Insomnia In Caregivers Of Persons With Dementia: Who Is At Risk And What Can Be Done About It?

Health effects of caregiving and coping with severe mental disorders: A caregivers' experience

Background

Informal caregivers are an essential health resource in the care of persons with severe mental disorders, particularly in South Africa where access to mental healthcare services is limited.

Aim

The study aimed to explore and describe the coping strategies used by informal caregivers and the specific health impacts they face in the context of severe mental disorders in South Africa.

Setting

The study was conducted in Bushbuckridge municipality situated in the northeastern parts of Mpumalanga province, South Africa.

Methods

A descriptive qualitative methodology was used to conduct semi-structured interviews with 12 purposefully selected participants. Audio-recorded interviews were translated, transcribed and analysed inductively on NVivo12 using reflexive thematic analysis.

Results

The themes identified were caregivers' experience of consequences of caregiving and caregivers' experience of coping with their caregiving role. Participants experienced negative consequences on their emotional, mental and physical health. The participants use internal and external resources to cope with the challenges they face, and many highlighted using emotion-focused coping strategies.

Conclusion

The findings revealed an urgent need to develop support strategies to strengthen informal caregivers' coping and promote good health particularly in rural South Africa where informal caregivers play a crucial role in the management of severe mental disorders.

Contribution

The finding demands that policymakers and healthcare providers prioritise the health and well-being of the informal caregivers. There should be policies targeted specifically at developing and implementing caregiver-orientated healthcare services.

Examining the Impact of Different Components of Sleep Quality on Anxiety Among Family Carers of People with Dementia

Existing interventions for family carers of people with dementia tend to be less effective for anxiety than for depression. Therefore, identifying factors affecting carer anxiety is important to inform future interventions. This study conducted 2 multiple regression analyses using a sample of 91 family carers. The first regression model (∆R² = .24), exploring the impact of demographic variables and carer stressors, demonstrated that hours of caring (β = .33) and overall sleep quality (β = .28) were significant predictors of anxiety. To further investigate the impact of sleep quality, the second model (∆R² = .24) focussed on exploring the differential impact of various components of sleep quality on anxiety. Findings demonstrated that subjective sleep quality (β = .33) and sleep disturbances (β = .22) were significant predictors. Hours of caring per week, subjective sleep quality and sleep disturbances seem to be critical for treating anxiety in family carers. Future studies should investigate whether targeting these variables could improve carer anxiety.

Supporting Caregivers of Veterans with Dementia

As the number of veterans with dementia continues to increase, support services for those veterans and their caregivers must also increase. Caregivers of veterans with dementia often report high levels of emotional distress in the form of anxiety, exhaustion, and burden that negatively impacts their health and quality of life. This brief descriptive report highlights a Veterans Health Administration (VHA) project in which a social worker trained in palliative care, teaches stress-reduction to caregivers through individual counseling and virtual groups. In two years, 39 caregivers received individual assessment and counseling focused on stress-reduction. Also, five group webinars were held on the topic of self-care that averaged 17 caregivers per group. 24 caregivers completed a survey and results suggested that stress-reduction and self-care may be viable target areas of intervention for caregivers of veterans with dementia in both individual and group formats. More research is needed in this area to improve our knowledge of how stress may be reduced for caregivers and what type of interventions may be effective to help caregivers reduce stress and improve their self-care.

Sleep disturbance in caregivers of individuals with Parkinsonism: a systematic review and meta-analysis

OBJECTIVES

The global prevalence of Parkinsonism continues to rise given ageing populations. Individuals with Parkinsonism who have moderate or severe symptoms typically require a high level of care, including assistance with activities of daily living. This care is often provided across the 24-hour period by a family member or friend. It is likely that providing care significantly impacts the sleep duration and quality of the caregiver given overnight caring responsibilities, in addition to worry and stress associated with the caregiving role. The aim of this systematic review and meta-analysis was to investigate whether providing care to an individual with Parkinsonism was associated with disturbed caregiver sleep, and to identify associated factors that may contribute to disturbed sleep in this population.

SETTING

Five databases were electronically searched on 30 June 2021 including CINAHL, PubMed, PsycINFO, CENTRAL and EMBASE.

PARTICIPANTS

Eligibility criteria included a population of caregivers whose care recipient has a form of Parkinsonism.

PRIMARY AND SECONDARY OUTCOME MEASURES

To be included in this systematic review, outcome measures of caregiver sleep (eg, sleep duration, sleep quality) were required.

RESULTS

Eighteen studies (n=1998) were included. Findings indicated that caregivers of individuals with Parkinsonism typically experience poor sleep quality (mean (95% CI): 5.6 (4.8 to 6.4) points on the Pittsburgh Sleep Quality Index), increased sleep latency and poor sleep efficiency.

CONCLUSIONS

The degree of poor sleep quality was clinically significant. However, further investigation of sleep outcomes is required using sleep measurement tools tailored for this population (eg, measures that capture overnight sleep disruption by care recipient/s). Additionally, there is a need for appropriate individual and societal-level interventions to improve caregiver sleep.

Daily Sleep and Anxious and Depressive Symptoms among Dementia Caregivers - The Mediation of Cortisol Total Output on High- and Low-stress Days

OBJECTIVES

Dementia family caregivers report poor sleep and mood, typically attributed to chronic stress and managing frequent daily stressors. While many studies use global retrospective reports of these indicators, the current study examines mechanisms linking sleep, negative affect, stress biomarkers, and high/low stress contexts at the daily level, from the biopsychosocial perspective of stressor exposure and reactivity.

