Several factors can increase your risk of psoriatic arthritis, including:

  • Psoriasis. Having psoriasis is the single greatest risk factor for developing psoriatic arthritis. People who have psoriasis lesions on their nails are especially likely to develop psoriatic arthritis.
  • Your family history. Many people with psoriatic arthritis have a parent or a sibling with the disease.
  • Your age. Although anyone can develop psoriatic arthritis, it occurs most often in adults between the ages of 30 and 50.
