This is very difficult to predict at the outset, and to some extent, it depends on the type of JIA. In a small number of children, the disease may last as little as several months to a year and disappear forever. Most children, however, have an up-and–down course with “flares” and “remissions” for many years with about half of them continuing to have problems into adulthood. While there is no cure for juvenile arthritis, current available therapy often prevents the long-term damage and disability that may be left by arthritis even after it has gone.
