Effect of a high-intensity exercise program on physical function and mental health in nursing home residents with dementia: an assessor blinded randomized controlled trial

Ten-year trends in non-surgical patients requiring intensive care: Long-term prognostic differences by year of admission

BACKGROUND

The aim of the present study is to elucidate prognostic impact of temporal trends of non-surgical patients requiring intensive care over a 10-year period.

METHODS AND RESULTS

A total of 4276 non-surgical patients requiring intensive care from 2012 to 2021 were enrolled. Patients' backgrounds, in-hospital management, and prognoses were compared between five groups [2012-2013 (n = 825), 2014-2015 (n = 784), 2016-2017 (n = 864), 2018-2019 (n = 939), and 2020-2021 (n = 867)]. During the study period, mean age significantly increased from 69 years in 2012-2013 to 72 years in 2020-2021. Mean Acute Physiology and Chronic Health Evaluation scores significantly increased from 10 points in 2012-2013 to 12 points in 2020-2021. The median duration of intensive care unit stays increased from 3 to 4 days. Kaplan-Meier survival curve analysis showed that survival rates during 30- and 365-days were significantly lower in 2020-2021 than in 2012-2013, but it was not significantly different by a Cox proportional hazards regression model in 30 days. A Cox proportional hazards regression model revealed that the risks of 365-day all-cause death were significantly higher in patients enrolled in 2016-2017 (HR: 1.324, 95 % CI: 1.042-1.680, p = 0.021), in 2018-2019 (HR: 1.329, 95 % CI: 1.044-1.691, p = 0.021), and in 2020-2021 (HR: 1.409, 95 % CI: 1.115-1.779, p = 0.004).

CONCLUSION

The condition of patients requiring intensive care is becoming more critical year by year, leading to poorer long-term prognoses despite improvements in treatment strategies. These findings emphasize the importance of additional care management after admission into non-surgical intensive care units, particularly for the aging society of Japan.

Effective dosage and mode of exercise for enhancing cognitive function in Alzheimer's disease and dementia: a systematic review and Bayesian Model-Based Network Meta-analysis of RCTs

OBJECTIVE

Research the dose-response relationship between overall and certain types of exercise and cognitive function in older adults with Alzheimer's disease and dementia.

DESIGN

Systemic and Bayesian Model-Based Network Meta-Analysis.

METHODS

In our study, we analyzed data from randomized controlled trials investigating the effects of different exercises on cognitive outcomes in older adults with AD. We searched the Web of Science, PubMed, Cochrane Central Register of Controlled Trials, and Embase up to November 2023. Using the Cochrane Risk of Bias tool (Rob2) for quality assessment and R software with the MBNMA package for data analysis, we determined standard mean differences (SMDs) and 95% confidence intervals (95%CrI) to evaluate exercise's impact on cognitive function in AD.

RESULTS

Twenty-seven studies with 2,242 AD patients revealed a nonlinear relationship between exercise and cognitive improvement in AD patients. We observed significant cognitive enhancements at an effective exercise dose of up to 1000 METs-min/week (SMDs: 0.535, SD: 0.269, 95% CrI: 0.023 to 1.092). The optimal dose was found to be 650 METs-min/week (SMDs: 0.691, SD: 0.169, 95% CrI: 0.373 to 1.039), with AE (Aerobic exercise) being particularly effective. For AE, the optimal cognitive enhancement dose was determined to be 660 METs-min/week (SMDs: 0.909, SD: 0.219, 95% CrI: 0.495 to 1.362).

CONCLUSION

Nonlinear dose-response relationship between exercise and cognitive improvement in Alzheimer's disease, with the optimal AE dose identified at 660 METs-min/week for enhancing cognitive function in AD.

The effectiveness of structured physical activity on agitation in people with dementia: a rapid review

OBJECTIVES

Managing agitation and other behaviours that challenge is a significant dementia care challenge. The priority is to find effective non-pharmacological interventions as drug treatments can have significant side effects. This review evaluates the effectiveness of structured physical activity on agitation in dementia.

METHOD

Our rapid review searched four electronic databases, Cochrane CENTRAL, MEDLINE, CINAHL and Embase, for interventional studies using a structured physical activity programme in people with dementia and studied the effect of this activity on behaviours that challenge. Study quality was assessed using CASP criteria and data was narratively synthesised.

RESULTS

We included 13 studies in this review (four rated as high quality), involving a total of 1546 participants. Results were analysed according to exercise type, frequency and intensity of the intervention. Exercise is effective in reducing agitation and studies with higher adherence to exercise demonstrated more positive effects on agitation and behaviours that challenge.

CONCLUSION

Physical activity can be effective in reducing agitation in older adults with dementia. Further research is needed to clarify the type of intervention that is most beneficial. Strategies to make physical activity more acceptable and available to people with dementia need to be established.

Insights into the management of Lewy body dementia: a scoping review

Lewy body dementia (LBD) is situated at the convergence of neurodegenerative disorders, posing an intricate and diverse clinical dilemma. The accumulation of abnormal protein in the brain, namely, the Lewy body causes disturbances in typical neural functioning, leading to a range of cognitive, motor, and mental symptoms that have a substantial influence on the overall well-being and quality of life of affected individuals. There is no definitive cure for the disease; however, several nonpharmacological and pharmacological modalities have been tried with questionable efficacies. The aim of this study is to figure out the role of different interventional strategies in the disease. Donepezil, rivastigmine, memantine, and galantamine were the commonly used drugs for LBD. Together with that, levodopa, antipsychotics, armodafinil, piracetam, and traditional medications like yokukansan were also used, when indicated. Talking about nonpharmacological measures, exercise, physical therapy, multicomponent therapy, occupational therapy, psychobehavioral modification, transcranial stimulation, and deep brain stimulation have been used with variable efficacies. Talking about recent advances in the treatment of LBD, various disease-modifying therapies like ambroxol, neflamapimod, irsenontrine, nilotinib, bosutinib, vodobatinib, clenbuterol, terazosin, elayta, fosgonimeton, and anle138b are emerging out. However, there drugs are still in the different phases of clinical trials and are not commonly used in clinical practice. With the different pharmacological and nonpharmacological modalities we have for treatment of LBD, all of them offer symptomatic relief only. Being a degenerative disease, definite cure of the disease can only be possible with regenerative measures.

Accountable Care Organization Attribution and Post-Acute Skilled Nursing Facility Outcomes for People Living With Dementia

OBJECTIVES

Under the Accountable Care Organization (ACO) model, reductions in healthcare spending have been achieved by targeting post-acute care, particularly in skilled nursing facilities (SNFs). People with Alzheimer disease and related dementias (ADRD) are frequently discharged to SNF for post-acute care and may be at particular risk for unintended consequences of SNF cost reduction efforts. We examined SNF length of stay (LOS) and outcomes among ACO-attributed and non-ACO-attributed ADRD patients.

DESIGN

Observational serial cross-sectional study.

SETTING AND PARTICIPANTS

Twenty percent national random sample of fee-for-service Medicare beneficiaries (2013-2017) to identify beneficiaries with a diagnosis of ADRD and with a hospitalization followed by SNF admission (n = 263,676).

METHODS

Our primary covariate of interest was ACO (n = 66,842) and non-ACO (n = 196,834) attribution. Hospital readmission and death were measured for 3 time periods (<30, 31-90, and 91-180 days) following hospital discharge. We used 2-stage least squares regression to predict LOS as a function of ACO attribution, and patient and facility characteristics.

RESULTS

ACO-attributed ADRD patients have shorter SNF LOS than their non-ACO counterparts (31.7 vs 32.8 days; P < .001). Hospital readmission rates for ACO vs non-ACO differed at ≤30 days (13.9% vs 14.6%; P < .001) but were similar at 31-90 days and 91-180 days. No significant difference was observed in mortality post-hospital discharge for ACO vs non-ACO at ≤30 days; however, slightly higher mortality was observed at 31-90 days (8.4% vs 8.8%; P = .002) and 91-180 days (7.6% vs 7.9%; P = .011). No significant association was found between LOS and readmission, with small effects on mortality favoring ACOs in fully adjusted models.

CONCLUSIONS AND IMPLICATIONS

Being an ACO-attributed patient is associated with shorter SNF LOS but is not associated with changes in readmission or mortality after controlling for other factors. Policies that shorten LOS may not have adverse effects on outcomes for people living with dementia.

Effect of a 36-Week Supervised Exercise Training Program on Physical and Cognitive Function in Older Patients With Dementia

BACKGROUND/AIM

To investigate the effects of an exercise training program on physical and cognitive function in older patients with dementia.

PATIENTS AND METHODS

Thirty-eight patients with early-middle dementia (31 females and seven males), aged 80.6±6.9 years, residents in an Elderly Care Unit, either completed a 36-week structured exercise program (Intervention Group, IG; n=19), or received the usual medical care (Control Group, CG; n=19). Before and after the 36-week intervention, cognitive function was evaluated in both groups by Mini-Mental State Examination (MMSE) and depression by Geriatric Depression Scale (GDS); physical function was assessed using handgrip test, Timed Up to Go (TUG), Berg Balance Scale (BBS) and Chair-Stand Test (CST), and daily living functionality by Functional Rating Scale for Symptoms of Dementia (FRSSD).

