Disease Fact Sheets
Each autoimmune and autoinflammatory arthritis ( Ai Arthritis) disease we cover has a fact sheet you can download and print. Most open right from this page.
Ai Arthritis is led by people living with Ai Arthritis diseases. Print one to bring to an appointment, or to help someone close to you understand what you're living with.

What's inside each fact sheet?
We know how it feels to explain a disease for the tenth time, often to someone who has never heard of it. A fact sheet does that explaining for you.
Each one covers the symptoms that tend to set its disease apart and how doctors reach a diagnosis. Most also show you how to say the name (Behçet's is buh-shehts), share the history behind the disease, and carry words from someone who lives with an Ai Arthritis disease.

Where do these fact sheets come from?
Every resource, guide, tool and program we have made started the same way. First we talked with fellow patients from around the world, and those conversations showed us what was needed to improve our journeys.
Our work is peer-led, so what you've lived through shapes what we build next.
What was missing from your fact sheet?
If something you live with isn't on the fact sheet you read, tell us. What you tell us goes into the next version, so the next person has more to go on.
