Symptoms of sleep apnea, including snorting, gasping, or paused breathing during sleep, are associated with a significantly greater risk for problems with cognition and memory, results from a large study showed.
Data from a representative sample of US adults show that those who reported sleep apnea symptoms were about 50% more likely to also report cognitive issues vs their counterparts without such symptoms.
“For clinicians, these findings suggest a potential benefit of considering sleep apnea as a possible contributing or exacerbating factor in individuals experiencing memory or cognitive problems. This could prompt further evaluation for sleep apnea, particularly in at-risk individuals,” study investigator Dominique Low, MD, MPH, department of neurology, Boston Medical Center, told this news organization.
The findings will be presented at the American Academy of Neurology (AAN) 2024 Annual Meeting on April 17.
Need to Raise Awareness
The findings are based on 4257 adults who participated in the 2017-2018 National Health and Nutrition Examination Survey and completed questionnaires covering sleep, memory, cognition, and decision-making abilities.
Those who reported snorting, gasping, or breathing pauses during sleep were categorized as experiencing sleep apnea symptoms. Those who reported memory trouble, periods of confusion, difficulty concentrating, or decision-making problems were classified as having memory or cognitive symptoms.
Overall, 1079 participants reported symptoms of sleep apnea. Compared with people without sleep apnea, those with symptoms were more likely to have cognitive problems (33% vs 20%) and have greater odds of having memory or cognitive symptoms, even after adjusting for age, gender, race, and education (adjusted odds ratio, 2.02; P < .001).
“While the study did not establish a cause-and-effect relationship, the findings suggest the importance of raising awareness about the potential link between sleep and cognitive function. Early identification and treatment may improve overall health and potentially lead to a better quality of life,” Dr. Low said.
Limitations of the study include self-reported data on sleep apnea symptoms and cognitive issues sourced from one survey.
Consistent Data
Reached for comment, Matthew Pase, PhD, with the Turner Institute for Brain and Mental Health, Monash University, Melbourne, Australia, said the results are similar to earlier work that found a link between obstructive sleep apnea (OSA) and cognition.
For example, in a recent study, the presence of mild to severe OSA, identified using overnight polysomnography in five community-based cohorts with more than 5900 adults, was associated with poorer cognitive test performance, Dr. Pase told this news organization.
“These and other results underscore the importance of healthy sleep for optimal brain health. Future research is needed to test if treating OSA and other sleep disorders can reduce the risk of cognitive impairment,” Dr. Pase said.
Yet, in their latest statement on the topic, reported by this news organization, the US Preventive Services Task Force concluded there remains insufficient evidence to weigh the balance of benefits and harms of screening for OSA among asymptomatic adults and those with unrecognized symptoms.
The study had no specific funding. Dr. Low and Dr. Pase had no relevant disclosures.