RESULTS

As a result of exercise intervention, participants scored better in all functional and cognitive test assessments compared to the control group, as reflected by absolute and relative (%) differences in all metrics after the 36-week exercise program (p<0.001).

CONCLUSION

A 36-week supervised exercise training program was found to result in significant improvements in physical and cognitive function of elderly patients in early to middle stages of dementia at an Elderly Care Unit. The promising results of this study shed more light on the adaptability of elderly patients with early and mild dementia to long-term exercise training and verified the feasibility of applying such programs in this clinical population.

Balance-based exercise programs on balance in older adults with mild to moderate dementia: A critically appraised topic

OBJECTIVE

It is well established that exercise programs including balanced-based exercises are practical and beneficial for cognitively healthy older adults. However, there is limited evidence to determine if these types of training regimens are effective for individuals with dementia. We conducted a critical appraisal to determine if the addition of balance-based exercise programs, compared with usual care at residential homes, improved balance in adults diagnosed with mild to moderate dementia.

MATERIALS AND METHODS

Four databases were searched for randomized control trials implementing balanced-based exercise programs with individuals diagnosed with mild to moderate dementia. The articles were evaluated based on the Centre for Evidence Based Medicine level of evidence criteria and appraised using the PEDro scale.

RESULTS

A comprehensive literature search revealed four studies relevant to the clinical question that fit the inclusion and exclusion criteria. All four studies indicated an improvement in balance following a weekly physical therapy program implementing balance-based exercises.

CONCLUSIONS

There is sufficient evidence to suggest that the use of physical therapy programs that include balance-based exercises, performed 1-2 times a week over the course of 12-25 weeks, improves balance in elderly adults with mild to moderate dementia.

The impact of technology on promoting physical activities and mental health: a gender-based study

BACKGROUND

Physical inactivity is a significant public health concern globally, associated with an increased risk of chronic diseases and detrimental effects on both physical and mental health. Technologically based interventions have emerged as a potential solution to promote physical activity engagement and improve mental health outcomes. However, understanding the effectiveness of these interventions and the role of gender in their outcomes is essential for developing tailored strategies.

OBJECTIVE

This study aims to examine the effectiveness of technologically based interventions in promoting physical activity and improving mental health outcomes, with a specific focus on gender differences.

METHODOLOGY

This study employed a three-phase mixed methods research design. Phase one was an experimental phase where 300 participants were randomly assigned to intervention or control groups. The intervention group received a technologically based physical activity intervention, while the control group did not. Physical activity levels and mental health outcomes were assessed before and after the intervention. Phase two involved qualitative interviews with a subset of participants (n = 20) from the intervention group. These interviews explored motivations and barriers to physical activity, aiming to uncover personal factors influencing engagement. Thematic analysis was used to identify recurring themes. Phase three utilized a quantitative survey to compare motivations and barriers between males and females. The survey, administered to a larger sample, included participants from both intervention and control groups. It assessed various factors and allowed for a quantitative comparison of gender differences.

FINDINGS

findings indicated that the intervention improved the mental health and physical activities level of the intervention groups. Findings also there are 8 motivations for and barriers to using technology in physical activities. Male and females' scores on some of the motivations and barriers were statistically significant.

CONCLUSION

technology plays an important role in improving the mental health and physical activities of adults. Findings can be used by health care centers, digital psychologists, and physical trainers.

Implementation of interventions to maintain and promote the functional mobility of nursing home residents - a scoping review

BACKGROUND

To provide an overview of the available evidence on the implementation of direct and capacity-building interventions to promote and maintain the functional mobility of nursing home residents.

METHODS

We conducted a scoping review following the methodological guidance for the conduct of scoping reviews as described by the Joanna Briggs Institute. We searched for studies in MEDLINE (via PubMed) and CINAHL (via EBSCO). We conducted a qualitative content analysis of the included studies with deductive categories based on the Consolidated Framework for Implementation Research (CFIR).

RESULTS

Ultimately, we included 8 studies on direct interventions, 6 studies on capacity-building interventions, and 2 studies on both types of interventions in our review. Seven studies provided evidence on implementation strategies comprising discrete as well as multifaceted, multilevel strategies. Most of the studies did not systematically evaluate the strategies but remained at a descriptive level. All 16 studies provided evidence of influencing factors. We identified 32 of the 37 influencing factors of the CFIR. The five most frequent influencing factors were available resources (n = 14), access to knowledge and information (n = 12), patient needs and resources (n = 10), knowledge and beliefs about the intervention (n = 10) and compatibility (n = 9).

CONCLUSIONS

The available evidence on the implementation of functional mobility interventions in nursing homes is rather limited. This emphasizes the need for further research. Regarding implementation strategies, the systematic evaluation and further development of the reported promising approaches might be a starting point.

Effects of High-Intensity Functional Training (HIFT) on the Functional Capacity, Frailty, and Physical Condition of Older Adults with Mild Cognitive Impairment: A Blind Randomized Controlled Clinical Trial

Physical exercise has been established as an intervention in the integral approach for the physical, functional, and social health of older adults. The objective of this study was to determine the effects of a high-intensity functional training (HIFT) program on the physical condition and functional capacity of an elderly Colombian population with mild cognitive impairment. This research corresponds to a blind randomized controlled clinical trial. A total of 169 men and women aged over 65 years were evaluated and distributed in two groups: the experimental group that received a 12-week HIFT intervention (n = 82) and the control group (n = 87) that received general recommendations on the benefits of physical exercise. The outcome variables included physical condition, assessed using the Senior Fitness battery (SNB); Fried's frailty phenotype was applied, and gait and balance were assessed using the Tinetti scale. For the functional variables, activities of daily living, instrumental activities of daily living, and advanced activities of daily living were evaluated. All variables were measured pre- and post-intervention. Statistically significant improvements were observed in the IG for gait stability and balance (p < 0.001), as well as for independence in activities of daily living (p = 0.003), and instrumental and advanced activities (p < 0.001). Likewise, greater functionality was found when assessed with the SNB (p < 0.001), except for upper limb strength. The frailty classification did not show changes post-intervention (p = 0.170) nor in the group x time interaction. MANCOVA analysis showed that regardless of gender, health level, age, BMI, cognition, and health level, the HIFT intervention produced better results in functional capacity, balance, and gait (F = 0.173, p < 0.001, Wilks' λ = 88.231).

Long-Term Effectiveness of Physical Exercise-Based Swallowing Interventions for Older Adults with Dementia in a Day-Care Center

Swallowing safety is one of the top health concerns of dementia. Coughing and choking (coughing/choking) are signs of impaired swallowing safety. This study aimed to investigate the effectiveness of regular physical exercise-based swallowing intervention for reducing coughing-choking at the dementia day-care center. This was a retrospective analysis with data from medical records, including age, the clinical dementia rating (CDR), and the frequencies of coughing/choking in ten days (10-day coughing/choking). Those who complied with the exercise programs were assigned to the exercise-based group (n = 22), and those who could not comply were assigned to the non-exercised-based group (n = 7). The non-exercised-based group showed more advanced age and higher CDR than the exercise-based group (p < 0.05). The 10-day coughing/choking showed significant decreases at the 5-month and 19-month in the exercise-based group and at the 5-month in the non-exercise-based group (p < 0.05). Our findings suggested that regular physical exercise-based swallowing intervention effectively alleviated coughing/choking problems of older adults with dementia and its effectiveness was long-lasting. For those who could not comply with exercise programs, noticeably with more advanced age and dementia, the effective swallowing intervention period was short-term.

Integrating social support into interventions among the elderly in nursing homes: a scoping review

OBJECTIVES

This study aimed to understand the evidence related to integration of social support into interventions, to identify literature gaps related to social support interventions, and to clarify dimensions of supportive functions, outcomes, and providers among the elderly in nursing homes.

DESIGN

This scoping review followed the approach by Arksey and O'Malley. The Mixed Methods Appraisal Tool V.2018 was used for quality assessment of the studies.

DATA SOURCES

Searches were conducted of the PubMed, ScienceDirect, Public Library of Science, SocioHub, Wiley Online Library and PsycINFO databases for publications from 2010 to 2021.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We searched for primary studies and heterogeneous study designs published in English. Eligible studies took place in nursing and care homes and had study populations of elderly adults (older adults, geriatrics, ageing, seniors, older people and those aged 60 years and older).

DATA EXTRACTION AND SYNTHESIS

A data extraction form based on Joanna Briggs Institute's recommendations for scoping reviews was used. Two reviewers independently extracted data and performed quality assessment of the studies. Then, extracted data and quality assessment reports were discussed by all authors.

