Subjective and objective assessments are associated for physical function but not cognitive function in community-dwelling stroke survivors

Experiences With Mobile Health-Enabled Ambulatory Monitoring Among Stroke Survivors: A Qualitative Study

Inquiring into the experiences of stroke survivors toward ambulatory monitoring is crucial for optimizing user adoption, design, implementation, and sustainability of ambulatory monitoring in the stroke population. This study was aimed to identify facilitators and barriers for ambulatory monitoring among stroke survivors, as well as their suggestions for development and implementation of ambulatory monitoring. We conducted individual semi-structured interviews with 40 stroke survivors who received ambulatory monitoring. The interviews were analyzed using thematic content analysis. Six themes about facilitators associated with ambulatory monitoring emerged: (1) user support, (2) technological features, (3) convenience, (4) personal strategies, (5)social influence, and (6)time commitment. Three themes about barriers to using ambulatory monitoring emerged: (1) personal factors, (2) functionality, (3) study design. Three themes about suggestions emerged: (1) personalization, (2) functionality, and (3) interactive feedback. As mobile health technology is becoming more popular, the findings of this study provide timely implications and practical considerations for ambulatory monitoring in the stroke population.

Feasibility of Telephone-Based Cognitive Assessments and Healthcare Utilization in US Medicare-Enrolled Older Adults Following Emergency Department Discharge

BACKGROUND

Wider screening and assessment for Alzheimer's disease and other related dementias (ADRD) may increase access to supportive care, improve allocation of medical care, and foster the use of interventions that prevent or delay disease progression. Yet, the effect of diagnostic timing on clinical and utilization outcomes is poorly understood. Community-based settings such as a hospital emergency department (ED) may be an underrecognized opportunity to assess cognition and impacts on individuals and health systems. This study assessed the feasibility of recruiting older adults for telephone-based trials following presentation to the ED and administering telephone based cognitive assessments over the phone in this population.

METHODS

Medicare-enrolled individuals 65+ years of age (n = 160) presenting to the Oregon Health & Science University Emergency Department (Portland, Oregon) between May 2022 and February 2023 were recruited by telephone. Participants were administered the Telephone Interview for Cognitive Status (TICS) Assessment and the Patient Reported Outcomes Measurement Information System (PROMIS) Cognitive Measure Questions on Mental Clarity via telephone 1-12 weeks post-discharge to evaluate cognition. Electronic medical records (EMR) were reviewed for medical care utilization including primary care provider (PCP) visits, hospital admissions, and ED visits for the 3 years prior to ED presentation.

RESULTS

Twenty-six percent of eligible ED users contacted elected for study enrollment. The TICS Assessment score had a significant relationship with the three evaluated health care utilization measures (ED, PCP visits, or hospitalizations); the PROMIS Assessment had significant but weak correlations to ED and PCP visits.

CONCLUSIONS

Older adults 65+ years presenting to the ED are amenable to enroll in telephone-based cognition-focused trials and cognitive assessments can be carried out over the telephone in this population. The PROMIS Assessment may be a better cognition assessment tool when evaluating for cognition and care utilization in this population. In addition to the limits of the screening tools used in this study, a lack of a representative sample is a limitation of the study design. Future studies could use other validated cognitive assessment tools and utilize a study design with a recruitment strategy focused on obtaining a representative sample of older ED patients.

Understanding task "challenge" in stroke rehabilitation: an interdisciplinary concept analysis

PURPOSE

Rehabilitation plays a critical role in minimising disability after stroke, with the concept of "challenge" proposed to be essential to rehabilitation efficacy and outcomes. This review unpacks how challenge is conceptualised in stroke rehabilitation literature from the perspectives of physiotherapy, occupational therapy, speech-language therapy and people with stroke. A secondary purpose was to provide a definition of challenge that is applicable to stroke rehabilitation.

METHODS

Principle-based concept analysis was utilised to examine challenge within the stroke rehabilitation literature. Forty-two papers were included. Data analysis involved immersion, analytical questioning, coding and synthesis to elicit the conceptual components of challenge.

RESULTS

Challenge was understood as a multidimensional and dynamic concept with three facets: nominal, functional and perceived challenge. Functional and perceived challenge were integral to optimal challenge. Optimal challenge was central to enhancing the outcomes and experiences of people with stroke, in rehabilitation and everyday life.

CONCLUSIONS

Challenge is a key concept which, when carefully optimised to the person's ability and experience, may positively influence their learning, recovery and engagement after stroke. This review lays a conceptual foundation for better understanding, operationalisation and advancement of challenge, offering important implications for addressing the growing burden of stroke disability, through rehabilitation.

