Assessing the Role of Stressful Life Events in the Induction and Recurrence of Alopecia Areata: A Case-Control Study

This case-control study investigates the association between stressful life events (SLEs) and the development or recurrence of alopecia areata (AA). The study highlights that AA is influenced by a combination of genetic, immunological, and environmental factors, with the role of psychological stress being particularly controversial. The research suggests that stress, which activates the hypothalamic-pituitary-adrenal axis, may inhibit hair growth and exacerbate AA. Additionally, the study notes a high lifetime prevalence (up to 74%) of psychiatric comorbidities among AA patients, indicating a significant psychosocial impact. The findings underscore the need to consider psychological factors in the management of AA.
