Our king

dyslexia can lessen to the point of not really being noticeable. Its like that with a lot of things of that sort.

I have Dyslexia and trust me all we do is learn to work around it and use tricks and gimmicks to make it easier for us. It never changes.
In my case I will stumble when I talk, I have trouble reading small and tight print, I can not read cursive at all no matter how hard I try, I forget how to spell simple words they become foriegn to me, and many other problems. But I could read at college level when I was in elementary school.
My Dyslexia was discovered when I was in 2nd grade. And yet I still have every single problem I started with.
It does not lessen it does not disappear.
We just learn how to hide our trouble and work though our everyday lifes.
It never goes away.

I also have dyslexia. That does not qualify me to speak as an authority about the disorder itself by itself. Neither my experiences with it nor your experiences with it are enough to constituent any amount of "proof" either direction. It requires a moderate amount of actually having done research and not just using personal experience as law. Mine has lessened over time to the point i have very few problems except with maps and other mixes of text and not text as well as a few specific words that "replace each other" when previously i had trouble with text being fucky where it isnt today.
Not only is it possible for someone to have dyslexia lessen in extremity the opposite is also possible.