Distinct Constructs Underlie Patient-Reported and Performance-Rated Outcomes after Stroke

OBJECTIVE

Patient-reported outcome measures (PROMs), which capture patients' perspectives on the consequences of health and disease, are widely used in neurological care and research. However, it is unclear how PROMs relate to performance-rated impairments. Sociodemographic factors are known to affect PROMs. Direct damage to brain regions critical for self-awareness (i.e., parietal regions and the salience/ventral-attention network) may also impair self-report outcomes. This study examined the relationship between PROMs and performance-based measures in stroke survivors with arm motor impairments. We hypothesized that PROMs would be distinct from performance-based outcomes, influenced by sociodemographic factors, and linked to damage in brain circuits involved in self-perception.

METHODS

We longitudinally assessed 54 stroke survivors using patient-reported and performance-rated measures at 4 timepoints. We used factor analysis to reveal the outcome battery's factorial structure. Linear regression examined the association between classes of measures and sociodemographics. Voxel-lesion-symptom-mapping, region-of-interest-based analysis, and voxel-lesion-network-mapping investigated the relationship between classes of outcomes and stroke-related injury.

RESULTS

Performance-based and patient-reported measures formed distinct factors, consistent across recovery phases. Higher education (β1 = 0.36, p = 0.02) and income adequacy (β2 = 0.48, p = 0.05) were associated with patient-reported, but not performance-rated outcomes. Greater parietal lobe injury, irrespective of hemisphere, was associated with worse patient-reported outcomes; greater corticospinal tract injury related to worse performance-rated outcomes. Lesions with greater functional connectivity to the salience/ventral-attention network were associated with worse patient-reported outcomes (r = -0.35, p = 0.009).

INTERPRETATION

Our findings reveal important differences between performance-rated and patient-reported outcomes, each with specific associated factors and anatomy post-stroke. Incorporating sociodemographic and neuroanatomic characteristics into neurorehabilitation strategies may inform and optimize patient outcomes. ANN NEUROL 2025;97:242-253.

Mental Health Mediators for Subjective, Not Objective, Cognition, and Community Participation Poststroke

Previous studies have stated that both objective and subjective cognitive abilities and mental health symptoms are associated with community participation poststroke. However, there is a need to understand the direct and indirect associations among these variables in persons with stroke. The objective of this study was to investigate whether mental health symptoms mediate the associations of subjective and objective cognitive abilities with community participation poststroke. We built regression-based mediation models with 74 participants with mild to moderate stroke. Independent variables were objective and subjective cognitive abilities. The dependent variable was community participation. Mediators were mental health symptoms including depression, apathy, and anxiety. The results indicated that depression (b = .093), apathy (b = .134), and anxiety (b = .116) fully mediated the association between subjective cognitive ability (p < .05), but not objective cognitive ability (p > .05), and community participation poststroke. Our findings suggest that poor subjective cognitive ability combined with mental health symptoms should be addressed together to promote community participation poststroke.

Meaningful to whom? Minimal clinically important differences and the priorities of individuals living with dementia for everyday function

Alzheimer's disease and Alzheimer's disease related dementias (AD/ADRD) have a significant impact on an individual's functional cognitive abilities, highlighting the need to prioritize measures of function in evaluating minimally clinically important difference (MCID) thresholds in AD/ADRD research. Input directly from individuals living with AD/ADRD on measures of function are lacking in MCID discussions, including what it means to live with AD/ADRD and what type and degree of improvements are most meaningful across the disease continuum. Most measures for assessing function in AD/ADRD trials are largely focused on basic and instrumental activities of daily living (BADL, IADL), which lack aspects of everyday function that matter most to individuals living with AD/ADRD. Expanding outcome evaluation to other dimensions of everyday function and diversifying measurement approaches is essential for optimizing inclusion of personally meaningful aspects of everyday function prioritized by individuals living with AD/ADRD and improving detection of potentially more sensitive changes in functioning. This perspective outlines four directions to expand and integrate what matters most to individuals living with AD/ADRD into trial outcome evaluation, including (1) consideration of how what matters most to individuals living with AD/ADRD may change across the disease continuum from mild to advanced dementia, (2) identification and evaluation of goals around strengths-based domains such as social participation rather than solely emphasizing deficits and losses, (3) utilization of goal-attainment scaling to more specifically match individually-specific functional goals, and (4) strengthening the inclusion and use of self-report and performance-based measures of function and triangulating these measures with informant-report measures.

