Hi Everyone, I just posted another question asking what did "DD" mean in the post I have been reading. Sorry, but this confuses me because I thought what we had was a syndrome and not classified as a disease????? I have read that a Disease is a condition with a clearly identified cause. A Syndrome refers to a set of symptoms which define a condition but there is not a proven cause. I would like anyone else to share their personal opinion on this if you like.
