Sleep Disturbance in Bereavement

"It Started After Trauma": The Effects of Traumatic Grief on Sleep Paralysis

Adverse life events are associated with the often-terrifying REM sleep parasomnia of sleep paralysis (SP), but the impact of bereavement on SP has not been specifically examined. This exploratory, mixed-methods study (N = 168) includes qualitative data from 55 participants who described factors they believed led to their SP. Of these, almost half with a traumatic loss listed death-related precipitants. In unadjusted (bivariate) negative binomial regression models, traumatic death, time since death, religiosity, and age estimated increased SP frequency in the prior month, prior year, or both. In multivariable models, traumatic death, time since death, and age estimated increased frequency in the prior month, prior year, or both. Unexpectedly, in all models, as compared to death ≥9 years earlier, prior month SP was greater with death 1-6 years earlier, but not <1 year earlier. Discussion includes the possible role of social constraints in traumatic grief trajectories and care provider recommendations.

Poor Sleep is Common in Treatment-Resistant Late-life Depression and Associated With Poorer Antidepressant Response: Findings From the OPTIMUM Clinical Trial

BACKGROUND

Adults with treatment-resistant late-life depression (TRLLD) have high rates of sleep problems; however, little is known about the occurrence and change in sleep during pharmacotherapy of TRLLD. This analysis examined: (1) the occurrence of insufficient sleep among adults with TRLLD; (2) how sleep changed during pharmacotherapy; and (3) whether treatment outcomes differed among participants with persistent insufficient sleep, worsened sleep, improved sleep, or persistent sufficient sleep.

METHODS

Secondary analysis of data from 634 participants age 60+ years in the OPTIMUM clinical trial for TRLLD. Sleep was assessed using the sleep item from the Montgomery-Asberg Depression Rating Scale at the beginning (week-0) and end (week-10) of treatment. The analyses examined whether treatment outcomes differed among participants with persistent insufficient sleep, worsened sleep, improved sleep, or persistent sufficient sleep during depression treatment.

RESULTS

About half (51%, n = 323) of participants reported insufficient sleep at baseline. Both persistent insufficient sleep (25%, n = 158) and worsened sleep (10%, n = 62) during treatment were associated with antidepressant nonresponse. Participants who maintained sufficient sleep (26%, n = 164) or who improved their sleep (n = 25%, n = 158) were three times more likely to experience a depression response than those with persistent insufficient sleep or worsened sleep.

CONCLUSION

Insufficient sleep is common in TRLLD and it is associated with poorer treatment response to antidepressants.

Trajectories of insomnia following bereavement

BACKGROUND

Insomnia symptoms are common following bereavement and may exacerbate severe and protracted grief reactions, such as prolonged grief disorder (PGD). However, typical trajectories of insomnia symptoms and risk factors for having a more chronic insomnia trajectory following bereavement are yet unknown.

METHOD

In the current investigation, 220 recently bereaved (≤6 months post-loss) participants, completed questionnaires assessing sociodemographic and loss-related characteristics, rumination, experiential avoidance and symptoms of (prolonged) grief and depression, on three time-points (6 months apart). We applied growth mixture models to investigate the typical trajectories of insomnia symptoms following bereavement.

RESULTS

Three insomnia trajectory classes emerged, characterized by a resilient (47 %), recovering (43 %), and a chronic trajectory (10 %). Baseline depression symptoms best predicted the type of insomnia trajectory. At one-year follow-up, 9 %, 27 %, and 60 % of participants met the criteria for probable PGD within the resilient, recovering and chronic trajectory, respectively. A parallel process model showed that temporal changes in insomnia symptoms were strongly related to changes in prolonged grief symptoms.

CONCLUSION

The results suggest, that targeting insomnia symptoms in the treatment of PGD, particularly with comorbid depression, may be a viable option.

Adverse events in older adults and the risk of dementia and cognitive decline

Background

Increasing evidence suggests that stress could be a risk factor for dementia but this might vary by gender. This study investigated whether adverse life events were associated with cognitive decline and dementia in later-life, separately in men and women.

Methods

Participants were 12,789 community-dwelling Australians aged ≥ 70 years. Ten common adverse events in later-life were self-reported. Cognitive decline was defined as a 1.5 SD decline from participants' baseline score in tests of global cognition, psychomotor speed, episodic memory, and executive functioning, which were assessed regularly over a maximum of 10.3 years. Dementia was diagnosed according to DSM-IV criteria.

Results

An increased risk of dementia was observed in participants who experienced the death of a spouse/partner (HR: 1.72, 95% CI: 1.17 - 2.52) and for individuals who experienced major financial problems (HR: 1.53, 95% CI: 1.05 - 2.23). The latter also increased the risk of cognitive decline in men specifically (HR: 1.43, 95% CI: 1.10 - 1.86). In contrast, some events for women were associated with a reduced risk of dementia (e.g. close family or friends lost their job/retired (HR: 0.62, 95% CI: 0.40-0.95)).

