Who suffers from psoriasis?
Psoriasis affects 2 to 4% of the world population, estimated at 300 000 the number of patients in Portugal. Men and women are equally affected, even though there may be differences between racial groups. You can start at any age - even in childhood - but it has peaks of occurrence between 15-25 years and 50-60 years. Tends to persist throughout life, with periods of worsening and improvement. It is a disease of genetic basis is not possible to identify families affected in approximately one third of patients.
What causes psoriasis?
Psoriasis is a multifactorial disease in which genetic immunological factors, the environment also contributes to its appearance.
Immune System – The skin has different layers. The more superficial is the epidermis is formed by cells that are in constant division and that eventually die, covering the entire body surface with a film of dead cells called the stratum corneum. Every day, to the extent that the epidermal cells die and become part of the stratum corneum stratum, some cells that are also released, preventing the horny layer becomes too thick. The middle layer of the skin is the dermis where are the collagen and blood vessels. The most profound is the subcutaneous tissue (hypodermis) which is basically a layer of fat.
Genetics – The genetic factors are very important in the development of psoriasis: the genetic profile of the individual influences the type of psoriasis and response to treatment. There is however no genetic test that can diagnose or determine if an individual will develop the disease.
Environmental factors –Some stimuli may increase the risk of developing or worsening psoriasis as the physical stress, psychological stress, infections by bacteria or viruses, drugs (anti-hypertensives, anti-inflammatory, anti-malarial, among others) and smoking.
Psoriasis is not contagious, so it is not a disease that you can "catch" of other people, or "having" to other people. The lesions of psoriasis are not infectious.

How to diagnose psoriasis?
There is no analysis of blood or specific test to diagnose the disease. The dermatologist usually needs only to observe the skin surface to determine if it is psoriasis. When there is doubt, it may be necessary to remove a small piece of skin (skin biopsy) to be observed under microscope. Family history can contribute to the diagnosis.
