Junior Psoriatic Arthritis

Juvenile psoriatic arthritis can be tricky to diagnose. While psoriasis is a common skin condition, associated primarily with a chronic rash all over the, only about 12 to 14 percent of people with psoriasis will develop related arthritis.CausesGenetic and environmental factors play a strong role in the development of psoriatic arthritis. A family history of psoriasis is linked to many children with juvenile psoriatic arthritis, as well as a family history of other forms of spondyloarthropathy. There is little relationship between the severity of a rash and the risk of getting juvenile psoriatic arthritis, however.NOTE: In some people with juvenile psoriatic arthritis, the arthritis shows up before the rash. In these cases, diagnosis can be so difficult that it may take up to 10 years to be certain of a definite diagnosis.Signs and Symptoms
