A Six-Year Prospective Study of the Prognosis and Predictors in Patients With Late-Life Depression

Neural Functioning in Late-Life Depression: An Activation Likelihood Estimation Meta-Analysis

Late-life depression (LLD) is a relatively common and debilitating mental disorder, also associated with cognitive dysfunctions and an increased risk of mortality. Considering the growing elderly population worldwide, LLD is increasingly emerging as a significant public health issue, also due to the rise in direct and indirect costs borne by healthcare systems. Understanding the neuroanatomical and neurofunctional correlates of LLD is crucial for developing more targeted and effective interventions, both from a preventive and therapeutic standpoint. This ALE meta-analysis aims to evaluate the involvement of specific neurofunctional changes in the neurophysiopathology of LLD by analysing functional neuroimaging studies conducted on patients with LLD compared to healthy subjects (HCs). We included 19 studies conducted on 844 subjects, divided into 439 patients with LLD and 405 HCs. Patients with LLD, compared to HCs, showed significant hypoactivation of the right superior and medial frontal gyri (Brodmann areas (Bas) 8, 9), left cingulate cortex (BA 24), left putamen, and left caudate body. The same patients exhibited significant hyperactivation of the left superior temporal gyrus (BA 42), left inferior frontal gyrus (BA 45), right anterior cingulate cortex (BA 24), right cerebellar culmen, and left cerebellar declive. In summary, we found significant changes in activation patterns and brain functioning in areas encompassed in the cortico-limbic-striatal network in LLD. Furthermore, our results suggest a potential role for areas within the cortico-striatal-cerebellar network in the neurophysiopathology of LLD.

Mapping 15-year depressive symptom transitions in late life: population-based cohort study

BACKGROUND

The longitudinal course of late-life depression remains under-studied.

AIMS

To describe transitions along the depression continuum in old age and to identify factors associated with specific transition patterns.

METHOD

We analysed 15-year longitudinal data on 2745 dementia-free persons aged 60+ from the population-based Swedish National Study on Aging and Care in Kungsholmen. Depression (minor and major) was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision; subsyndromal depression (SSD) was operationalised as the presence of ≥2 symptoms without depression. Multistate survival models were used to map depression transitions, including death, and to examine the association of psychosocial (social network, connection and support), lifestyle (smoking, alcohol consumption and physical activity) and clinical (somatic disease count) factors with transition patterns.

RESULTS

Over the follow-up, 19.1% had ≥1 transitions across depressive states, while 6.5% had ≥2. Each additional somatic disease was associated with a higher hazard of progression from no depression (No Dep) to SSD (hazard ratio 1.09; 1.07-1.10) and depression (Dep) (hazard ratio 1.06; 1.04-1.08), but also with a lower recovery (HRSSD-No Dep 0.95; 0.93-0.97 [where 'HR' refers to 'hazard ratio']; HRDep-No Dep 0.96; 0.93-0.99). Physical activity was associated with an increased hazard of recovery to no depression from SSD (hazard ratio 1.49; 1.28-1.73) and depression (hazard ratio 1.20; 1.00-1.44), while a richer social network was associated with both higher recovery from (HRSSD-No Dep 1.44; 1.26-1.66; HRDep-No Dep 1.51; 1.34-1.71) and lower progression hazards to a worse depressive state (HRNo Dep-SSD 0.81; 0.70-0.94; HRNo Dep-Dep 0.58; 0.46-0.73; HRSSD-Dep 0.66; 0.44-0.98).

CONCLUSIONS

Older people may present with heterogeneous depressive trajectories. Targeting the accumulation of somatic diseases and enhancing social interactions may be appropriate for both depression prevention and burden reduction, while promoting physical activity may primarily benefit recovery from depressive disorders.

A Remotely Delivered, Personalized Music Therapy Pilot Intervention for Lonely Older Adults During the Covid-19 Pandemic

Introduction

This study investigated a remotely delivered, therapist-facilitated, personalized music listening intervention for community-dwelling older adults experiencing loneliness during the Covid-19 pandemic. We assessed its feasibility and individuals' experiences of social connection and emotional well-being during the intervention.

Methods

Ten cognitively unimpaired older adults who endorsed loneliness completed eight weekly sessions with a board-certified music therapist via Zoom. Participants were guided in developing two online personalized music playlists and were asked to listen to playlists for at least one hour daily. Feasibility metrics were attendance, accessibility, and compliance rates. Post-study interview responses were analyzed using a rapid qualitative methodology. Exploratory pre- and post-study measures of loneliness and other aspects of psychological well-being were obtained using validated questionnaires.

Results

Ten participants (mean age 75.38 [65 to 85] years, 80% women) were enrolled from March to August 2021. Attendance and compliance rates were 100% and the accessibility rate was 90%. Most participants associated music with positive memories before the program and many reported that the intervention prompted them to reconnect with music or listen to music with greater intention. They cited increased connection from interacting with the music therapist and the music itself, as well as specific positive emotional impacts from integrating music into their daily lives. Median pre- to post-questionnaire measures of psychological function all changed in an improved direction.

Discussion

Remotely delivered music therapy may be a promising intervention to promote regular music listening and socioemotional well-being in lonely older adults.

A Middle-Range Theory of Social Isolation in Chronic Illness

Chronic illnesses and social isolation are major public phenomena that drive health and social policy worldwide. This article describes a middle-range theory of social isolation as experienced by chronically ill individuals. Key concepts include social disconnectedness, loneliness, and chronic illness. Antecedents of social isolation include predisposing factors (e.g., ageism and immigration) and precipitating factors (e.g., stigma and grief). Outcomes of social isolation include psychosocial responses (e.g., depression and quality of life), health-related behaviors (i.e., self-care), and clinical responses (e.g., cognitive function and health service use). Possible patterns of social isolation in chronic illness are described.

