Here is an interesting study from Stanford that gives support to what dyslexics have said for years - it's harder for them to read.
The fundamental difference in this study is that here dyslexic and non-dyslexic subjects were matched for reading performance - so differences in brain activation weren't due to efficiency of reading issues.
It's not surprising why so many bright dyslexics will fall between the cracks in the school system - even if they master the code of reading for comprehension, they fail to be identified as having a disability and are penalized for not finishing tests or papers, or required reading on time.
A study such as this also underscores the problems of defining dyslexia on the basis of reading performance.
