The Impact of Psoriasis on Quality of Life

Psoriasis is a chronic inflammatory skin disease in which the signs vary from one patient to another and over time. Traditionally, physicians have used various parameters to assess the severity of the disease: percentage of body surface area covered, erythema, plaque thickness, degree of scaling and systemic symptoms such as arthritis. However, these clinical assessments alone do not accurately reflect the overall effect of the disease on patients' daily activities. Apart from the clinical severity of affected areas, psoriasis can also have a profound psychosocial impact on the patient's quality of life. This concept is multidimensional, encompassing the physical, social and psychological wellbeing of the person and is based on the patient's view of their condition.
