What will it take for childhood trauma research to change paradigms?

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?

Sex-specific impacts of childhood trauma

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

Your need to feel important will run your life, and you’ll never feel satisfied

gettingwell4 5+ stars, Memory, Primal Therapy , , , ,

Yesterday’s team meeting at work provided one display after another of a person’s need to feel important. These eye-openers were the reason the scheduled 30-minute meeting lasted 45 minutes. Although half of the forty or so attendees are under the age of 40, curiously, only two of them spoke during the meeting. I wasn’t among … Continue reading Your need to feel important will run your life, and you’ll never feel satisfied

An emotional center of our brains

This 2018 McGill/UC San Diego rodent study was on the dentate gyrus area of the hippocampus: “Early life experience influences stress reactivity and mental health through effects on cognitive-emotional functions that are, in part, linked to gene expression in the dorsal and ventral hippocampus. The hippocampal dentate gyrus (DG) is a major site for experience-dependent … Continue reading An emotional center of our brains

DNA methylation and childhood adversity

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 pain societies instill into children

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

Most of the spam I get on this blog comes in as ersatz comments on The hypothalamus couples with the brainstem to cause migraines. I don’t know what it is about the post that attracts internet bots. The unwanted attention is too bad because the post represents a good personal illustration of “changes in the … Continue reading How to cure the ultimate causes of migraines?

What is a father’s role in epigenetic inheritance?

The agenda of this 2017 Danish review was to establish a paternal role in intergenerational and transgenerational epigenetic inheritance of metabolic diseases: “There are four windows of susceptibility which have major importance for epigenetic inheritance of acquired paternal epigenetic changes: paternal primordial germ cell (PGC) development, prospermatogonia stages, spermatogenesis, and during preimplantation.” The review was … Continue reading What is a father’s role in epigenetic inheritance?

Does a societal mandate cause DNA methylation?

gettingwell4 2-3 stars, Epigenetics

This 2017 worldwide meta-analysis of humans of recent European ancestry found: “Here we provide evidence on the associations between epigenetic modifications-in our case, CpG methylation and educational attainment (EA), a biologically distal environmental factor that is arguably among the most important life-shaping experiences for individuals. Specifically, we report the results of an epigenome-wide association study [EWAS] … Continue reading Does a societal mandate cause DNA methylation?

Do preventive interventions for children of mentally ill parents work?

gettingwell4 < 0, Beliefs, Cerebrum, Epigenetics

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?
