This is stuff that I deleted from the dyslexia page but that I am preserving to possibly replace in the future-- it was written by other people and looks redundant, but I didn't want it to be completely lost:

Most theories focus on non-primary areas in the frontal lobe and the temporal lobe.

Much of the current scientific research focuses on the hypothesis that dyslexia stems from a deficit in phonological awareness. This hypothesis suggests that affected individuals have difficulty analyzing the words they hear into discrete segments (such as phonemes), which in turn leads to difficulty learning spelling-sound correspondences.

Other research focuses on the theory that dyslexia results from a magnocellular deficit related to visual processing, or that it is related to a cerebellar deficit.

Another theory suggests that dyslexia is not a disorder or deficit but a naturally occurring cognitive variant which did not cause any problems until reading was imposed on the general public just over 150 years ago — in other words no biological adaptation has occurred for this unnatural cognitive task.
