Over seven million men and women in the U.S. of all ages have some form of psoriasis, which may be mild, moderate or severe. The most commonly affected areas are the scalp, elbows, knees, hands, feet and genitals.
Psoriasis cannot be cured but it can be treated successfully with clearing of lesions sometimes for months or years at a time, and occasionally even permanently. Treatment depends on the type, severity and location of psoriasis, the patient’s age, medical history and lifestyle, and the effect the disease has on the patient’s general mental health. The most common treatments are topical medications, phototherapy, photochemotherapy (PUVA), and oral or injectable medication (for severe symptoms).
