JIA is an autoimmune, noninfective, inflammatory joint disease, the cause of which remains poorly understood. It is characterised by chronic joint inflammation. JIA is a subset of childhood arthritis, but unlike other, more transient forms of childhood arthritis, JIA persists for at least six weeks, and in some children is a lifelong condition. It differs significantly from forms of arthritis commonly seen in adults ([osteoarthritis](https://en.wikipedia.org/wiki/Osteoarthritis), [rheumatoid arthritis](https://en.wikipedia.org/wiki/Rheumatoid_arthritis)), in terms of cause, disease associations, and prognosis.

The prognosis for children with JIA has improved dramatically over recent decades, particularly with the introduction of biological therapies and a shift towards more aggressive treatment strategies. JIA treatment aims for normal physical and psychosocial functioning, which is an achievable goal for some children with this condition.\[\\
