Hello I know of a person who has suffered what seems to be a heart attack. They may have diagnosed him as brain dead however he does not need a heater because he is able to generate his own heat. Along with this he is able to urinate and creates a lot more waste. Does this mean he is in fact not brain dead? He was also found with an infection somewhere in his body, doctors have not located where, but does a "brain dead" person get fevers?
