So what's the difference between those two?

I know, it can be very confusing.

First of all, people, when they hear that kids can get arthritis, are like, ooh, is that a thing? Absolutely, kids can get arthritis.

And it used to be called juvenile rheumatoid arthritis.

Then I forget when this happened, probably about 20 years ago, 15, 20 years ago, they changed the name to juvenile idiopathic arthritis because they realized that kids don't necessarily look the same as adult RA patients.

And the I, idiopathic, just means that, well, kids get it, but we don't know exactly what causes it.

It's just the right setup of genes and environment.

And besides medications, what else do you use in your clinic to help with the patients?
