What are causes and risk factors of psoriasis?

The exact cause remains unknown. There may be a combination of risk factors, including genetic predisposition and environmental factors. It is common for psoriasis to be found in members of the same family. Defects in the immune system are thought to play a major role. Despite research over the past 30 years looking at many triggers, the "master switch" that turns on psoriasis is still a mystery.

Can psoriasis affect my joints?

Yes, psoriasis is associated with joint problems in about 10%-35% of patients. In fact, sometimes joint pains may be the only sign of the disorder with completely clear skin. The joint disease associated with psoriasis is referred to as psoriatic arthritis. Patients may have inflammation of any joints (arthritis), although the joints of the hands, knees, and ankles tend to be most commonly affected. Psoriatic arthritis is an inflammatory, destructive form of arthritis and is treated with medications to stop the disease progression. The average age for onset of psoriatic arthritis is 30-40 years of age. In most cases, the skin symptoms occur before the onset of the arthritis.

Can psoriasis affect only my nails?

Yes, psoriasis may involve solely the nails in a limited number of patients. Usually, the nail signs accompany the skin and arthritis symptoms. Nail psoriasis is typically very difficult to treat. Treatment options are somewhat limited and include potent topical steroids applied at the nail-base cuticle, injection of steroids at the nail-base cuticle, and oral or systemic medications as described below for the treatment of psoriasis.
