The Claim
Among older women with cognitive risk factors, 67% have undiagnosed obstructive sleep apnea.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In older women who show signs of cognitive decline, two out of three have obstructive sleep apnea that has not been diagnosed.
See the scientific wording
In a cohort of older women with cognitive risk factors, 67% had undiagnosed obstructive sleep apnea, highlighting a substantial gap in detection among a population at elevated risk for Alzheimer’s disease.
In older women with cognitive risk factors, repeated breathing interruptions during sleep cause oxygen levels to drop and sleep to fragment. These disruptions trigger inflammation throughout the body, which spreads to the brain and accelerates the buildup of abnormal tau protein. This process damages brain regions involved in memory and thinking, but the sleep problem remains unnoticed because symptoms are subtle or attributed to aging.
What the research says
1 studyStudy: APOE4 modifies the association between sleep apnea, inflammation, and tau pathology in older women
In a group of older women already at higher risk for Alzheimer’s, the study found that 67% had sleep apnea they didn’t know about — exactly what the claim says. So yes, many at-risk women are missing this diagnosis.