METHOD

173 caregivers (Mage = 61.97, sd = 10.66) were providing care at home and used adult day services (ADS) at least 2 days a week. Caregivers reported their bedtime, wake time, sleep quality, and nighttime problems of the person with dementia (PwD) daily for eight consecutive days, concurrently reporting non-care stressors, negative affect, and providing five salivary cortisol samples per day. We conducted multilevel analysis to examine whether caregiver sleep characteristics overnight (i.e., total time in bed, quality, and PwD sleep problems) were associated with their anxious and depressive symptoms on days where adult day services (ADS) were utilized versus non-ADS days (i.e., low- versus high-stress), and whether cortisol daily total output as area under the curve (AUCg) mediated the direct associations, at the within- and between-person levels.

RESULTS

On high-stress (i.e., non-ADS) days when caregivers had longer time in bed than usual the night before, they were less anxious on the following day; the direct association was statistically mediated through lower cortisol AUCg during the day.

DISCUSSION

Staying longer in bed than usual before an upcoming high-stress day may help dementia family caregivers better regulate cortisol stress reactivity and anxious symptoms.

Using Telehealth to Deliver Cognitive Behavioral Treatment of Insomnia to a Caregiver of a Person With Alzheimer's Disease

Cognitive behavioral therapy for Insomnia (CBT-I) is the gold standard treatment for insomnia. There is limited access to qualified providers to deliver CBT-I; moreover, there are patient populations who struggle with access to insomnia care due to limited time and resources. This includes caregivers for persons with Alzheimer's disease, for whom sleep disturbance is a common concern. Utilizing telehealth to deliver CBT-I may be particularly important for vulnerable populations such as caregivers of persons with dementia, as it can offer an accessible, safe, and cost-effective treatment option that can be tailored to meet the needs of a specific population. This case study illustrates the successful implementation of a four-session CBT-I protocol through telehealth with a caregiver of a person with Alzheimer's disease. Given the success of this case and the conditions for psychological care the recent pandemic has created, continued research into the efficacy of sleep-related interventions through telehealth is warranted.

The Role of Caregivers' Sleep Problems in the Association between Behavioral Symptoms of Dementia and Caregiving Depression and Anxiety

OBJECTIVES

Behavioral problems in people with dementia are a source of depression and anxiety for caregivers, who experience high levels of sleep problems. The present study aims to explore the role of sleep problems on the relationship between behavioral problems associated with dementias - considering its different dimensions - and family caregivers' depressive and anxious symptoms.

METHOD

264 family caregivers participated in the study. Through face-to-face interviews, sociodemographic and health variables, caregivers' depressive and anxious symptoms were measured, as well as their sleep problems. Data related to people with dementia symptoms and their level of independence in daily life activities were also collected. Data analysis consisted of simple mediational models using the PROCESS method for SPSS.

RESULTS

the test for the indirect effect of disruptive behaviors on depression through sleep problems was statistically significant, as it was for disruptive behaviors on anxiety through sleep problems. The effect of sleep problems in the association between depressive and memory problems in the person with dementia, and caregivers' depression and anxiety were not statistically significant.

CONCLUSIONS

Sleep problems are significantly and positively associated with care-recipients' disruptive behaviors, but not with depressive and memory problems. The indirect effect of disruptive behaviors on caregivers' mood through sleep problems suggests that disruptive behaviors seem to play an important role for understanding caregivers' sleep problems.

Lighting and Alzheimer's Disease and Related Dementias: Spotlight on Sleep and Depression

Alzheimer's disease and related dementias is the collective term for a progressive neurodegenerative disease for which there is presently no cure. This paper focuses on two symptoms of the disease, sleep disturbances and depression, and discusses how light can be used as a non-pharmacological intervention to mitigate their negative effects. Bright days and dark nights are needed for health and well-being, but the present components of the built environment, especially those places where older adults spend most of their days, are too dimly illuminated during the day and too bright at night. To be effective light needs to be correctly specified, implemented, and measured. Yet without the appropriate specification and measurement of the stimulus, researchers will not be able to successfully demonstrate positive results in the field, nor will lighting designers and specifiers have the confidence to implement lighting solutions for promoting better sleep and mood in this population.

Adapting a whole health model to home-based primary care: Bridging person-driven priorities with veteran and family-centered geriatric care

Through the integration of Whole Health for Life into the Department of Veterans Affairs (VA) health care system, the VA aims to transform health care delivery from a disease management approach to one that embraces person-centered care. The home-based primary care (HBPC) program is a care model that, within the VA, provides holistic primary care services to homebound veterans with multiple chronic medical conditions, mental health issues, and functional declines. These veterans may have limited access to VA programs delivered in a traditional outpatient format. This article describes adaptations to the whole health model of care that could improve its accessibility and applicability to HBPC veterans, caregivers, and the interdisciplinary teams that serve this population. These modifications are informed by whole-person geriatric and gerontological and family-systems theories and address population-based differences in the focus and approach to care. The focus on care is expanded to (a) reflect the importance of attending to caregiver needs and well-being and (b) shift from a preventative model to one that prioritizes resilience and maintenance. The approach to care emphasizes alternative modes of delivery, adaptations to interventions, and integration of geriatric-specific medical considerations into the self-care domains and more directly centers the collaboration between family, the VA, and community partners. This adapted model also addresses the unique needs of health care teams providing in-home services to medically complex veterans and offers suggestions for enhancing self-care and preventing burnout.

