Memory and cognitive signs were connected to self-reported sleep apnea, cross-sectional information from the National Health and Nutrition Examination Survey (NHANES) revealed.
In a study of more than 4,200 U.S. grownups, those who reported sleep apnea signs had higher chances of likewise reporting memory or cognitive signs (OR 1.88, 95% CI 1.48-2.37, P< 0.001), stated Dominique Low, MD, MPH, of Boston Medical Center, in an abstract launched in advance of the American Academy of Neurology yearly conference.
“Sleep apnea is a typical condition that is typically underdiagnosed, yet treatments are offered,” Low stated in a press release.
“These findings highlight the significance of early screening for sleep apnea,” she included. “Effective treatments like constant favorable air passage pressure [CPAP] makers are easily offered.”
Relationships in between sleep and cognition are well-studied and seem intricate. In 2023, a pooled analysis of sleep research studies in almost 6,000 grownups revealed that much better sleep combination and the lack of sleep apnea were connected with much better international cognition over 5 years.
In another 2023 research study, sleep-disordered breathing was connected to median temporal lobe volumes in amyloid-positive older grownups who were cognitively unimpaired.
Prior research study likewise has actually revealed a bidirectional relationship in between dementia and sleep that might cover years.
In her analysis, Low evaluated information from 4,257 individuals over age 20 in the CDC’s 2017-18 NHANES mate. Individuals finished surveys that evaluated sleep, memory, cognition, and decision-making capabilities.
Individuals who reported snorting, gasping, or breathing stops briefly throughout sleep were categorized as having sleep apnea signs. Those who reported trouble keeping in mind, durations of confusion, trouble focusing, or decision-making issues were categorized as having memory or cognitive signs.
The relationship in between sleep apnea signs and memory or cognitive signs stayed considerable after changing for age, sex, race, and education (OR 2.2, 95% CI 1.58-2.59, P< 0.001), Low stated.
“These findings support the value of early screening and intervention for sleep apnea and recommend a relationship in between sleep apnea and cognitive function, a location of increasing public health significance,” she composed.
“Given the common underdiagnosis and undertreatment of sleep apnea, proactive procedures in screening and handling sleep apnea are required,” she included.
The research study had a number of restrictions, she acknowledged. The findings originated from one cross-sectional picture and did not follow individuals with time. All signs were self-reported and were not examined by doctor. While the study information revealed favorable associations, it might not identify whether sleep apnea triggers cognitive decrease.
“Further work ought to study the relationship in between sleep apnea and cognitive disability,” Low kept in mind.
