What is Psoriasis?

Psoriasis (PsO for short) is a chronic (long-term) inflammatory condition that usually starts in adulthood. If you have psoriasis, you’re in the company of one million Canadians who share this condition.

Not Just a Skin Condition

Contrary to the common misconception, psoriasis is not just a cosmetic inconvenience that goes only skin-deep. We now know that psoriasis is an autoimmune disease (an illness that occurs when the body tissues are attacked by its own immune system). The disease creates inflammation of the skin, but also in other areas of the body, including the joints (psoriatic arthritis).

Plaque psoriasis is the most common type of psoriasis. In this type, skin lesions, called plaques, cause itchy, scaly or flaky skin along with pain. It varies in severity from mild to moderate to severe, usually determined by the percentage of body area affected. The severity of psoriasis can be determined by a PASI score.

“We also now know that psoriasis is associated with many other conditions (known as comorbidities), including psoriatic arthritis, depression, diabetes, among others.”