Intermittent Light Exposures in Humans: A Case for Dual Entrainment in the Treatment of Alzheimer's Disease

Circadian sleep disorders are common among American adults and can become especially acute among older adults, especially those living with Alzheimer's disease (AD) and mild cognitive impairment (MCI), leading to the exacerbation of symptoms and contributing to the development and advancement of the diseases. This review explores the connections between circadian sleep disorders, cognition, and neurodegenerative disease, offering insights on rapidly developing therapeutic interventions employing intermittent light stimuli for improving sleep and cognition in persons with AD and MCI. Light therapy has the potential to affect sleep and cognition via at least two pathways: (1) a regular and robust light-dark pattern reaching the retina that promotes circadian phase shifting, which can promote entrainment and (2) 40 Hz flickering light that promotes gamma-wave entrainment. While this is a new area of research, preliminary evidence shows the potential of dual circadian and gamma-wave entrainment as an important therapy not only for those with AD, but for others with cognitive impairment.

Sleep Quality in Caregivers of Older Patients with Schizophrenia Spectrum and Bipolar Disorders: A Case-Control Study

OBJECTIVES

Prior literature has documented the global burden of serious mental illnesses. The present study aimed to compare the sleep quality in caregivers of older patients with schizophrenia spectrum and bipolar disorders with control participants who did not serve as caregivers.

METHODS

We performed a case-controlled, cross-sectional study among family caregivers of older patients with psychotic disorders in Razi Hospital, Tunisia. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index Scale (PSQI).

RESULTS

Fifty caregivers of older patients (≥ 60 years) with schizophrenia spectrum and bipolar disorders, and 50 matched controls were enrolled. The three sub-dimensions of the PSQI, namely subjective sleep quality, sleep duration, and sleep efficiency, as well as overall PSQI scores, were worse for caregiver participants. Hierarchical multiple regression analyses predicting PSQI scores revealed that caregivers' age and marital status were the only significant predictors in the final model.

CONCLUSIONS

Older adults with severe mental disorders constitute a vulnerable population which generates a significant burden of care, and impacts their caregivers' subjective sleep quality.

CLINICAL IMPLICATIONS

Family interventions, including sleep interventions, should be considered as an integral component of treatment for serious mental illnesses. When promoting sleep quality, older and single caregivers should be targeted.

Long-Term, All-Day Exposure to Circadian-Effective Light Improves Sleep, Mood, and Behavior in Persons with Dementia

BACKGROUND

Persons with Alzheimer's disease and related dementias (ADRD) frequently experience sleep-wake (circadian) cycle disturbances that lead them to remain awake at night, causing stress and fatigue for families and caregivers. Light therapy shows promise as a nonpharmacological treatment for regulating sleep in this population.

OBJECTIVE

We investigated the long-term impact of a circadian-effective lighting intervention on sleep, mood, and behavior problems in persons with ADRD.

METHODS

This 25-week clinical trial administered an all-day lighting intervention to 47 patients with ADRD in 9 senior-care facilities, employing wrist-worn actigraphy measures and standardized measures of sleep quality, mood, and behavior.

RESULTS

The intervention significantly improved Pittsburgh Sleep Quality Index scores, from an estimated mean±SEM of 11.89±0.53 at baseline to 5.36±0.63 at the end of the intervention. Additional improvements were noted for sleep efficiency data from actigraph measurements. The intervention significantly reduced Cornell Scale for Depression in Dementia scores (mean±SEM of 11.36±0.74 at baseline and 4.18±0.88 at the end of the intervention) and Cohen-Mansfield Agitation Inventory scores (mean±SEM of 47.10±1.98 at baseline and 35.33±2.23 at the end of the intervention).

CONCLUSION

A regular circadian-effective daytime lighting intervention can improve sleep at night and reduce depression and agitation in patients with dementia living in controlled environments. More importantly, the positive effects of the tailored lighting intervention on these outcomes appear to be cumulative over time.

Sleep quality prediction in caregivers using physiological signals

Most caregivers of people with dementia (CPWD) experience a high degree of stress due to the demands of providing care, especially when addressing unpredictable behavioral and psychological symptoms of dementia. Such challenging responsibilities make caregivers susceptible to poor sleep quality with detrimental effects on their overall health. Hence, monitoring caregivers' sleep quality can provide important CPWD stress assessment. Most current sleep studies are based on polysomnography, which is expensive and potentially disrupts the caregiving routine. To address these issues, we propose a clinical decision support system to predict sleep quality based on trends of physiological signals in the deep sleep stage. This system utilizes four raw physiological signals using a wearable device (E4 wristband): heart rate variability, electrodermal activity, body movement, and skin temperature. To evaluate the performance of the proposed method, analyses were conducted on a two-week period of sleep monitored on eight CPWD. The best performance is achieved using the random forest classifier with an accuracy of 75% for sleep quality, and 73% for restfulness, respectively. We found that the most important features to detect these measures are sleep efficiency (ratio of amount of time asleep to the amount of time in bed) and skin temperature. The results from our sleep analysis system demonstrate the capability of using wearable sensors to measure sleep quality and restfulness in CPWD.

DREAMS-START (Dementia RElAted Manual for Sleep; STrAtegies for RelaTives) for people with dementia and sleep disturbances: a single-blind feasibility and acceptability randomized controlled trial

ABSTRACTBackground:40% of people with dementia have disturbed sleep but there are currently no known effective treatments. Studies of sleep hygiene and light therapy have not been powered to indicate feasibility and acceptability and have shown 40-50% retention. We tested the feasibility and acceptability of a six-session manualized evidence-based non-pharmacological therapy; Dementia RElAted Manual for Sleep; STrAtegies for RelaTives (DREAMS-START) for sleep disturbance in people with dementia.

