Intergenerational Trauma Transmission

AbstractIntergenerational trauma increases lifetime susceptibility to depression and other psychiatric disorders. Whether intergenerational trauma transmission is a consequence of in-utero neurodevelopmental disruptions versus early-life mother–infant interaction is unknown. Here, we demonstrate that trauma exposure during pregnancy induces in mouse offspring social deficits and depressive-like behavior. Normal pups raised by traumatized mothers exhibited similar behavioral deficits to those induced in pups raised by their biological traumatized mothers. Good caregiving by normal mothers did not reverse prenatal trauma-induced behaviors, indicating a two-hit stress mechanism comprising both in-utero abnormalities and early-life poor parenting. The behavioral deficits were associated with profound changes in the brain metabotranscriptome. Striking increases in the mitochondrial hypoxia marker and epigenetic modifier 2-hydroxyglutaric acid in the brains of neonates and adults exposed prenatally to trauma indicated mitochondrial dysfunction and epigenetic mechanisms. Bioinformatic analyses revealed stress- and hypoxia-response metabolic pathways in the neonates, which produced long-lasting alterations in mitochondrial energy metabolism and epigenetic processes (DNA and chromatin modifications). Most strikingly, early pharmacological interventions with acetyl-L-carnitine (ALCAR) supplementation produced long-lasting protection against intergenerational trauma-induced depression.

The Impact

In the growing field of colonial and anti-colonial research, many parallels have been drawn between Westernized countries including Australia and Canada. In both of these countries, there is considerable academic, community and governmental recognition of historic, and continuing, colonizing of Indigenous peoples and the subsequent impacts on Indigenous cultures. Terms such as transgenerational trauma and intergenerational trauma give language to the ongoing impact of colonization on communities, which in turn serves to legitimize the need for mental wellbeing supports and associated funding. However, there are other minority communities that are similarly oppressed and colonized but do not experience the same legitimization. One such community is the Deaf community. Deaf people continue to experience systemic oppression and colonization within our hearing centric society. Building on the work of Batterbury, Ladd and Gulliver (2007), we extend discussions on the parallels between Indigenous and Deaf communities of Australia and Canada, drawing on the established and commonly discussed link between the impact of racism and colonization on (mental) health. We connect these discussions to modern instances of colonization including the aspect of deaf education to illustrate a “living” mechanism through which colonization continues to impact mental wellbeing in the broader Deaf community.

Physical And Sexual Abuse

Historical trauma originated with the social construction of subordinate group statuses through migration, annexation of land, and colonialism. The consequences of creating subordinate group statuses include genocide, segregation, and assimilation. Settler colonialism takes land with militaristic control, labels local inhabitants as deviant and inferior, then violently confines and oppresses the original occupants of the land. Confinement includes relocation, restriction of movement, settlement of lands required for sustenance, as well as confinement in orphanages, boarding schools, and prisons. Historical trauma includes suppression of language, culture, and religion with the threat of emotional, physical, and sexual abuse. Original inhabitant abuse often results in issues with health, mental health, substance abuse, and generational emotional, physical, and sexual abuse. Culturally safe (engagement that respects identity) and trauma-informed social work practices acknowledge the systemic causes of disparities in groups experiencing marginalization and oppression and focus on healing and addressing systemic causes of disparities.
