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?

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

A problematic study of oxytocin receptor gene methylation, childhood abuse, and psychiatric symptoms

This 2016 Georgia human study found: “A role for OXTR [oxytocin receptor gene] in understanding the influence of early environments on adult psychiatric symptoms. Data on 18 OXTR CpG sites, 44 single nucleotide polymorphisms, childhood abuse, and adult depression and anxiety symptoms were assessed in 393 African American adults. The Childhood Trauma Questionnaire (CTQ), a … Continue reading A problematic study of oxytocin receptor gene methylation, childhood abuse, and psychiatric symptoms

Is this science, or a PC agenda? Problematic research on childhood maltreatment and its effects

This 2013 Wisconsin human study’s goal was to assess effects of childhood trauma using both functional MRI scans and self-reported answers to a questionnaire. The families of the study’s subjects (64 18-year-olds) had been participating with researchers, possibly as early as 1990, which was before the teenagers were born. How could the teenagers give answers … Continue reading Is this science, or a PC agenda? Problematic research on childhood maltreatment and its effects

Early emotional experiences change our brains: Childhood maltreatment is associated with reduced volume in the hippocampus

This 2011 human study by the grandfather of hippocampus stress studies, Martin Teicher, quantified childhood maltreatment using the Adverse Childhood Experiences study and Childhood Trauma Questionnaire scores: “The strongest associations between maltreatment and volume were observed in the left CA2-CA3 and CA4-DG subfields, and were not mediated by histories of major depression or posttraumatic stress … Continue reading Early emotional experiences change our brains: Childhood maltreatment is associated with reduced volume in the hippocampus

Manufacturing PTSD evidence with machine learning

What would you do if you were a scientist who had strong beliefs that weren’t borne out by experimental evidence? Would you be honest with yourself about the roots of the beliefs? Would you attempt to discover why the beliefs were necessary for you, and what feelings were associated with the beliefs? Instead of the … Continue reading Manufacturing PTSD evidence with machine learning

Welcome – How Primal Therapy relates to recent scientific research

What does Primal Therapy have to do with science? To illustrate how applying principles of Dr. Arthur Janov’s Primal Therapy can provide additional information that’s relevant to recent scientific research, let’s start with the How do we assess “importance” in our lives? An example from scientists’ research choices study. Do you agree that a person’s … Continue reading Welcome – How Primal Therapy relates to recent scientific research

Prenatal stress produces offspring who as adults have cognitive, emotional, and memory deficiencies

This 2018 French/Italian/Swiss rodent study used the prenatally restraint stressed (PRS) model to create problems that could be resolved by various chemicals: “S 47445 is a positive modulator of glutamate AMPA-type receptors, possessing neurotrophic and enhancing synaptic plasticity effects as well as pro-cognitive and anti-stress properties. Most of studies examining the antidepressant effects of new … Continue reading Prenatal stress produces offspring who as adults have cognitive, emotional, and memory deficiencies