METHODS

We conducted a parallel, two-armed, single-blind randomized trial and randomized 2:1 to intervention: Treatment as Usual. Eligible participants had dementia and sleep disturbances (scoring ≥4 on one Sleep Disorders Inventory item) and a family carer and were recruited from two London memory services and Join Dementia Research. Participants wore an actiwatch for two weeks pre-randomization. Trained, clinically supervised psychology graduates delivered DREAMS-START to carers randomized to intervention; covering Understanding sleep and dementia; Making a plan (incorporating actiwatch information, light exposure using a light box); Daytime activity and routine; Difficult night-time behaviors; Taking care of your own (carer's) sleep; and What works? Strategies for the future. Carers kept their manual, light box, and relaxation recordings post-intervention. Outcome assessment was masked to allocation. The co-primary outcomes were feasibility (≥50% eligible people consenting to the study) and acceptability (≥75% of intervention group attending ≥4 intervention sessions).

RESULTS

In total, 63out of 95 (66%; 95% CI: 56-76%) eligible referrals consented between 04/08/2016 and 24/03/2017; 62 (65%; 95% CI: 55-75%) were randomized, and 37 out of 42 (88%; 95% CI: 75-96%) adhered to the intervention.

CONCLUSIONS

DREAM-START for sleep disorders in dementia is feasible and acceptable.

Informal caregiving burden and perceived social support in an acute stroke care facility

Background

Providing informal caregiving in the acute in-patient and post-hospital discharge phases places enormous burden on the caregivers who often require some form of social support. However, it appears there are few published studies about informal caregiving in the acute in-patient phase of individuals with stroke particularly in poor-resource countries. This study was designed to evaluate the prevalence of caregiving burden and its association with patient and caregiver-related variables and also level of perceived social support in a sample of informal caregivers of stroke survivors at an acute stroke-care facility in Nigeria.

Methods

Ethical approval was sought and obtained. Fifty-six (21 males, 35 females) consecutively recruited informal caregivers of stroke survivors at the medical ward of a tertiary health facility in South-Southern Nigeria participated in this cross-sectional survey. Participants’ level of care-giving strain/burden and perceived social support were assessed using the Caregiver Strain Index and the Multidimensional Scale of Perceived Social Support respectively. Caregivers’ and stroke survivors’ socio-demographics were also obtained. Data was analysed using frequency count and percentages, independent t-test, analysis of variance (ANOVA) and partial correlation at α =0.05.

Results

The prevalence of care-giving burden among caregivers is 96.7% with a high level of strain while 17.9% perceived social support as low. No significant association was found between caregiver burden and any of the caregiver- or survivor-related socio-demographics aside primary level education. Only the family domain of the Multidimensional Scale of Perceived Social Support was significantly correlated with burden (r = − 0.295).

Conclusion

Informal care-giving burden was highly prevalent in this acute stroke caregiver sample and about one in every five of these caregivers rated social support low. This is a single center study. Healthcare managers and professionals in acute care facilities should device strategies to minimize caregiver burden and these may include family education and involvement.

"What Hath Night to Do with Sleep?": The Caregiving Context and Dementia Caregivers' Nighttime Awakenings

OBJECTIVES

Care provision for persons with dementia can be rewarding yet may disrupt caregiver's sleep health. Using the National Health & Aging Trends Study and the National Study of Caregiving, we examine care receiver and caregiver contextual factors, caregiver health and psychological wellbeing as predictors of caregivers' nighttime awakenings.

METHODS

The sample for this cross-sectional study included 451 caregivers for individuals with dementia surveyed by telephone.

RESULTS

Nighttime awakenings (1 item measure of waking and not being able to return to sleep) almost every night were reported by 16% of caregivers and 10% reported that helping the care receiver caused their sleep to be interrupted most nights. In a multinomial logistic regression, caregivers' greater nighttime awakenings were associated with caring for care recipients with higher fall risk, as well as caregiver characteristics of more chronic medical conditions and emotional difficulty of the care role.

CONCLUSIONS

Emotional caregiving difficulties were associated with nighttime awakenings even accounting for caregivers' health and care receivers' disability. Thus, interventions improving caregiver distress may improve sleep health.

CLINICAL IMPLICATIONS

Clinicians should screen caregivers for nighttime awakenings so that evidence-based interventions and treatments can be implemented to prevent persistent sleep disturbances.

The Paradoxical Impact of Companionship on the Mental Health of Older African American Men

Objectives

African Americans comprise 9% of the 46 million U.S. adults over age 65. Two thirds of older African American men (AAM) reside with companions. This study investigated the assumption that frequent contact with companions confers mainly health-related benefits for AAM.

Methods

Utilizing secondary data from the National Alzheimer's Coordinating Center, the relationship between older AAM's mental health and related conditions (depression, anxiety, and sleep disturbances), companion living arrangements, and frequency of contact with the participants for 3,423 older AAM and their 1,161 companions, was examined.

Results

The mean age of participants and companions was 74 years and 90% of AAM lived in a private residence. Logistic regression models indicated that an increased risk for anxiety was found when companions lived in (OR = 1.66), called daily (OR = 1.089), or visited daily (OR = 1.079). Finally, AAM had an increased likelihood of nonmedical sleep disturbances when companions lived in (OR = 1.67), called daily (1.105), or visited daily (1.078).

Discussion

The frequency of contact with companions may be consequential for select mental health outcomes and associated physiological conditions for older AAM; the timing of contact requires further investigation.

Sleep disturbances in caregivers of patients with advanced cancer: A systematic review

OBJECTIVE

Sleep disturbances are a common issue for those who provide informal care to someone with a life-limiting condition. The negative consequences of poor sleep are well documented. The purpose of the present study was to determine the sleep patterns of caregivers of patients with advanced cancer.

