EVERYONE is Dyslexic.
When the brain is functioning properly, the dyslexia mechanism is responsible for reflex relations -- like catching something, hitting a baseball, or blocking a punch.
When the process malfunctions, as it does in a given percent of the population, it affects the ability to read -- the brain fails to adjust the visual image of letters. But, it has a survival benefit associated with hunting and exploring...it also benefits pattern recognition.
Until we had universal education, it went unnoticed. Other than when the dyslexic was a hunter, explorer, or artist...and they were superior at it.
With universal education, it manifested as a reading disorder..and was called mirror reading because the letters appeared to the individual to be upside down and backward.
There are other -- not natural -- forms of acquired dyslexia. These result from brain trauma -- and it need not be massive trauma. A blow to the right spot on the head or an illness can cause it to develop. Basically, the wiring of the brain is disrupted and resets the natural optical mechanism.