Limitations

Events including major money problems may result from prodromal dementia symptoms, thus reverse causation needs to be considered.

Conclusions

Adverse life events may influence dementia risk in older adults, but associations vary depending on the nature of the event, and across genders. These findings support the need for early interventions in older people who have experienced adversities, particularly for the death of a loved one.

A digital health intervention to stabilize the 24-hour rhythm of sleep, meals, and physical activity for reducing depression among older bereaved spouses: Protocol for a randomized controlled trial

BACKGROUND

Despite the high prevalence of depression and disruption to 24-h sleep-wake routines following the death of a spouse in late-life, no bereavement interventions have been developed to re-entrain a regular sleep-wake routine among older widow(er)s. We describe the rationale and methodology of the NIH-funded WELL Study (Widowed Elders' Lifestyle after Loss), a randomized controlled trial (RCT) comparing the efficacy of a digital health intervention (DHI) to enhanced usual care (EUC) arm for reducing depression symptoms in older spousally-bereaved adults.

METHODS

We will randomize approximately 200 recently bereaved (<12 months) adults aged 60+ years to one of two 12-week interventions: digital monitoring of the timing and regularity of sleep, meals, and physical activity plus weekly motivational health coaching; or enhanced usual care consisting of weekly telephone calls and similar assessment schedules. Participants will complete self-report and clinical assessments at baseline, post-intervention, and 3-, 6-, and 12-months post-intervention, and objective actigraphic assessments of their 24-h rest-activity rhythm (RAR) at baseline and 1-, 2-, and 3-months during the intervention. The primary outcome is change in depression symptoms burden (using the Hamilton Rating Scale for Depression) from pre- to post-intervention and over 12 months of follow-up.

DISCUSSION

WELL Study findings will inform the development of widely generalizable and scalable technology-based interventions to support bereaved spouses in community-based settings. Clinical http://Trials.gov Identifier: NCT04016896.

Cross-Lagged Analyses of Prolonged Grief and Depression Symptoms with Insomnia Symptoms

Prolonged grief disorder, characterized by severe, persistent and disabling grief, has recently been added to the DSM-5-TR and ICD-11. Treatment for prolonged grief symptoms shows limited effectiveness. It has been suggested that prolonged grief symptoms exacerbate insomnia symptoms, whereas insomnia symptoms, in turn, may fuel prolonged grief symptoms. To help clarify if treating sleep disturbances may be a viable treatment option for prolonged grief disorder, we examined the proposed reciprocal relationship between symptoms of prolonged grief and insomnia. On three time points across 6-month intervals, 343 bereaved adults (88% female) completed questionnaires to assess prolonged grief, depression, and insomnia symptoms. We applied random intercept cross-lagged panel models (RICLPMs) to assess reciprocal within-person effects between prolonged grief and insomnia symptoms and, as a secondary aim, between depression and insomnia symptoms. Changes in insomnia symptoms predicted changes in prolonged grief symptoms but not vice versa. Additionally, changes in depression and insomnia symptoms showed a reciprocal relationship. Our results suggest that targeting insomnia symptoms after bereavement is a viable option for improving current treatments for prolonged grief disorder.

Childhood maltreatment, emotion regulation strategies and depressive symptoms during spousal bereavement

BACKGROUND

Childhood maltreatment increases the risk of depression, especially after experiencing a stressful life event, such as bereavement. Employing emotion regulation strategies can mitigate the impact childhood maltreatment has on depression later in life following the loss of a spouse.

OBJECTIVE

We evaluated how cognitive reappraisal and expressive suppression moderated the impact of childhood maltreatment and depressive symptoms following spousal bereavement.

PARTICIPANTS AND SETTING

We examined 130 bereaved individuals 3 months after the death of a spouse, 4 months after the death of a spouse, and 6 months after the death of a spouse.

METHODS

We utilized a mixed model approach to test the interaction between childhood maltreatment and cognitive reappraisal and between childhood maltreatment and expressive suppression to predict depressive symptoms across 3 time points.

RESULTS

Cognitive reappraisal moderated the relationship between childhood maltreatment and depressive symptoms (b = - 0.17,p = .003); expressive suppression did not (b = 0.06,p = .452). Participants who used less cognitive reappraisal had a positive relationship between childhood maltreatment and depressive symptoms (b = 3.27,p < .001);participants who used more cognitive reappraisal did not (b = 1.09,p = .065).

CONCLUSIONS

Childhood maltreatment interacted with cognitive reappraisal, but not expressive suppression, to predict depressive symptoms following spousal bereavement. This study reveals how emotion regulation strategies can be utilized as a tool to buffer the impact of childhood maltreatment on mental health following a stressor later in life, which can serve as a target for future interventions for individuals experiencing a stressful life event.

