Impact of maternal sleep apnea on fetal brain development
Official title: Mechanisms of Hypoxia-Mediated Disturbances in Cerebral Maturation in a Fetal Ovine Model of Maternal Sleep Apnea
Funded at Oregon Health & Science University · NIH-11004356 · Data updated 2026-11-12
This study is looking at how low oxygen levels from sleep apnea in pregnant women might impact the development of their baby's brain, especially areas important for learning and memory, to help understand any potential risks for the baby's growth and brain function.

Who could benefit from this research
✓Could help
Ideal candidates for this research are pregnant women experiencing sleep apnea, particularly in the third trimester.
✕Less likely to help
Patients who are not pregnant or those without sleep apnea may not benefit from this research.
What this research studies
This research investigates how episodes of low oxygen levels caused by maternal sleep apnea affect the development of the fetal brain, particularly focusing on the hippocampus, which is crucial for learning and memory. Using a novel model, the study will monitor fetal brain oxygen levels and assess how these conditions lead to cell death and inflammation in the brain. The researchers will also explore how these disruptions affect the maturation of important neural connections and the overall function of the brain during development.
Why it matters
Potential benefit: If successful, this research could lead to better understanding and interventions for cognitive and developmental issues in children born to mothers with sleep apnea.
How similar studies have gone: While the specific model used in this research is novel, previous studies have indicated that maternal health conditions can significantly impact fetal brain development.
