Notes:

1. Men and women develop psoriasis at equal rates.
2. Psoriasis also occurs in all racial groups, but at varying rates. (About 1.9 percent of African-Americans have psoriasis, compared to 3.6 percent of Caucasians).

Typical Age of onset

Psoriasis often develops between the ages of 15 and 35, but it can develop at any age. About 10 to 15 percent of those with psoriasis get it before age 10. Some infants have psoriasis, although this is considered rare.

Symptoms

  • Plaques of red, inflamed skin, often covered with loose, silver-colored scales.
  • Disorders of the fingernails and toenails (discoloration and pitting of the nails. The nails may also begin to crumble or detach from the nail bed.)
  • Scaly plaques on the scalp.
  • Small areas of bleeding where the involved skin is scratched.