RESULTS

Thirty-one eligible studies were included in this review. 54.8% of the studies provided interventions for cognitively impaired residents. The top-three outcomes were neuropsychiatric symptoms, physical function and quality of life, respectively. The interventions were performed by nursing home staff (83.9%), other persons with specific qualifications (58.1%) and health volunteers (6.5%). Most studies (90.3%) depicted the integration of emotional and instrumental supportive functions into interventions.

CONCLUSION

The appropriate dimensions of supportive function, mainly emotional and instrumental support, are important to integrate into the social care of elderly people living in nursing homes.

Effectiveness of non-pharmacological therapies on cognitive function in patients with dementia-A network meta-analysis of randomized controlled trials

Objective

Non-pharmacological therapies (NPTs) have received increasing attention from researchers as a category of treatment to improve cognitive impairment in patients with dementia because of their fewer side effects. In this study, photobiomodulation (PBM), enriched environment (EE), exercise therapy (ET), computerized cognitive training (CCT), and cognitive stimulation therapy (CST) were selected to compare the effects of NPTs that improve dementia by quantifying information from randomized controlled trials (RCTs).

Methods

We did a systematic review and network meta-analysis. We searched PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure Database, Wan Fang Database, Chinese Biomedical Literature Database, Web of Science, and VIP Database from the time of database creation to 1 August 2022. Two investigators independently screened the literature, extracted information, and assessed the RCTs' quality with the Cochrane Collaboration Network Risk of Bias 2.0. Network meta-analysis was performed using R language (X64 version 4.1.3) and STATA 17.0.

Results

We identified 1,268 citations and of these included 38 trials comprising 3,412 participants. For improving dementia, the results of the network meta-analysis showed that compared with the control group (CON), PBM (SMD = 0.90, 95% CI: 0.43-1.37), EE (SMD = 0.71, 95% CI: 0.02-1.41), ET (SMD = 0.42, 95% CI: 0.16-0.68), and CST (SMD = 0.36, 95% CI: 0.11-0.62) were significantly different (P < 0.05); There was no significant difference in CCT (SMD = 0.41, 95% CI: -0.07-0.88) (P > 0.05). The ranked results showed that PBM has more potential to be the best intervention (P = 0.90). In addition, there was a significant difference between PBM and CST in improving cognitive function (SMD = 0.54, 95% CI: 0.00; 1.08, P < 0.05).

Conclusion

In this study, NPTs have excellent potential to improve cognition in people with dementia, and PBM may have more significant benefits in improving cognition than the other four NPTs.

Effect of Adding Motorized Cycle Ergometer Over Exercise Training on Balance in Older Adults with Dementia: A Randomized Controlled Trial

BACKGROUND

Falls secondary to balance disturbances have been considered as a burden on health systems in people with dementia aged above 65. Exercise has been increasingly recommended to address such problem and the main challenges being the commitment and supervision of training. The study's aim was to investigate the effect of adding motorized cycle ergometer (MCE) on high intensity functional exercise (HIFE) training on balance and cognition in older adults with dementia.

METHODS

Sixty participants over the age of 65 were randomly allocated into 3 groups, Mo, Ex, and MoEx undergoing, respectively, 50 minutes MCE, HIFE, or combination of both. Sessions were done 3 times per week for 12 weeks. Outcome measures taken before and after study period were Berg Balance Scale (BBS), timed up and go test (TUG), and Mini Mental State Exam (MMSE).

RESULTS

All groups showed significant improvement in BBS scores but not on TUG or MMSE scores. Between group analysis showed no privilege of any used training methods over the other for all measures taken.

CONCLUSIONS

Training with HIFE, MCE, or combination of both is effective in improving balance but not cognition. However, MCE can be an alternative to supervised exercise training in addressing balance.

Relationship between Cognitive Function and Sway of Body in Standing Posture: A Cross-Sectional Study

BACKGROUND

The influence of neurological or balance dysfunction on cognitive impairment has not been well studied. We compared the results of the balance test, measured by either head or foot sway to consider whole body sway, with those of the cognitive impairment test.

METHODS

Individuals of either gender, aged over 60 years, underwent a 30 s balance test. We measured sway while standing on one-leg or two-legs. Sway was evaluated by the distance or area of movement of the head or foot pressure. We also evaluated the effect of visual condition: eyes-open (EO) or -closed (EC). The Mini-Mental State Examination (MMSE) was used to evaluate the degree of cognitive impairment.

RESULTS

The head sway area standing on one leg was significantly correlated to MMSE score with EO (correlation r = -0.462). In standing on two legs, no sway test results showed a significant correlation to MMSE scores with EO. With EC, the magnitude of sway became greater, and was significantly correlated to MMSE scores in the head distance.

CONCLUSION

Although the correlation between head sway and MMSE was not strong, head sway showed a stronger correlation than did foot pressure sway. Standing on one leg, as measured by head sway area, may thus predict cognitive impairment.

A Qualitative Study on the Experiences of Therapists Delivering the Promoting Activity, Independence and Stability in Early Dementia (PrAISED) Intervention During the COVID-19 Pandemic

BACKGROUND

The Promoting Activity, Independence and Stability in Early Dementia (PrAISED) intervention is a programme of physical activity and exercise designed to maintain participation in activities of daily living, mobility, and quality of life for people living with dementia. During the COVID-19 pandemic first national lockdown in England, the PrAISED physiotherapists, occupational therapists, and rehabilitation support workers adapted to delivering the intervention remotely via telephone or video conferencing.

OBJECTIVE

The aim of this study was to explore therapists' experience of delivering the PrAISED intervention during the COVID-19 pandemic and derive implications for clinical practice.

METHODS

Qualitative semi-structured interviews were conducted with 16 therapists using purposive sampling. Thematic analysis was used to analyze the transcripts.

RESULTS

Therapists reported a change in the relationship between themselves, the person with dementia and the caregiver, with an increased reliance on the caregiver and a loss of autonomy for the person living with dementia. There was concern that this would increase the burden on the caregiver. The therapists reported using creativity to adapt to different modes of delivery. They felt their sessions were mostly focused on providing social and emotional support, and that assessing, progressing, and tailoring the intervention was difficult.

CONCLUSION

It is possible to deliver some elements of a physical intervention using remote delivery, but a dual modal approach including remote and face-to-face delivery would optimize treatment efficacy. Educational support would be required to enable people living with dementia and their caregivers to overcome barriers relating to digital literacy.

Self-Reported Beneficial Effects of Chinese Calligraphy Handwriting Training for Individuals with Mild Cognitive Impairment: An Exploratory Study

BACKGROUND

Dementia is a common disease in aging populations. The treatment has mainly focused on memory decline prevention and behavior control. Nonpharmacological treatments, such as cognition training, physical exercise, and music therapy have been effective in slowing memory decline. Chinese calligraphy handwriting (CCH) through breath regulation and fine hand control involves high concentration levels, emotion regulation, and self-awareness. CCH is a mind and body activity that is culturally relevant to older Chinese adults. This study evaluated the beneficial effects of CCH on mild cognitive impairment.

METHODS

In 2018, we conducted 8 weeks of CCH training at the Tri-Service General Hospital. The participants were asked to copy a regular script. At the end of the course, they gave oral presentations and showed their work. Self-report questionnaires on emotion, memory, upper limb coordination, attention, and language were collected before and after training.

RESULTS

The five questionnaires showed significantly positive feelings after CCH training. The conditions of emotional stability, concentration, hand movement, memory, and speech improved.

CONCLUSIONS

CCH training stimulated the brain and improved cognition, psychological symptoms, and hand stability. It is inexpensive and worthwhile for elderly Chinese individuals with mild cognitive impairment to take time daily to practice calligraphy.

Effects of a Physical Activity Program that Incorporates Exercises Targeting Balance, Strength, and Proprioception on Cognitive Functions and Physical Performance in Old Adults with Mild Cognitive Impairment

BACKGROUND

Aging often leads to cognitive function decline, sensory structure deterioration, and musculoskeletal system weakening. This impacts postural control during static and dynamic activities like walking, increasing the fall risk among the elderly. Older adults with mild cognitive impairment (MCI) face an elevated fall risk and cognitive decline, magnifying the public health concern.

OBJECTIVE

This study aimed to explore solutions by investigating the effects of a multi-component physical activity program on cognitive and motor functions in MCI patients.

METHODS

Twenty-three participants were enrolled in the study and assigned into two groups: an intervention group (n = 13; age = 85.7±5.5 years) and a control group (n = 9; age = 85±6.7 years). The study spanned two months, with participants engaging in three 60-minute weekly physical exercise sessions. The intervention focused on improving proprioception, muscle strength, and balance.

RESULTS

Results demonstrated significant enhancements in physical performance, fall risk reduction, and balance (p < 0.05). Various tests, including the timed up and go test, Unipedal Stance test, Tinetti test, Short Physical Performance Battery, and 6-minute walking test, indicated these improvements. Cognitive function was evaluated with the Mini-Mental State Examination, revealing non-significant progress (p > 0.05). Predictive models for outcomes were developed using linear regression analysis during the follow-up stage.

