Breakthrough in origin of DYSLEXIA discovered

Current thinking has been that Dyslexia is a neurological issue rather than a "mechanical" issue.

However, two French physicists working at the University of Rennes (one is 77 but still likes to work) have just shown in a study of University students that Dyslexia is linked to a problem of symmetry in the eyes, specifically in an area on the retina called the "Maxwell spot centroids". The Maxwell area was discovered in the 19th century and is only 150 microns in diameter. There is some technical specificity with the MSCs as well in that red and green cones are present but not blue.

In a few words, people who are not Dyslexic have MSCs that are asymmetric. Which mean that one eye has a MSC that is round and the other is more like a potato shape. The brain is given information from the dominant eye (the round one). This is why people who look through a jeweller's loupe will close the non-dominant eye to see. Same idea with someone looking through a scope on a rifle. When reading etc. with both eyes open the brain is given information that is prioritised from one eye.

In the case of a dyslexic person the two MSC are both round so there is symmetry. The brain is given information from both equally and gets "confused", especially with letters like b, d, q.

It is not really clear yet how this information will help dyslexic people in the short term (the study was just published in the Royal Society UK) but one thing that was mentioned in one of the articles (FR) was that the researchers were also playing around with a special lamp that they developed that helped the dyslexic subjects to read more easily. No more detailed information was given other than is was a type of strobe with LED lights that made reading easier.

Ideally this breakthrough will move study in a new direction that will be helpful to people with Dyslexia.

Re: Breakthrough in origin of DYSLEXIA discovered

Had a t-shirt many moons ago sold in aid of the U.K. Dyslexia society.

DYSLEXIA, was the main word with the anagram, DAILY SEX, crossed out.

Made me and a lot of other people smile, as well as trying to make people aware.

Re: Breakthrough in origin of DYSLEXIA discovered

If that is the problem, shouldn't the solution be to just shut one eye?

Indeed, some dyslexics are taught just that, as one of several strategies of managing the condition. This new research seems to provide a scientific basis with which to explain why that can, at least sometimes, help.

From what I picked up in the articles, the issue ties into the neural pathways that are developed/laid down when a person is young and starting to read. The problem of the symmetry creates problems in the pathways that are not created correctly and stay with the person as they get older. As such, the solution of shutting one eye can not overcome the issue that has been created.

That makes sense. Those I know who find it helps to cover one eye were taught to do so at a very early age, before or just at the when starting school. In both cases, remarkably, by a Wise Granny Of No Formal Education.

Re: Breakthrough in origin of DYSLEXIA discovered

Richard Branson is behind a new Charity 'Made by Dyslexia", whilst Dyslexics may do poorly at school, they do better than average in their careers. 1 in 4 are millionaires v 1 in 10 of the rest of the population (UK). It's actually a positive trait, a Dyslexic sperm bank has also opened.

Re: Breakthrough in origin of DYSLEXIA discovered

Following on from the LED lamp thing, many people use coloured plastic overlays (blue or yellow, "typically") to aid reading and processing. Never had a student cover one eye...

1 in 4?

I've had 4 major, long term relationships. All 4 are left handed. 3 are dyslexic. 3 have green eyes. All 3 of the dyslexics suspect there's a link to their left handedness based upon sharing that trait with other dyslexics they've met.

Re: Breakthrough in origin of DYSLEXIA discovered

I would take the 1 in 4 with a grain of salt. Lots of undiagnosed dyslexics. Dyslexics who do well, however, often learn to compensate, innovate.

I’m right handed and dyslexic.

I have always. Reading, listening to books, making up stories in my head.

The closing one eye thing makes sense. My dyslexia is concentrated on having problems with spacing on a page.

I am right handed & dyslexic, I have read a book by choice once every 10 years since leaving school. Technical manuals excluded. Due to forums on the internet I read & write about 100 times more than I did before 2000.

Re: Breakthrough in origin of DYSLEXIA discovered

I've never been diagnosed as dyslexic, but many times when putting pen to paper the letter that winds up on the page isn't the letter I meant to write - especially with b, p, and d. It comes out wrong, and I'm a bit bewildered. I obviously know how to write the letters properly and know what I want to write, but something gets lost along the way.

Anyone else have this issue? I don't have any problems with keyboarding, just manual writing.

Technical manuals just don't gel with me. I wish they came written as stories, regular books or textbooks.

I can figure out and visualize "how-to-do" by looking at the copleted object or action, but to follow a step-by-step thing is a drag for me.
