In the UK around 1 in 50 people have psoriasis and about 1 in 200 will have psoriatic arthritis. Both conditions are long-term and can get worse over time, though treatments can relieve the symptoms and slow down disease progression. Although much is known about psoriatic disease, more research is needed. By supporting us you can help us in our goal to help people affected by psoriatic disease to have appropriate care to understand the causes and eventually find a cure. PAPAA website
