Hi Eileen,

(from the Oxford dictionary)
- definition of syndrome is a group of symptoms which consistently occur together.
(Sounds better than "a bunch of symptoms we *can't* put a name to"..)
- definition of disease is a disorder of structure or function in a human, animal, or plant, especially one that produces specific symptoms.
(Sounds better than "a bunch of symptoms we *can* put a name to"..)

Since all diseases produce a bunch of specific symptoms...

The medical naming seems to depend on whether they can identify an originating cause. Notice how many names RSD/CRPS/Causalgia etc has... but I expect that if tomorrow some Doctor Smith produced definitive research proving that it was caused by eating too many Hershey bars it would instantly become "Smith Syndrome" or "Hershey's Disease".

Doctors shmoctors...I think it's just code for the medics: disease = we know something about it; syndrome = we don't.

Cynical? Moi?
all the best!
