Did anyone else see this article on Discovery News (free site, no registration)? http://dsc.discovery.com/news/2008/04/08/dyslexia-language.html
The first paragraphs says
Dyslexia affects different parts of children's brains depending on whether they are raised reading English or Chinese. That finding, reported in Monday's online edition of Proceedings of the National Academy of Sciences, means that therapists may need to seek different methods of assisting dyslexic children from different cultures.
This is huge, since it'll be a good step in figuring out what causes dyslexia and how it works, which will lead to better treatments.
