Psoriasis


Not a rare disease Not a rare disease

Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. The skin on the elbows, knees, scalp, back, face, palms and feet is most often affected, but other parts of the body can be affected as well. A problem with the immune system causes psoriasis. In a process called cell turnover, skin cells that grow deep in the skin rise to the surface. Normally, this takes a month. In psoriasis, it happens in just days because the cells rise too fast. Although symptoms may come and go, for many, psoriasis is a lifelong condition. Infections, stress, dry skin and certain medications may make symptoms worse. Psoriasis usually occurs in adults. It sometimes runs in families. Treatments include creams, medications and light therapy.[1][2]

Research helps us better understand diseases and can lead to advances in diagnosis and treatment. This section provides resources to help you learn about medical research and ways to get involved.

Clinical Research Resources

  • ClinicalTrials.gov lists trials that are related to Psoriasis. Click on the link to go to ClinicalTrials.gov to read descriptions of these studies.

    Please note: Studies listed on the ClinicalTrials.gov website are listed for informational purposes only; being listed does not reflect an endorsement by GARD or the NIH. We strongly recommend that you talk with a trusted healthcare provider before choosing to participate in any clinical study.

Patient Registry

  • The Autoimmune Registry supports research for Psoriasis by collecting information about patients with this and other autoimmune diseases. You can join the registry to share your information with researchers and receive updates about participating in new research studies. Learn more about registries.

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
