Rudellian brain fever

Rudellian brain fever is a disease.

In 2373, Miles O'Brien considered the possibility that Keiko O'Brien was suffering from Rudellian brain fever from an outbreak on Bajor after claiming to have be controlled by an entity that O'Brien later learned was a Pah-wraith. 

Andrea M'Benga thought she might have contracted Rudellian brain fever after collapsing on in 2374. Julian Bashir diagnosed M'Benga's collapse as being caused by severe exhaustion brought on by overwork, not Rudellian brain fever.