CONCLUSIONS

This study underscores the effectiveness of a multi-component physical activity program encompassing balance, proprioception, and muscle-strengthening exercises as a non-pharmaceutical approach in improving balance skills and playing a key role in mitigating the risk of falls among old adults with MCI.

The Effect of Exercise on Falls in People Living with Dementia: A Systematic Review

BACKGROUND

People living with dementia (PWD) are at a heightened risk for falls. However, the effects of exercise on falls in PWD are unclear.

OBJECTIVE

To conduct a systematic review of randomized controlled trials (RCTs) examining the efficacy of exercise to reduce falls, recurrent falls, and injurious falls relative to usual care among PWD.

METHODS

We included peer-reviewed RCTs evaluating any exercise mode on falls and related injuries among medically diagnosed PWD aged ≥55years (international prospective register of systematic reviews (PROSPERO) ID:CRD42021254637). We excluded studies that did not solely involve PWD and were not the primary publication examining falls. We searched the Cochrane Dementia and Cognitive Improvement Group's Specialized Register and grey literature on 08/19/2020 and 04/11/2022; topical categories included dementia, exercise, RCTs, and falls. We evaluated the risk of bias (ROB) using the Cochrane ROB Tool-2 and study quality using the Consolidated Standards of Reporting Trials.

RESULTS

Twelve studies were included (n = 1,827; age = 81.3±7.0 years; female = 59.3%; Mini-Mental State Examination = 20.1±4.3 points; intervention duration = 27.8±18.5 weeks; adherence = 75.5±16.2%; attrition = 21.0±12.4%). Exercise reduced falls in two studies [Incidence Rate Ratio (IRR) range = 0.16 to 0.66; fall rate range: intervention = 1.35-3.76 falls/year, control = 3.07-12.21 falls/year]; all other studies (n = 10) reported null findings. Exercise did not reduce recurrent falls (n = 0/2) or injurious falls (n = 0/5). The RoB assessment ranged from some concerns (n = 9) to high RoB (n = 3); no studies were powered for falls. The quality of reporting was good (78.8±11.4%).

CONCLUSION

There was insufficient evidence to suggest that exercise reduces falls, recurrent falls, or injurious falls among PWD. Well-designed studies powered for falls are needed.

Fun and a meaningful routine: the experience of physical activity in people with dementia

Background

Physical activity is important to health and wellbeing. People with dementia are less physically active than their cognitively healthy counterparts. Reasons for this are multifaceted, and are thought to be social, psychological, and physiological. People with dementia often use services such as home care, day care centres and nursing home, and according to the stage of disease they are less or more dependent on other people to take part in activities. To develop appropriate services to this patient group, their needs and preferences regarding physical activity must be recognized. The aim of the study was therefore to provide insight into experiences with physical activity in people with dementia.

Methods

The current study is part of a larger research project on needs in people with dementia. The main project included qualitative semi-structured interviews with 35 persons with dementia. 27 of the participants talked about their experience with physical activity. In the current study, the relevant findings on this theme were analysed separately. A phenomenological hermeneutic research design was applied.

Results

The analysis revealed three main categories regarding experiences with physical activity. To be physically active provided positive experiences such as feelings of mastering and post-exercise euphoria. To be physically active was meaningful. The daily walk was an important routine to many, and it gave meaningful content to the day. Keeping up with activities confirmed identity. Lastly, to be active was perceived as challenging. Participants described different barriers to being physically active such as a decline of physical function, lack of motivation and being dependent on others to go out.

Conclusions

Many of the participants expressed that being physically active was important to them. It is essential that informal and formal carers are aware of the role physical activity plays in the lives of many people with dementia, so that appropriate measures can be taken to assure continued active living in order to preserve health and quality of life.

Effects of Chronic Physical Exercise or Multicomponent Exercise Programs on the Mental Health and Cognition of Older Adults Living in a Nursing Home: A Systematic Review of Studies From the Past 10 Years

Some nursing homes for the elderly provide holistic care that integrates several interventions, including physical exercise. The aim of this systematic review is to summarize the effects of physical exercise or multicomponent exercise programs on the mental health (wellbeing, anxiety and depression) and cognitive functions of older adults with/without dementia who live in a nursing home and do/do not require wheelchair assistance. To this end, PubMed, PsycInfo and Web of Science are using to identify clinical trials and randomized controlled studies conducted during the period January 2011 to December 2021 to examine the progression of research in this field over the past ten years. In total, 2597 articles are identifying and 21 are including in the systematic review. After selecting articles according to the PRISMA standards, the data extraction and methodological quality assessment of the eligible studies are performing individually by two reviewers and then pooled together. The synthesis of the studies shows that physical exercise or multicomponent exercise programs have a beneficial effect on mental health and cognitive functions. However, this effect is more common among older adults without dementia, compared to their counterparts who have dementia or use wheelchairs. The explanatory mechanisms, lack of benefits from physical exercise and the need to standardize methods are discussing in this regard. Finally, future studies must examine the effects of an innovative and adaptive physical activity program on the mental health and cognitive functions of older adults living in nursing homes.

Types of exercise and training duration on depressive symptoms among older adults in long-term care facilities

BACKGROUND

Depression is associated with a greater risk of disability, cognitive impairment, and suicide. Older adults in long-term care facilities (LTCFs) are more likely to develop depression due to changes in family roles and separation from family members. The aim of this study was to synthesize and analyze the effects of different types of exercise and training duration on depressive symptoms of older adults in LTCFs.

METHODS

Relevant peer-reviewed journal articles published in English were identified through a search of six electronic databases up to June 2021.

RESULTS

A total of 25 studies were included in the systematic review and 22 in the meta-analysis. The results of meta-analysis showed that exercise interventions reduced depression in cognitively intact older adults and in cognitively impaired older adults. Both exercising less than 150 min per week or more than 150 min per week, reduced depressive symptoms of older adults. In terms of exercise types, mind-body exercises, exergames, and strength training reduced depressive symptoms.

CONCLUSION

Exercise has a positive effect on reducing depressive symptoms with mind-body exercises, exergames, and strength training producing the best effect. Regardless of cognitive impairment, older adults in LTCFs benefited from exercise in reducing depressive symptoms.

Physical and Motor Fitness Tests for Older Adults Living in Nursing Homes: A Systematic Review

This systematic review aimed to identify the physical/motor fitness tests for nursing home residents and to examine their psychometric properties. Electronic databases were searched for articles published between January 2005 and October 2021 using MeSh terms and relevant keywords. Of the total of 4196 studies identified, 3914 were excluded based on title, abstracts, or because they were duplicates. The remaining 282 studies were full-text analyzed, and 41 were excluded, resulting in 241 studies included in the review. The most common physical component assessed was muscle strength; 174 (72.2%) studies assessed this component. Balance (138 studies, 57.3%) and agility (102 studies, 42.3%) were the second and third components, respectively, most widely assessed. In this review, we also describe the most used assessment tests for each physical/motor component. Some potentially relevant components such as manual dexterity and proprioception have been little considered. There are few studies assessing the psychometric properties of the tests for nursing home residents, although the data show that, in general, they are reliable. This review provides valuable information to researchers and health-care professionals regarding the physical/motor tests used in nursing home residences, helping them select the screening tools that could most closely fit their study objectives.

The Effects of High-Intensity Functional Training on Cognition in Older Adults with Cognitive Impairment: A Systematic Review

(1) Background: High-Intensity Functional Training (HIFT) is a new exercise modality that emphasizes multi-joint functional movements adaptable to any fitness level and promotes greater muscle recruitment. Previous studies have evaluated the positive effects of HIFT on mental and cognitive health but have not evaluated it in older people. This study aims to conduct a systematic review of randomized controlled trials assessing the effects of HIFT on general cognition in older adults with cognitive impairment. (2) Methods: Following the PRISMA 2020 guideline, articles that did a high-intensity functional physical exercise intervention on cognitive performance in older adults with mild to moderate cognitive impairment (MMSE > 10) or dementia, aged 55 years or older, published between 2011 and 2021 in five different electronic databases: PubMed, Web of Science, Scopus, CINAHL, and Cochrane plus were included. (3) Results: 7 articles were included, all having general cognition as their primary outcome. All assessed general cognition using the Mini-Mental State Examination, the ADAS-Cog, or both. All studies had at least one HIFT experimental group with a frequency of 2 sessions per week and a variable duration between protocols of 12, 13, 16, and 26 weeks. Two articles showed that a progressive HIFT program improves general cognition, four articles showed no significant changes within or between groups and one article concluded that a HIFT intervention does not slow cognitive decline. (4) Conclusions: Evidence exists of the benefits of HIFT on general cognition in older adults with cognitive impairment, assessed using the MMSE, the ADAS-cog, or both. Two articles that showed improvement in cognitive function used progressive HIFT with 80% RM at 6, 12, and 1 weeks; however, in the other articles, due to the heterogeneity of intervention protocols, measurement time points, and control group activities, mixed results were evidenced

The perceptions, needs and preferences of informal caregivers of nursing home residents with dementia regarding physical therapy: A qualitative study

INTRODUCTION

Informal caregivers often support nursing home residents with dementia in making therapeutic decisions. We explored the perceptions, needs and preferences of informal caregivers of nursing home residents with dementia regarding physical therapy.

