Psoriasis
Effect on the Quality of Life:
Psoriasis is a disease whose main symptom
is gray or silvery flaky patches on the skin which are red and inflamed
underneath. 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, arms, stomach and back. 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 was first given that name in complete
differentiation from other skin conditions by the Austrian dermatologist
Ferdinand von Hebra in 1841, although there are what are believed to be descriptions
of the disease in sources going back to ancient Roman and possibly even
biblical times.