Highlights

Alzheimer's disease and Alzheimer's disease related dementias (AD/ADRD) have a significant impact on an individual' functional cognitive abilities, of which changes in these abilities are measured through detection of minimally clinically important difference (MCID) thresholds to determine the effectiveness of AD/ADRD clinical trials.Widely used measures for assessing MCID thresholds in AD/ADRD trials focus on basic and instrumental activities of daily living, presenting opportunities to expand measurement of MCID to account for other dimensions of everyday function that are prioritized by individuals living with AD/ADRD.To expand outcome evaluation and improve integration of aspects of functioning that matter most to people living with AD/ADRD, we identify opportunities to incorporate more diverse strategies via goal-attainment scaling, self-report, and performance-based measures as appropriate. We also highlight the importance of incorporating strengths-based domains such as social participation, moving beyond deficit-focused assessment of functioning.

Functional Cognition: Moving the Field Forward

The concept of functional cognition has been variously defined, but at its core relates to how cognitive and performance abilities are integrated and used in everyday life. Functional cognition is a fundamental element of occupational performance, and functional cognitive assessment and intervention are central to how occupational therapy can improve client outcomes. Attendees at a conference convened by the American Occupational Therapy Foundation identified areas where the construct of functional cognition required further clarification. This paper briefly reviews these issues setting the stage for further conceptual analysis. The paper also examines the practical challenges that must be addressed before functional cognitive assessment and intervention can be fully integrated into occupational therapy practitioners' professional practice. Potential routes to address these challenges are identified.

The Prognostic Test Accuracy of the Short and Standard Forms of the Montreal Cognitive Assessment

INTRODUCTION

Cognitive impairment is a critical concern in stroke care, and international guidelines recommend early cognitive screening. The aim of this study was to determine the prognostic accuracy of both the short and standard forms of the Montreal Cognitive Assessment (MoCA) in predicting long-term cognitive recovery following a stroke.

METHODS

For this study, we used data from the Efficacy of Fluoxetine - a Randomized Controlled Trial in Stroke (EFFECTS) study, which encompassed stroke patients from 35 Swedish centers over the period from 2014 to 2019. Cognitive assessments were initially conducted at 2-15 days post-stroke, with follow-up data gathered at 6 months. We used the MoCA for objective cognitive evaluation. For assessing subjective cognitive impairment, we used the memory and thinking domain of the Stroke Impact Scale. For psychometric evaluation of the short Swedish version of MoCA (s-MoCA-SWE), we used cross tables and binary logistic regression.

RESULTS

The study included 1,141 patients (62.2% men; median [interquartile range; IQR] age, 72.3 [13.2] years; median [IQR] stroke severity, 3.0 [3.0]). At baseline, the prevalence of cognitive impairment was 71.7% according to the s-MoCA-SWE (≤12) and 67.0% according to the MoCA (≤25). The s-MoCA-SWE demonstrated a sensitivity of 92.3% for correctly identifying patients with objective cognitive impairment and 81.5% for identifying those with subjective impairments at 6 months. Although the s-MoCA-SWE had higher sensitivity, the MoCA had a more balanced sensitivity and specificity in detecting both subjective and objective cognitive impairments. In both crude and multivariable models, the s-MoCA-SWE was more strongly associated than the MoCA with cognitive impairment at 6 months.

CONCLUSIONS

Both the short and standard versions of the MoCA appear to be effective in identifying individuals likely to experience persistent cognitive issues following a stroke. Considering the limited time available in an acute stroke unit, the short-form version may be more practical. Nevertheless, further prospective studies are required to validate these findings.

Inter-relationships of depression and insomnia symptoms with life satisfaction in stroke and stroke-free older adults: Findings from the Health and Retirement Study based on network analysis and propensity score matching

BACKGROUND

Depression and insomnia are common co-occurring psychiatric problems among older adults who have had strokes. Nevertheless, symptom-level relationships between these disorders remain unclear.

OBJECTIVES

In this study, we compared inter-relationships of depression and insomnia symptoms with life satisfaction among older stroke patients and stroke-free peers in the United States.

METHODS

The study included 1026 older adults with a history of stroke and 3074 matched controls. Data were derived from the US Health and Retirement Study. Depression, insomnia and life satisfaction were assessed. Propensity score matching was employed to identify demographically-similar groups of stroke patients and controls. Central and bridge symptoms were assessed using Expected influence (EI) and bridge EI, respectively.

