Sleep and Cognition in Community-Dwelling Older Adults: A Review of Literature
Changes in sleep and cognition occur with advancing age. While both may occur independently of each other, it is possible that alterations in sleep parameters may increase the risk of age-related cognitive changes. This review aimed to understand the relationship between sleep parameters (sleep latency, wake after sleep onset, sleep efficiency, sleep duration, general sleep complaints) and cognition in community-dwelling adults aged 60 years and older without sleep disorders. Systematic, computer-aided searches were conducted using multiple sleep and cognition-related search terms in PubMed, PsycINFO, and CINAHL. Twenty-nine manuscripts met the inclusion criteria. Results suggest an inconsistent relationship between sleep parameters and cognition in older adults and modifiers such as depressive symptoms, undiagnosed sleep apnea and other medical conditions may influence their association. Measures of sleep and cognition were heterogeneous. Future studies should aim to further clarify the association between sleep parameters and cognitive domains by simultaneously using both objective and subjective measures of sleep parameters. Identifying which sleep parameters to target may lead to the development of novel targets for interventions and reduce the risk of cognitive changes with aging
Insomnia in the older adult
KEY POINTS
- The incidence of insomnia increases with aging. Insomnia can include difficulty falling asleep at the start of the sleep period, waking up during the night and having difficulty falling back asleep, and waking up early and being unable to get back to sleep. Difficulty staying asleep and early morning insomnia are common in older adults with insomnia disorder.
- When diagnosing insomnia, health care providers need to collect a thorough health history and include questions about the older adult’s sleep, medical, and psychiatric history.
- Cognitive-behavioral therapy for insomnia, which consists of stimulus control, sleep restriction, sleep hygiene, and cognitive therapy, is the recommended first-line therapy for treatment of insomnia in older adults.
- Because of the higher risk for adverse effects in older patients, medications should be used sparingly and, when possible, be discontinued.
- Cognitive-behavioral therapy for insomnia has been shown to be more efficacious than medications for the long-term management of insomnia in older adults
Insomnia in the older adult
Although insomnia is not a normal part of the aging process, its prevalence increases with age. Factors such as medications and medical and psychiatric disorders can increase the risk for insomnia. In order to diagnose insomnia, it is important for older adults to complete comprehensive sleep and health histories. Cognitive behavioral therapy for insomnia, which includes stimulus control, sleep restriction, sleep hygiene, and cognitive therapy, is the recommended first-line treatment of insomnia and is more effective that medications for the long-term management of insomnia. Medications such as benzodiazepines and antidepressants should be avoided for the treatment of insomnia in older adults
Association of health related quality of life domains with daytime sleepiness among elderly recipients of long-term services and supports
Excessive daytime sleepiness (EDS) is prevalent in older adults; however, data are lacking that examine EDS across living environments. The aims of this secondary data analysis were to identify the prevalence and predictors of EDS among older adults receiving long-term services and supports (LTSS) in assisted living communities (ALCs), nursing homes (NHs), and the community. Participants (n = 470) completed multiple measures including daytime sleepiness. Logistic regression modeling was used to identify EDS predictors. Participants were primarily female and white with a mean age of 81 ± 9 years. The overall prevalence of EDS was 19.4%; the prevalence differed across living environment. Older adults in ALCs and NHs had higher odds of EDS than those living in the community. Also, depressive symptoms and number of bothersome symptoms predicted EDS. Upon admission for LTSS, evaluating older adults, especially those in ALCs and NHs, for depression and bothersome symptoms may reveal modifiable factors of EDS

Determinants of behavioral and psychological symptoms of dementia: A scoping review of the evidence
BackgroundBehavioral and psychological symptoms of dementia (BPSD) are prevalent in people with neurodegenerative diseases.PurposeIn this scoping review the Kales, Gitlin and Lykestos framework is used to answer the question: What high quality evidence exists for the patient, caregiver and environmental determinants of five specific BPSD: aggression, agitation, apathy, depression and psychosis?MethodAn a priori review protocol was developed; 692 of 6013 articles retrieved in the search were deemed eligible for review. Gough's Weight of Evidence Framework and the Cochrane Collaboration's tool for assessing risk of bias were used. The findings from 56 high quality/low bias articles are summarized.DiscussionEach symptom had its own set of determinants, but many were common across several symptoms: neurodegeneration, type of dementia, severity of cognitive impairments, and declining functional abilities, and to a lesser extent, caregiver burden and communication.ConclusionResearch and policy implications are relevant to the National Plan to Address Alzheimer's Disease