Prevalence and Factors Associated with Insomnia Among a Representative Sample of the Lebanese Population: Results of a Cross-Sectional Study

The objectives of the study were to identify the prevalence of insomnia among a representative sample of the Lebanese population and to assess potential factors associated with insomnia among this group. A cross-sectional study was done in the Lebanese population from August 2017 to April 2018 enrolling 789 participants using a proportionate random sample from all five Lebanese governorates. Participants filled a self-administered Arabic questionnaire. The Athens Insomnia Scale was used to diagnose insomnia. The Hamilton Depression Rating Scale and the Generalized Anxiety Disorder Scale were used to measure depression and anxiety, respectively. The prevalence of insomnia was 47.1% in the population sampled. The mean age of the participants was 37 years (64% females). Death in the family [adjusted odds ratio (aORa) = 1.59], drinking caffeine before sleep more than 2 days per week compared to none (aORa = 1.57), increased stress (aORa = 1.03), increased depression (aORa = 1.14), and anxiety scores (aORa = 1.07) were associated with higher odds of insomnia. The prevalence of insomnia was very high in the Lebanese population, and it was mainly associated with modifiable, treatable risk factors. Improved knowledge and adequate screening for insomnia are needed to promote better sleep quality.

Feasibility and preliminary efficacy of guided internet-delivered cognitive behavioral therapy for insomnia after the loss of a child to cancer: Randomized controlled trial

Bereaved individuals often experience sleep problems. The aim of this study was to evaluate feasibility and preliminary effects of internet-delivered cognitive behavioral therapy for insomnia (iCBT-i) in bereaved parents. Parents were randomized to iCBT-i (n = 10) or an active control group (n = 11). Primary outcome (insomnia) and secondary outcomes (prolonged grief, depression, posttraumatic stress, and grief rumination) were assessed pre- and post-treatment, with 9- and 18-month follow-ups. Feasibility was assessed post-treatment and one month later. Most parents reported positive effects of the treatment. The intervention group improved significantly from pre- to post-treatment and had a significantly larger reduction of insomnia when analyzed over all four time-points (Wald χ² = 30.0, p < 0.001), although the effect at post-treatment was very small (d = 0.1) for insomnia. Thus, iCBT-i was feasible and was related to reduced insomnia and psychological distress in bereaved parents, both short- and long-term, but the results regarding the treatment effect are preliminary due to the small sample size.

Sleep and social relationships in healthy populations: A systematic review

Over the past decade, research linking sleep and social relationships has burgeoned. Researchers across the globe are trying to understand whether the quality and quantity of our social relationships matter for sleep, and vice versa. We conducted a systematic review of the literature, identifying over 200 relevant articles examining sleep and social relationships in healthy populations. Here, we summarize our findings by reviewing 1) links between sleep and broad social ties across the lifespan, and 2) links between sleep and specific social relationships identified in the literature search, including romantic relationships, family relationships, and work relationships. Taken together, the literature provides evidence that the quality and presence of social relationships, especially our closest relationships, play a role in how we sleep. Likewise, sleep appears to influence our social bonds. However, the majority of work is correlational, limiting conclusions about the directionality of these effects. We conclude by synthesizing the findings, considering the limitations of the present literature, and identifying key future directions for this emerging area of research.

Poor Sleep Quality and Its Consequences on Mental Health During the COVID-19 Lockdown in Italy

Background

Coronavirus disease 2019 (COVID-19) seriously affected the whole of Italy. The extreme virulence and the speed of propagation resulted in restrictions and home confinement. This change was immediately perceived by people who found themselves exposed to feelings of uncertainty, fear, anger, stress, and a drastic change in the diurnal but above all nocturnal lifestyle. For these reasons, we aimed to study the quality of sleep and its connection to distress levels and to evaluate how lifestyle changed in the Italian population during the lockdown.

Methods

By means of an Internet survey we recruited 6,519 adults during the whole of the COVID-19 lockdown (from March 10–1st phase to May 4–2nd phase). We investigated the sociodemographic and COVID-19-related information and assessed sleep quality using the Medical Outcomes Study–sleep scale (MOS-SS) and mental health with the short form of Depression, Anxiety, and Stress Scales–21 Items (DASS-21). Multiple logistic regression model was used to evaluate the multivariate association between the dependent variable (good sleeper vs. poor sleeper) and all the variables that were significant in the univariate analysis.

Results

A total of 3,562 (55.32%) participants reported poor sleep quality according to the MOS-Sleep Index II score. The multiple binary logistic regression results of poor sleepers revealed several risk factors during the outbreak restrictions: female gender, living in Central Italy, having someone close who died because of COVID-19, markedly changed sleep–wake rhythms characterized by earlier or postponed habitual bedtime, earlier habitual awakening time and reduced number of afternoon naps, and extremely severe levels of stress, anxiety, and depression.

Conclusion

This is the first study designed to understand sleep quality and sleep habits during the whole of the lockdown period in the Italian population that provides more than 6,000 participants in a survey developed specifically for the health emergency related to COVID-19. Our study found that more than half of the Italian population had impaired sleep quality and sleep habits due to elevated psychological distress during the COVID-19 lockdown containment measures. A multidisciplinary action should be undertaken in order to plan appropriate responses to the current crisis caused by the lockdown for the COVID-19 outbreak.