METHOD

We conducted eleven semi-structured interviews. Thematic analysis was used.

RESULTS

Five themes emerged: 1) visibility and familiarity; 2) communication; 3) aim and content; 4) dosage and location; 5) level of expertise and the role of the physical therapist within the interdisciplinary team. Informal caregivers' perceptions of physical therapy included a lack of visibility and familiarity. They needed more communication, and empathic communication skills of the physical therapists. Preferences included physical therapy to be enjoyable, accessible and tailored to the needs of the resident.

CONCLUSION

Physical therapists need to involve informal caregivers in physical therapy care. Implementing shared decision-making will help to get informal caregivers more involved, but has yet to be studied in this setting.

Apathy as a Treatment Target in Alzheimer's Disease: Implications for Clinical Trials

Apathy is one of the most prevalent, stable and persistent neuropsychiatric symptom across the neurocognitive disorders spectrum. Recent advances in understanding of phenomenology, neurobiology and intervention trials highlight apathy as an important target for clinical intervention. We conducted a comprehensive review and critical evaluation of recent advances to determine the evidence-based suggestions for future trial designs. This review focused on 4 key areas: 1) pre-dementia states; 2) assessment; 3) mechanisms/biomarkers and 4) treatment/intervention efficacy. Considerable progress has been made in understanding apathy as a treatment target and appreciating pharmacological and non-pharmacological apathy treatment interventions. Areas requiring greater investigation include: diagnostic procedures, symptom measurement, understanding the biological mechanisms/biomarkers of apathy, and a well-formed approach to the development of treatment strategies. A better understanding of the subdomains and biological mechanisms of apathy will advance apathy as a treatment target for clinical trials.

Exercise Dosage in Reducing the Risk of Dementia Development: Mode, Duration, and Intensity-A Narrative Review

Senile dementia, also known as dementia, is the mental deterioration which is associated with aging. It is characterized by a decrease in cognitive abilities, inability to concentrate, and especially the loss of higher cerebral cortex function, including memory, judgment, abstract thinking, and other loss of personality, even behavior changes. As a matter of fact, dementia is the deterioration of mental and intellectual functions caused by brain diseases in adults when they are mature, which affects the comprehensive performance of life and work ability. Most dementia cases are caused by Alzheimer’s disease (AD) and multiple infarct dementia (vascular dementia, multi-infarct dementia). Alzheimer’s disease is characterized by atrophy, shedding, and degenerative alterations in brain cells, and its occurrence is linked to age. The fraction of the population with dementia is smaller before the age of 65, and it increases after the age of 65. Since women live longer than men, the proportion of women with Alzheimer’s disease is higher. Multiple infarct dementia is caused by a cerebral infarction, which disrupts blood supply in multiple locations and impairs cerebral cortex function. Researchers worldwide are investigating ways to prevent Alzheimer’s disease; however, currently, there are no definitive answers for Alzheimer’s prevention. Even so, research has shown that we can take steps to reduce the risk of developing it. Prospective studies have found that even light to moderate physical activity can lower the risk of dementia and Alzheimer’s disease. Exercise has been proposed as a potential lifestyle intervention to help reduce the occurrence of dementia and Alzheimer’s disease. Various workout modes will be introduced based on various physical conditions. In general, frequent exercise for 6–8 weeks lessens the risk of dementia development.

The Prognostic Impact of Hospital Transfer after Admission due to Acute Heart Failure

The prognostic impact of transfer to another hospital among acute heart failure (AHF) patients has not been well elucidated.Of the 800 AHF patients analyzed, 682 patients were enrolled in this study for analysis. The subjects were divided into two groups according to their discharge location: discharge home (Group-H, n = 589) or transfer to another hospital for rehabilitation (Group-T, n = 93). The Kaplan-Meier curves revealed a poorer prognosis, including all-cause death and heart failure (HF) events (death, readmission-HF), in Group-T than that in Group-H (P < 0.001, respectively). A multivariate Cox regression model showed that Group-T was an independent predictor of 365-day all-cause death (hazard ratio: 2.618, 95% confidence interval [CI]: 1.510-4.538, P = 0.001). The multivariate logistic regression analysis showed that aging (per 1-year-old increase, odds ratio [OR]: 1.056, 95% CI: 1.028-1.085, P < 0.001), female gender (OR: 2.128, 95% CI: 1.287-3.521, P = 0.003), endotracheal intubation during hospitalization (OR: 2.074, 95% CI: 1.093-3.936, P = 0.026), and increased Controlling Nutritional Status score on admission (per 1.0-point increase, OR: 1.247, 95% CI: 1.131-1.475, P < 0.001) were associated with transfer to another hospital after AHF admission. The prognosis, including all-cause death, was determined to be significantly poorer in patients who were transferred to another hospital, as their activities of daily living were noted to lessen before discharge (n = 11) compared to others (n = 82).Elderly AHF patients suffering from malnutrition were difficult to discharge home after AHF admission, and transfer to another hospital only led to adverse outcomes. Appropriate rehabilitation during definitive hospitalization appears necessary for managing elderly patients in the HF pandemic era.

Physical exercise as a non-pharmacological strategy for reducing behavioral and psychological symptoms in elderly with mild cognitive impairment and dementia: a systematic review of randomized clinical trials

BACKGROUND

Elderly people with dementia may exhibit behavioral and psychological symptoms throughout the course of disease. Non-pharmacological therapies, such as regular physical activity, are considered strategies for managing these symptoms.

OBJECTIVE

The aim of this study was to investigate whether participation in physical exercise programs is effective in reducing behavioral and neuropsychiatric symptoms in elderly people with Mild Cognitive Impairment (MCI) and dementia.

METHODS

A literature review was carried out in MEDLINE (PubMed), SciELO, Web of Science, Scopus and SPORTDiscus databases from 2010 to 2020. The eligible studies were randomized clinical trials involving elderly people with mild cognitive impairment or dementia and assessing changes in neuropsychiatric and psychological symptoms as primary or secondary outcomes. The studies had a group with only physical exercise as an intervention compared to a control group.

RESULTS

Of 175 publications identified in the initial survey, only 7 studies met the eligibility criteria. Four out of 7 studies demonstrated positive effects in reducing behavioral symptoms, while the others did not report differences between gains according to the type of protocol.

CONCLUSIONS

Moderate to intense aerobic and muscle strengthening exercises may have a potential benefit in the management of behavioral and psychological symptoms in dementia, but studies varied in their conclusions. This review indicates the need for further intervention studies to investigate, as a primary outcome, the absolute effect of physical exercise and its impact on behavioral and psychological symptoms in elderly people with MCI dementia, especially in the early stages of the disease.

Re-thinking reablement strategies for older adults in residential aged care: a scoping review

BACKGROUND

The number of older adults in residential aged care is increasing. Aged care residents have been shown to spend most of the day sedentary and have many co-morbidities. This review aimed to systematically explore the effectiveness of reablement strategies in residential aged care for older adults' physical function, quality of life and mental health, the features of effective interventions and feasibility (compliance, acceptability, adverse events and cost effectiveness).

METHOD

This scoping review was undertaken according to PRISMA guidelines (extension for scoping reviews). Five e-databases (Medline, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and CINAHL) were searched from 2010 onwards. Randomised controlled trials investigating reablement strategies addressing physical deconditioning for older adults (mean age ≥ 65 yrs) in residential aged care on physical function, quality of life or mental health were included. Feasibility of the interventions (compliance, acceptability, satisfaction, adverse events and cost effectiveness) was explored.

RESULTS

Five thousand six hundred thirty-one citations were retrieved, and 63 studies included. Sample sizes ranged from 15 to 322 and intervention duration from one to 12 months. Exercise sessions were most often conducted two to three times per week (44 studies) and physiotherapist-led (27 studies). Interventions were predominately multi-component (28 studies, combinations of strength, balance, aerobic, functional exercises). Five interventions used technology. 60% of studies measuring physical function reported significant improvement in the intervention versus control, 40% of studies measuring quality of life reported significant improvements in favour of the intervention, and 26% of studies measuring mental health reported significant intervention benefits. Over half of the studies measured compliance and adverse events, four measured acceptability and none reported cost effectiveness.

CONCLUSIONS

There has been a research surge investigating reablement strategies in residential aged care with wide variability in the types and features of strategies and outcome measures. Few studies have measured acceptability, or cost effectiveness. Exploration of core outcomes, mapping stakeholders and co-designing a scalable intervention is warranted.

Degree of personalisation in tailored activities and its effect on behavioural and psychological symptoms and quality of life among people with dementia: a systematic review and meta-analysis

OBJECTIVES

To understand and assess the degree of personalisation of tailored activities for people with dementia (PWD); and to estimate the magnitude of the effects of levels of personalisation on reducing behavioural and psychological symptoms of dementia (BPSD), improving quality of life (QoL) and level of engagement.