Effectiveness of continuity of care in reducing depression symptoms in elderly: A systematic review and meta-analysis

BACKGROUND

Depression affects 10%-20% of older adults worldwide. The course of late-life depression (LLD) is often chronic, with a poor long-term prognosis. Lower treatment adherence, stigma, and suicide risk lead to significant challenges in the continuity of care (COC) for patients with LLD. Elderly patients with chronic diseases can benefit from COC. As a common chronic disease of the elderly, whether depression can also benefit from COC has not been systematically reviewed.

METHODS

Systematic literature search in Embase, Cochrane Library, Web of Science, Ovid, PubMed and Medline. Randomized Controlled Trials (RCTs) on the intervention effects of COC and LLD, published on 12 April 2022, were selected. Two independent researchers made research choices based on consensus. An RCT with COC as an intervention measure for the elderly with depression 60 years old was the inclusion criteria.

RESULTS

A total of 10 RCTs involving 1557 participants were identified in this study. The findings showed that: (1) COC significantly reduced depressive symptoms compared to usual care (standardized mean difference [SMD] = -0.47, 95% confidence interval: -0.63 to -0.31), with the best improvement at 3- to 6-month follow-up; (2) The reduction in depressive symptoms was more pronounced for patients with comorbid chronic conditions with LLD (SMD = -0.93, 95% CI: -1.18 to -0.68); (3) COC was more effective than other regions for LLD in Europe and the Americas (SMD = -0.84, 95% CI: -1.07 to -0.61); and (4) COC had a positive impact on the quality of life of patients with LLD (SMD = 0.21, 95% CI: 0.02-0.40).

LIMITATIONS

The included studies included several multi-component interventions with widely varying methods. Therefore, it was almost impossible to analyze which of these interventions had an impact on the assessed outcomes.

CONCLUSIONS

This meta-analysis shows that COC can significantly reduce depressive symptoms and improve quality of life in patients with LLD. However, when treating and caring for patients with LLD, health care providers should also pay attention to timely adjustments of intervention plans according to follow-up, synergistic interventions for multiple co-morbidities, and actively learning from advanced COC programs at home and abroad to improve the quality and effectiveness of services.

[Prognosis of late-life depression: clinical and immunological features]

OBJECTIVE

To study the outcomes of depression at a late age during a 3-year prospective follow-up in patients with various immunophenotypes.

MATERIAL AND METHODS

A cohort of patients with depressive disorders who were treated in a gerontopsychiatric hospital and re-examined after 1 and 3 years. The group with immunophenotype A (with increased activity of leukocyte elastase (LE) and complex depressions, comorbid with anxiety and senesto-hypochondriac disorders) included 20 people: 6 men (30%) and 14 women (70%), median age was 68 years. A depressive episode (DE) was diagnosed in 13 patients (65%) with recurrent depressive disorder (RDD) and in 7 patients (35%) with bipolar affective disorder (BAD). The group with immunophenotype B (with reduced activity of LE and prolonged apathetic-adynamic depression) included 31 people: 10 men (32.3%) and 21 women (67.7%), the median age was 68 years. DE was diagnosed in 20 patients (64.5%) with RDD, 9 patients (29%) with BAD, and in 2 patients (6.5%) with a single DE. The patients were examined using clinical, psychometric, immunological and clinical- follow-up methods (after 1 and 3 years).

RESULTS

More favorable course of the disease with the formation of high-quality remission was observed in patients with immunophenotype A (95% of cases after 1 and 3 years; χ2=10.44; p=0.001 and χ2=11.97; p=0.001, respectively). In patients with immunophenotype B, an unfavorable course of the disease prevailed (83.9 and 87.1% of cases after 1 and 3 years) with the formation of low-quality remissions (with residual depressive disorders, the development of repeated depressive phases and chronification of depression).

CONCLUSION

The study revealed the relationship between clinical and biological features and the course of late-life depression.

The effectiveness of off-label dopamine stimulating agents in depressive disorder: A systematic review and meta-analysis

The chronicity of depressive disorders is a major problem. Dopamine stimulating agents (DSA) are suggested to hold a promising potential in depression management, particularly in older adults, in whom dopamine deficiency due to aging may be an underlying cause. More evidence is needed to support these drugs in the management of depression. Therefore, we conducted a systematic literature review and meta-analysis. Data was extracted from eighteen randomized-controlled-trials and eight open-label-studies. Additional meta-regression-analyses were performed to examine superiority of monotherapy versus augmentation, and to rule out a putative age effect. DSA were found to reduce depressive symptoms (SMD=-0.26, 95%CI[-0.43;-0.10]). Heterogeneity was high and a significant Egger's test indicated publication bias. Adjustment for missing studies, using trim-and-fill-methodology, reduced the effect size (SMD=-0.17, 95%CI[-0.39;0.05]), which lost statistical significance. Removing the outlier study from the analysis, the effect size remained marginally small, but was statistically-significant (SMD=-0.17, 95%CI[-0.31;-0.02]). Neither augmentation nor monotherapy was superior. No age effect was found. It can be concluded that off-label DSA are overall effective in reducing depressive symptoms. However, the evidence is weak, regarding the publication bias, and modest-to-weak treatment effects. Well-designed high-quality trials are highly needed, before dopamine stimulating agents can be adequately positioned in future depression treatment protocols.

A Longitudinal Examination of the Association Between Loss of Control and Loneliness Among Older Adults Diagnosed with Cancer

Objectives: The objective of this paper is to examine whether feeling a loss of control over one's life is associated with an increased risk for loneliness among those diagnosed with cancer. Method: We draw on data from the Health and Retirement Study to identify three baseline and follow-up cohorts of cancer survivors age 50 and older. Ordinary least squared regression is used to examine predictors for future loneliness. Results: Upon adjusting for other known predictors of loneliness, feelings of loss of control was significantly predictive of loneliness among 4-year cancer survivors. Discussion: Social workers and other health care practitioners should seek to provide evidence-based interventions to reduce the risk for loneliness for cancer survivors feeling a loss of control.

