"Arthritis is common, and rheumatoid arthritis often gets confused with the other kinds of arthritis in people's minds,” he says.
Plus, rheumatoid arthritis is still mysterious in many ways. Research and new treatments are constantly changing the understanding of the disease.
Even the experts still have a lot to learn about rheumatoid arthritis. WebMD teamed up with Kremer to explode a few common myths about this "commonly unusual" disease.
Myth No. 1: Rheumatoid arthritis is just like ‘regular arthritis.’
Fact: Rheumatoid arthritis is not "regular arthritis." What we think of as “regular arthritis” is osteoarthritis, caused by injury or normal wear-and-tear on aging joints. Osteoarthritis is the most common joint disease in middle age to older people.
By contrast, rheumatoid arthritis is a chronic, progressive autoimmune disorder. In response to an unknown trigger, the body makes antibodies that attack its own tissues. The self-attacks mostly affect the joints, although they can also affect other body parts. Disease attacks, called flare-ups, occur periodically, or can be continuous in some people.
"This is the most common confusion -- between osteoarthritis and rheumatoid arthritis. It gets even more confusing, because people with RA often also have osteoarthritis," adds Kremer.
Myth No. 2: Only old people get rheumatoid arthritis.
Fact: In most people who develop RA, the disease starts between the ages of 30 and 55.
"This is the peak age group," says Kremer, "but anyone can get rheumatoid arthritis, even teenagers." At the same time, "older folks may have more severe RA, because it's progressive and they've been living with it longer."