RESULTS

The prevalence of depression in the stroke group (25.0 %) was higher than that of controls (14.3 %, P < 0.001). In stroke group, "Feeling depressed" (CESD1; EI: 5.80), "Feeling sad" (CESD7; EI: 4.67) and "Not enjoying life" (CESD6; EI: 4.51) were the most central symptoms, while "Feeling tired in the morning" (JSS4; BEI: 1.60), "Everything was an effort" (CESD2; BEI: 1.21) and "Waking up during the night" (JSS2; BEI: 0.98) were key bridge symptoms. In controls, the most central symptoms were "Lack of happiness" (CESD4; EI: 6.45), "Feeling depressed" (CESD1; EI: 6.17), and "Feeling sad" (CESD7; EI: 6.12). Furthermore, "Feeling tired in the morning" (JSS4; BEI: 1.93), "Everything was an effort" (CESD2; BEI: 1.30), and "Waking up too early" (JSS3; BEI: 1.12) were key bridge symptoms. Life satisfaction had the most direct associations with "Not enjoying life" (CESD6) and "Feeling lonely" (CESD5) in the two groups, respectively.

CONCLUSION

Older adults with stroke exhibited more severe depression and insomnia symptoms. Interventions targeting central and bridge symptoms may help to mitigate the co-occurrence of these symptoms.

Health system implementation of the PROMIS Cognitive Function Screener in the Medicare Annual Wellness Visit: framing as abilities versus concerns

BACKGROUND

Cognitive assessment is a required component of the Medicare Annual Wellness Visit (AWV). In this prospective study, we evaluated acceptability and usefulness of a patient-reported outcome measure (the PROMIS® Cognitive Function Screener, or PRO-CS) to screen for cognitive impairment during the AWV. We compared two versions of the PRO-CS: Abilities and Concerns.

METHODS

We developed PRO-CS Abilities and PRO-CS Concerns using items from the PROMIS Cognitive Function item banks. We partnered with a large health system in Pennsylvania to implement an electronic health record (EHR)-integrated version of the 4-item PRO-CS into their AWV workflow. PRO-CS Abilities was implemented in June 2022 and then replaced with PRO-CS Concerns in October 2022. We used EHR data to evaluate scores on Abilities versus Concerns and their association with patient characteristics. We gathered feedback from providers on experiences with the PRO-CS and conducted cognitive interviews with patients to evaluate their preferences for Abilities versus Concerns.

RESULTS

Between June 2022 and January 2023, 3,088 patients completed PRO-CS Abilities and 2,614 patients completed PRO-CS Concerns. Mean T-scores for Abilities (54.8) were slightly higher (indicating better cognition) than for Concerns (52.6). 10% of scores on Abilities and 13% of scores on Concerns indicated concern for cognitive impairment (T-score < 45). Both Abilities and Concerns were associated with clinical characteristics as hypothesized, with lower scores for patients with cognitive impairment diagnoses and those requiring assistance with instrumental activities of daily living. Abilities and Concerns had similar negative correlations with depression (r= -0.31 versus r= -0.33) and anxiety (r= -0.28 for both), while Abilities had a slightly stronger positive correlation with self-rated health (r = 0.34 versus r = 0.28). In interviews, providers commented that the PRO-CS could be useful to facilitate conversations about cognition, though several providers noted potential limitations of patient self-report. Feedback from patients indicated a preference for PRO-CS Concerns.

CONCLUSIONS

Our findings suggest potential utility of the PRO-CS for cognitive screening in the Medicare AWV. PRO-CS Abilities and Concerns had similar associations with patient clinical characteristics, but the Concerns version was more acceptable to patients.

Identifying and regulating emotions after acquired brain injury: the role of interoceptive sensibility

Introduction

Interoceptive deficits are associated with difficulties in identifying and regulating emotions. However, research on interoception after acquired brain injury (ABI) is scarce, and its relationship with emotional difficulties in this population is unknown. This study aimed to (1) examine differences in self-reported alexithymia, performance-based emotional awareness, emotion regulation, depression, and interoceptive sensibility between ABI and control individuals; and (2) analyze the role of adaptive interoceptive dimensions in these emotional processes after ABI.

Methods

Forty-three individuals with ABI and 42 matched control individuals completed the Multidimensional Assessment of Interoceptive Awareness-2, the Toronto Alexithymia Scale, the Levels of Emotional Awareness Scale, the Difficulties in Emotion Regulation Scale, and the Hospital Anxiety and Depression Scale.

Results

Compared to the control group, individuals with ABI showed reduced tendency to ignore unpleasant sensations increased severity of depressive symptoms, as well as tendencies to have greater difficulties in emotion regulation and lower emotional awareness. Additionally, interoceptive dimensions such as trusting, as well as not-distracting from and not-worrying about bodily sensations, played a relevant role in explaining lower alexithymia and difficulties in emotion regulation. Moreover, lower alexithymia and emotion dysregulation were related to less depressive symptoms. These relationships were invariant across ABI and control individuals.