Association of Polymorphism within the Putative miRNA Target Site in the 3'UTR Region of the DRD2 Gene with Neuroticism in Patients with Substance Use Disorder

The study aims at looking into associations between the polymorphism rs6276 that occurs in the putative miRNA target site in the 3'UTR region of the DRD2 gene in patients with substance use disorder (SUD) comorbid with a maniacal syndrome (SUD MANIA). In our study, we did not state any essential difference in DRD2 rs6276 genotype frequencies in the studied samples of SUD MANIA, SUD, and control subjects. A significant result was found for the SUD MANIA group vs. SUD vs. controls on the Neuroticism Scale of NEO FFI test, and DRD2 rs6276 (p = 0.0320) accounted for 1.7% of the variance. The G/G homozygous variants were linked with lower results on the neuroticism scale in the SUD MANIA group because G/G alleles may serve a protective role in the expression of neuroticism in patients with SUD MANIA. So far, there have been no data in the literature on the relationship between the miRSNP rs6276 region in the DRD2 gene and neuroticism (personal traits) in patients with a diagnosis of substance use disorder comorbid with the affective, maniacal type disturbances related to SUD. This is the first report on this topic.

Determinants and consequences of polypharmacy in patients with a depressive disorder in later life

OBJECTIVES

Polypharmacy and late-life depression often congregate in the geriatric population. The primary objective is to identify determinants of polypharmacy in patients with depression, and second to examine polypharmacy in relation to various clinical phenotypes of depression and its course.

METHODS

A longitudinal observational study using data of the Netherlands Study of Depression in Older persons (NESDO) including 375 patients with depression ≥ 60 years and 132 non-depressed comparisons. Linear and logistic regression were used to analyze both polypharmacy (dichotomous: ≥5 medications) and number of prescribed drugs (continuous) in relation to depression, various clinical phenotypes, and depression course.

RESULTS

Polypharmacy was more prevalent among patients with depression (46.9%) versus non-depressed comparisons (19.7%). A lower level of education, lower cognitive functioning, and more chronic diseases were independently associated with polypharmacy. Adjusted for these determinants, polypharmacy was associated with a higher level of motivational problems, anxiety, pain, and an earlier age of onset. A higher number of drugs was associated with a worse course of late-life depression (OR = 1.24 [95% CI: 1.03-1.49], p = 0.022).

CONCLUSION

Older patients with depression have a huge risk of polypharmacy, in particular among those with an early onset depression. As an independent risk factor for chronic depression, polypharmacy needs to be identified and managed appropriately. Findings suggest that depression moderates polypharmacy through shared risk factors, including motivational problems, anxiety, and pain. The complex interaction with somatic health burden requires physicians to prescribe medications with care.

The longitudinal association between loneliness and depressive symptoms in the elderly: a systematic review

OBJECTIVE

Loneliness and the onset of depression in old age are growing problems related to the greater life expectancy nowadays. This review investigated the longitudinal association between loneliness and depressive symptoms in the elderly.

DESIGN

A comprehensive search was conducted using three databases (Scopus, PsycInfo, and PubMed) combing for empirical studies published up until July 2020. A total of 4.549 abstracts and 221 full-text articles were assessed. Three authors independently reviewed titles and abstracts; disagreements were resolved by consensus.

RESULTS

Ten studies were included in the final review. We identified two categories of studies based on the outcome considered in each article: 1) the longitudinal effect of loneliness on depressive symptoms and 2) the clinical course of depression and its association with loneliness. All the articles reported a significant and positive association between loneliness and depressive symptoms in their longitudinal design research, ranging from an odds ratio of 0.41 to 17.76. The heterogeneity regarding the effect size in the analyses can be explained by the multifactorial design implemented by most of the studies included.

CONCLUSIONS

Future research should investigate the moderators' role and how it may influence the longitudinal association between loneliness and depression over the years.

Subtyping late-life depression according to inflammatory and metabolic dysregulation: a prospective study

BACKGROUND

Inflammation and metabolic dysregulation are age-related physiological changes and are associated with depressive disorder. We tried to identify subgroups of depressed older patients based on their metabolic-inflammatory profile and examined the course of depression for these subgroups.

METHODS

This clinical cohort study was conducted in a sample of 364 depressed older (⩾60 years) patients according to DSM-IV criteria. Severity of depressive symptoms was monitored every 6 months and a formal diagnostic interview repeated at 2-year follow-up. Latent class analyses based on baseline metabolic and inflammatory biomarkers were performed. Adjusted for confounders, we compared remission of depression at 2-year follow-up between the metabolic-inflammatory subgroups with logistic regression and the course of depression severity over 2-years by linear mixed models.

RESULTS

We identified a 'healthy' subgroup (n = 181, 49.7%) and five subgroups characterized by different profiles of metabolic-inflammatory dysregulation. Compared to the healthy subgroup, patients in the subgroup with mild 'metabolic and inflammatory dysregulation' (n = 137, 37.6%) had higher depressive symptom scores, a lower rate of improvement in the first year, and were less likely to be remitted after 2-years [OR 0.49 (95% CI 0.26-0.91)]. The four smaller subgroups characterized by a more specific immune-inflammatory dysregulation profile did not differ from the two main subgroups regarding the course of depression.

CONCLUSIONS

Nearly half of the patients with late-life depressions suffer from metabolic-inflammatory dysregulation, which is also associated with more severe depression and a worse prognosis. Future studies should examine whether these depressed older patients benefit from a metabolic-inflammatory targeted treatment.

Risk factors for suicidal behaviour in late-life depression: A systematic review

BACKGROUND

Suicide is a leading cause of preventable death worldwide, with its peak of maximum incidence in later life. Depression often puts an individual at higher risk for suicidal behaviour. In turn, depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing.

AIM

To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults, and to examine the effects of depression treatment to tackle suicide behaviour in this population.

