What is psoriasis?

Psoriasis is a disease whose main symptom is gray or silvery flaky patches on the skin which are red and inflamed underneath when scratched. In the United States, it affects 2 to 2.6 percent of the population, or between 5.8 and 7.5 million people. Commonly affected areas include the scalp, elbows, knees, navel, palms, ears and groin. Psoriasis is autoimmune

in origin, and is not contagious. Around a quarter of people with psoriasis also suffer from psoriatic arthritis, which is similar to rheumatoid arthritis in its effects.

Psoriasis commonly occurs on pressure points such as the elbows, knees, and knuckles, as well as on the scalp, the trunk, the arms and legs, the external sex organs, and the fingernails and toenails. The severity of psoriasis varies widely. The most common pattern is for the disease to be limited to certain parts of the body but to recur (come back) frequently. Once someone has had a flare-up of psoriasis, the chances are nine out of 10 that the disease will recur. Psoriasis that begins earlier in life tends to be more severe and persistent. Usually people with psoriasis are otherwise healthy and feel well. However, if psoriasis affects large areas of the skin, it can seriously interfere with a person's ability to function normally. The thick, flaky patches of skin are often disfiguring and can be itchy or painful. If the hands or feet are affected, a person may have difficulty walking or holding a job. Caring for psoriasis is a daily, time-consuming process.

Psoriasis is an unpredictable condition that can sometimes flare up for no apparent reason. The course of the disease can be different in every individual who has it. People with psoriasis commonly go through periods of embarrassment, frustration, and depression about their condition. Because psoriasis affects exposed skin, it is a highly visible disease

When psoriasis develops, patches of skin thicken, redden, and become covered with silvery scales. These patches are sometimes referred to as plaques. They may itch or burn. The skin at joints may crack. Psoriasis most often occurs on the elbows, knees, scalp, lower back, face, palms, and soles of the feet. The disease also may affect the fingernails, toenails, and the soft tissues inside the mouth and genitalia. About 10 percent of people with psoriasis have joint inflammation that produces symptoms of arthritis. This condition is called psoriatic arthritis.
