Rheumatoid arthritis is a chronic, inflammatory type of arthritis. Rheumatoid arthritis is also classified as an autoimmune disease (immune cells attack the body's own healthy tissues). The joints are primarily affected by rheumatoid arthritis, but there can be systemic effects (i.e. organs) as well. Early diagnosis of rheumatoid arthritis and early, aggressive treatment can help prevent joint damage and deformity. Typically, disease onset for rheumatoid arthritis occurs between 30 and 60 years old.
