Psoriasis [pronounced sore-EYE-ah-sis] is a noncontagious, lifelong skin disease and affects both sexes equally and can occur at any age, although it most commonly appears for the first time between the ages of 15 and 25 years. It is probably one of the longest known illnesses of humans and simultaneously one of the most misunderstood and is usually graded as mild (affecting less than 3% of the body), moderate (affecting 3-10% of the body) or severe. Psoriasis can also cause inflammation of the joints, which is known as psoriatic arthritis and has been shown to affect health-related quality of life to an extent similar to the effects of other chronic diseases such as depression, myocardial infarction, hypertension, congestive heart failure or type 2 diabetes.
While it does get worse over time; It is not possible to predict who will go on to develop extensive psoriasis or those in whom the disease may appear to vanish. Research continues to accelerate at a rapid pace and will continue to advance our knowledge of what causes this disease.
Research shows that the signs and symptoms of psoriasis usually appear between 15 and 35 years of age and often disappear (go into remission), even without treatment, and then return (flare up). Controlling the signs and symptoms typically requires life long therapy. Symptoms can vary from person to person but may include one or more of the following: Red patches of skin covered with silvery scales, Small scaling spots (commonly seen in children,), Dry, cracked skin that may bleed, Itching, burning or soreness , Thickened, pitted or ridged nails, Swollen and stiff joints. Additional symptoms may include: Genital lesions in males, Joint pain or aching (psoriatic arthritis), Nail changes, including yellow-brown spots, dents (pits) on the nail surface, and separation of the nail from the base. About 10 percent of people with psoriasis have joint inflammation that produces symptoms of arthritis.
Most report a decrease in illness severity during the summer months or periods of increased sun exposure; however, a small minority find that their symptoms are aggravated by strong sunlight, and these individuals actually experience a worsening of their disease in the summer. Call your health care provider if you have symptoms or if the skin irritation continues despite treatment.
There are many treatments available that work wonders for one victim but have no effect or benefit for another. They range from local (cortisone cream application, emollients, coal tar, anthralin preparations, and sun exposure) to systemic (internal medications, including methotrexate and cyclosporine). As a first step, medicated ointments or creams, called topical treatments, are applied to the skin. Treatments for more general or advanced psoriasis include UV-A light, psoralen plus UV-A light (PUVA), retinoids (eg, isotretinoin [Accutane], acitretin [Soriatane]), infliximab (Remicade), etanercept (Enbrel), and alefacept (Amevive).

Additionally, a survey conducted by the Foundation in 2002 indicates that 26% of people living with moderate to severe psoriasis have been forced to change or discontinue their normal daily activities. The Foundation estimates that between 10% to 30% of The affected people also have psoriatic arthritis. Internationally, plaque psoriasis is universal in its occurrence and varies with race, geography, and environmental factors (eg, sun exposure).
