I just came upon this interactive, multi-media glossary of lupus terms, provided by the Alliance for Lupus Research, and I think it's fabulous!
All too often, there's a lupus term that I think I know, but realize in the end, I really don't. I find the "Rule of Repetition" to be a good gauge here: if I can explain it to someone else, that means I understand it myself. If not, it's off to the glossary I go!
Check out ALR's Lupus glossary here, and let me know if you learn anything new!
