What was done
This narrative review synthesized current preclinical and clinical literature examining how maternal sleep deprivation (MSD) during pregnancy affects placental function, fetal neurodevelopment, and potential long-term programming of brain aging trajectories in offspring within the Developmental Origins of Health and Disease framework.
What was found
The abstract reports no quantitative values or statistical results. It qualitatively outlines mechanisms associated with prenatal sleep disruption (such as altered hypothalamic-pituitary-adrenal axis activity, systemic inflammation, oxidative stress, and circadian disruption) and links them to downstream fetal alterations, including epigenetic modifications, mitochondrial dysfunction, microglial activation, and disrupted neurogenesis that may impair cognitive and emotional outcomes and influence pathways associated with brain aging.
Why it matters
The review organizes mechanistic pathways connecting gestational sleep disturbances to offspring neurodevelopmental vulnerability and potential accelerated brain aging.
Limits
As a narrative review, it presents no original empirical data, quantitative effect estimates, or systematic search methodology. Direct evidence connecting maternal sleep deprivation to pathological brain aging in humans remains unestablished, and key modifiers such as gestational timing, duration of exposure, sex-specific responses, and postnatal environmental factors are not fully resolved.
