Psoriasis Causes, Symptoms and Treatments

Psoriasis greatly affects the lifecycle of the skin cells and is a commonly viewed disease. Under normal circumstances, the new cells take around 30 days to gradually shift from the lowest layer of the skin to the uppermost layer where they become useless and flake off. In the case of psoriasis the complete cycle of the formation of new cells and the flaking off takes just a few days, it is so rapid that the cells buildup in matter of time form thick crusty scales that are silvery in appearance and sometimes also get dry, itchy and painfully red. Unfortunately psoriasis is long suffering and chronic. In the early stages psoriasis can be quite an annoyance while for others as the disease progresses it can get quite incapacitating especially if the individual is also suffering from arthritis. Psoriasis has no cure but the symptoms and flaking can be managed with the help of a combination of treatments. Most therapies offer substantial belief from the itching and the soreness especially if there is a good combination of personal care and exposing the affected skin to ultraviolet light.

In almost cases of psoriasis there are phases of this condition. The symptoms flare up for a few weeks and then disappear for a time. Sometimes these symptoms go into complete remission but in most cases the disorder finally comes back. There are different types of psoriases. Plaque psoriasis, nail psoriasis, scalp psoriasis, guttate psoriasis, inverse psoriasis, pustular psoriasis, erythrodermic psoriasis, and psoriatic arthritis. The immune system is largely blamed for this disorder and to pinpoint the problem within the immune system, the fault lies with the T lymphocyte or T cell. T cells are known to travel around the body to try and discover if there are foreign cells in the body and to attack and destroy them. in the case of psoriasis T cells begin attacking healthy cells as they perceive healthy cells as the cause of an infection or a wound.

The T cells start acting in an aggressive manner and activate other immune responses thus bringing about a rapid increase in both, the growth of T cells as well healthy cells. Hence there ensues an ongoing battle. Since dead cells are unable to scour off the surface easily they tend to pile up in thick crusts and buildup the scaly appearance. The cycle will continue unless medication interferes in this process. But it is still not known why T cells develop a mistaken identity towards the healthy cells. Some analysts are of the belief that genes as well as environmental factors play an equal role.
