Symptomatic and functional recovery in depression in later life

Risk prediction of functional disability among middle-aged and older adults with arthritis: A nationwide cross-sectional study using interpretable machine learning

BACKGROUND

Arthritis is a common chronic disease among middle-aged and older adults and is strongly related to functional decline.

METHODS

The research sample and data were derived from the China Health and Retirement Longitudinal Study (CHARLS) 2015. We employed the least absolute shrinkage and selection operator (LASSO) and multifactor logistic regression analysis to identify features for model construction. We proposed six machine learning (ML) predictive models. The optimal model was selected using various learning metrics and was further interpreted using the SHapley Additive exPlanations (SHAP) method.

RESULTS

A total of 5111 subjects were included in the analysis, of which 1955 developed functional disability. Among the six models, XGBoost showed the best performance, achieving a test set area under the curve (AUC) of 0.74. SHAP analysis ranked the features by their contribution as follows: waist circumference, handgrip strength, self-reported health status, age, body pains, depression, history of falls, sleeping duration, and availability of care resources. SHAP dependence plots indicated that individuals over 60 with increased waist circumference (>85 cm), short sleeping duration (<5 h), and lower handgrip strength (<25 kg) had a higher probability of functional disability.

CONCLUSION

This study presents an interpretable machine learning-based model for the early detection of functional disability in patients with arthritis and informs the development of care strategies aimed at delaying functional disability in this population.

Association Between Personality Traits and Functional Limitations in Older Adults with Affective Disorders: A Cross Sectional Study

OBJECTIVES

Personality traits and affective disorders are both related to functional limitations. It is unknown whether personality traits have an additional effect on functioning in older adults with affective disorders. We studied the association between personality traits and functioning within this group.

METHODS

We performed a cross-sectional study of 180 older patients referred to outpatient specialized geriatric mental health care centers with a depressive, anxiety and/or somatic symptom disorder according to DSM-criteria. We studied the association between the Big Five personality traits and functional limitations assessed with the WHO-DAS II, adjusting for potential confounders, including the severity of various affective disorders.

RESULTS

The 180 patients (57.1% female, mean age 69.2 years) had an average WHO-DAS II score of 31.3 (SD 15.1). Lower scores on Conscientiousness were associated with more overall functional limitations (p = .001), particularly limitations in self-care (p = .001) and household activities (p = .001). Lower Extraversion scores were associated with more limitations in getting along with others (p = .001).

CONCLUSIONS

Personality traits are related to functional limitations independent of the severity of affective disorders in older adults.

CLINICAL IMPLICATIONS

Personality traits may be used as predictive factors for functioning in older adults with affective disorders.

Functioning in patients with major depressive disorder in remission: A systematic review and meta-analysis

BACKGROUND

Major depressive disorder (MDD) is one of the leading causes of burden of disease globally. We aimed to investigate whether global functioning is impaired in patients with MDD in full or partial remission compared to healthy control individuals (HC).

METHODS

We conducted a systematic review and meta-analysis according to the PRISMA guideline. We searched the databases PubMed, EMBASE and PsycINFO from January 1st 1980 to February 1st 2023. We included studies of adults with a diagnosis/former diagnosis of MDD with assessment of global functioning performed during a state of full or partial remission. The methodological quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Checklist. Standardised mean differences (SMD) using random-effects models were calculated as the summary measure. We further performed meta-analyses of the mean raw score in patients with MDD for individual functioning scales.

RESULTS

Forty-two studies, comprising 17,999 patients with MDD and 35,550 HC, were included, 14 of which included both patients with MDD in full or partial remission and HC. Global functioning was lower in patients with MDD in full or partial remission compared with HC (SMD -2.00, 95 % CI: -0.9 to -3.03, 15 comparisons, I2: 99.8 %).

LIMITATIONS

Important information about the study participants and setting was not reported for most studies, or the reporting was unclear.

CONCLUSION

Patients with MDD have lower levels of functioning compared with HC also when in full or partial remission. Assessment of functioning should be an essential component of managing patients with MDD, also during remission.

Functional improvement by behavioural activation for depressed older adults

BACKGROUND

Recovery in mental health care comprises more than symptomatic improvement, but preliminary evidence suggests that only collaborative care may improve functioning of depressed older adults. This study therefore evaluates the effectiveness of behavioural activation (BA) on functional limitations in depressed older adults in primary care.