Digital Monitoring of Sleep, Meals, and Physical Activity for Reducing Depression in Older Spousally-Bereaved Adults: A Pilot Randomized Controlled Trial

OBJECTIVES

To evaluate the feasibility and acceptability of a behavioral intervention and explore its impact on depression symptom burden among older spousally-bereaved adults.

METHODS

Participants were age ≥60 years, bereaved ≤8 months, and at high risk for depression. Participants were randomized to 12 weeks of digital monitoring of sleep, meals, and physical activity; digital monitoring plus health coaching; or enhanced usual care and followed for 9 months for new-episode depression.

RESULTS

We enrolled 57 participants, 85% of eligible adults and 38% of all adults screened. We observed high levels of adherence in both digital monitoring (90%) and health coaching (92%); 88% of participants were retained. In linear mixed-effects models, depression symptoms significantly decreased, but the interaction between time and intervention was not significant.

CONCLUSION

A behavioral intervention that uses both digital monitoring and motivational health coaching is feasible and acceptable to older bereaved adults.

Sleep disturbances in bereavement: A systematic review

Severe, persistent and disabling grief occurs among a sizable minority experiencing bereavement, with diagnostic manuals newly including complicated grief (CG) disorders. Sleep disturbances/disorders have been established as worsening affective and stress-related conditions. However, the role of sleep difficulties in bereavement and CG has not received similar scientific attention. We therefore conducted a systematic review with narrative syntheses on this topic to clarify the role of sleep in bereavement (PROSPERO: CRD42018093145). We searched PubMed, Web of Science and PsychInfo for peer-reviewed English-language articles including (at least one) bereaved sample and sleep disturbance measure. We identified 85 articles on 12.294 participants. We answered seven pre-defined research questions demonstrating: high prevalence of sleep disturbances in bereavement; positive associations of grief intensity with sleep difficulties; preliminary indications of risk factors of post-loss sleep disturbance; higher prevalence of sleep disturbances in CG, enhanced by psychiatric comorbidity (i.e., depression); and initial evidence of causal relationships between (complicated) grief and sleep. Grief therapy partly improves sleep difficulties, yet no intervention studies have specifically targeted sleep problems in bereaved persons. Causal relationships between sleep and grief require further examination in intensive longitudinal investigations, including randomized trials, thereby clarifying whether treating sleep problems enhances CG treatment effects.

Healthcare services and medication use among widowed partners of patients deceased due to cancer - results from the Survey of Health, Ageing and Retirement in Europe (SHARE)

OBJECTIVE

This study aimed to quantify the effect of a cancer death on healthcare and medication use among widowed individuals (Widowed-Cancer), by comparing this population with partnered individuals and with widowed individuals whose partners were deceased due to cardiovascular diseases (Widowed-CVD).

METHODS

Data were retrieved from the Sixth Wave of the Survey of Health, Ageing and Retirement in Europe - SHARE, conducted in 2015, in 18 countries. Widowed-Cancer were matched by country, sex, age and educational level with currently partnered individuals (1:2; n = 901 and n = 1802, respectively) and with Widowed-CVD (1:1; n = 606 and n = 606, respectively). Adjusted odds ratios (OR) and 95% confidence intervals (95%CI) were computed using logistic regression.

RESULTS

The use of drugs for sleep problems (OR = 1.42, 95%CI:1.12-1.80) and anxiety or depression (OR = 1.56, 95%CI:1.20-2.03) was more common among Widowed-Cancer than in partnered individuals; a tendency towards higher odds of being hospitalised in the previous year was also observed in Widowed-Cancer (OR = 1.20, 95%CI:0.98-1.47). Among participants whose partners were deceased in 2015, Widowed-Cancer were more likely than Widowed-CVD to report ≥10 contacts with medical doctors or nurses in the previous year (OR = 3.32, 95%CI:1.20-9.24; P for interaction = .042) and a higher use of drugs for sleep problems (OR = 14.43, 95%CI:1.74-119.84; P for interaction = .027).

CONCLUSION

Widowed individuals whose partners were deceased due to cancer had a higher use of healthcare, which highlights the importance of improving the quality of end-of-life care, even during widowhood.

Increased risk for hip fracture after death of a spouse-further support for bereavement frailty?

Death of a spouse is associated with poorer physical and mental health. We followed all married individuals, born from 1902 to 1942, during the period from 1987 to 2002, and found that widows and widowers had higher risk for hip fracture, compared with still married women and men.

INTRODUCTION

Spousal bereavement can lead to poorer physical and mental health. We aimed to determine whether married women and men had an elevated risk of hip fracture after death of a spouse.

METHODS

In a retrospective cohort study, we followed all Swedish married individuals aged 60 to 100 years (n = 1,783,035), from 1987 to 2002. Data are presented as mean with 95% confidence interval (CI).

