Use of Body Sensors to Examine Nocturnal Agitation, Sleep, and Urinary Incontinence in Individuals With Alzheimer's Disease

Review of Risk Factors Associated With Biomarkers for Alzheimer Disease

ABSTRACT

BACKGROUND: Alzheimer disease (AD) is a neurodegenerative disease with no cure. The number of individuals living with AD doubles every 5 years. The current clinical practice relies on clinical history, mental status tests, cerebrum imaging, and physical and neurological examinations; however, recent advances in the field of biomarkers have provided clues for the early detection of AD. High levels of tau and low levels of amyloid-β (Aβ) in cerebrospinal fluid are well-known biomarkers for AD. METHODS: A database search of PubMed, Ovid MEDLINE, and CINAHL was conducted to identify relevant articles published within the last 5 years. The search was limited to articles concerning adults 65 years or older and published in the English language. Twelve articles were included in the review. RESULTS: Risk factors of sleep disruption, depression, and motor function are implicated. Cerebrospinal fluid parameters for biomarkers of tau and Aβ were universally lower among Blacks compared with Whites, raising concern that norm reference may not be accurate for all populations. Older adults are more at risk for AD. Results are inconclusive regarding whether depression is related to Aβ and tau pathology. CONCLUSION: Nurses should screen for sleep architecture, depression, and motor function in their patients and educate them on good sleep hygiene. Sleep studies should be advocated for people with suspected sleep apnea to mitigate the risk factor related to abnormal Aβ and tau pathology. Falls and decreased motor function require screening because they may be early indicators of abnormal biomarkers leading to AD.

Technological Solutions for Urinary Continence Care Delivery for Older Adults: A Scoping Review

PURPOSE

The aim of this scoping review was to examine available evidence regarding use of technology-based continence care delivery for older adults and to identify gaps in knowledge.

METHODS

Scoping review.

SEARCH STRATEGY

With the help of a medical librarian, CINAHL, Cochrane Library, EMBASE, MEDLINE, ProQuest, PubMed, SCOPUS, Web of Science, and websites were searched. Search terms included technology, sensors, older adults, urinary incontinence, continence care, nursing homes, long-term care, and continence management. All literature elements except for opinion pieces and case reports written in English within the last 15 years were included. Articles not written in the English language were excluded; our search indicated that less than 6% of returned elements were written in other languages.

FINDINGS

After duplications were removed, 2146 potential sources were identified. After exclusions, 19 results were included in the review. Review findings suggest positive effects of technology-based continence care on older adults and those involved in their care such as enhanced delivery of a successful toileting program. Information on potential harms, from either the perspective of care provider or recipient, is limited. It is important that needs of older adults and collaborative efforts are considered in the implementation of technology-based continence care. A paucity of guidelines on the use and adoption of technology-based continence care was found; additional research into uptake and sustainability is needed.

CLINICAL IMPLICATIONS

Technological solutions, such as sensors, need to be accurate in the measurement of urine saturation levels and timely in notifying caregivers for effective delivery of continence care. Adverse consequences of incontinence, such as incontinence-associated dermatitis or urinary tract infection, may potentially be reduced or avoided with technology-based continence care delivery.

Wrist accelerometry for monitoring dementia agitation behaviour in clinical settings: A scoping review

Agitated behaviour among elderly people with dementia is a challenge in clinical management. Wrist accelerometry could be a versatile tool for making objective, quantitative, and long-term assessments. The objective of this review was to summarise the clinical application of wrist accelerometry to agitation assessments and ways of analysing the data. Two authors independently searched the electronic databases CINAHL, PubMed, PsycInfo, EMBASE, and Web of Science. Nine (n = 9) articles were eligible for a review. Our review found a significant association between the activity levels (frequency and entropy) measured by accelerometers and the benchmark instrument of agitated behaviour. However, the performance of wrist accelerometry in identifying the occurrence of agitation episodes was unsatisfactory. Elderly people with dementia have also been monitored in existing studies by investigating the at-risk time for their agitation episodes (daytime and evening). Consideration may be given in future studies on wrist accelerometry to unifying the parameters of interest and the cut-off and measurement periods, and to using a sampling window to standardise the protocol for assessing agitated behaviour through wrist accelerometry.
