Divergent Amygdala Volume Asymmetries for Male and Female Youth With High Versus Low Callous-Unemotional Traits$d

Although callous-unemotional (CU) traits have been associated with amygdala hypoactivity, it is unclear whether such traits are associated with amygdala structure. This study examines the relationship between amygdala structure and CU traits and considers sex differences in hemisphere-related asymme...

520 |a Although callous-unemotional (CU) traits have been associated with amygdala hypoactivity, it is unclear whether such traits are associated with amygdala structure. This study examines the relationship between amygdala structure and CU traits and considers sex differences in hemisphere-related asymmetries in this relationship. In this brain imaging study of children (n = 272), a significant sex × hemisphere × CU traits interaction was observed. Females with high CU traits and males with low CU exhibited a rightward exaggerated amygdala volume asymmetry, whereas females with low CU traits and males with high CU traits did not. Findings may reflect sex-related influences related to CU traits and amygdala volume and are broadly consistent with a neurodevelopment perspective on psychopathic-like traits in children.
