What is true about Rheumatoid Arthritis?

Rheumatoid Arthritis (RA) is a chronic inflammatory disorder that primarily affects the joints, leading to various symptoms and complications. One of the hallmark features of RA is its potential to cause joint deformities over time due to prolonged inflammation. The inflammation results in damage to cartilage and bone, which can lead to misalignment and deformities in the affected joints.

Individuals with rheumatoid arthritis may experience swelling, pain, and stiffness, which could progress to severe joint malfunction and deformity if the disease is not effectively managed. This characteristic sets RA apart from other forms of arthritis and speaks to the importance of early diagnosis and appropriate treatment to mitigate these long-term effects.

The other options do not accurately reflect the nature of RA. It is not limited to older adults, as it can affect people of any age, even children. Genetic factors play a significant role in the susceptibility to RA, making genetics a relevant consideration in its pathogenesis. Additionally, RA is not considered a rare disease; it is quite common, impacting a substantial portion of the population.
