Abstract

Gender inequality substantially impacts society, disproportionately disadvantaging women, especially in the Global South. This inequality correlates with brain health outcomes for women, including a higher risk of cognitive decline and dementia. This perspective highlights how sex-linked biology and gender disparities affect women's brain health in the Global South through various pathways, such as differential exposome, health behaviors, and gender biases in research and healthcare systems. Alzheimer's disease and other brain health conditions exemplify how sex-specific risk factors and gender-related health barriers interact to influence brain health. We advocate for incorporating sex/gender considerations in research, policy, and clinical practice to improve brain health interventions in the Global South. Additionally, we propose using the patient and public involvement framework to effectively tailor health strategies that address these factors.

  • Resilience is understudied in the majority world, including low-, middle-, and upper-middle-income countries, where socioeconomic inequities, environmental stressors, high disease burdens, and limited healthcare access create distinct health trajectories.

    “While extensively studied in high-income countries, resilience remains underexplored in the majority world, including low-, middleand upper-middle-income countries—where socioeconomic inequities, environmental stressors, large burdens of infectious and noncommunicable diseases and limited healthcare access shape unique health trajectories6–15.”

  • Transgender and gender-diverse individuals face distinct brain health challenges, especially in low-resource settings, due to stigma, discrimination, and limited access to care, which can increase allostatic load.

    “Transgender and gender-diverse individuals face distinct brain health challenges, especially in low-resource settings due to stigma, discrimination and limited access to care, which can increase allostatic load7.”

    From Resilience and brain health in global populations (2025) · cites this paper as [7]

    The “Gender-biased health systems” section says transgender women in the Caribbean face healthcare discrimination that may limit access to brain health services, and that violence against sexual and gender minorities in Southern Africa contributes to chronic stress and poor mental health. The “Making the case for sex and gender” section links inequality to increased allostatic load specifically for women; it does not make that link specifically for transgender and gender-diverse people. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Sex, gender, ethnicity, and age influence resilience through their effects on stress responses.

    “Sex, gender, ethnicity, and age all shape resilience via their influence on responses to stress7,99–106.”

    From Resilience and brain health in global populations (2025) · cites this paper as [7]

    In “Making the case for sex and gender” (page unavailable), the paper says gender inequalities could increase women’s allostatic load from chronic stress, with worse brain-health outcomes. It also discusses women’s cognitive resilience in early Alzheimer’s disease (“Sex related differences in risk factors and brain health conditions,” page unavailable). It does not establish that sex, gender, ethnicity, and age all shape resilience through their effects on stress responses. (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.
