PsoriasisPsoriasisCauseThe exact cause of
psoriasis isn't known. Doctors believe that the
immune system overreacts, causing inflammation and flaking of skin. Many scientists believe that psoriasis can be inherited. About one-third of people who have psoriasis have one or more family members
with the condition.1 But it isn't clear that genetic
factors alone determine whether you get psoriasis. Psoriasis isn't
contagious—it can't be spread by touch from person to person. Medical Review: Adam Husney, MD - Family Medicine Amy McMichael, MD - Dermatology Last Updated: January 9, 2012 |