METHODS

A systematic review of empirical studies, published from 2000 onwards, was conducted. Suicidal behaviour was addressed considering its varying forms (i.e., wish to die, ideation, attempt, and completed suicide).

RESULTS

Thirty-five papers were selected for review, comprising both clinical and epidemiological studies. Most of studies focused on suicidal ideation (60%). The studies consistently pointed out that the risk was related to depressive episode severity, psychiatric comorbidity (anxiety or substance use disorders), poorer health status, and loss of functionality. Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults. Finally, the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response. Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms.

CONCLUSION

To sum up, common and age-specific risk factors seem to be involved in suicide development in depressive older adults. A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

Perspectives on Mental Health Screening in the Audiology Setting: A Focus Group Study Involving Clinical and Nonclinical Staff

PURPOSE

Audiology clinical guidelines recommend the use of mental health screening tools; however, they remain underutilized in clinical practice. As such, psychological concerns are frequently undetected in adults with hearing loss. This study aimed to better understand audiology clinic staff's perspectives (including audiologists, audiometrists, reception staff, and clinic managers) on how to improve detection of poor mental health by (a) exploring the role of audiology clinic staff in detecting psychological concerns in adults with hearing loss and (b) investigating the appropriateness, acceptability, and usability of several screening tools in an audiology setting.

METHOD

Eleven audiology clinic staff (M _age = 33.9 ± 7.3, range: 25-51 years) participated in a semistructured focus group. First, participants discussed the role of audiology clinic staff in detecting psychological difficulties in adults with hearing loss, including current practices and needs for improving practices. Second, participants discussed the appropriateness, acceptability, and usability of nine standardized mental health screening tools commonly used in wider health care settings.

RESULTS

Audiology clinic staff described their role in being aware of, and detecting, psychological difficulties, as well as their part in promoting an understanding of the link between hearing loss and mental health. Participants described the need to provide support following detection, and highlighted barriers to fulfilling these roles. The use of mental health screening tools was considered to be client and context specific. The language used within the screener was identified as an important factor for its acceptability by audiology clinic staff.

CONCLUSIONS

Audiology clinic staff acknowledged that they have an important role to play in the detection of psychological difficulties and identified the core barriers to using screening tools. Future research may explore the possibility of developing a mental health screening tool specific to the unique experiences of adults with comorbid hearing loss and mental health concerns.

A randomized controlled trial of cognitive control training (CCT) as an add-on treatment for late-life depression: a study protocol

BACKGROUND

Already a major health concern, late-life depression (LLD) is expected to form an increasing problem in the aging population. Moreover, despite current treatments, LLD is associated with a poor long-term prognosis and high rate of chronicity. Treatment provision and treatment accordingly warrant improvement, where add-on treatments might contribute to the efficacy of conventional therapies. Although it is known that impaired cognitive control contributes to LDD, it is not targeted sufficiently by current interventions. Research on cognitive control training (CCT) shows promising results on depressive symptoms, cognitive performance, and overall functioning. However, further research is needed to determine the long-term effects of CCT on LLD, its cost-effectiveness, and mechanisms of change.

METHODS

In the current multicenter randomized controlled trial (RCT) with a between-subjects design participants aged 60 years and over with a current LLD receiving treatment as usual (TAU) are randomized to add-on CCT or placebo training. Randomization is stratified by depression severity. Participants will receive eight online CCT or placebo sessions spread across four consecutive weeks. They will complete a post-training assessment after 1 month and three follow-up assessments scheduled three, six and 12 months after completing the training. We expect CCT and TAU to be more (cost-)effective in reducing depressive symptoms than placebo training and TAU. Additionally, we will be looking at secondary clinical, cognitive and global functioning outcomes and likely mechanisms of change (e.g., improved cognitive functioning, reduced rumination, and improved inhibition of negative stimuli).

DISCUSSION

The proposed RCT aims to contribute to the clinical and scientific knowledge on the long-term effects of CCT as an add-on treatment for LLD. Cost-effectiveness is particularly relevant considering the expected volume of the target demographic. The study will be a pragmatic trial with few inclusion restrictions, providing information on feasibility of web-based trainings in clinical settings. The outcomes are potentially generalizable to guidelines for treatment of LLD.

This trial is registered in the Netherlands Trial Register (code: NL7639 ). Registered 3 april 2019.

A 6-year prospective clinical cohort study on the bidirectional association between frailty and depressive disorder

INTRODUCTION

Depressive disorder has been conceptualised as a condition of accelerated biological ageing. We operationalised a frailty index (FI) as marker for biological ageing aimed to explore the bidirectional, longitudinal association between frailty and either depressive symptoms or depressive disorder.

METHODS

A cohort study with 6-year follow-up including 377 older (≥60 years) outpatients with a DSM-IV-defined depressive disorder and 132 never-depressed controls. Site visits at baseline, 2 and 6-year follow-up were conducted and included the CIDI 2.0 to assess depressive disorder and relevant covariates. Depressive symptom severity and mortality were assessed every 6 months by mail and telephone. A 41-item FI was operationalised and validated against the 6-year morality rate by Cox regression (HR_FI  = 1.04 [95% CI: 1.02-1.06]).

RESULTS

Cox regression showed that a higher FI was associated with a lower chance of remission among depressed patients (HR_FI  = 0.98 [95% CI: 0.97-0.99]). Nonetheless, this latter effect disappeared after adjustment for baseline depressive symptom severity. Linear mixed models showed that the FI increased over time in the whole sample (B[SE] = 0.94 (0.12), p < .001) with a differential impact of depressive symptom severity and depressive disorder. Higher baseline depressive symptom severity was associated with an attenuated and depressive disorder with an accelerated increase of the FI over time.

CONCLUSIONS

The sum score of depression rating scales is likely confounded by frailty. Depressive disorder, according to DSM-IV criteria, is associated with accelerated biological ageing. This argues for the development of multidisciplinary geriatric care models incorporating frailty to improve the overall outcome of late-life depression.

