What is psoriatic arthritis?
Psoriatic arthritis is a form of inflammatory arthritis that can affect some of the millions of Americans who have psoriasis. Psoriasis is a skin disease that causes a red, scaly rash, most commonly over the elbows, knees, ankles, feet, hands, and other areas.
Psoriatic arthritis may develop at any age, but usually affects people between the ages of 30 and 50. While the cause is not known, genetic factors, along with the immune system, likely play a role in determining who will develop the disorder.