METHOD

An extensive systematic review of studies reporting empirical sleep data was undertaken in 2015 in accordance with the PRISMA Statement. A total of eight electronic databases were searched, with no date restrictions imposed. Additionally, a search of the bibliographies of the studies identified during the electronic search was conducted. Search terms included: "sleep," "insomnia," "sleep disturbance," "circadian rhythm," "caregiver," "carer," "advanced cancer," "palliative cancer," and MESH suggestions. The inclusion criteria required studies to be in English and to report primary qualitative and/or quantitative research that examined sleep in caregivers of patients with advanced cancer. Unpublished studies, conference papers, and dissertations were excluded.

RESULTS

Overall, 10 studies met the inclusion criteria and were included in the review. Two major findings emerged from the data synthesis. First, at least 72% of caregivers reported moderate to severe sleep disturbance as measured by the Pittsburgh Sleep Quality Index. Second, objective measurement of caregivers' sleep identified that some caregivers experienced up to a 44% reduction in their total sleep time compared to the recommended eight hours.

SIGNIFICANCE OF RESULTS

Reduction in total sleep time appears to be the biggest issue facing caregivers' sleep. Future studies need to explore the specific factors that cause these sleep disturbances and thus help to identify interventions to optimize sleep.

Effects of the behavior of elderly type 2 diabetic patients and their relatives as caregivers on diabetes follow-up parameters in Bolu, Turkey

AIM

In the present study, patients with type 2 diabetes mellitus and their relatives as caregivers during the treatment period, and the effects on treatment success were evaluated.

METHODS

A cross-sectional study of type 2 diabetes mellitus patients aged 65 years and older and their relatives as caregivers was carried out. The questionnaire given to the participants consisted of three sections: the first section included questions regarding sociodemographic characteristics; the second section included questions on patient treatment, habits of drug use, lifestyle changes such as dietary habits; and the third section included anthropometric measurements and laboratory evaluations. The questionnaire given to the patients' relatives as caregivers consisted of questions regarding their sociodemographic characteristics and information regarding the patient.

RESULTS

The present study consisted of 115 patients diagnosed with type 2 diabetes mellitus and their relatives as caregivers. The average duration of diabetes was 12.14 ± 6.74 years. Body mass index was 30.2 ± 4.2 kg/m(2) , average hemoglobin A1c level was 7.09 ± 0.64%, and 40.1% of the patients lived with their partners only. As the frequency of physical exercise increased, hemoglobin A1c levels decreased to <7.5% (P < 0.05).The patients whose caregivers were college-educated or equivalent had a significantly low body mass index (P < 0.05). Patients who lived with their partners showed a significant correlation with lower hemoglobin A1c levels (<7.5%; P = 0.002).

CONCLUSION

In order to improve diabetic conditions in the elderly and to overcome obstacles to disease management, maximizing the cooperative efforts between the patients and their caregivers is necessary.

Family caregivers' sleep disturbance and its associations with multilevel stressors when caring for patients with dementia

OBJECTIVE

We tested a stress process model of multilevel stressors on sleep disturbance for family caregivers (FCG) of persons with dementia (PWD).

METHODS

For this cross-sectional study, trained research assistants collected data from a purposive sample of 180 PWD-FCG dyads at two teaching hospitals, two local hospitals, and two community long-term care service programs in northern Taiwan. PWDs' neuropsychiatric symptoms were assessed using the Chinese Neuropsychiatric Inventory (CNPI), FCGs' distress by CNPI Caregiver Distress Scale, physical fatigue by Visual Analogue for Fatigue Scale, mental fatigue by Attentional Function Index, depressive symptoms by the Center for Epidemiological Studies Depression Scale - Short Form, and sleep disturbance by the General Sleep Disturbance Scale.

RESULTS

FCGs' most prevalent sleep disturbance problems were sleep quality problems (99.4%). Hierarchical regression models revealed that FCGs' sleep disturbance was predicted by their physical fatigue, their depressive symptoms, and the synergistic effect of physical fatigue and depressive symptoms in the final model, explaining 57.8% of the variance.

CONCLUSIONS

This study supports the model that development of caregivers' sleep problems may depend on their depression, fatigue, and the synergistic effects of these two variables. These findings suggest that clinicians should educate FCGs about self-care and offer strategies for dealing with a cluster of symptoms when maintaining sleep hygiene.

Sleep disturbances and predictive factors in caregivers of patients with mild cognitive impairment and dementia

Background and Purpose

We examined the characteristics of sleep disturbances and sleep patterns in the caregivers of patients with amnestic mild cognitive impairment (aMCI) and dementia.

Methods

We prospectively studied 132 patients (60 with aMCI and 72 with dementia) and their caregivers, and 52 noncaregiver controls. All caregivers and controls completed several sleep questionnaires, including the Pittsburgh Sleep Quality Index (PSQI). The patients were administered neuropsychological tests and the neuropsychiatric inventory to evaluate their behavioral and neuropsychiatric symptoms of dementia (BPSD).

Results

The PSQI global score was 6.25±3.88 (mean±SD) for the dementia caregivers and 5.47±3.53 for the aMCI caregivers. The Insomnia Severity Index (ISI) and short form of the Geriatric Depression Scale (GDS-S) predicted higher PSQI global scores in aMCI caregivers, and higher scores for the ISI, Epworth Sleepiness Scale (ESS), and GDS-S in dementia caregivers. BPSD, including not only agitation, depression, and appetite change in dementia patients, but also depression, apathy, and disinhibition in aMCI patients, was related to impaired sleep quality of caregivers, but nighttime behavior was not. Age and gender were not risk factors for disturbed sleep quality.