Social Support, Isolation, Loneliness, and Health Among Older Adults in the PRISM Randomized Controlled Trial

Objectives: Social isolation and loneliness are serious public health issues given the association with negative physical, mental; and cognitive health outcomes and increased risk for mortality. Due to changes in life circumstances many aging adults are socially isolated and experience loneliness. We examined the relationships among four correlated but distinct constructs: social network size, social support, social isolation, and loneliness as they relate to indices of health and wellbeing among diverse subpopulations of older adults. Guided by WHO's International Classification of Functioning, Disability and Health (ICF) we also examined factors that predict loneliness and social isolation. Methods: Analyses of baseline data from sample of older adults who participated in an intervention trial that examined the beneficial effects of a software system designed to support access to resources and information, and social connectivity. Participants included 300 individuals aged 65-98, who lived alone, were primarily of lower socio-economic status and ethnically diverse. Participants completed a demographics questionnaire, self-report measures of health, depression, social network size, social support, and loneliness. Results: Loneliness was strongly associated with depression and self-ratings of health. In turn, greater social isolation and less social support were associated with greater loneliness. Social isolation was associated with depression and lower self-ratings of health. The association between social isolation and health was mediated by loneliness. Individuals in the older cohorts (80+) reported less social support. With respect to loneliness, having a smaller social network, more functional limitations, and limitations in engaging meaningful activities was associated with higher levels of loneliness and greater social isolation. Conclusion: The findings underscore the importance of social connectively to wellbeing for older adults and suggest that those in the older cohorts, who have a small social network, and with greater physical and functional impairments may be particularly vulnerable to being socially isolated and lonely. The findings provide guidance for future interventions. In this regard, we discuss how Information and Communication Technologies (ICTs) may be used to promote social connectivity and engagement. Strategies to make the usability and availability of these applications for aging adults are highlighted.

Excess mortality in depressive and anxiety disorders: The Lifelines Cohort Study

Background

To examine the mortality risk of current and life-time depressive as well as anxiety disorders, whether this risk is moderated by sex or age, and whether this risk can be explained by lifestyle and/or somatic health status.

Methods

A cohort study (Lifelines) including 141,377 participants (18–93 years) which were followed-up regarding mortality for 8.6 years (range 3.0–13.7). Baseline depressive and anxiety disorders according to Diagnostic and Statistical Manual of Mental Disorders, fourth edition criteria were assessed with the Mini International Neuropsychiatric Interview and lifetime diagnoses by self-report. All-cause mortality was retrieved from Statistics Netherlands. Cox-regression was applied to calculate proportional hazard ratios, adjusted for lifestyle (physical activity, alcohol use, smoking, and body mass index) and somatic health status (multimorbidity and frailty) in different models.

Results

The mortality rate of depressive and anxiety disorders was conditional upon age but not on sex. Only in people below 60 years, current depressive and anxiety disorders were associated with mortality. Only depressive disorder and panic disorder independently predicted mortality when all mental disorders were included simultaneously in one overall model (hazard ratio [HR] = 2.18 [95% confidence intervals (CI): 1.56–3.05], p < 0.001 and HR = 2.39 [95% CI: 1.15–4.98], p = 0.020). Life-time depressive and anxiety disorders, however, were independent of each other associated with mortality. Associations hardly changed when adjusted for lifestyle characteristics but decreased substantially when adjusted for somatic health status (in particular physical frailty).

Conclusions

In particular, depressive disorder is associated with excess mortality in people below 60 years, independent of their lifestyle. This effect seems partly explained by multimorbidity and frailty, which suggest that chronic disease management of depression-associated somatic morbidity needs to be (further) improved.

Lower regional gray matter volume in the absence of higher cortical amyloid burden in late-life depression

Late-life depression (LLD) is associated with a risk of developing Alzheimer's disease (AD). However, the role of AD-pathophysiology in LLD, and its association with clinical symptoms and cognitive function are elusive. In this study, one hundred subjects underwent amyloid positron emission tomography (PET) imaging with [¹⁸F]-flutemetamol and structural MRI: 48 severely depressed elderly subjects (age 74.1 ± 7.5 years, 33 female) and 52 age-/gender-matched healthy controls (72.4 ± 6.4 years, 37 female). The Geriatric Depression Scale (GDS) and Rey Auditory Verbal Learning Test (RAVLT) were used to assess the severity of depressive symptoms and episodic memory function respectively. Amyloid deposition was quantified using the standardized uptake value ratio. Whole-brain voxel-wise comparisons of amyloid deposition and gray matter volume (GMV) between LLD and controls were performed. Multivariate analysis of covariance was conducted to investigate the association of regional differences in amyloid deposition and GMV with clinical factors, including GDS and RAVLT. As a result, there were no significant group differences in amyloid deposition. In contrast, LLD showed significant lower GMV in the left temporal and parietal region. GMV reduction in the left temporal region was associated with episodic memory dysfunction, but not with depression severity. Regional GMV reduction was not associated with amyloid deposition. LLD is associated with lower GMV in regions that overlap with AD-pathophysiology, and which are associated with episodic memory function. The lack of corresponding associations with amyloid suggests that lower GMV driven by non-amyloid pathology may play a central role in the neurobiology of LLD presenting as a psychiatric disorder.Trial registration: European Union Drug Regulating Authorities Clinical Trials identifier: EudraCT 2009-018064-95.

Social Disconnection in Late Life Mental Illness - Commentary From the National Institute of Mental Health

•Social disconnection – both objective social isolation as well as perceived social isolation (otherwise known as loneliness) – is a prevalent affliction among older adults, with profound effects on mental health. •Mechanistic understanding of how mental illness contributes to, is exacerbated by, or is otherwise linked to social disconnection remains elusive, and therapeutic interventions which leverage social connection to enhance compliance with or efficacy of mental health treatment, though promising, remain scarce. •The National Institute of Mental Health (NIMH) is committed to transforming the understanding and treatment of mental illnesses through basic and clinical research, paving the way for prevention, recovery, and cure. To translate basic knowledge into new methods for diagnosis, treatment, and prevention of mental illness demands appreciation for the broader milieu of social and environmental factors in which mental illness prevails – of which, social connection or disconnection is one.

