However, emotional problems often arise because of it. The latter usually cover a variety of reading skills and deficits, and difficulties with distinct causes rather than a single condition. Some sources, such as the U. National Institutes of Health, define it specifically as a learning disorder.
As much as percent of the global population has it — and despite its commonality, its causes remain poorly understood. A remarkable new piece of research has now concluded that strange patterns of light receptors in the eyes may be the primary cause of the condition.
Writing in the Proceedings of the Royal Society Ba team at the University of Rennes found that the cells responsible for absorbing incoming light within the eyes are arranged differently in people diagnosed with dyslexia.
In people without dyslexia, these cells are in asymmetric layouts; one eye features one pattern, and the other features a different arrangement.
This allows complex, multi-angle light sources to be absorbed differently through each eye. Dyslexic people appear to have symmetric arrangements, though, with both eyes containing the exact same layout of cone cells.
Their brains cannot properly distinguish between mirrored shapes that well. This asymmetry can be seen with unbelievable precision.
At the center of the retina — the fovea — there's a small spot that contains no blue cone cells. In non-dyslexic people, this spot is round in the dominant eye, and somewhat warped in the other eye. In dyslexic people, both eyes have the exact same round spot. In any case, the identification of this possible physiological cause of dyslexia is nothing but good news.
After all, if you know what the problem actually is, you can start to find a way to fix it, if, of course, you see it as a problem in the first place. People with dyslexia sometimes see it as not something that needs to be "fixed," but a type of creative advantage.
The researchers are well aware of the potentially dramatic implications of their work. It's worth pointing out that this is just one study, and that plenty of other researchers view dyslexia as a neurological trait. Perhaps these visual differences are a consequence, rather than a trigger, of dyslexia.
At the very least, this new study will reinvigorate the scientific debate around the subject.Watch video · French scientists believe they have identified a physiological cause for dyslexia which could lead to a potential treatment.

Students with dyslexia usually experience difficulties with other language skills such as spelling, writing, and pronouncing words. Dyslexia affects individuals throughout their lives; however, its impact can change at different stages in a person's life. Samuel Terry Orton, one of the first to recognize the syndrome of dyslexia in students, suggested that teaching the ‚Äúfundamentals of phonic association with letter forms, both visually presented and reproduced in writing until the correct associations were built up,‚Äù would benefit students of all ages.
Dyslexia, a learning difficulty that affects reading, writing, and spelling skills, is more widespread than you probably think. As much as percent of the global population has it – and.
History of dyslexia research Jump to They sought to discover if a conflict between spontaneous orientation of the scanning action of the eyes from right to left and training aimed at the acquisition of an opposite direction would allow an interpretation of the facts observed in the dyslexic disorder and especially of the ability to mirror.

Generally, symptoms show up as problems with accuracy and fluency in reading and spelling. But in some kids, dyslexia can impact writing, math and language, too.
