Cause of Psoriasis
There are many different theories as to the cause of psoriasis. Although no one knows for sure, many scientists believe that a biochemical stimulus triggers the abnormally high skin growth which will in turn cause the skin lesions (National Psoriasis Foundation).
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 the disease (Camisa 55).
Recent research studies indicate that psoriasis may be a disorder of the immune system. The T cell, a white blood cell, normally works to fight off infection and disease. Scientists believe that having an abnormal immune system may 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 are thought to play a role in psoriasis development and progression (Kligman 729).
Because psoriasis is a lifelong condition, the levels of its severity and improvement can fluctuate over time. Psoriasis is not a contagious skin condition. An individual instead, has a genetic predisposition for psoriasis, which can be activated by certain environmental factors or emotional stress.
Individuals with psoriasis may find that their condition tends to flare up due to stress, certain medications, winter weather, and infections (ICN Pharmaceuticals, Inc.). Most often psoriasis affects the scalp, knees, elbows, hands, and feet (National Psoriasis Foundation).
