I agree with above posters.
Most of what I know is anecdotal. As kids age and/or become adults some learn to compensate or internalize strategies that help manage areas of weakness/LD.
For myself-- I have struggled with writing my entire life (the mechanics of getting pencil on paper in an organized fashion not the creative process) and likely would have qualified under the LD discrepancy model for mild/moderate written expression. That said- I struggled in school with written assignments.
As an adults, I have learned to adapt (writing is still my biggest weakness) so that is it not the onerous chore it once was. I type if possible and have someone proofread my work for assignments and papers. Spellcheck/GrammarCheck have been really wonderful tools for me to 'see' errors. Typing also helps since I can type faster than I can write and tend not to get quite as lost in the writing 'process'. Although, written work for college and post graduate work takes me longer than many.Writing/spelling will likely never come naturally, but it no longer has the huge impact on my life like it did in public school system.
Also due to my own experiences ( in addition to other events in my life that heavily influenced me), I went in to Special Education. I have learned a lot on how other people learn and ways the school system is set up.
Overall, I would say : It depends on a lot of factors.
But for a kiddo that struggles w/LDs in school- as an adult there are a lot of ways to work around it that simply are more difficult in the highly structured school setting. One former student that had a fairly severe reading disability has gone on to be successful at college using books on tape and taped lectures. He is an excellent theater student. He is able to memorize lines very quickly and excels in the college setting- which is something that was a bit of a struggle in public school.
Some students it just 'clicks' and others benefit from alternative teaching methods (Ortin-Gillingham for example) that allow them to learn more effectively for their learning style. Some kids continue to struggle with LDs in greater ways than others as they turn into adults. The severity of the LD and any other co-morbid conditions may also impact each individual. LDs are so very individual- it is hard to know kids outlook 10, 20, years from now.
