Psoriasis can be described as reoccurring condition of the skin characterised by reddish, scaly sections of inflammation. Psoriasis is normally observed on the arms, legs, trunk, nails, or scalp, but it can be located on any part of the skin. The most commonly affected areas are the knees and also elbows.

Psoriasis is an immune condition that impacts both males and females. Estimates vary but somewhere between 4.5 and 7.5 million people inside the U.S. have already been diagnosed with psoriasis. 150,000 new cases are diagnosed annually. Psoriasis isn't contagious. It is not something you can "catch" or that other people can catch from you. Psoriasis lesions aren't infectious.

Thick, scaly, red plaques would be the hallmark of psoriasis. In psoriatic skin, the cells belonging to the outer layer (epidermis) multiply too rapidly, which causes skin to thicken. Additionally, they adhere to one another more strongly and for longer than normal skin cells do, causing scaliness. The skin is infiltrated by white blood cells, causing inflammation, redness, and infrequently pustules.

Precisely why this happens is not yet well understood, but genetics are clearly involved. Ancestors and family history can affect who is diagnosed with psoriasis - if a parent has psoriasis, a child has a 10 percent chance of developing it as well. However, the appropriate psoriasis triggers must also exist before symptoms begin to appear.

Researchers now believe that there could be an ethnic link to Psoriasis, since it is most commonly encountered in Caucasians throughout the US and Northern Europe. In addition, genetics apparently plays a role. Studies have shown that one-third of those diagnosed with psoriasis have at least one near relative with the condition. A study conducted in the US found the incidence of psoriasis was 2.5% in Caucasians and 1.3% in African Americans.

Psoriasis could be mild or severe. When it's severe, it may adversely influence functions of daily lifestyle among them work and social activities.

There is as yet no total cure for psoriasis. Treating psoriasis will depend on its severity and location. Medical treatments vary from local (cortisone treatment application, emollients, coal tar, anthralin preparations, and exposure to the sun) to systemic (internal medicinal drugs, such as methotrexate and cyclosporine).

In addition, there are various natural and alternative medicine treatments based on psoriasis natural treatment that have proven to be effective. Every person with psoriasis is different. That which is the best psoriasis treatment for one may not do anything for another.
