Abstract

Post-traumatic stress disorder (PTSD) is a prevalent, debilitating and sometimes deadly consequence of exposure to severe psychological trauma. Although effective treatments exist for some individuals, they are limited. New approaches to intervention, treatment and prevention are therefore much needed. In the past few years, the field has rapidly developed a greater understanding of the dysfunctional brain circuits underlying PTSD, a shift in understanding that has been made possible by technological revolutions that have allowed the observation and perturbation of the macrocircuits and microcircuits thought to underlie PTSD-related symptoms. These advances have allowed us to gain a more translational knowledge of PTSD, have provided further insights into the mechanisms of risk and resilience and offer promising avenues for therapeutic discovery.

  • Much of our understanding draws from studies on the dissociative subtype of PTSD.

    “Much of our understanding draws from studies on the dissociative subtype of PTSD [105,143].”

    From Treatment of dissociative identity disorder: leveraging neurobiology to optimize success (2024) · cites this paper as [143]

    The Avoidance section discusses the dissociative subtype, and the References list several studies of its brain circuitry. The paper does not say that much of our understanding of PTSD draws from those studies; it also describes advances from broader human neuroimaging and animal-circuit research. No page number is available in our copy. (LLM, conf=0.78)

  • Induced ELS via the maternal separation model reduces pre- and post-synaptic protein expression of inhibitory neurons in the mPFC.

    “Additionally, induced ELS via the maternal separation model reduces pre- and post-synaptic protein expression of inhibitory neurons in the mPFC (124).”

    From Childhood Trauma, the HPA Axis and Psychiatric Illnesses: A Targeted Literature Synthesis (2022) · cites this paper as [124]

    The Intrusion symptoms section discusses prefrontal inhibitory interneurons and fear behaviour, while the Dissociative amnesia and memory deficits section describes stress-related protein changes in the hippocampus. Neither addresses reduced pre- and post-synaptic protein expression in mPFC inhibitory neurons after maternal separation. Searches for maternal separation and inhibitory synaptic proteins found no passage supporting the claim; page numbers were not available in our copy. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