METHODS

This study uses data from a multicentre cluster randomised controlled trial in which 59 primary care centres (PCCs) were randomised to BA and treatment as usual (TAU), and 161 consenting older (≥65 years) adults with clinically relevant symptoms of depression participated. Interventions were an eight-week individual BA programme by a mental health nurse (MHN) and unrestricted TAU. The outcome was self-reported functional limitations (WHODAS 2.0) at post-treatment (9 weeks) and at 12-month follow-up.

RESULTS

At the end of treatment, the BA participants reported significantly fewer functional limitations than TAU participants (WHODAS 2.0 difference -3.62, p = 0.01, between-group effect size = 0.39; 95% CI = 0.09-0.69). This medium effect size decreases during follow-up resulting in a small and non-significant effect at the 12-month follow-up (WHODAS 2.0 difference = -2.22, p = 0.14, between-group effect size = 0.24; 95% CI = -0.08-0.56). MoCA score moderated these results, indicating that the between-group differences were merely driven by those with no cognitive impairment.

CONCLUSIONS

Compared to TAU, BA leads to a faster improvement of functional limitations in depressed older adults with no signs of cognitive decline. Replication of these findings in confirmatory research is needed.

Effectiveness of late-life depression interventions on functional limitations: A systematic review

Depression is one of the most prevalent mental disorders in older adults and leads to considerable decreases in health, well-being, and impaired functioning. Intervention studies have focused on the effects on symptomatic recovery, and most do not include functional recovery as an outcome. Reduction of functional limitations as a treatment goal in old-age psychiatry aligns with the values of older persons. The objective of this review was therefore to evaluate the effectiveness of late-life depression interventions on functional limitations. This systematic review identified 15 randomized controlled trials in which the effectiveness of different interventions on functional limitations was evaluated in patients with late-life depression. The interventions were categorized into four categories: psychological interventions, drug treatment, physical exercise, and collaborative care. Multicomponent and collaborative-care interventions appear to be the most promising for improvement of functional limitations, particularly in primary care and community-dwelling populations of older persons with symptoms of depression. There is, however, a lack of evidence regarding studies in specialized mental health care.

One-year follow-up of functional impairment in inpatients with mood and anxiety disorders - Potentials of the Mini-ICF-APP

BACKGROUND

The aim of the study was to investigate functional impairment and its relationship to illness severity in a sample of patients with a diagnosis of mood or anxiety disorder during inpatient treatment and 1 year after discharge.

METHODS

Two hundred thirty-nine inpatients with primary diagnoses of mood or anxiety disorders were assessed at baseline and at follow-up by a range of validated instruments. Mini-ICF-APP was used for the assessment of functional impairment, BDI-II for the assessment of clinical symptoms and remission. Sample characteristics and measures of impairment at baseline and at follow-up were analysed descriptively. Symptomatically remitted and non-remitted patients were compared with regard to capacity limitations.

RESULTS

Initially, the sample showed considerable impairment in many capacities, particularly endurance, spontaneous activities, structuring of tasks, competency and flexibility. After 1 year, all capacities significantly improved. The level of impairment was correlated with employment status and severity of clinical symptoms. About 50% of the patients remitted in clinical symptomatology. Retrospectively, the remitted and the unremitted did not differ in functional impairment at baseline but there were considerable differences at follow-up.

CONCLUSIONS

Mini-ICF-APP is a useful instrument to monitor functional status and change in psychiatric samples, complementing the usual focus on symptom reduction.

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.

Clinical Neuropsychological Evaluation in Older Adults With Major Depressive Disorder

PURPOSE OF THE REVIEW

Older adults with major depressive disorder are particularly vulnerable to MDD-associated adverse cognitive effects including slowed processing speed, decreased attention, and executive dysfunction. The purpose of this review is to describe the approach to a clinical neuropsychological evaluation in older adults with MDD. Specifically, this review compares and contrasts neurocognitive screening and clinical neuropsychological evaluation procedures and details the multiple components of the clinical neuropsychological evaluation.

RECENT FINDINGS

Research has shown that neurocognitive screening serves a useful purpose to provide an acute and rapid assessment of global cognitive function; however, it has limited sensitivity and specificity. The clinical neuropsychological evaluation process is multifaceted and encompasses a review of available medical records, neurobehavioral status and diagnostic interview, comprehensive cognitive and clinical assessment, examination of inclusion and diversity factors as well as symptom and performance validity, and therapeutic feedback. As such, the evaluation provides invaluable information on multiple cognitive functions, establishes brain and behavior relationships, clarifies neuropsychiatric diagnoses, and can inform the etiology of cognitive impairment. Clinical neuropsychological evaluation plays a unique and critical role in integrated healthcare for older adults with MDD. Indeed, the evaluation can serve as a nexus to synthesize information across healthcare providers in order to maximize measurement-based care that can optimize personalized medicine and overall health outcomes.