Major Depressive Disorder in Older Patients as an Inflammatory Disorder: Implications for the Pharmacological Management of Geriatric Depression

Depression is a common and highly disabling condition in older adults. It is a heterogenous disorder and there is emerging evidence of a link between inflammation and depression in older patients, with a possible inflammatory subtype of depression. Persistent low-level inflammation, from several sources including psychological distress and chronic disease, can disrupt monoaminergic and glutaminergic systems to create dysfunctional brain networks. Despite the evidence for the role of inflammation in depression, there is insufficient evidence to recommend use of any putative anti-inflammatory agent in the treatment of depression in older adults at this stage. Further characterisation of markers of inflammation and stratification of participants with elevated rates of inflammatory markers in treatment trials is needed.

Grief and loss in old age: Exploration of the association between grief and depression

BACKGROUND

The proportion of older adults is increasing due to demographic changes. Depression belongs to the most common mental disorders in late life. The loss of an emotionally significant person is a risk factor for the development of depression. The aim of this study is to analyze the association between depression and grief burden resulting from loss. Based on prior evidence, we examined loneliness as a possible mediator and social support as possible moderator of this association.

METHODS

The cross-sectional analyses are based on a sample (N = 863) of study participants aged 75+ (M = 81.4 years, SD = 4.4, 62.2% female) with loss experience deriving from the multicenter prospective German cohort study AgeMooDe. Regression analyses (moderated mediation) were performed.

RESULTS

With increasing age (β = 0.10, p = .005) and grief burden (β = 0.33, p <. 001) depression severity increased. There was an indirect mediating effect of loneliness on the correlation of grief burden and depression (b = 0.04, CI [0.03, 0.05]), but no moderating effect of social support on the correlation of grief burden and loneliness. People living alone had a significantly higher risk of depression, increased loneliness and lack of social support.

LIMITATIONS

Assessments were based on self-reporting and recorded dimensionally. The cross-sectional design limits conclusions about directions and causality of associations. Sampling bias cannot be completely excluded.

CONCLUSION

The study provides empirical evidence and a better understanding of the association between grief and depression among the very old and the mediating role of loneliness.

Clinical characteristics of late-life depression predicting mortality

OBJECTIVE

Depression has been associated with increased mortality rates, and modifying mechanisms have not yet been elucidated. We examined whether specific subtypes or characteristics of late-life depression predict mortality.

METHODS

A cohort study including 378 depressed older patients according to DSM-IV criteria and 132 never depressed comparisons. The predictive value of depression subtypes and characteristics on the six-year mortality rate, as well as their interaction with somatic disease burden and antidepressant drug use, were studied by Cox proportional hazard analysis adjusted for demographic and lifestyle characteristics.

RESULTS

Depressed persons had a higher mortality risk than non-depressed comparisons (HR = 2.95 [95% CI: 1.41-6.16], p = .004), which lost significance after adjustment for age, sex, education, smoking, alcohol, physical activity, number of prescribed medications and somatic comorbidity. Regarding depression subtypes and characteristics, only minor depression was associated with a higher mortality risk when adjusted for confounders (HR = 6.59 [95% CI: 1.79-24.2], p = .005).

CONCLUSIONS

Increased mortality rates of depressed older persons seem best explained by unhealthy lifestyle characteristics and multiple drug prescriptions. The high mortality rate in minor depression, independent of these factors, might point to another, yet unknown, pathway towards mortality for this depression subtype. An explanation might be that minor depression in later life reflects depressive symptoms due to underlying aging-related processes, such as inflammation-based sickness behavior, frailty, and mild cognitive impairment, which have all been associated with increased mortality.

Social connectedness in adults with mental disorders: ecological validation of a conceptual framework for novel complex interventions

BACKGROUND

Social connectedness interventions may improve the clinical outcomes and personal recovery of adults with mental disorders but many interventions lack a clear theory-base and show limited effectiveness.

AIM

To evaluate the validity of a newly developed conceptual framework (the CIVIC framework: Closeness, Identity, Valued relationships, Involvement and Cared for and accepted) to function as the theory-base for novel social connectedness-based mental health interventions.

METHOD

Semi-structured interviews with adults with diagnostically heterogeneous mental disorders (n = 13) and mental health professionals (n = 9). Participants reported their social connectedness experiences, their views on the CIVIC framework and potential targets for new interventions. Sequential inductive and deductive thematic analyses were used. Data quality was assessed through respondent validation.

RESULTS

Both inductive and deductive analyses provided validation of the CIVIC framework. Additional themes of Stigma and Connectedness beyond social relationships were identified in the inductive analysis. Candidate interventions to target each CIVIC domain were identified.

CONCLUSIONS

The CIVIC framework demonstrates ecological validity and can therefore serve as the theory-base for the development of novel social connectedness-based interventions. This study indicates that interventions would be most effective when they incorporate evidence-based approaches which target each of the categories described by the CIVIC framework.

The influence of social, psychological, and cognitive factors on the clinical course in older patients with bipolar disorder

OBJECTIVES

Research on factors that contribute to recurrence in older adults with bipolar disorder (OABD) is sparse. Previous research showed that clinical factors (e.g., age of onset, lifetime psychotic features, and suicide risk) were not associated with the recurrence in OABD. In younger adults, worse social functioning, coping style, and worse cognitive functioning are found to be associated with an unfavorable course of bipolar disorder. Therefore, this study is focusing on social, psychological, and cognitive factors in OABD. More insight in these factors is essential in order to develop and further specify preventive and treatment interventions.

