The principal way science advances is through the principle Einstein expressed as: “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.” Members of the scientific community and of the public should be satisfied that the scientific process is working well when hypotheses are discarded due to nonconfirming evidence. … Continue reading A disturbance in the paradigm of child abuse
This 2018 German human study found: “DNA methylation in a biologically relevant region of NR3C1-1F [the glucocorticoid receptor gene] moderates the specific direction of HPA-axis dysregulation (hypo- vs. hyperreactivity) in adults exposed to moderate-severe CT [childhood trauma]. In contrast, unexposed and mildly-moderately exposed individuals displayed moderately sized cortisol stress responses irrespective of NR3C1-1F DNA methylation. … Continue reading What will it take for childhood trauma research to change paradigms?
This 2018 Canadian paper reviewed evidence for potential sex-specific differences in the lasting impacts of childhood trauma: “This paper will provide a contextualized summary of neuroendocrine, neuroimaging, and behavioral epigenetic studies on biological sex differences contributing to internalizing psychopathology, specifically posttraumatic stress disorder and depression, among adults with a history of childhood abuse. Given the … Continue reading Sex-specific impacts of childhood trauma
This 2017 Georgia human review covered: “Recent studies, primarily focused on the findings from human studies, to indicate the role of DNA methylation in the associations between childhood adversity and cardiometabolic disease in adulthood. In particular, we focused on DNA methylation modifications in genes regulating the hypothalamus-pituitary-adrenal axis as well as the immune system.” Recommendations … Continue reading DNA methylation and childhood adversity
The human subjects of this 2017 Swiss study had previously been intentionally traumatized by Swiss society: “Swiss former indentured child laborers (Verdingkinder) were removed as children from their families by the authorities due to different reasons (poverty, being born out of wedlock) and were placed to live and work on farms. This was a practice … Continue reading The pain societies instill into children
The fifth and final paper of Transgenerational epigenetic inheritance week was a 2017 German/Italian meta-analysis of psychiatric treatments involving human children: “The transgenerational transmission of mental disorders is one of the most significant causes of psychiatric morbidity. Several risk factors for children of parents with mental illness (COPMI) have been identified in numerous studies and meta-analyses. … Continue reading Do preventive interventions for children of mentally ill parents work?
Same old shit – another failed relationship. Coincident with the start of our relationship, I was struck by a phrase by Dr. Janov, posted in Beyond Belief: What we do instead of getting well: “It doesn’t matter about the facts we know if we cannot maintain a relationship with someone else.” I kept that thought … Continue reading Prisoners of our childhoods
This 2017 German human study explored the relationship between birth stress and handedness. The authors summarized previous research which, among other points, estimated epigenetic contributions to handedness as great as 75%. The research hypothesis itself was worthwhile based on the prior studies cited and elsewhere such as Is what’s true for a population what’s true for … Continue reading Parental lying thwarted both their children and researchers
This 2016 Swedish human study investigated the effects of one specific childhood trauma, parental death: “Parental (G1) death during (G2) childhood predicts prematurity and lower birthweight in the offspring generation (G3). This response is dependent on G2 gender, G2 age at exposure and G3 parity, but not on G3 gender. Offspring of women who lost … Continue reading Does childhood trauma influence offspring’s birth characteristics?
I ain’t got a heart of stone I’m hurting more now than I’ve ever known If you mean the things you said I’m gonna wind up out of my head Can’t sleep alone at night I just can’t seem to get it right Damned if I do Damned if I don’t But I love you … Continue reading Childhood