RESULTS

During the follow-up period, 21,305 hip fractures among widows and 6538 hip fractures among widowers were noted. The hazard ratio (HR) for hip fracture in widows compared with married women was 1.34 (95% CI 1.31 to 1.37) and for widowers compared with married men 1.32 (95% CI 1.29 to 1.35). The HR for hip fracture in the first 6 months after death of a spouse was in widows compared with married women 1.62 (95% CI 1.53 to 1.71) and in widowers compared with married men 1.84 (95% CI 1.68 to 2.03). The elevated risk was especially prominent in young widowers in the age range 60-69 years. During the first 6 months they showed a HR of 2.76 (95% CI 1.66 to 4.58) for a hip fractvure compared with age matched married men. Widows aged 60-69 years showed a HR of 1.59 (95% CI 1.26 to 1.99) compared with age matched married women.

CONCLUSION

Our observation of a higher hip fracture risk in both genders in connection with the death of a spouse indicates a possible effect of bereavement on frailty.

Differential psychological reactions to grief: The role of childhood adversity for depression symptoms among bereaved and non-bereaved adults

Childhood maltreatment dysregulates an individual's physiological response to stress, increasing reactivity to stressors across the lifespan. Given the prevalence and impact of bereavement, we examined whether the association between childhood maltreatment and depression was exacerbated by spousal bereavement. We identified an interaction between childhood maltreatment and bereavement using linear regression analysis (B = 0.79, p < .001). A simple slopes test indicated a positive association between childhood maltreatment and depressive symptoms among those who were bereaved (B = 0.86, p < .001), but such association did not emerge among those who were not bereaved (B = 0.06, p = .60).

Rumination in bereaved parents: Psychometric evaluation of the Swedish version of the Utrecht Grief Rumination Scale (UGRS)

Background

Bereaved parents may be at higher risk to develop persistent, severe and disabling grief, termed prolonged grief. Grief rumination, repetitive thinking about the causes and consequences of the loss, is a malleable cognitive process that maintains prolonged grief. Grief rumination can be measured with the Utrecht Grief Rumination Scale (UGRS). The present study aimed to examine the psychometric properties of the new Swedish version of the UGRS in a sample of bereaved parents.

Methods

A Swedish nationwide postal survey including measures of demographic and loss-related variables, grief rumination (UGRS), and symptoms of prolonged grief, posttraumatic stress, anxiety, depression, and insomnia, was completed by 226 parents (133 mothers and 93 fathers) who lost a child to cancer in the past five years. Psychometric properties of the UGRS were examined through confirmatory factor analyses (CFA), reliability analyses, and assessment of UGRS score associations with symptoms of prolonged grief, posttraumatic stress, depression, anxiety, and insomnia.

Results

The internal consistency of the Swedish UGRS was good. The CFA yielded an acceptable fit for a two-factor hierarchical model with five sub-factors. Grief rumination was positively associated with all psychopathology symptom measures. Higher scores on UGRS were found in parents with possible prolonged grief disorder compared to those without (d = 1.47). Moreover, the Swedish UGRS was associated with prolonged grief symptoms over and above loss-related and demographic variables and other psychopathology symptoms.

Conclusions

The Swedish UGRS demonstrated good psychometric properties, which supports its use as a measure to assess grief rumination in Swedish bereaved parents in research and practice.

The Longitudinal and Cross-Sectional Associations of Grief and Complicated Grief With Sleep Quality in Older Adults

OBJECTIVE/BACKGROUND

About 15% of grievers experience complicated grief. We determined cross-sectional and longitudinal relations of grief and complicated grief with sleep duration and quality in the general population of elderly adults.

PARTICIPANTS

We included 5,421 men and women from the prospective population-based Rotterdam Study.

METHODS

The Inventory of Complicated Grief was used to define grief and complicated grief. We assessed sleep with the Pittsburgh Sleep Quality Index.

RESULTS

After 6 years, 3,511 (80% of survivors) underwent the follow-up interview. Complicated grief was cross-sectionally associated with shorter sleep duration and lower sleep quality. These associations were explained by the presence of depressive symptoms. The prospective analyses showed that sleep duration and sleep quality did not decline further during follow-up of persons who experienced grief or complicated grief.

CONCLUSION

In community-dwelling, middle-aged and older adults, persons with normal and complicated grief had both a shorter sleep duration and a lower sleep quality, mainly explained by depressive symptoms. However, prospective analyses showed that sleep quality and sleep duration do not decline further in persons with normal grief and complicated grief.

[Stress levels and coping behavior in patients with chronic insomnia]

AIM

To assess stress level and coping strategies in chronic insomnia as its potential psychological factors.

MATERIAL AND METHODS

The study group included 29 patients (19 women), aged 18-55 years old (mean age 33.1±2.1 years), with chronic insomnia diagnosed in accordance with the International Classification of Sleep Disorders III. The control group was formed by 32 subjects (11 men), aged 18-55 years old (mean age 31.5±2.0 years), without sleep disorders. Insomnia Severity Index and polysomnography were used to evaluate sleep quality. Stress level and coping strategies were assessed via an interview (stressfull life events during last year, their duration, their controllability, unexpectedness, and outcome), and by 'Level of subjective control' and 'Ways of coping questionnaires'.

