Rudellian brain fever is an infectious disease, which can cause mental problems.

In 2373, Miles O'Brien at first speculated there had been an outbreak of Rudellian brain fever on Bajor, when his wife told him she wasn't Keiko; in fact, however, Keiko's body had been taken over by a Pah-wraith. (DS9: "The Assignment")
