Psoriasis is a chronic disease in which cells rapidly build up on the skin. Many types of psoriasis exist, and plaque psoriasis is its most common form. According to the National Psoriasis Foundation, 2.2 percent of people in the United States suffer from psoriasis.
Symptoms
According to the Mayo Clinic, symptoms of plaque psoriasis include dry, red-raised skin lesions that are covered with silvery scales. The plaques are either painful or itchy and can occur anywhere in your body.
Cause
The cause of plaque psoriasis is unknown. However, stress, skin injuries and certain medications can trigger psoriasis flareups, according to the National Psoriasis Foundation.
Complications
According to the Mayo Clinic, plaque psoriasis can lead to all sorts of complications from bacterial infections and electrolyte (nutrients in the body) imbalances to depression, low self-esteem and anxiety.
Diagnosis
According to the National Psoriasis Foundation, there are no blood tests or diagnostic tools to determine whether you have plaque psoriasis. A dermatologist can examine and take a sample of your skin to determine whether it is plaque psoriasis.
Treatment
Treatments for psoriasis include creams placed on your skin to reduce inflammation, light therapy to kill T-cells responsible for attacking your skin and medications, such as methotrexate, that decrease skin cell production.
