It's always seemed crazy to me when people talk about "the cause" of dyslexia. There are so many brain processes involved in reading, that any number of issues could be a cause of someone's dyslexia. It's like saying "the cause" of water drainage issues is beavers.

I do think a lot of researchers propose different subtypes of dyslexia nowadays, with different explanations and potentially different treatments.