Discussion

Although individuals with ABI may have different levels of emotional abilities compared to non-ABI individuals, the relationship patterns between interoceptive and emotional processes appear to be similar between the two groups. This study suggests the potential benefit of addressing both interoceptive and emotional difficulties in treatments targeting such prevalent sequelae of ABI as depressive symptoms.

Multimodal Ambulatory Monitoring of Daily Activity and Health-Related Symptoms in Community-Dwelling Survivors of Stroke: Feasibility, Acceptability, and Validity

OBJECTIVE

To examine the feasibility, acceptability, and validity of multimodal ambulatory monitoring, which combines accelerometry with ecological momentary assessment (EMA), to assess daily activity and health-related symptoms among survivors of stroke.

DESIGN

Prospective cohort study involving 7 days of ambulatory monitoring; participants completed 8 daily EMA surveys about daily activity and symptoms (mood, cognitive complaints, fatigue, pain) while wearing an accelerometer. Participants also completed retrospective assessments and an acceptability questionnaire.

SETTING

Community.

PARTICIPANTS

Forty survivors of stroke (N=40).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Feasibility was determined using attrition rate and compliance. Acceptability was reported using the acceptability questionnaire. Convergent and discriminant validity were determined by the correlations between ambulatory monitoring and retrospective self-reports. Criterion validity was determined by the concordance between accelerometer-measured and EMA-reported daily activity.

RESULTS

All participants completed the study (attrition rate=0%). EMA and accelerometer compliance were 93.6 % and 99.7%, respectively. Participants rated their experience with multimodal ambulatory monitoring positively. They were highly satisfied (mean, 4.8/5) and confident (mean, 4.7/5) in using ambulatory monitoring and preferred it over traditional retrospective assessments (mean, 4.7/5). Multimodal ambulatory monitoring estimates correlated with retrospective self-reports of the same and opposing constructs in the predicted directions (r=-0.66 to 0.72, P<.05). More intense accelerometer-measured physical activity was observed when participants reported doing more physically demanding activities and vice versa.

CONCLUSIONS

Findings support the feasibility, acceptability, and validity of multimodal ambulatory monitoring in survivors of mild stroke. Multimodal ambulatory monitoring has potential to provide a more complete understanding of survivors' daily activity in the context of everyday life.

Self-Perceived ADL/IADL Function is Influenced by Residual Neurological Impairment, Aphasia, and Anxiety

BACKGROUND.

Self-perceptions of performance of activities of daily living (ADL) and instrumental activities of daily living (IADL) are reduced following stroke. Research investigating contributing factors is lacking.

PURPOSE.

We examined the extent to which aphasia status, neurological impairment and poststroke depression, and anxiety contribute to self-perceived ADL/IADL function.

METHOD.

Seventy-six community-dwelling individuals at least 6 months poststroke, 44 with and 32 without aphasia, participated in the cross-sectional study. The Stroke Impact Scale (SIS) ADL/IADL domain was the primary outcome measure with aphasia status, residual neurological impairment, depressive symptoms, and anxiety as predictor variables.

FINDINGS

Aphasia status, residual neurological impairment, and anxiety were independent predictors of self-perceived ADL/IADL function, together accounting for more than half the variance. Depression was not associated with ADL/IADL.

IMPLICATIONS.

Clinician awareness of the influence of anxiety on self-perceived ADL/IADL function, particularly for people with aphasia, may lead to future interventions that improve self-perceived ADL/IADL function.

Evaluation of PROMIS Cognitive Function Scores and Correlates in a Clinical Sample of Older Adults

In this study we assessed the utility of self-reported cognitive function using two PROMIS® Cognitive Function (PROMIS-CF) items in an observational clinical sample of patients aged 65 and older (n = 16,249) at a large health system. We evaluated the association of PROMIS-CF scores with clinical characteristics and Montreal Cognitive Assessment (MoCA) scores, and we used logistic regression to examine predictors of 1-year decline in PROMIS-CF scores among patients with available data. PROMIS-CF scores were associated with clinical characteristics as hypothesized, with lower (more impaired) scores for patients with cognitive impairment (CI) diagnoses, multiple comorbidities, and those taking cognitive enhancing or interfering medications. PROMIS-CF scores were also positively associated with MoCA scores. Predictors of 1-year decline in PROMIS-CF scores included CI diagnoses, use of cognitive enhancing medications, higher depression scores, and lower social role function. Our findings suggest potential utility of PROMIS-CF items in a brief patient-administered screening tool for CI.
