I plan to work the explanation into the story sometime in the future but ill answer it a little now for clarity since you asked. ^_^ the curse is meant to work as a sort of virus that infects the hosts blood transforming them. for most who are infected, they lose there sense of self for the most part and lose there memory. however that isn't always the outcome of being curse. some who get infected are able to retain there sense of self through the transformation but nobody knows why some retain there identity.