DESIGN

Systematic review with meta-analysis.

DATA SOURCES

ProQuest, PubMed, Ovid, Cochrane Library, Web of Science and CINAHL were searched from the start of indexing to May 2020.

ELIGIBILITY CRITERIA

We included randomised controlled trials and quasi-experimental studies assessing the effects of tailored activities for people aged 60 years or older with dementia or cognitive impairment on the outcomes of BPSD, QoL, depression and level of engagement with control groups.

DATA EXTRACTION AND SYNTHESIS

Two researchers screened studies, extracted data and assessed risks of bias. A rating scheme to assess the degree of personalisation of tailored activities was developed to classify tailored activities into high/medium/low groups. Effect sizes were expressed using standardised mean differences at 95% Confidence Interval (CI). Subgroup analyses were conducted to assess whether the degree of personalisation of tailored activities affected outcomes of interest.

RESULTS

Thirty-five studies covering 2390 participants from 16 countries/regions were identified. Studies with a high-level of personalisation interventions (n=8) had a significant and moderate effect on reducing BPSD (standardised mean differences, SMD=-0.52, p<0.05), followed by medium (n=6; SMD=-0.38, p=0.071) and low-level personalisation interventions (n=6; SMD=-0.15, p=0.076). Tailored activities with a high-level of personalisation had a moderate effect size on improving QoL (n=5; SMD=0.52, p<0.05), followed by a medium level (n=3; SMD=0.41, p<0.05) of personalisation.

CONCLUSIONS

To develop high-level tailored activities to reduce BPSD and improve QoL among PWD, we recommend applying comprehensive assessments to identify and address two or more PWD characteristics in designed tailored activities and allow modification of interventions to respond to changing PWD needs/circumstances.

Physical Exercise and Mental Health: The Routes of a Reciprocal Relation

Sport participation and exercise practice are considered to be beneficial for mental status, yielding an improved mood and better quality of life. On the other hand, good mental fitness is thought to lead to better physical status and sport performance. The key aim of this narrative review is to provide an unstructured overview on the topic with special considerations on the role of mental and physical health to summarize the evidence on their reciprocal influence. While very few papers describe the role of mental health measures in affecting physical performance, more evidence is available concerning the effect of exercise and sport in improving mental health outcomes. Furthermore, there is a consistent role of depressive and anxiety symptoms in influencing the risk of sport injury in either recreational or elite athletes. Moreover, the importance of investigating mental health issues in elite and retired athletes is highlighted. On the basis of the available literature, several biases were found to affect the provided evidence mainly because of the complexity of a proper study design in this field.

Physical exercise and goal attainment after shunt surgery in idiopathic normal pressure hydrocephalus: a randomised clinical trial

Background

Rehabilitation in iNPH is suggested to be an important factor to improve patients’ functions but there are lack of clinical trials evaluating the effect of rehabilitation interventions after shunt surgery in iNPH. The objective of this study was to evaluate the effect of a physical exercise programme and goal attainment for patients with idiopathic normal pressure hydrocephalus (iNPH) after surgery compared to a control group.

Methods

This was a dual centre randomised controlled trial with assessor blinding, intention-to-treat (ITT) and per protocol (PP) analysis. Individuals diagnosed with iNPH scheduled to undergo shunt surgery at the Linköping University Hospital in Linköping and Sahlgrenska University Hospital in Gothenburg, Sweden were consecutively eligible for inclusion. Inclusion was conducted between January 2016 and June 2018. The patients were randomised 1:1 using sequentially numbered sealed envelopes to receive either written exercise information (control group) or written information and an additional supervised high-intensity, functional exercise programme (HIFE) executed twice weekly over 12 weeks (exercise group). Preoperatively, the patients set individual goals. The primary outcome was change from baseline in the total iNPH scale score at the post-intervention follow-up. Secondary outcomes were goal attainment, and change in the separate scores of gait, balance, neuropsychology and continence and in the total score after 6 months.

Results

In total, 127 participants were randomised to the exercise group (n = 62) and to the control group (n = 65). In the ITT population (exercise group, n = 50; control group, n = 59), there were no between-group differences in the primary outcome, but the attrition rate in the exercise group was high. The exercise group improved more than the control group in the balance domain scores after 6 months. Post-intervention, the PP exercise population achieved their set goals to a greater extent than the controls.

Conclusions

An additional effect of the 12-week HIFE-programme on the overall improvement according to the iNPH-scale after shunt surgery in iNPH was not shown. This could be due to high attrition rate. However, the long-term effect on balance and higher goal achievement indicate beneficial influences of supervised physical exercise.

A multicomponent psychosocial intervention among people with early-stage dementia involving physical exercise, cognitive stimulation therapy, psychoeducation and counselling: Results from a mixed-methods study

BACKGROUND

There is increasing awareness of the benefits of both physical and psychosocial interventions to empower and benefit people with dementia and their caregivers. However, the potential additional benefits of combining physical and psychosocial interventions have only been sparsely explored. The aim of this pilot study was to investigate the acceptability and potential impact of a multicomponent intervention comprising physical exercise, cognitive stimulation therapy (CST), psychoeducation and counselling for people with early-stage dementia.

DESIGN

A 15-week multicomponent group-based intervention was offered to people with early-stage dementia in Denmark (N = 44). A mixed-methods design combining interviews, observations, tests of cognitive and physical functioning and an interviewer-assisted questionnaire on quality of life was applied to (1) investigate acceptability of the intervention, including whether people with dementia and their caregivers found the intervention meaningful and (2) to explore and assess changes in participants' physical and cognitive functioning and quality of life. The study was conducted between June 2018 and August 2019.

RESULTS

The pilot study demonstrated that the multicomponent intervention was acceptable for people with early-stage dementia and their caregivers. Test results did not show significant changes in measures of participants' physical and cognitive functioning or quality of life. However, qualitative data revealed that participants perceived the intervention as meaningful and found that it had a positive influence on their physical and social well-being. In addition, interaction and support from peers and staff members was considered important and rewarding.

CONCLUSION

This multicomponent intervention constitutes a meaningful and beneficial activity for people with early-stage dementia and their caregivers. It provides an opportunity to engage in social interactions with peers and experience professional support. The study also underlines the importance of providing prolonged and sustainable interventions for people with dementia to maintain personal and social benefits.

Screening of apathetic elderly adults using kinematic information in gait and sit-to-stand/stand-to-sit movements measured with Doppler radar

This paper presents a Doppler radar apathy-screening technique applied to elderly people based on their basic daily activities of walking and movements of sit-to-stand and stand-to-sit (STS). Our Doppler radar system remotely measured the kinematic parameters of the movements of 78 community-dwelling elderly adults (27 apathetic participants and 51 non-apathetic ones). Subsequently, logistic regression models using the measured kinematic parameters of gait and sit-to-stand/stand-to-sit movements were constructed for screening. The experimental results verified that, although the model using gait parameters could screen an apathetic group with a sensitivity of 85.2% and a specificity of 58.8%, the model using the STS parameters achieved better screening accuracies with a sensitivity of 88.9% and a specificity of 76.5%. These results reveal that the kinematic information of STS movements is significantly more effective at detecting apathy than is the gait information, which is otherwise regarded to be effective in conventional epidemiological studies.

Brain-based mechanisms of late-life depression: Implications for novel interventions

Late-life depression (LLD) is a particularly debilitating illness. Older adults suffering from depression commonly experience poor outcomes in response to antidepressant treatments, medical comorbidities, and declines in daily functioning. This review aims to further our understanding of the brain network dysfunctions underlying LLD that contribute to disrupted cognitive and affective processes and corresponding clinical manifestations. We provide an overview of a network model of LLD that integrates the salience network, the default mode network (DMN) and the executive control network (ECN). We discuss the brain-based structural and functional mechanisms of LLD with an emphasis on their link to clinical subtypes that often fail to respond to available treatments. Understanding the brain networks that underlie these disrupted processes can inform the development of targeted interventions for LLD. We propose behavioral, cognitive, or computational approaches to identifying novel, personalized interventions that may more effectively target the key cognitive and affective symptoms of LLD.

Home/community-based interventions to improve function in persons with mild cognitive impairment/early dementia

Persons with mild cognitive impairment/early dementia have a possible 20-year trajectory of disability and dependence with little information on the effectiveness of interventions to improve function. This review investigates the literature of home/community-based interventions for physical and executive function in persons with mild cognitive impairment/early dementia. A 2007-2020 systematic literature search was conducted through PubMed, CINAHL Plus with Full Text and PsycINFO. Of the 1749 articles retrieved, 18 eligible studies were identified and consisted of three types of interventions: cognitive training-only (n = 7), multicomponent (n = 9), and physical activity-only (n = 2). Results showed that the interventions impacting function in persons with cognitive impairment incorporated a visual/written element, technology-based training, caregiver support, and modified duration/increased frequency of interventions. In studies improving function, participants simulated Instrumental Activities of Daily Living. They addressed cognitive function using both objective and subjective cognitive measures. We found gaps in the literature in incorporating race/ethnicity and appropriate socioeconomic status measures.

