What Is Scalp Psoriasis?
9. Prognosis
Although benign, psoriasis is a lifelong condition that has remissions and exacerbations. Some cases may be refractory to treatment and cause arthritis in 10% of psoriasis cases. Although mild psoriasis does not increase the risk of death, men with severe cases died 3.5 years earlier while women with severe cases died 4.4 years earlier than their average life expectancy.
A population-based cross-sectional study has also found that those with more extensive psoriatic skin disease have a higher risk of major medical comorbidities such as chronic lung disease, heart disease, blood vessel disease, joint issues, kidney disease, and diabetes. The risk of other serious illness was 11% higher for mild cases, 15% higher for moderate cases, and 35% higher in severe cases.
