Alopecia areata: A psychodermatological perspective

Alopecia Areata (AA) is an autoimmune dermatological disease that could be influenced by psychological factors as part of the pathophysiology of the illness.

This review article aims to report on psychodermatological and psychopathological aspects involved in the etiopathogenesis and comorbidities of AA, as well as on the psychiatric and psychological management of affected patients.

We conducted a literature search on PubMed and Google Scholar from January 1980 to May 2021 employing the search terms of alopecia areata, psychological factors, psychological impact, psychodermatology, and psychopathology. All lists of references from the identified articles were screened for further relevant studies. The search was limited to English and Spanish language articles and was supplemented with themed books and book chapters. No specific quality criteria were used for the studies selection.

Several authors have found a high comorbidity rate between AA and mental disorders, concluding that stress and psychological factors are involved in both the development and exacerbation of the illness. More evidences are needed in order to describe the associations between the immune response, stress, and the physiological factors observed in AA patients.

AA is a complex illness characterized by multifactorial etiology. An interaction between genetic, autoimmune, hormonal, neural, and psychological factors is supposed. Psychopathological aspects of illness need to be better described and considered in the clinical setting.
