exists, and becauseof that, students with these problems as often labeled as sluggish. That haschanged and people suffering from dyslexia are now recognized as someone who needs additional attention.
Nowadays, there is a test for anyoneexperiencing some of the symptoms mentioned above, known asdyslexia test, used to detect and evaluate the condition, and also to identifythe cause of the problem. Knowing the type of the condition is important, becauseof the appropriate treatment.
Scientists foundseveral reasons that are responsible for dyslexia. Magnocellular pathway or Mpathway, responsible for the production of brightness and motion is one of theidentified causes. Whenever there is an inconsistency in this pathway, whichprocesses optical impulses, people are likely to suffer from dyslexia.
Parvocellularor P visual pathway, if underdeveloped, is another cause of dyslexia. This problemmakes people with dyslexia enable to differentiate details and elegant colors.
When theleft and right hemispheres of the brain don’t communicate properly, there isalso a chance that the person with this condition will develop dyslexia. Sensory informationthat is not comprehended as it should be in the brain can also lead todyslexia. Actually, any sensory coordination problem can be the cause of thislearning problem in both children and adults.
