Psoriasis affects about 4% of the world population. It can develop at any age, from birth until old age, but most of all the psoriasis "loves" the young. This is demonstrated by the fact that 70% of the patients, suffering from psoriasis at the age of 20 years.
If the rash has appeared, similar to psoriasis – it is necessary to consult a dermatologist. Skin rashes are an itchy peeling of the plate of various sizes. When platelets in psoriasis can be located on the elbows, knees, scalp, or other parts of the body. The doctor can provide an accurate diagnosis and, depending on its form, to prescribe a treatment.
Psoriasis is an abnormal reaction of the organism to external stimuli, for which in some areas of the body the upper layer of the skin dies a lot faster than normal. If you usually cycle, division and maturation of cells of the skin occurs for 3-4 weeks, then for the psoriasis, this process happens in just 4-5 days.
Currently psoriasis believe hereditary multifactorialnyh of the disease: the disease is not one but a series of reasons – immunological shifts, metabolic disorders, endocrine and neurological disorders. In this case we can say with certainty: psoriasis is not contagious, so it is not a contagious disease.
The causes of psoriasis are not yet finally found. There are various theories.
According to one theory, there are two types of psoriasis:• Psoriasis type I is called transferred to successive failures of the immune system. This form of psoriasis affects about 65% of the people, and the disease manifests at a young age, from 18 to 25 years.
According to another theory, the cause of psoriasis are only the violations of the immune system caused by various factors: it can be stress or infectious diseases, or cold climate, or the wrong food. For example, observed that alcohol can cause a worsening of psoriasis — this applies especially to beer, champagne, strong alcoholic drinks. The use of products containing vinegar, pepper, chocolate, and also worsens the course of disease and can cause a worsening of psoriasis. According to this theory, psoriasis is a systemic disease. This means that in the event of serious irregularities in the functioning of the immune system, the process can spread to other organs and tissues, for example, on the joints. The result can develop psoriatricheskii arthritis, which is characterized by a defeat in the small joints of the hands and feet.
The symptoms of psoriasis are inflamed, flaking patches of red color, accompanied by severe itching. These spots (platelets) are most often found on the scalp, knees, and elbow joints, in the lower part of the back and in the places of the folds of the skin .

Skin rashes are usually accompanied by flaking and painful itching. In the process of peeling of superficial scales are more narrow, are situated in the depth (hence the second name of psoriasis — bow zoster). Sometimes in the context of the affected areas cracks and suppuration.
For progressive psoriasis is characterized by the so-called phenomenon Kebnera: the development of plaques in places of injuries or abrasions of the skin.
About a fourth of the patients affected, the nails. When you experience points and spotting the nail plate. In addition, the nails can utolzhatsya and crumble.
In the summer, under the influence of the solar rays, in patients with winter form of psoriasis symptoms weaken, and sometimes even disappear completely.