METHODS

Data were used from the Dutch Older Bipolars (DOBi) cohort study. We included 64 patients for 3-year follow-up measurements, who were divided in a recurrent group and a nonrecurrent group. Logistic regression analyses were conducted to assess associations between social, psychological, and cognitive factors, and nonrecurrence.

RESULTS

39.1% reported at least one recurrence during the 3-year follow-up period. No significant associations were found between the social, psychological, and cognitive factors and having a recurrence during the follow-up period.

DISCUSSION

Participants in the recurrent group were younger, more often female and less likely to have children. Our results suggest that results from the adult bipolar disorder population cannot be extrapolated to OABD patients, underlining the need for longitudinal studies in OABD.

Stages of major depressive disorder and behavioral multi-morbidities: Findings from nationally representative epidemiologic study

OBJECTIVE

To present a three stage-model of major depressive disorder (MDD) and evaluate differences in behavioral histories/experiences and multi-morbidities between stages.

METHODS

We used data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III, a nationally representative cross-sectional survey of US adults (n = 36,309). Based on DSM-5 diagnostic criteria, we identified and compared three groups of adults with MDD histories: 1) new onset MDD (n = 509; 5.6%); 2) chronic MDD (n = 3,871; 46.1%); and 3) recovered from MDD (n = 3,673; 48.3%). Multivariable analyses tested independent group differences in behavioral histories/experiences and diagnostic multi-morbidities between 1) recovered MDD vs. new onset MDD; 2) chronic MDD vs. new onset MDD; and 3) recovered MDD vs. chronic MDD.

RESULTS

Adults who have recovered from MDD as compared to those with chronic MDD were 2.5 times more likely to have recovered from two or more psychiatric disorders in addition to MDD (95% confidence intervals [CI]=1.76-3.61) and from alcohol use disorder (adjusted odds ratio [AOR]=1.28; 95% CI=1.08-1.52). They were also less likely than those with chronic MDD to have borderline personality disorder (p<0.001), pain (p<0.001), or medical co-morbidity (p = 0.003). Adults with new onset MDD were younger than other groups, and more likely than those who have recovered to have borderline personality disorder and concurrent psychiatric or substance use disorders (p<0.05 for all).

CONCLUSION

Behavioral histories/experiences and multi-morbidities differ significantly across stages of MDD. These concurrent problems may impede recovery and foster chronicity and should therefore be an integral focus of treatment.

Social Isolation and Loneliness in Older Adults: Review and Commentary of a National Academies Report

The authors of this review both served on the National Academy of Science, Engineering, and Medicine Committee that produced the report, "Social Isolation and Loneliness in Older Adults: Opportunities for the Health Care System." In 2018, the AARP Foundation commissioned the National Academies to establish a committee to research and develop a report on social isolation and loneliness in persons 50 years of age and older. Emphasis was placed upon the role of the healthcare system in addressing this fundamental public health problem. The committee released the report in February 2020 as the Corona Virus Disease 2019 pandemic was beginning to spread to North America. In this review, the authors share central findings and conclusions from the report as well as how these findings may be relevant to the care and well-being of older adults during this historic pandemic. The health protective benefits of social distancing must be balanced by the essential need for sustaining social relationships.

The bidirectional relationship between loneliness and common mental disorders in adults: findings from a longitudinal population-based cohort study

PURPOSE

Limited longitudinal population-based research exists on the bidirectional association between loneliness and common mental disorders (CMDs). Using 3-year follow-up data, this study examined whether loneliness among adults increases the risk for onset and persistence of mild-moderate or severe CMD; and whether mild-moderate or severe CMD is a risk factor for onset and persistence of loneliness.

METHODS

Data were used from the second ('baseline') and third (3-year follow-up) waves of the Netherlands Mental Health Survey and Incidence Study-2, a prospective study of a representative cohort of adults aged 18-64 years. Twelve-month CMDs and their severity were assessed with the Composite International Diagnostic Interview 3.0, and current loneliness using the De Jong Gierveld Loneliness Scale. Multivariate analyses were controlled for several potential confounders.

RESULTS

Loneliness predicted onset of severe CMD at follow-up in adults without CMDs at baseline, and increased risk for persistent severe CMD at follow-up in those with CMD at baseline. Conversely, severe CMD predicted onset of loneliness at follow-up in non-lonely adults at baseline, but was not associated with persistent loneliness at follow-up in lonely adults at baseline. Observed associations remained significant after controlling for perceived social support at baseline, except for the relationship between loneliness and persistent severe CMD. No longitudinal relationships were observed between loneliness and mild-moderate CMD.

CONCLUSIONS

Attention should be paid to loneliness, both in adults with and without CMD. Further research is needed to better understand the mechanisms underlying the observed associations between loneliness and CMDs to develop successful interventions.

Development of an audio and computer cognitive behavioral therapy for depression in older adults

Background: The purpose of this paper is to discuss the development of two novel technology-based interventions for depression in older adults while comparing older adults' preferences for audio-based and computer-based cognitive behavioral therapy for depressive symptoms. The audio program consisted of eight compact discs and a workbook while the computer program consisted of 11 modules of similar duration provided on a tablet PC. Both interventions consisted of the following topics: 1) introduction, 2) identifying and changing unhelpful thoughts, 3) addressing feelings, 4) relaxation, 5) engaging in pleasant events, 6) assertiveness, and 7) problem-solving. Methods: Fifty-one older adults were recruited from medical settings and rural communities and randomly assigned to an immediate treatment group (computer or audio) with minimal contact or a four-week minimal contact delayed treatment control condition. Results: Participants rated computer-based and audio-based cognitive behavioral therapy fairly equally, with 75% of those who received audio treatment and 85% of those who received computer-based treatment indicating benefits to their mood.Discussion: Computer-based or audio-based cognitive behavioral treatments may be valuable, low-cost modalities to deliver psychotherapy to older adults with depressive symptoms within a health care setting. Both modalities seem to be accepted by older adults.