Conclusions

Dementia and aMCI caregivers exhibit impaired quality of sleep versus non-caregivers. ISI, GDS-S, and ESS scores are strong indicators of poor sleep in dementia caregivers. In addition, some BPSD and parts of the neuropsychological tests may be predictive factors of sleep disturbance in dementia caregivers.

Positive affect and sleep in spousal Alzheimer caregivers: a longitudinal study

This article examines the longitudinal relation between positive affect (PA) and sleep in 126 spousal Alzheimer's disease caregivers. Caregivers underwent 4 yearly assessments for the Positive and Negative Affect Schedule, the self-rated Pittsburgh Sleep Quality Index, and actigraphy to objectify nighttime total sleep time, wake after sleep onset, and percentage of sleep. Increased levels of PA and a greater positivity (i.e., positive-to-negative affect) ratio were significantly associated with better subjective sleep over the entire study period. Yearly increases in PA-even when controlling for negative affect (NA)-and in the positivity ratio were also associated with better subjective sleep. PA and actigraphy measures showed no significant relations. Increased PA is longitudinally associated with better sleep in dementia caregivers largely independent of NA.

Social support and mastery influence the association between stress and poor physical health in parents caring for children with developmental disabilities

To date, much of the research linking the stress of caring for children with developmental disabilities (e.g. Autism & Down syndrome) with parental health outcomes have tended to concentrate on mental health with less attention paid to the physical health consequences. Thus, this study sought to explore the psychosocial predictors of poor physical health in these caring parents. One hundred and sixty-seven parents (109 caregivers and 58 control parents) completed measures of stress, child problem behaviours, social support, mastery and physical health. Parents of children with developmental disabilities had poorer physical health compared to control parents. Stress and mastery, but not social support and problem behaviours, were significant predictors of poor physical health within caring parents for children with developmental disabilities. However, the association between mastery and physical health was mediated by perceived stress such that those parents who were higher on mastery reported less stress and better physical health; furthermore, the association between stress and physical health was moderated by social support; those parents high on social support and low in stress had better physical health. These results indicate that the paths between psychosocial factors and poor physical health in the caring parents are working synergistically rather than in isolation. They also underscore the importance of providing multi-component interventions that offer a variety of psychosocial resources to meet the precise needs of the parents.

Sleep in older adults: normative changes, sleep disorders, and treatment options

Approximately 5% of older adults meet criteria for clinically significant insomnia disorders and 20% for sleep apnea syndromes. It is important to distinguish age-appropriate changes in sleep from clinically significant insomnia, with the latter having associated daytime impairments. Non-pharmacologic therapies, such as cognitive-behavioral therapy for insomnia, can be highly effective with sustained benefit. Pharmacologic therapies are also available, but may be associated with psychomotor effects. A high index of suspicion is crucial for effective diagnosis of sleep apnea because symptoms commonly noted in younger patients, such as obesity or loud snoring, may not be present in older patients.

A typology of care-giving across neurodegenerative diseases presenting with dementia

The purpose of this study is to develop and extend our understanding of dementia care-giving by introducing a typology of informal care-giving across four different diseases. Care-giving factors were examined with respect to specific dementia presentation in mild cognitive impairment, Alzheimer's disease, dementia with Lewy bodies and Parkinson's disease-associated dementia. Informal care-giving literature in the four diseases was systematically searched to identify specific disease symptoms and resultant care-giving strains and outcomes. Key concepts were extracted and grouped thematically. The first classification, ‘role-shift’, reflects care-giving where cognitive deterioration results in changing roles, uncertainty and relational deprivation among married partners. The second classification, ‘consumed by care-giving’, refers to those caring for persons with dementia-motor decline that greatly increases worry and isolation. Finally, in the ‘service use’ classification, formal support is needed to help care-givers cope with daily responsibilities and behaviour changes. In each case, the dementia presentation uniquely impacts care-giver strains. A major conclusion is that the same support to all care-givers under the umbrella term ‘dementia’ is unwarranted; the development of targeted support is required.

Impaired Autonomic Nervous System Activity During Sleep in Family Caregivers of Ambulatory Dementia Patients in Japan

The number of dementia patients requiring care is rapidly increasing in Japan. Consequently, a large percentage of family members, including spouses and children of those with dementia, are assuming the role of primary caregiver. Many caregivers develop health problems including sleep disorders. Some report poor quality of sleep even when sleep duration is normal. In the present study, we used actigraphy and heart rate variability spectral analysis to assess autonomic nervous system activity and quality of sleep in family caregivers of people with ambulatory dementia. The 20 caregivers who participated in our study exhibited significantly higher levels of sympathetic nervous system activity during sleep than noncaregivers. This abnormal activity was most prominent during the first half of the sleep period and was not related to overall sleep duration. We propose that relaxation is inhibited during the first half of the sleep period in this caregiver population. This may be due to increased stress, as caregivers of people with ambulatory dementia may worry about their patients waking and wandering at night, potentially injuring themselves. Our findings indicate a need for increased support for caregivers of people with dementia, including the assessment and treatment of sleep disorders.

Approach to insomnia in patients with dementia

Insomnia occurs in one-fourth to one-third of patients with dementia, and can lead to patient and caretaker distress and early institutionalization. An array of effects from the disease, medication, behaviors, and mood issues may play a role in influencing sleep. This perplexing issue can be handled effectively with appropriate evaluation and understanding of basic sleep-wake physiology. For most patients, appropriate timing of cues, modifying behavior, and optimizing medications can improve the patient's and caregiver's quality of life. In this article, we review signs that may help the clinician recognize insomnia early and approach the issue in a logical manner.

