Causes
The cause of psoriasis is unclear. Signals from a defect in the immune system may result in an overgrowth of skin cells. Because the cells grow faster than they can be shed, they "pile up" on the skin's surface. The excess skin cells are thought to cause the silvery white scales that are characteristic of plaque-type psoriasis.
Risk Factors
A risk factor is something that increases your chance of getting a disease or condition.
- Family history of psoriasis
- Cold climates
- Suppression of the immune system, including AIDS
- Certain bacterial infections
- Certain medications, such as beta blockers and lithium
