Psoriasis Severity Index

The Psoriasis Severity Index (PASI) is a clinical tool used by healthcare providers to measure how severe psoriasis is on a patient's skin. It considers the extent of the affected areas and the intensity of symptoms like redness, thickness, and scaling. The skin is divided into different regions, and each area's condition is scored based on these factors. The scores are then combined into a total value, providing an overall picture of disease severity. This helps doctors assess the progression of psoriasis and determine the most appropriate treatment plan.