Subtypes of sleep problems in patients with Alzheimer disease

OBJECTIVE

Sleep disturbances are common in patients with Alzheimer disease (AD) and can contribute to cognitive dysfunction and a negative impact on patients' and caregivers' quality of life. The purpose of this study was to evaluate whether subtypes of sleep disturbance could be identified in patients with AD and to assess the relation of these subtypes to patient characteristics and caregiver mood.

METHODS

As part of routine clinical assessment, primary caregivers of 344 patients with AD completed a questionnaire that included five items about the patients' sleep. Patients' cognitive and functional status and their mood were assessed as was caregivers' mood. Latent class analysis was used to define subgroups of patients based on their sleep patterns. After identification of groups of sleep disturbance, the relation of group membership to patient and caregiver characteristics was also evaluated.

RESULTS

Analyses revealed groups with moderate and severe sleep problems as well as a group without problems. Patients with more severe sleep disturbance were older, less well educated, and had poorer cognitive and functional status. Caregiver and patient depression was related to membership in the severe group, suggesting that both may contribute to caregivers' ratings of more severe sleep disturbance, whereas only patient depression was related to membership in the moderate group.

CONCLUSION

Sleep problems in patients with AD are related to poorer cognitive and functional status and patient and caregiver depression. Caregiver depression was most closely related to more severe patient sleep disturbance.

Association between hospice care and psychological outcomes in Alzheimer's spousal caregivers

CONTEXT

Dementia care giving can lead to increased stress, physical and psychosocial morbidity, and mortality. Anecdotal evidence suggests that hospice care provided to people with dementia and their caregivers may buffer caregivers from some of the adverse outcomes associated with family caregiving in Alzheimer's Disease (AD).

OBJECTIVES

This pilot study examined psychological and physical outcomes among 32 spousal caregivers of patients with AD. It was hypothesized that caregivers who utilized hospice services would demonstrate better outcomes after the death of their spouse than caregivers who did not utilize hospice.

METHODS

The charts of all spousal caregivers enrolled in a larger longitudinal study from 2001 to 2006 (N=120) were reviewed, and participants whose spouse had died were identified. Of these, those who received hospice care (n=10) were compared to those who did not (n=22) for various physiological and psychological measures of stress, both before and after the death of the care recipient. An Analysis of Covariance (ANCOVA), with postdeath scores as the dependent variable and pre-death scores as covariates, was used for all variables.

RESULTS

Significant group differences were found in postdeath depressive symptoms (HAM-D; F(1,29)=6.10, p<0.05) and anxiety symptoms (HAM-A; F(1,29)=5.71, p<0.05). Most psychological outcome variables demonstrated moderate effect sizes with a Cohen's d of>0.5 between groups.

CONCLUSIONS

These data suggest that hospice enrollment may ameliorate the detrimental psychological effects in caregivers who have lost a spouse with Alzheimer's Disease. Based on these pilot data, further prospective investigation is warranted.

A yoga and compassion meditation program reduces stress in familial caregivers of Alzheimer's disease patients

Familial caregivers of patients with Alzheimer's disease exhibit reduced quality of life and increased stress levels. The aim of this study was to investigate the effects of an 8-week yoga and compassion meditation program on the perceived stress, anxiety, depression, and salivary cortisol levels in familial caregivers. A total of 46 volunteers were randomly assigned to participate in a stress-reduction program for a 2-month period (yoga and compassion meditation program—YCMP group) (n = 25) or an untreated group for the same period of time (control group) (n = 21). The levels of stress, anxiety, depression, and morning salivary cortisol of the participants were measured before and after intervention. The groups were initially homogeneous; however, after intervention, the groups diverged significantly. The YCMP group exhibited a reduction of the stress (P < 0.05), anxiety (P < 0.000001), and depression (P < 0.00001) levels, as well as a reduction in the concentration of salivary cortisol (P < 0.05). Our study suggests that an 8-week yoga and compassion meditation program may offer an effective intervention for reducing perceived stress, anxiety, depression, and salivary cortisol in familial caregivers.

Use of psychotropic medications by caregivers of elderly patients with dementia: is this a sign of caregiver burden?

This study evaluated the consumption of psychotropic medications by caregivers of elderly patients with or without dementia. This was a cross-sectional study conducted at all geriatric units in Brasília, Brazil, during a two-month period. Structured interviews were performed with 311 caregivers of people with or without dementia and they completed questionnaires. Among the caregivers, 196 (63%) were caregivers of patients with dementia and 115 (37%) were caregivers of patients without dementia. Forty-four caregivers (14.1%) were taking psychotropic drugs (benzodiazepines or antidepressants), and this usage was more frequent among caregivers of patients with dementia (p<0.01). Twenty-two caregivers of patients with dementia (11.4%) had used sleeping pills after beginning care, compared with only five (4.3%) caregivers of patients without dementia (p<0.01). In conclusion, this study found that caregivers of patients with dementia took psychotropic drugs (benzodiazepines and antidepressants) more frequently than the ones of patients without dementia.