RESULTS

Both groups were comparable by the mean number of significant events during last year (4.97±0.34 vs 4.72±0.23, p=0.54). Patients with insomnia more often reported the loss of a relative (p=0.04), while controls more frequently reported positive events, such as pregnancy (p=0.007) or wedding (p=0.02) among close ones. Insomniacs more often described the stressful events as uncontrolled (p<0.001) and prolonged (p<0.001). They demonstrated lower indices of all the scales of the 'Level of subjective control', questionnaire except the scale of interpersonal attitudes. They rarely implemented confrontive coping (p=0.001), seeking social support (p<0.001), accepting responsibility (p<0.001) and positive reappraisal (p<0.001).

CONCLUSIONS

The interpretation of stressful events and personal response in insomnia patients might be considered as psychological risk factors for insomnia development.

Mending the heart and mind during times of loss: A review of interventions to improve emotional well-being during spousal bereavement

Spousal loss is one of life's greatest stressors. Bereaved spouses are at risk for aberrant cognitive and affective processing. Recent work in psychoneuroimmunology and cognitive neuroscience reveals physiological biomarkers and neural mechanisms underlying acute distress and grief during bereavement that may represent targets for future interventions. We review evidence from existing pharmacological and psychotherapeutic treatment approaches for normal bereavement, complicated grief, and bereavement-related depression. We propose promising future directions, namely the development and empirical validation of novel, personalised cognitive and neurostimulatory interventions to promote adaptive emotion regulation and reduce depressive symptoms following spousal loss. Future work may substantiate which interventions to improve emotional and physical health will be best matched to the needs of a particular surviving spouse.

Active ageing, emotional care and the threat of stigma: Identity management in older adults using sleeping medication long-term

Amid fears about the medicalisation of old age, the high prevalence of sleeping medication use in older cohorts is a significant public health concern. Long-term use is associated with a plethora of negative effects, such as cognitive impairment and risk of addiction. However, little is known about the lived experience of older adults using sleeping medication longer term. Episodic interviews lasting approximately 90 minutes were conducted with 15 independently living adults, aged 65-88 years, who were using sedative-hypnotic or tricyclic sleeping medication for more than 11 years on average. Thematic analysis shows that participants divided their rationale for use into two temporal periods: (1) to ensure physical ability in the daytime and (2) to ensure emotional stability at night. Long-term sleeping medication was thus characterised as a form of 'emotional self-management' of the negative emotions associated with later life, blotting out feelings of loss and loneliness by inducing sleep. Participants feared loss of access to their medication 'supply', employing strategies to ensure its continuity, while expressing shame about their dependence. However, identity management, in the form of explanations, minimisations and social comparisons, functioned to downplay their addiction. Through this, long-term sleeping medication users were able to elude the spoiled identities and multiple stigmas of both the 'out of control' addict and the unsuccessful older adult by asserting a positive identity; that of the 'new' older adult, actively medicating for success both day and night.

Cognitive Behavioral Therapy for Sleep in Cancer Patients: Research, Techniques, and Individual Considerations

This article reviews cognitive behavioral therapy techniques for sleep in the cancer realm. There are unique factors associated with cancer that can exacerbate sleep issues. Stimulus control, sleep restriction, relaxation, paradoxical intention, and cognitive therapy are discussed as specific components of cognitive behavioral therapy for sleep, and practical techniques for implementation are provided. Individual considerations in implementing these techniques are also discussed, including factors such as age, ethnicity, gender, relationship status, educational level, work status, cancer history, pharmacologic treatments, and health beliefs.

Design and Rationale for a Technology-based Healthy Lifestyle Intervention in Older Adults Grieving the Loss of a Spouse

Introduction

Experiencing the death of a spouse during late life is associated with an increased risk of developing debilitating mental health problems. Healthy lifestyle practices, such as regular exercise, healthy eating, and good sleep hygiene are promising strategies to influence the mental health and associated physical symptoms of late-life spousal bereavement.

Objective

This paper describes the design and rationale of an intervention development study addressing selective and indicated prevention of depression, anxiety, and/or complicated grief disorder(s) among adults 60 years and older who are grieving the recent loss (within 8 months) of a spouse or partner.

Methods

In Phase I, now complete, we developed and standardized behavioral self-monitoring of daily lifestyle choices via an electronic diary (BSM) and the combined BSM + motivational interviewing-based lifestyle coaching (BSM+MI) to be administered to participants grieving the loss of loved one. In Phase II, we have been implementing the interventions in a randomized controlled trial and addressing challenges related to recruitment. Randomization is to one of three cells: BSM, BSM+MI, or an enhanced usual care condition.

