I've never heard this. As one who has been dysletic for decades (past tense sedaced), the main problems seem to be the reversal of letters and numbers along with a (slight in my case) disconnect of words with their referents. (The map really isn't the territory.)
I do know of people considered dysletic who see numbers in arbitrary geometric patterns. Like:
44 477 34 8....
12 743 16 194....
2 45 466 744....
..............
Theses people have trouble with math; I had to teach them algorithmic rather than intuitive methods of computation. Fortunately I see the numbers in a line (ordered by magnetude). (I do see days of the year in a circle, Christmas on top and July 4 on the bottom. I know one person who sees a year as a horshoe with November connecting the ends.)
Studying music does seem to help with dyslexia. Perhaps it's because music uses different brain circuits or because one just learns more discipline.
Could you please define this word, or identify it as a typo? I am either interested in learning a new word or trying to figure what you were saying. ;^)
