Childhood abuse and neglect are differentially related to perceived discrimination and structural change in empathy-related circuitry

ABSTRACT

Behavioral studies indicate that adverse childhood experiences (ACE) are associated with altered empathic responding, but the neural mechanisms underlying this relationship remain unclear. Given the significance of empathy in contexts marred by historical conflict and systemic inequality, work on these mechanisms is particularly important in such contexts. The current study extends previous work by (1) examining associations of different dimensions of ACE with volumetric change in empathy-related circuitry, (2) distinguishing between trait and state empathy, and (3) including perceived discrimination as an additional psychosocial stressor. Thirty-nine healthy South African adults from the general population (M_age = 40.6 years) underwent 3 T MRI. FreeSurfer v6.0 was used to extract predefined volumes subserving empathy. Results showed that childhood abuse and perceived discrimination were associated with reduced state empathic concern, whereas childhood neglect was associated with reduced trait cognitive empathy. Childhood abuse was furthermore associated with volumetric increases in frontolimbic (hippocampus, anterior cingulate cortex (ACC)) and neocortical (superior frontal and temporal) regions subserving affective and cognitive empathy, and uniquely mediated the relationship between ACC volume and perceived discrimination. The association of ACE with altered empathic responding may thus be underpinned by specific circuitry reflective of adversity type, with childhood abuse contributing to heightened responsivity to socioemotional cues.