Discussion

Several challenges in implementing our lifestyle interventions to older widow(er)s who are at risk for common mental disorders have been identified. Direct outreach to hospice organizations is an effective way to identify older adults in the early months following spousal death. Results from study may advance the field of grief support and promote a healthy adaptation to widowhood.

Hallucinations in Healthy Older Adults: An Overview of the Literature and Perspectives for Future Research

KEY POINTS

➢ Studies suggest a substantial minority of healthy older adults have hallucinatory experiences, in line with existing evidence on hallucinations in other age groups, though it is still unclear if hallucination prevalence increases or declines with age in older cohorts.

➢ Stigma attached to both hallucinations and ageing leads to considerable under-reporting of these experiences in healthy older adults and may negatively bias how professionals, family members, and the public respond.

➢ Why and when hallucinations in healthy older adults remit, persist, or progress to other clinical disorders remains poorly understood.

➢ Current evidence points to a range of factors associated with hallucinations in older adults including decline in sensory or cognitive functioning, poor sleep, and psychosocial stressors (e.g., social isolation, loneliness, and bereavement), highlighting the need for accurate assessment and tailored interventions.

Hallucinations, though common in youth and younger adults, are not the preserve of these age groups. Accumulating evidence shows that hallucinatory experiences are also present at surprisingly high rates in healthy older adults in the general community. Furthermore, stigma and misunderstanding of hallucinations, together with ageism, may lead to under-reporting of these experiences by older adults, and misdiagnosis or mismanagement by health and mental health practitioners. Consequently, improved public and professional knowledge is needed about the nature and significance of hallucinations with advancing age. The purpose of this review is to provide a comprehensive overview, and critical analysis, of research on the prevalence, psychosocial, and neurobiological factors associated with hallucinations in people aged 60 years and over. To the best of our knowledge, this is the first review of its kind in the literature. The evidence supports a dynamic conceptualization of hallucinations, in which the emergence of hallucinations is viewed as a balance between the sensory, cognitive, or social impairments accompanying advancing age and the degree to which compensatory processes elicited by these impairments are successful. We briefly summarize the implications of the literature for aged care services and interventions, and stress that far more studies are needed in this important field of research.

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.

Daily Social Contact in Relation to Sleep: The Role of Age

OBJECTIVES

To examine how social contact during daily activities differs by age and relates to sleep outcomes.

METHODS

Fifty younger (M = 19.9 years, SD = 2.76) and 48 older (M = 67.6 years, SD = 6.63), community-dwelling adults completed the Social Rhythm Metric-17 and daily sleep diary online for 14 days.

RESULTS

Younger adults completed a greater proportion of activities with active others than older adults. Age significantly interacted with the proportion of activities completed alone, β = -.77, p = .04. Alone activities negatively predicted total sleep time in older, not younger adults.

DISCUSSION

Social contact, or lack thereof, is important for sleep, particularly for older adults who may be more prone to aloneness due to life course events.

Relationships between sleep quality and brain volume, metabolism, and amyloid deposition in late adulthood

Recent studies in mouse models of Alzheimer's disease (AD) and in humans suggest that sleep disruption and amyloid-beta (Aβ) accumulation are interrelated, and may, thus, exacerbate each other. We investigated the association between self-reported sleep variables and neuroimaging data in 51 healthy older adults. Participants completed a questionnaire assessing sleep quality and quantity and underwent positron emission tomography scans using [18F]florbetapir and [18F]fluorodeoxyglucose and an magnetic resonance imaging scan to measure Aβ burden, hypometabolism, and atrophy, respectively. Longer sleep latency was associated with greater Aβ burden in prefrontal areas. Moreover, the number of nocturnal awakenings was negatively correlated with gray matter volume in the insular region. In asymptomatic middle-aged and older adults, lower self-reported sleep quality was associated with greater Aβ burden and lower volume in brain areas relevant in aging and AD, but not with glucose metabolism. These results highlight the potential relevance of preserving sleep quality in older adults and suggest that sleep may be a factor to screen for in individuals at risk for AD.

Sleep Disturbances in the Elderly

Sleep disturbances are a common presenting symptom of older-age adults to their physicians. This article explores normal changes in sleep pattern with aging and primary sleep disorders in the elderly. Behavioral factors and primary psychiatric disorders affecting sleep in this population are reviewed. Further discussion examines sleep changes associated with 2 common forms of neurocognitive disorder: Alzheimer disease and Lewy Body Dementia. Common medical illnesses in the elderly are discussed in relation to sleep symptoms. Nonpharmacological and pharmacologic treatment strategies are summarized, with emphasis placed on risk of side effects in older adults. Future targets are considered.

Association between depressive symptoms and changes in sleep condition in the grieving process

PURPOSE

Bereaved families often suffer from insomnia and depression. However, the associations between depressive state and changes in sleep condition during the grieving process have not been investigated. This study aimed to clarify the prevalence of insomnia symptoms and to explore associations between present depressive state and changes in sleep condition in the grieving process in bereaved families of Japanese patients with cancer.

