By "zombie apocalypse", you mean slow-walking infected, craving brains and infecting anyone they bite?

Or just, you know, a disease that kills you if you eat brains? Because that's kind of the exact opposite of what zombies do.

A prion that infected people rapidly, through saliva-to-blood contact, and had similar symptoms to rabies without the rapid death would be very similar to traditional zombie lore.

The protein would probably also have to effect the olfactory glands, creating an attraction to uninfected humans.
