Sleep medications for older patients who report sleep problems may not be the best treatment given growing evidence of the link between these medications and the risk of incident dementia.
Adults aged 65 years and older who used sleep medications 5-7 days a week demonstrated a 30% increased risk of dementia, compared with those who did not use sleep medications, findings from a prospective study of 6,373 individuals show.
Adults aged 65 and older report a higher burden of sleep problems than other age groups, but major medical associations discourage the use of sleep medications by older adults because of growing evidence of a link between sleep medication use and cognitive decline, wrote Rebecca Robbins, MD, of Brigham and Women’s Hospital, Boston, and colleagues. However, data on this association among adults in the United States are limited, they said.
In a study published in Sleep Medicine, the researchers surveyed 6,373 adults aged 65 years and older who were enrolled in the nationally representative National Health and Aging Trends Study (NHATS). The majority of the participants were non-Hispanic White (71%), 59% were women, and 21% ranged in age from 70 to 74 years.
Participants responded to questions about routine sleep medication use. Routine was defined as “most nights” or “every night.” The data were collected for an 8-year period from 2011 to 2018. The study began in 2011, with a core interview administered annually.
Approximately 15% of the study population reported routine use of sleep medications. Overall, routine use of sleep medication was significantly associated with risk of incident dementia (hazard ratio, 1.30; P < .01) after controlling for multiple variables including age, sex, education level, and chronic conditions.
Dementia screening was conducted by participants rating their memory and then performing a memory-related activity (immediate and delayed 10-word recall) and other exercises to assess executive function and orientation. A separate eight-item informant screener was performed for patient proxies. The researcher noted, “Sensitivity of the NHATS probable dementia screening measure has been determined in previous research to be 66%, and specificity is 87%, with respect to a clinical dementia diagnosis.”
The study findings were limited by several factors including the use of self-reports, the lack of data on type or dose of sleep medication, and lack of data on the indication for the prescription, the researchers noted.
“Also, sleep medication use leads to worse performance on cognitive testing, such as the questionnaires used to screen for dementia in this study, and therefore could have resulted in a false diagnosis of dementia,” they added.
However, the results were strengthened by the large, nationally representative study population and support the need for quality geriatric care, the researchers said.
“Our findings provide further support and evidence that sleep medications are all too commonly administered, yet associated with greater risk for incident dementia, and that the U.S. health care system is in need of creative solutions for addressing poor sleep among older individuals,” they concluded.
Implications and alternatives
The study is important as the number of aging Americans increases, said Carolyn M. D’Ambrosio, MD, FCCP, of Brigham and Women’s Hospital and Harvard Medical School, Boston, in an interview. “In the elderly, inability to fall asleep or stay asleep are common issues that are brought to a health care provider,” she said. Dr. D’Ambrosio said she was not surprised by the study findings “as elderly patients often have sleep issues and sometimes a well-meaning health care provider gives them sleep medication to help. We have known that some of these sleep medications such as benzodiazepines affect cognitive performance,” she said.
Dr. D’Ambrosio said she avoids prescribing sleep medications for older adults if possible. “A deep dive into sleep habits, environment, and other things that disrupt sleep often gets to the problem rather than just masking it with a sleep medication,” she noted. Alternatives to improve sleep in older adults include exercise, exposure to bright light during the day, and good healthy sleep habits, all of which contribute to improved sleep in the elderly, said Dr. D’Ambrosio. She also recommends screening older adults for other issues that affect sleep, such as chronic pain.
The current study highlighted the association between sleep medication use and dementia, but it does not show causation, Dr. D’Ambrosio said. “So much more needs to be done to determine whether the sleep medications are causing worsening cognitive function long term, or if the dementia is starting but not yet diagnosed and the sleep medication is given but not the cause of the dementia, she noted.
Research gaps and treatment strategies
Older adults experiencing sleep difficulties may try various medications including pharmacologics (e.g., benzodiazepines), over-the-counter agents, such as diphenhydramine or doxylamine preparations, and/or herbal and nutritional supplements such as valerian or melatonin, said Mary Jo S. Farmer, MD, FCCP, of the University of Massachusetts Medical School–Baystate, Springfield, in an interview. “However, sleep medications, particularly benzodiazepines, are strongly discouraged by major medical associations including the American Geriatrics Society in part because of the growing evidence that use of sleep medications is associated with cognitive impairment and decline,” she said.
The current study results contribute to previous work demonstrating that both pharmacologic and nonpharmacologic sleep medication, although commonly administered, is associated with subsequent adverse outcomes in older adults, Dr. Farmer said. This association sets the stage for creative and different solutions for addressing poor sleep among older adults, such as behavioral treatments including cognitive-behavioral therapy, she noted.
Dr. Farmer said, “Areas for future research include exploring the causal link between prescription and/or over-the-counter sleep medication use and incident dementia in a randomized controlled trial,” she added.
“Another interesting opportunity for future research is to explore the indications for sleep medications among older adults since it has been shown in the general population that sleep difficulties represent only 12% of the indication for sleep medication prescriptions,” Dr. Farmer noted. “Future research could examine the strength of the underlying motivation to use sleep medication even in light of suggested long-term effects, and the effectiveness of other measures to avoid or minimize sleep difficulties,” she said.
“My experience is that the majority of ambulatory patients recently seen in sleep clinic want to avoid long-term use of sleep medications and will ask what other measures can be tried to consistently achieve a good night’s sleep without medication use,” Dr. Farmer said. “If medications are used, patients would rather try melatonin than a benzodiazepine. Many patients who come to sleep clinic with sleep medications already prescribed and are subsequently found to have sleep apnea and/or restless legs find that they no longer need sleep medication when these other medical conditions are appropriately diagnosed and managed,” she explained. “Finally, many patients tell me they feel less energetic upon awakening, almost feel hung over, and express being less sharp cognitively when taking pharmacologic sleep medication, whether for short or long periods of time, and therefore they want to avoid continuing with sleep medication use,” she said.
Dr. Farmer’s strategy for developing alternatives to sleep medications in older adults includes taking a careful history, including a complete list of medical problems, review of medications, and a thorough sleep history including usual time of sleep onset, awake time, and the frequency of daytime naps. “Tips for improving the quality of nighttime sleep may include adequately treating pain and other medical conditions such as heartburn, sleep apnea, and restless legs, creating a soothing environment to promote sleep by eliminating noise and bright lights, avoiding stimulant medications and substances such as caffeine and nicotine before bedtime, avoiding excessive amounts of alcohol, avoiding diuretics before bedtime, encouraging physical activity during the day, spending time in the sunlight as much as possible to help regulate the sleep cycle, limiting daytime naps, and establishing a regular sleep schedule,” she said.
The study was supported by National Institutes of Health awards K01HL150339, U54MD000538, K07AG052685, R01AG056531, R01AG056031. Lead author Dr. Robbins had no financial conflicts to disclose. Dr. D’Ambrosio disclosed serving as a section editor for sleep medicine for Dynamed and owning a patent on a circadian programming device. Dr. Farmer had no disclosures.