Models of provider care in long-term care: A rapid scoping review

INTRODUCTION

One of the current challenges in long-term care homes (LTCH) is to identify the optimal model of care, which may include specialty physicians, nursing staff, person support workers, among others. There is currently no consensus on the complement or scope of care delivered by these providers, nor is there a repository of studies that evaluate the various models of care. We conducted a rapid scoping review to identify and map what care provider models and interventions in LTCH have been evaluated to improve quality of life, quality of care, and health outcomes of residents.

METHODS

We conducted this review over 10-weeks of English language, peer-reviewed studies published from 2010 onward. Search strategies for databases (e.g., MEDLINE) were run on July 9, 2020. Studies that evaluated models of provider care (e.g., direct patient care), or interventions delivered to facility, staff, and residents of LTCH were included. Study selection was performed independently, in duplicate. Mapping was performed by two reviewers, and data were extracted by one reviewer, with partial verification by a second reviewer.

RESULTS

A total of 7,574 citations were screened based on the title/abstract, 836 were reviewed at full text, and 366 studies were included. Studies were classified according to two main categories: healthcare service delivery (n = 92) and implementation strategies (n = 274). The condition/ focus of the intervention was used to further classify the interventions into subcategories. The complex nature of the interventions may have led to a study being classified in more than one category/subcategory.

CONCLUSION

Many healthcare service interventions have been evaluated in the literature in the last decade. Well represented interventions (e.g., dementia care, exercise/mobility, optimal/appropriate medication) may present opportunities for future systematic reviews. Areas with less research (e.g., hearing care, vision care, foot care) have the potential to have an impact on balance, falls, subsequent acute care hospitalization.

Exploring life-space in the nursing home. An observational longitudinal study

BACKGROUND

Traditional performance-based measurements of mobility fail to recognize the interaction between the individual and their environment. Life-space (LS) forms a central element in the broader context of mobility and has received growing attention in gerontology. Still, knowledge on LS in the nursing home (NH) remains sparse. The aim of this study was to identify LS trajectories in people with dementia from time of NH admission, and explore characteristics associated with LS over time.

METHODS

In total, 583 people with dementia were included at NH admission and assessed biannually for 3 years. LS was assessed using the Nursing Home Life-Space Diameter. Association with individual (age, sex, general medical health, number of medications, pain, physical performance, dementia severity, and neuropsychiatric symptoms) and environmental (staff-to-resident ratio, unit size, and quality of the physical environment) characterises was assessed. We used a growth mixture model to identify LS trajectories and linear mixed model was used to explore characteristics associated with LS over time.

RESULTS

We identified four groups of residents with distinct LS trajectories, labelled Group 1 (n = 19, 3.5%), Group 2 (n = 390, 72.1%), Group 3 (n = 56, 10.4%), Group 4 (n = 76, 14.0%). Being younger, having good compared to poor general medical health, less severe dementia, more agitation, less apathy, better physical performance and living in a smaller unit were associated with a wider LS throughout the study period.

CONCLUSION

From NH admission most NH residents' LS trajectory remained stable (Group 2), and their daily lives unfolded within their unit. Better physical performance and less apathy emerged as potentially modifiable characteristics associated with wider LS over time. Future studies are encouraged to determine whether LS trajectories in NH residents are modifiable, and we suggest that future research further explore the impact of environmental characteristics.

Suicide among Older Adults with Dementia: Effects of Korea's Long-Term Care Insurance System

South Korea recently expanded its coverage rate of long-term care insurance (LTCI) by adding a “dementia special grade” in 2014 to improve care service accessibility and extend health life for older adults with dementia. In this study, we propose a multifaceted policy to reduce the suicide risk among older adults with dementia by evaluating the effectiveness of using the long-term care services (LTCS). A sample of 62,282 older adults was selected from the “Older Adults Cohort DB” of the National Health Insurance Service. We conducted Kaplan–Meier and Cox regression to represent the yearly survival curve from 2002 to 2015 according to the individual characteristics. Difference-in-difference estimation was conducted to identify the effect of LTCS on suicide rates by using LTCS before and after 2014. The suicide risk of older adults using LTCS was about 0.256-times lower than those who did not use it (OR = 0.296, 95% CI = 0.183–0.478), whereas it increased after the expansion of the dementia grading (OR = 2.131, 95% CI = 1.061–4.280). To prevent the risk of suicide among older adults with dementia, not only did the mortality rate vary depending on the sex, activities of daily living (ADL), and type of caregiver at the individual level but appropriate national intervention and management, such as improving the accessibility of LTCS, are also needed.

Diagnostic criteria for apathy in neurocognitive disorders

INTRODUCTION

Apathy is common in neurocognitive disorders (NCD) but NCD-specific diagnostic criteria are needed.

METHODS

The International Society for CNS Clinical Trials Methodology Apathy Work Group convened an expert group and sought input from academia, health-care, industry, and regulatory bodies. A modified Delphi methodology was followed, and included an extensive literature review, two surveys, and two meetings at international conferences, culminating in a consensus meeting in 2019.

RESULTS

The final criteria reached consensus with more than 80% agreement on all parts and included: limited to people with NCD; symptoms persistent or frequently recurrent over at least 4 weeks, a change from the patient's usual behavior, and including one of the following: diminished initiative, diminished interest, or diminished emotional expression/responsiveness; causing significant functional impairment and not exclusively explained by other etiologies.

DISCUSSION

These criteria provide a framework for defining apathy as a unique clinical construct in NCD for diagnosis and further research.

Exercise effects on backward walking speed in people with dementia: A randomized controlled trial

BACKGROUND

Multidirectional walking, including backward walking, is integral to daily activities, and seems particularly challenging in older age, and in people with pathology affecting postural control such as dementia.

RESEARCH QUESTION

Does exercise influence backward walking speed in people with dementia, when tested using habitual walking aids and without, and do effects differ according to walking aid use?

METHODS

This study included 141 women and 45 men (mean age 85 years) with dementia from the Umeå Dementia and Exercise (UMDEX), a cluster-randomized controlled trial study set in 16 nursing homes in Umeå, Sweden. Participants were randomized to a High-Intensity Functional Exercise (HIFE) program targeting lower limb strength-, balance and mobility exercise or to a seated attention control activity. Blinded assessors measured 2.4-meter usual backward walking speed, at baseline, 4 - (intervention completion) and 7-month follow-up; tested 1) with habitual walking aids allowed, and 2) without walking aids.

RESULTS

Linear mixed models showed no between-group effect in either backward walking speed test at 4 or 7 months; test 1) 0.005 m/s, P = .788 and -0.006 m/s, P = .754 and test 2) 0.030 m/s, P = .231 and 0.015 m/s, P = .569, respectively. In interaction analyses, exercise effects differed significantly between participants who habitually walked unaided compared with those that used a walking aid at 7 months (0.094 m/s, P = .027).

SIGNIFICANCE

In this study of older people with dementia living in nursing homes, the effects of exercise had no overall effects on backwards walking speed. Nevertheless, some benefit was indicated in participants who habitually walked unaided, which is promising and merits further investigation in future studies.

[Physical activity and activities of daily living of nursing homes residents: A systematic review and meta-analysis]

BACKGROUND

Interventions to promote physical activity in nursing homes are among the priorities of German long-term care insurance funds. We summarized the evidence on the effectiveness of such interventions.

METHODS

We conducted a systematic literature search in five electronic databases in November 2019, which was complemented by searching reference lists and trials registries. Eligible studies included individually (RCTs) or cluster randomized trials or non-randomized comparative studies that investigated the effectiveness of interventions to promote physical activity in nursing home residents and their impact on the ability to perform activities of daily living. Results were synthesized using random effects meta-analysis.

RESULTS

Meta-analysis of 19 included studies with high risk of bias showed a small yet statistically significant effect on activities of daily living (SMD = 0.40, 95 % CI 0.08-0.72); heterogeneity was substantial (I² = 77 %, p < 0.0001). Sensitivity analysis excluding two non-randomized comparative studies did not alter the results (SMD = 0.40, 95 % CI 0.03-0.76). The effect attenuated but was still statistically significant in a meta-analysis which excluded five studies that were largely responsible for the heterogeneity (SMD = 0.27, 95 % CI 0.12-0.43, I²=34 %, p = 0.10). Subgroup analyses did not demonstrate any statistically significant results in favour of physical activity.

DISCUSSION

We found evidence for a beneficial effect on activities of daily living in favour of interventions that aim to promote physical activity. Due to the high overall risk of bias and substantial heterogeneity of the included studies the results should be interpreted with caution, though.

CONCLUSION

Methodologically sound studies are needed to strengthen the evidence base on the topic.

