There is some overlap between psoriasis and PsA. However, not everyone with psoriasis will develop PsA. Keep reading to learn more about PsA without psoriasis, symptoms of both conditions, risk factors, treatment, and more. PsA and psoriasis are both chronic conditions, meaning they affect people long term, producing persistent symptoms that may come and go over time.
PsA is an inflammatory condition affecting the joints and the sites where tendons and ligaments attach to bone. Conversely, psoriasis is an immune-mediated skin condition that has no apparent cause.
The main component of psoriasis is inflammation due to an immune system irregularity. People with psoriasis may notice visible signs of inflammation, including raised plaques and scales on the skin.
The symptoms appear because the immune system is overactive and speeds up skin cell growth. Instead of natural shedding, the skin cells in people with psoriasis accumulate on the skin. Plaques and scales characteristic of psoriasis most commonly appear on the elbows, knees, and scalp, but they can develop anywhere on the body.
Although PsA and psoriasis have some genetic similarities, scientists do not fully understand the association between the two conditions. People can have PsA with no signs of psoriasis, but in most individuals , psoriasis precedes the arthritic symptoms. People can also have psoriasis without PsA. In the majority of cases, PsA appears 10 years after the development of psoriasis. While most people with PsA have psoriasis first, some can develop psoriasis after PsA.
According to the Arthritis Foundation , while people with PsA are less likely never to develop psoriasis, it is possible. PsA can develop slowly with mild symptoms or quickly with severe symptoms. It can occur following an injury to a joint, but it can also be genetic. Some common symptoms of PsA include :. Symptoms of psoriasis depend on the type of the condition, severity, and location on the body.
Common symptoms include :. People with psoriasis experience flares, during which symptoms worsen, as well as periods of remission, when symptoms go away or ease off.
Factors that can aggravate psoriasis include infections, dry skin , stress , and certain medicines. The National Psoriasis Foundation NPF states that while PsA often manifests between the ages of 30 and 50 , it can develop at any age, including in childhood.
According to the American College of Rheumatology, the risk of developing PsA is the same for women and men. Symptoms of psoriasis often begin between the ages of 15 and 25 , but they can start occurring at any age. However, prevalence of the condition varies based on country and age, which suggests that genetics, ethnicity, and environmental factors may increase the risk of developing psoriasis. Other risk factors for psoriasis include :. With early diagnosis, your doctor can treat your symptoms and slow the progression of the disease.