The effects of meditation on perceived stress and related indices of psychological status and sympathetic activation in persons with Alzheimer's disease and their caregivers: a pilot study

Objective. To investigate the effects of an 8-week meditation program on perceived stress, sleep, mood, and related outcomes in adults with cognitive impairment and their caregivers. Methods. Community-dwelling adults with a diagnosis of mild cognitive impairment or early-stage Alzheimer's disease, together with their live-in caregivers, were enrolled in the study. After a brief training, participants were asked to meditate for 11 minutes, twice daily for 8 weeks. Major outcomes included measures of perceived stress (Perceived Stress Scale), sleep (General Sleep Disturbance Scale), mood (Profile of Mood States), memory functioning (Memory Functioning Questionnaire), and blood pressure. Participants were assessed pre- and post-intervention. Results. Ten participants (5 of 6 dyads) completed the study. Treatment effects did not vary by participant status; analyses were thus pooled across participants. Adherence was good (meditation sessions completed/week: X = 11.4 ± 1.1). Participants demonstrated improvement in all major outcomes, including perceived stress (P < 0.001), mood (overall, P = 0.07; depression, P = 0.01), sleep (P < 0.04), retrospective memory function (P = 0.04), and blood pressure (systolic, P = 0.004; diastolic, P = 0.065). Conclusions. Findings of this exploratory trial suggest that an 8-week meditation program may offer an acceptable and effective intervention for reducing perceived stress and improving certain domains of sleep, mood, and memory in adults with cognitive impairment and their caregivers.

Sleep in spousal Alzheimer caregivers: a longitudinal study with a focus on the effects of major patient transitions on sleep

STUDY OBJECTIVES

Findings on sleep disturbances in family dementia caregivers are conflicting. We studied the longitudinal effects of dementia caregiving and major transitions in the caregiving situation on caregivers' sleep and the effect of moderating variables.

DESIGN AND SETTING

Community-based longitudinal study with assessments about once a year for up to three years.

PARTICIPANTS

A sample of 109 elderly spousal Alzheimer caregivers and 48 non-caregiving age- and gender-matched controls.

MEASUREMENTS AND RESULTS

Random regression models with fixed and time-variant effects for covariates known to affect sleep were used to evaluate changes in the Pittsburgh Sleep Quality Index (PSQI) and in four actigraphy measures over time in relation to caregiving status and transitions (i.e., nursing home placement or death of the Alzheimer disease spouse). Multivariate-adjusted sleep characteristics did not significantly differ between caregivers and non-caregivers over time. Spousal death increased caregivers' nighttime wake after sleep onset (WASO) by 23 min (P = 0.002) and daytime total sleep time (TST) by 29 min (P = 0.003), while nighttime sleep percent decreased by 3.2% (P = 0.009) and nighttime TST did not change. Placement of the spouse had no significant effect on caregivers' sleep. Older age, male gender, role overload, depressive symptoms, and proinflammatory cytokines variously emerged as significant moderators of the relationships between caregiving and transitions with poor subjective and objective sleep.

CONCLUSIONS

Alzheimer caregivers and non-caregiving controls had similar trajectories of sleep. However, there may be subgroups of caregivers who are vulnerable to develop sleep disturbances, including those whose spouses have died.

Treating sleep problems in dementia caregivers based on parent-child interventions

BACKGROUND

Interventions developed for improving sleep in parents of young children or in developmentally delayed children might also prove effective for persons with dementia and their caregivers.

METHODS

We selectively reviewed the literature for interventions effective in improving sleep in parents of young children or in developmentally delayed children.

RESULTS

Graduated extinction and adult fading have been minimally explored in dementia populations. They are fairly brief and could be administered during primary care or dementia clinic visits. Combination strategies such as extinction and sleep-enhancing medication are very effective and may be applicable for persons with dementia and their caregivers. Physical capabilities and degree of cognitive decline of patients with dementia must be considered, and medical staff and caregivers should adjust behavioral strategies to maximize the use of patients' intact cognitive abilities.

CONCLUSIONS

Interventions for divergent populations prone to similar problems as those of patients with dementia might be effective and advance existing research.

Alzheimer's care at home: a focus on caregivers strain

The aging population is increasing worldwide. According to Italian authors, Italy is one of the leading and increasing aging populations in the world. Placing more numbers on the elderly increases the number of people who will live with dementia in the future and in our case of study, in an increase of people with Alzheimer's disease. Researchers have demonstrated that Alzheimer's disease comes with aging and it eventually affects the person's cognitive, emotional, and physical well being. Those who become diagnosed with Alzheimer's will eventually need assistance in their daily living, especially when it begins to progress to a higher stage. Daily assistance can come from staff at a hospital or from family members at home, but whether it is the patient's spouse or offspring, the person caring for the patient forms a burden of responsibility on themselves over time. The objective of this paper is to discuss and compare the effects of the burden placed on the Alzheimer's caregiver: sleep, anxiety and depression, stress, and use or nonuse of support services. The focus of this literature review is to submit what on the research of caregiver strain at home.

Assessing sleep architecture in dementia caregivers at home using an ambulatory polysomnographic system

Findings from previous research assessing sleep quality in caregivers are inconsistent due to differences in sleep assessment methods. This study evaluated sleep in dementia caregivers using a comprehensive sleep assessment utilizing an ambulatory polysomnography (PSG) device. A total of 20 caregivers and 20 noncaregivers rated their perceived sleep quality, stress, and depressive symptoms; provided samples of cortisol and inflammatory biomarkers; and completed an objective sleep assessment using a portable PSG device. Caregivers reported greater perceived stress than noncaregivers. Next, the groups had different sleep architecture: caregivers spent less proportion of their sleep in restorative sleep stages compared to noncaregivers. Further, levels of C-reactive protein and awakening salivary cortisol were greater in caregivers than in noncaregivers, and these measures were related to sleep quality. Our findings indicate that sleep disruption is a significant concomitant of caregiving and may affect caregiver's health. Sleep quality of caregivers might be a useful target for a clinical intervention.
