Psoriatic Arthritis

Psoriatic arthritis (PsA) is a type of chronic inflammatory arthritis associated with the chronic skin condition psoriasis, which is believed to be an inherited condition. Psoriasis, which affects about 2 percent of the U.S. population, most often causes patches of thick, reddened, irritated skin with flaky, silver-white patches called scales.

Psoriatic arthritis typically appears about 10 years after the onset of psoriasis, which can manifest at any age, though most people are diagnosed between the ages of 15 and 35. There are five types of psoriatic arthritis, each with similar but distinctive symptoms. There is no cure for psoriatic arthritis. The goal of treatment is to reduce joint pain and swelling, preserve joint function, slow or prevent joint damage and control psoriasis on the skin.
