What are some differences between juvenile rheumatoid arthritis (JRA) and adult arthritis?

ANSWER

The main difference between juvenile and adult arthritis is that some children with JRA outgrow the illness, and adults usually have lifelong symptoms. And unlike adult rheumatoid arthritis, JRA may affect bone development and the child's growth.

Also, 70%-80% of all adults with rheumatoid arthritis have rheumatoid factor in their blood, but less than half of children with rheumatoid arthritis do. The presence of rheumatoid factor means JRA is more likely to continue into adulthood.