Exploring Factors Associated with Functional Change and Predictors of Participation Improvement-A Two Years Follow-Up on People with Depression

The purpose of this study is to understand the functional status distribution and to explore the factors associated with changes in functional status and social participation in people with depression using two-year follow-up data. Subjects were selected from the Taiwan Databank of Persons with Disabilities (TDPD) if they had an evaluation date between July 2012 and 31 December 2017. We used data for 1138 individuals with multiple evaluation records and who were diagnosed with depression. The WHO Disability Assessment Schedule 2.0 (WHODAS 2.0) was the primary functional status measure. Other factors selected from the TDPD included social demographic data, living situation, employment status, economic status, and educational level. The results show scores in all dimensions of the WHODAS 2.0 declined over two years, especially in the domains of cognition, household activities, social participation, and total WHODAS 2.0 score. Aging groups showed poor recovery in cognition, getting along with others, and household activities. People living in suburban areas showed poorer recovery than people living in rural and urban areas in cognition, self-care, and general function (total score of WHODAS 2.0). Employment was also strongly associated with functional recovery in household activities, social participation, and general function. The original scores for cognition and getting along with others showed a significant negative relationship with social participation improvement. Our results can be used by policy makers to provide resources and conduct investigations, and by clinicians when making rehabilitation plans.

Association of the cumulative burden of late-life anxiety and depressive symptoms with functional impairment

OBJECTIVES

This study investigates the association of the cumulative burden of anxiety-only, depression-only, and comorbid anxiety and depression symptoms with (a) incident self-care or household activities impairment among those with no baseline self-care or household activities impairment, respectively, or (b) change in status of self-care or household activities impairment among those with baseline impairment.

METHODS

This study consists of participants (N = 4619) from the National Health and Aging Trends Study, a longitudinal study that examines a nationally representative sample of US adults aged 65 years and older. Outcomes included incident or change in self-care or household activity impairment. Primary independent variables were yearly counts of screening positive for clinically significant symptoms for anxiety-only, depression-only, or co-occurring anxiety and depression. Multivariable logistic regression models examined incident impairment and change in impairment status.

RESULTS

Yearly counts of anxiety-only symptoms were associated with incident impairment in self-care and household activities and less improvement in self-care functioning. Yearly counts of depression-only symptoms were associated with incident impairment in self-care and household activities. Yearly counts of co-occurring symptoms of anxiety and depression were associated with incident impairment in self-care and household activities, less improvement in self-care activities, and worsening impairment in household activities.

CONCLUSIONS

This study finds that the cumulative burden of co-occurring anxiety and depression symptoms is associated with incident impairment in functioning, persistent self-care impairment, and deterioration in household activity impairment. These findings emphasize the importance of managing late-life anxiety and depressive symptoms, which are treatable, frequently co-occur, and contribute to disability.

Trajectories and determinants of functional limitations in late-life depression: A 2-year prospective cohort study

Background:

In mental health research, functional recovery is increasingly valued as an important outcome in addition to symptomatic remission.

Methods:

Course types of functional limitations among depressed older patients and its relation with symptomatic remission were explored in a naturalistic cohort study (Netherlands Study of Depression in Older persons). 378 depressed older patients (≥60 years) and 132 non-depressed persons were included. Depressive disorders were assessed with Composite International Diagnostic Interview at baseline and two-year follow-up. Functional limitations were assessed every 6 months with the World Health Organization Disability Assessment II.

Results:

Depressed patients had more functional limitations compared to their non-depressed counterparts. Growth Mixture Modeling among depressed patients identified two trajectories of functional limitations, both starting at a high disability level. The largest subgroup (81.2%) was characterized by a course of high disability levels over time. The smaller subgroup (18.8%) had an improving course (functional recovery). After two years, the main predictor of functional recovery was the remission of depression. Among symptomatic remitted patients, female sex, higher level of education, higher gait speed, and less severe depression were associated with no functional recovery. Non-remitted patients without functional recovery were characterized by the presence of more chronic somatic diseases, a lower sense of mastery, and a higher level of anxiety.

Conclusions:

1 in 5 depressed older patients have a course with functional recovery. Combining functional and symptomatic recovery points to a subgroup of older patients that might profit from more rigorous psychiatric treatment targeted at psychiatric comorbidity and a group of frail depressed older patients that might profit from integrated geriatric rehabilitation.
