One of the interesting things about reading disorders is that children with a positive diagnosis tend to show different patterns of brain activity that non-identified children. This is a brief summary of reserach (too brief in my opinion - I would have liked to have seen more of it) in which a treatment showed positive results as shown through pre- and post- fMRI patterns. Specifically, the LD groups post fMRI patterns more closely resembled the non-LD children's fMRI patterns.
