Abstract

Research has elucidated causal links between stress exposure and the development of anxiety disorders, but due to the limited use of female or sex-comparative animal models, little is known about the mechanisms underlying sex differences in those disorders. This is despite an overwhelming wealth of evidence from the clinical literature that the prevalence of anxiety disorders is about twice as high in women compared to men, in addition to gender differences in severity and treatment efficacy. We here review human gender differences in generalized anxiety disorder, panic disorder, posttraumatic stress disorder and anxiety-relevant biological functions, discuss the limitations of classic conflict anxiety tests to measure naturally occurring sex differences in anxiety-like behaviors, describe sex-dependent manifestation of anxiety states after gestational, neonatal, or adolescent stressors, and present animal models of chronic anxiety states induced by acute or chronic stressors during adulthood. Potential mechanisms underlying sex differences in stress-related anxiety states include emerging evidence supporting the existence of two anatomically and functionally distinct serotonergic circuits that are related to the modulation of conflict anxiety and panic-like anxiety, respectively. We discuss how these serotonergic circuits may be controlled by reproductive steroid hormone-dependent modulation of crfr1 and crfr2 expression in the midbrain dorsal raphe nucleus and by estrous stage-dependent alterations of γ-aminobutyric acid (GABAergic) neurotransmission in the periaqueductal gray, ultimately leading to sex differences in emotional behavior.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The left central amygdala is activated by stimuli and negative emotions in women, while in men it is activated by positive emotions.

    “Specifically, the left central amygdala is activated by stimuli and negative emotions in women, 39 while in men, it is activated by positive emotions. 64”

    From Factors associated with gender and sex differences in anxiety prevalence and comorbidity: A systematic review (2022) · cites this paper as [64]

    The section on anxiety-relevant physiological and psychological gender differences reports stronger left central amygdala activation with negative emotions in women and with positive emotions in men, each relative to the other sex. The citing sentence omits that comparative qualifier, and the passage does not separately establish activation by unspecified stimuli in women. (LLM, conf=0.85)

  • Gender socialization is, at least in part, responsible for the development of psychosocial characteristics that act as risk factors for women and protective factors for men in the onset and course of anxiety.

    “The results seem to indicate that gender socialization is, at least in part, responsible for the development of the psychosocial characteristics that act as risk factors for women and protective factors for men in the onset and course of anxiety.44,54,56,59,64,70”

    From Factors associated with gender and sex differences in anxiety prevalence and comorbidity: A systematic review (2022) · cites this paper as [64]

    The sections on the significance of gender differences and on human gender differences report higher anxiety prevalence in women and increased rumination in girls. The PTSD section also considers societal victimization as a possible contributor. The paper does not establish that gender socialization develops psychosocial risk factors for women or protective factors for men. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Of the 44 documents, 31 were empirical/quantitative studies and 13 were reviews.

    “Of the 44 documents, 31 were empirical/quantitative studies30–60 and 13 were reviews.61–73”
  • Brain regions relevant to emotions (fear) and their regulation, such as the hippocampus, amygdala, and prefrontal cortex, are one possible explanation for differences in anxiety between sexes.

    “With respect to the latter, it has been pointed out that one of the possible explanations for differences in anxiety between the sexes resides in the brain regions relevant to emotions (i.e. fear) and their regulation, such as the hippocampus, amygdala, and prefrontal cortex.63,64”
  • Sex differences in anxiety disorders may be due to fluctuations of sexual hormones that affect the anxious state of women.

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.