METHODS

A cross-sectional, multicenter survey was conducted in 103 certified palliative care units. A questionnaire asking insomnia symptoms and depressive symptoms by the Center for Epidemiological Studies Depression Scale (CES-D) was mailed to bereaved families (N = 987). The association between present depressive state (CES-D ≥7) and sleep conditions in the grieving process were analyzed.

RESULTS

A total of 561 families were enrolled for analysis. Fifty-three percent of family members were considered to be in a depressive state at the time of the investigation. Prevalence of past insomnia was 86.5% at "within a few weeks before the patient's death" (T1) and 84.5% at "within 6 months after the patient's death" (T2) in all bereaved family members. However, in contrast to decreased severity of insomnia between T1 and T2 in the non-depressive group (p < 0.05), severity of insomnia was unchanged in the depressive group during this period (p = 0.139).

CONCLUSIONS

Insomnia symptoms are highly prevalent and may be associated with posthumous depressive state in bereaved Japanese families. These results suggest the need for careful observation of changes in sleep condition during the grieving process.

The impact of mid- and late-life loss on insomnia: findings from the health and retirement study, 2010 cohort

Bereavement and insomnia are both well-documented risk factors for illness. We use cohort data to estimate risk of insomnia after death of a family member among adults aged 50 to 70 years. Each day, 6700 persons die in the United States. During the next 20 years, this number will increase. In this cohort, any loss increases the likelihood of insomnia. The highest rates of insomnia occur among women aged 50 to 59 years; men aged 65 to 70 years, and persons reporting death of a spouse/partner or child. Physical activity reduces this risk by one-third. Bereavement is a public health issue requiring a targeted response.

The effect of widowhood on husbands' and wives' physical activity: the Cardiovascular Health Study

This prospective study examined the effect of widowhood on physical activity by comparing widowed elders to health status-, age-, and sex-matched married controls. Participants included 396 married controls and 396 widows/widowers age 64-91 (M age = 72.7 years) who experienced the death of their spouse while participating in the Cardiovascular Health Study. Compared to married controls, widowed men, but not women, were more likely to increase their physical activity following the death of their spouse. However, this increased level of activity was not sustained and declines as time since spousal death passes. Moreover, during the year before spousal death, soon-to-be widowed men, but not women, increase their physical activity. Our results suggest that widowed men experience significant changes in physical activity and that the transition to widowhood contribute to these changes.

Marital status and outcome of patients presenting with acute coronary syndrome: an observational report

BACKGROUND & HYPOTHESIS: Data on the clinical characteristics and outcome of patients presenting with acute coronary syndrome (ACS) according to their marital status is not clear.

METHODS

A total of 5334 patients presenting with ACS in 65 hospitals in 6 Middle East countries in the 2nd Gulf Registry of Acute Coronary Events (Gulf RACE-2) were studied according to their marital status (5024 married, 100 single, and 210 widowed patients).

RESULT

When compared to married patients, widowed patients were older and more likely to be female. Widowed patients were more likely to have diabetes mellitus, hypertension, history of heart failure, and peripheral vascular disease and were less likely to be tobacco users when compared to the other groups. Widowed patients were also more likely to present with atypical symptoms and have advanced Killip class. Widowed patients were more likely to present with non-ST-elevation myocardial infarction (NSTEMI) when compared to the other 2 groups. Widowed patients were more likely to have heart failure (P = 0.001), cardiogenic shock (P = 0.001), and major bleeding (P = 0.002) when compared to the other groups. No statistically significant difference was observed in regard to duration of hospital stay, door to needle time in STEMI patients, or cardiac arrhythmias between the various groups. Widowed patients had higher in-hospital, 30-day, and 1-year mortality rates (P = 0.001). Marital status was an independent predictor for in-hospital mortality.

CONCLUSION

Widowed marital status was associated with worse cardiovascular risk profile, and worse in-hospital and 1-year outcome. Future work should be focused on whether the provision of psychosocial support will result in improved outcomes among this high-risk group.

Physiological correlates of bereavement and the impact of bereavement interventions

The death of a loved one is recognized as one of life's greatest stresses, with reports of increased mortality and morbidity for the surviving spouse or parent, especially in the early months of bereavement. The aim of this paper is to review the evidence to date to identify physiological changes in the early bereaved period, and evaluate the impact of bereavement interventions on such physiological responses, where they exist. Research to date suggests that bereavement is associated with neuroendocrine activation (cortisol response), altered sleep (electroencephalography changes), immune imbalance (reduced T-lymphocyte proliferation), inflammatory cell mobilization (neutrophils), and prothrombotic response (platelet activation and increased vWF-ag) as well as hemodynamic changes (heart rate and blood pressure), especially in the early months following loss. Additional evidence suggests that bereavement interventions have the potential to be of value in instances where sleep disturbance becomes a prolonged feature of complicated grief, but have limited efficacy in maintaining immune function in the normal course of bereavement.
