The most common form of juvenile (affecting children)&nbsp;arthritis is <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/jra.html/">juvenile idiopathic arthritis (JIA)</a>.</p> <p><img title="illustration" src="https://kidshealth.org/EN/images/illustrations/jia-415x233-enIL.png" alt="arthritis illustration" name="4793-JIA_A_ENIL.PNG" /></p> <h3>More to Know</h3> <p>Causes of JIA are not known ("idiopathic" is a medical term used to describe a disease with no known cause). But experts believe&nbsp;it's an autoimmune disease (when the body's <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/immune.html/">immune system</a> isn't working correctly).</p> <p>There are seven major types of JIA, and they&nbsp;usually affect kids and teens&nbsp;between 6 months and 16 years old. The first signs can include limping or a sore wrist, finger, or knee. <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/bones-muscles-joints.html/">Joints</a> may suddenly swell and remain enlarged. Stiffness in the neck, hips, or other joints also can occur.</p> <p>JIA is a chronic condition, meaning it can last for months and years. Sometimes the symptoms go away on their own (called remission). Remission may last for months, years, or a person's lifetime.</p> <h3>Keep in Mind</h3> <p>An early and accurate diagnosis is key to effectively managing JIA. Understanding the symptoms and characteristics of each type of JIA can help a person&nbsp;maintain an active, productive lifestyle.</p> <p>Medications might be used for pain and inflammation or to aid the immune system, and physical therapy and exercise sometimes help. Rarely, a person might need surgery or corticosteroid injections.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
