The tool involves not only medical assessment, but also subjective symptom assessments reported by the subject. The index is divided into the following parts, which receives a numerical score: Extension (ares with AD lesions); Intensity of reactions (erythema, edema, exudation/crusts, abrasions, lichenification and dry skin; and Subjective Symptoms (pruritus and sleep loss). To evaluate these parameters, a scale from 0 to 10 is used. At the end, a global classification of AD is automatically attributed to each subject.
