Rheumatoid arthritis (RA) is a type of arthritis that occurs commonly in adults. But it is found that this condition can also develop in children and is known as juvenile rheumatoid arthritis. It is found in children aged 16 or younger. Juvenile RA or pediatric rheumatology is characterized by the inflammation of the synovium, which is the tissue that lines the inside of your joints.
Juvenile RA is a kind of autoimmune disease. It occurs when your immune system, which protects your body from the attack of foreign substances, attacks your own tissues. This condition is idiopathic, hence, the exact cause for the development of this disease is still unknown. Researchers believe that juvenile RA is related to different factors including genetics, environmental triggers and certain infections.
Juvenile rheumatoid arthritis can affect the joints and can cause inflammation, soreness, warmth, and swelling. It can affect any joint and can reduce the mobility of the affected joints.
