Scientists may have found a cause of dyslexia


A duo of French scientists said on Wednesday (Oct 17) they may have found a physiological, and seemingly treatable, cause for dyslexia hidden in tiny light-receptor cells in the human eye.

In people with the reading disability, the cells were arranged in matching patterns in both eyes, which may be to blame for confusing the brain by producing "mirror" images, like "b" and "d", the co-authors wrote in the journal Proceedings of the Royal Society B.

Like being left- or right-handed, human beings also have a dominant eye.

In dyslexic people, both eyes have the same, round spot, which translates into neither eye being dominant, they found.

The team used an LED lamp, flashing so fast that it is invisible to the naked eye, to "cancel" one of the images in the brains of dyslexic trial participants while reading. This enables the participants to read correctly.

About 700 million people in the world are known to suffer from dyslexia - about one in 10 of the global population.