The role of metabolic syndrome in late-life depression over 6 years: The NESDO study

BACKGROUND

Metabolic syndrome (MetS) has been associated with both early- and late-life depression. This study investigated whether baseline MetS and its individual components are associated with the course of depression over six years among older persons with a formal depression diagnosis.

METHODS

Data were used from 378 older persons with a depressive disorder from the Netherlands Study of Depression in Old age (NESDO) with a 6-year follow-up. A formal depression diagnosis according to DSM-IV-TR criteria was ascertained with the Composite International Diagnostic Interview. Severity of depressive symptoms was assessed with the Inventory of Depressive Symptomatology at 6-month intervals. Metabolic syndrome (MetS) was defined according the modified National Cholesterol Education Programme - Adult Treatment Panel III criteria. Primary outcome was time to remission from depression. We applied cox regression analysis for the primary outcome and linear mixed models for secondary analyses.

RESULTS

Neither MetS nor its individual components were associated with time to remission from depression (MetS: HR = 1.03; 95% CI = 0.74 - 1.44; p = 0.85), or with depression severity (MetS: B = 0.02; SE = 0.04; p = 0.64) and course of depressive symptoms (MetS: B = -0.01; SE = 0.01; p = 0.23) over 6-years follow-up.

LIMITATIONS

Attrition was relatively high (46.8%). Furthermore, we only had information on formal depression diagnosis at baseline, 2-year, and 6-year follow-up.

CONCLUSIONS

We found no evidence for an effect of baseline presence of metabolic dysregulation on the course of formally diagnosed depression in older persons. Metabolic syndrome in depressed patients should be clinically monitored for other reasons than predicting chronicity or severity of depression.

Emotional stability is associated with the MAOA promoter uVNTR polymorphism in women

BACKGROUND

Neuroticism is associated with low emotional stability, and it is characterized by a tendency to perceive ordinary situations as threatening and difficult to manage. This personality trait has been associated with psychological distress and predicts some mental disorders. Previous studies have shown that women tend to be more neurotic than men and, in general, females have also a higher incidence of anxious and depressive disorders.

METHODS

We analyzed in a sample of 99 female university students (from 18 to 26 years old) if emotional stability, measured using the Big Five Questionnaire, was linked to polymorphic variants in candidate genes related to dopaminergic and serotonergic systems, and other personality variables.

RESULTS

We found that emotional stability and its subdimensions are genetically associated with MAOA-uVNTR polymorphism. Thus, women carriers of the 3-repeat allele (lower MAO-A expression) showed higher levels of emotional stability. No associations were found with other polymorphisms analyzed, including COMT Val¹⁵⁸ Met, 5-HTTLPR, and DAT 3'UTR VNTR. Furthermore, our results showed a negative correlation between emotional stability and depression, state anxiety, and trait anxiety. In fact, MAOA-uVNTR and trait anxiety also explained emotional stability and its subdimensions. We also found that other genetic characteristic, phenylthiocarbamide tasting, explained impulsivity, specifically tasters controlled impulses better than nontasters.

CONCLUSION

Our results indicate that neuroticism might be regulated by MAOA and could be a common factor between different phenotypes, such as aggressive behaviors or personality disorders, observed in women with higher activity genotype who had been exposed to negative environments during childhood. This study could lead to a better understanding of the basis of emotional stability and could lead to future projects for this purpose.

Conceptual framework for social connectedness in mental disorders: Systematic review and narrative synthesis

BACKGROUND

Adults with mental disorders are at a high risk of loneliness. Loneliness has been implicated in a wide variety of physical and mental health problems. Social connectedness interventions are one means to tackle loneliness but have shown mixed effectiveness. This study aims to: (1) identify existing measures of social connectedness and (2) develop a conceptual framework of social connectedness to inform future measurement and the development of new interventions.

METHODS

A systematic review of studies from six bibliographic databases was conducted. Studies were included if a quantitative measure of social connectedness was used amongst samples of adults with a mental disorder. Two analyses were conducted: a best evidence synthesis of measurement properties for identified measures and a narrative synthesis of items from these measures.

RESULTS

Twenty-eight papers were included, employing 21 different measures. Measurement properties were of poor or unknown quality. Data synthesis identified a five-dimension conceptual framework of social connectedness: Closeness, Identity and common bond, Valued relationships, Involvement and Cared for and accepted (giving the acronym CIVIC).

LIMITATIONS

The majority of studies were conducted in high-income countries. It was not possible to validate the conceptual framework using the identified psychometric data.

CONCLUSIONS

The new five-dimension framework of social connectedness in mental disorders provides the theoretical foundation for developing new measures and interventions for social connectedness.

Reliability of retrospective reports on childhood abuse and its determinants in older adults during a 6-year follow-up

Controversy exists concerning the reliability of retrospective self-reports on childhood abuse since this method might be subject to under- or overreporting. Until now, no studies have been done in older adults, although reasons for under- or overreporting could be even more prominent in this age group. In this first study in older adults, test-retest reliability of retrospective measurements on childhood abuse and the influence of age, cognitive functioning and depression on this test-retest reliability was investigated. A longitudinal cohort study, the Netherlands Study of Depression in Older persons (NESDO), obtained information on childhood abuse at baseline and at a 6-year follow-up interview. Our sample consisted of 277 adults (mean age 68.5 years at baseline) of which 118 (42.6%) reported childhood abuse at baseline. The largest proportion of the answers was consistent (yes-yes or no-no) for every type of childhood abuse, varying from 85.2 to 93.5%. Looking more closely, 'yes' answers were more fluctuating than 'no' answers. Sexual abuse was most reliably reported in two separate interviews. There was no significant effect of age nor cognition on the test-retest reliability. Only test-retest reliability of emotional neglect was significantly associated with depression diagnosis and depression severity at baseline. In conclusion, test-retest reliability of retrospective self-reports on childhood abuse seems moderate to good, but slightly dependent on the type of abuse. The test-retest reliability was influenced neither by age nor cognition, only reporting of emotional neglect was associated with depression state.
