Psoriasis is a type of disorder that affects the joints and the skin. A person affected by this disorder has patches on the skin. It also results in skin inflammation as well as excessive skin production. Knees and the elbows are the common areas that are mostly affected by psoriasis. Scalp and genitals are also among the areas commonly affected by psoriasis.
There are several types of psoriasis. The classification is done on the basis of the symptoms. Some among these variants of psoriasis are plaque psoriasis, flexural psoriasis, guttate psoriasis, pusatular psoriasis, nail psoriasis and erythrodermic psoriasis. There is also another type of psoriasis, called psoriasis arthritis. The categorization of the types of this disorder is based mainly on the affected areas of the body.
What are the causes of Psoriasis?
Heredity is one of the important factors. If any of the parents is affected by psoriasis, there are 15% chances for the baby being affected by psoriasis. Any bruise, blister, cut or burn on the skin may also result in psoriasis. Throat infections have also been found to have caused this disorder in some cases. Smoking and addiction to alcohol are also among the common causes of psoriasis. What is even more extraordinary is that psychological trauma or mental stress is also among the causes of psoriasis.
How can Psoriasis be diagnosed?
The diagnosis of psoriasis depends on the appearance on the skin. There is hardly any diagnosis measure or some kind of blood test for diagnosing psoriasis. Skin scraping and skin biopsies are sometimes done in order to rule out the possibility of any other disorder so that it can be confirmed if it is psoriasis. If some pinpoint bleeding from the skin can be seen after the plaques are scraped, it is thought to be a sign of psoriasis.
The severity of psoriasis is based on the area of the body that has been affected. If 3% of the body is affected by psoriasis, it is graded as mild Psoriasis while affectation of 3% to 10% of the body will grade the disorder as moderate psoriasis. If the area of the body affected by Psoriasis is more than 10%, it is graded as severe psoriasis.
So far as the treatment options for psoriasis are concerned, there is no one treatment option for psoriasis. The dermatologists often resort to the try and error method in order to find out the most appropriate medicine for the particular patient.

Therapies with greater toxicity are effective for treating psoriasis.
