**4.6 Alopecia and personality profiles**

Patients with alopecia areata have a characteristic personality profile with low novelty seeking, low reward dependence, and low self-transcendence [76]. More withdrawn, depressive, and aggressive features are found in approximately 40–50% of children with alopecia areata [77]. There are not many studies on the personality traits of these patients, and the incidence of personality disorders in this group has not been studied either. There is a study documenting high depression, psychosthenia, and social introversion subscales in the Minnesota Multidimensional Personality Inventory (MMPI) assessment in this group [78]. Carrizosa et al. used the Minnesota Multidimensional Personality Inventory to show that patients with alopecia areata expressed more depressed, hysterical, and anxious feelings than healthy subjects [79].
