The key to sucessfully treating psoriasis is understanding the cause of psoriasis. It is believed that a biochemical stimulus triggers a faster skin growth. The body can't keep up with this accelerated rate of growth and as a result patches of raised skin accumulate.
Research shows that heredity also plays a role in the development of psoriasis. Individuals who have a family member with a severe case of psoriasis tend to experience early onset of symptoms of the disease.
Recent research studies indicate that a disorder within the immune system may also contribute to psoriasis. The T cell, a white blood cell, normally works to fight off infection and disease. Scientists believe that having an abnormal immune system can cause abnormal activity by T cells in the skin. These abnormally active T cells cause skin inflammation and increased cell production.
Diet and vitamin influences have also been thought to play a role in the cause of the development and progression if this condition.
