Juvenile Rheumatoid Arthritis (JRA) is a type of arthritis that affects children. It causes inflammation in the joints, leading to pain, swelling, and stiffness. JRA can impact a child's daily activities and overall quality of life. The exact cause of JRA is not known, but it is believed to involve an autoimmune response where the body's immune system mistakenly attacks its own tissues. There are several types of JRA, including oligoarticular, polyarticular, and systemic. Treatment typically involves medications to reduce inflammation and manage pain, as well as physical therapy to maintain joint function. Early diagnosis and intervention are crucial for better outcomes in affected children.