Tele-Rehabilitation for People with Dementia during the COVID-19 Pandemic: A Case-Study from England

Introduction: The Promoting Activity, Independence and Stability in Early Dementia (PrAISED) is delivering an exercise programme for people with dementia. The Lincolnshire partnership National Health Service (NHS) foundation Trust successfully delivered PrAISED through a video-calling platform during the Coronavirus Disease 2019 (COVID-19) pandemic. Methods: This qualitative case-study aimed to identify participants that video delivery worked for, to highlight its benefits and its challenges. Interviews were conducted between May and August 2020 with five participants with dementia and their caregivers (n = 10), as well as five therapists from the Lincolnshire partnership NHS foundation Trust. The interviews were analysed through thematic analysis. Results: Video delivery worked best when participants had a supporting caregiver and when therapists showed enthusiasm and had an established rapport with the client. Benefits included time efficiency of sessions, enhancing participants’ motivation, caregivers’ dementia awareness, and therapists’ creativity. Limitations included users’ poor IT skills and resources. Discussion: The COVID-19 pandemic required innovative ways of delivering rehabilitation. This study supports that people with dementia can use tele-rehabilitation, but success is reliant on having a caregiver and an enthusiastic and known therapist.

Pain-Reducing Effects of Physical Therapist-Delivered Interventions: A Systematic Review of Randomized Trials Among Older Adults With Dementia

BACKGROUND AND PURPOSE

Pain is common among older adults with dementia. There are nonpharmacological options for managing pain in this population. However, the effects of physical therapist-delivered interventions have not been summarized. The purpose of this systematic review was to summarize the literature on physical therapist-delivered interventions in randomized trials for reducing pain among older adults with dementia.

METHODS

A systematic search of MEDLINE/PubMed, CINAHL, PsycINFO, and Web of Science was conducted for randomized trials of pain management in individuals 60 years or older with medically diagnosed dementia of any severity. Included studies addressed the effects of nonpharmacological physical therapist-delivered interventions on pain outcomes. Pain outcomes included patient or caregiver self-report, observational or interactive measures. Independent reviewers extracted relevant data and assessed methodological quality using the PEDro scale.

RESULTS AND DISCUSSION

Three studies (total = 222 participants; mean age range = 82.2-84.0 years; 178 [80.2%] females) met inclusion criteria. PEDro scores ranged from 4 to 8/10. Interventions included passive movement and massage. Pain outcomes included the observational measures Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC), Pain in Advanced Dementia (PAINAD), and Doloplus-2 Scale. Passive movement did not show better results when compared with no treatment, while massage showed pain-reducing effects in 1 study compared with no treatment.

CONCLUSIONS

The evidence supporting pain-reducing physical therapy interventions for patients with dementia is limited. There is a clear gap in knowledge related to evidence-based physical therapy for managing pain in this population. Future studies should examine active physical therapist-delivered interventions and utilize interactive pain measures.

High-intensity exercise programs in people with dementia — a systematic review and meta-analysis

Dementia is a syndrome characterized by a progressive deterioration of cognitive and physical functions. The aim of this systematic review was to investigate the effects of high-intensity exercise training (HIT) programs on cognitive and mental health, physical performance, activities of daily living (ADLs) and quality of life (QoL) in people with dementia. A systematic literature search for randomized controlled trials was performed until July 2019. We calculated mean difference (MD) or standardized MD (SMD) and the 95% confidence interval (CI), and assessed heterogeneity using I2 statistic. Nine studies from three large-scale research projects which were based on the high-intensity functional exercise (HIFE) program incorporating strength, balance and mobility exercises of the lower limbs, including 456 participants (85.5 ± 7.0 years), were considered. There was an overall good study quality (mean PEDro score = 7.6 ± 0.7). Compared to seated control activities, strength and balance HIT resulted in statistically significant but small positive effects on balance performance (MD = 2.31, 95% CI = 0.44–4.17, p = 0.02; I2 = 73%) and on the abilities to independently perform ADLs (SMD = 0.28, 95% CI = 0.12–0.44, p = 0.0006; I2 = 0%). No differences were found in cognitive function, depressive symptoms and QoL. The qualitative analyses yielded sporadic beneficial results (mobility, psychological well-being and apathetic behaviour) in favour of HIT. There is only limited evidence for an intensity-related dose–response relationship. Further well-designed studies are needed to identify the best exercise type for different types and stages of dementia.

Balance and gait performance in older adults with early-stage cognitive impairment

BACKGROUND

People with cognitive impairment are susceptible to fall. Previous studies regarding balance and gait enrolled patients with various severity of dementia. Quantification of the balance and gait performance of people with cognitive impairment may help identify their postural instability and fall risks.

AIM

We investigated the differences in balance and gait among older adults with preserved cognition, amnestic mild cognitive impairment, and mild dementia due to Alzheimer's disease.

DESIGN

Prospective observational study.

SETTING

Outpatient department of neurology or psychology.

POPULATION

Older adults (aged ≥65 years) with independent gait were evaluated using the Mini-Mental State Examination and Clinical Dementia Rating scale. People with other neurological or musculoskeletal disorders were excluded.

METHODS

Participants were classified into three groups: 30 healthy controls, 30 mild cognitive impairment and 30 mild dementia. Balance were evaluated through functional test (Berg Balance Scale [BBS]) and laboratory test (posturography). Gait was assessed by wearable device. Muscle strength and mass were measured through grip force, calf circumstance, and body composition.

RESULTS

The BBS (P=0.04), posturography of fall risk index (FR, P=0.01) and sensory integration indices in eyes open and firm surface (EOFIS, P=0.009), eyes open and foam surface (EOFOS, P=0.003) were substantially different among three groups. EOFIS and EOFOS indices of balance in mild dementia were significantly worse than in MCI. The gait speed (P=0.04) and stride length (P=0.04) were significantly different among three groups. The post-hoc analyses revealed that all above balance and gait indices in subjects with cognitive impairments were significantly worse than in healthy controls. The grip force, calf circumstance and body composition-muscle mass did not significantly differ among three groups.

CONCLUSIONS

It is a piece of evidence that cognitive dysfunction, even in early stage of memory decline, may have some bad impact on balance and gait regardless of the effect of musculoskeletal problems.

CLINICAL REHABILITATION IMPACT

Understanding the difference of specific indices of balance and gait among different severity of cognitive impairments and healthy controls could help to develop better balance-oriented rehabilitation programs in older adults at early-stage cognitive impairment.

High-intensity functional exercise in older adults with dementia: A systematic review and meta-analysis

OBJECTIVE

This study aimed to investigate the efficacy of high-intensity functional exercise among older adults with dementia.

METHODS

In this systematic review and meta-analysis of randomized controlled trials, we collected articles published before August 2020 from PubMed, Embase, and the Cochrane Library to evaluate the effect of high-intensity functional exercise on older adults with dementia. Primary outcomes included improvements in balance function and gait performance (speed, cadence, and stride length). The secondary outcomes included lower limb strength, activities of daily living, psychiatric well-being, depression, and cognition. Furthermore, we performed subgroup analysis with two high-intensity functional exercise programs: the Umeå program and Hauer's program.

RESULTS

We identified 15 articles describing six trials including older adults with dementia undergoing high-intensity functional exercise or control activity. The meta-analysis indicated that high-intensity functional exercise, both in Hauer's program and in the Umeå program, significantly improved balance function (pooled standardized mean difference 0.57, 95% confidence interval 0.31-0.83). Hauer's program significantly improved gait speed, cadence, stride length, and lower limb strength. Beneficial effects on speed, cadence, and lower limb strength were retained for several months. The Umeå program facilitated activities of daily living and psychiatric well-being, with effects on activities of daily living lasting several months. In the only eligible trial, no effects on cognition were observed. Adverse effects of high-intensity functional exercise were minimal to none.

CONCLUSIONS

High-intensity functional exercise is generally safe and is recommended for older individuals with mild or moderate dementia to provide benefits in motor performance and daily functioning.

Neuroanatomical Abnormalities in Older Depressed Adults With Apathy: A Systematic Review

OBJECTIVE

Apathy is a common phenomenon in late-life depression and is associated with poor outcomes. Apathy is often unrecognized in older depressed adults, and efficacious treatment options are lacking. This review provides a systematic review of the neuroanatomical abnormalities associated with apathy in late-life depression. In addition, the review summarizes the neuroimaging findings from studies of neurodegenerative and focal brain injury conditions that frequently present with apathy. The goal is to elucidate cerebral network abnormalities that give rise to apathy in older adults with mood disturbances and to inform future treatment targets.

METHOD

Systematic literature review.

RESULTS

The few studies that have directly examined the neuroanatomical abnormalities of apathy in late-life depression suggest disturbances in the anterior cingulate cortex, insula, orbital and dorsal prefrontal cortex, striatum, and limbic structures (ie, amygdala, thalamus, and hippocampus). Studies examining the neuroanatomical correlates of apathy in other aging populations are consistent with the pattern observed in late-life depression.

CONCLUSIONS

Apathy in late-life depression appears to be accompanied by neuroanatomical abnormalities in the salience and reward networks. These network findings are consistent with that observed in individuals presenting with apathy in other aging-related conditions. These findings may inform future treatments that target apathy.
