Apathy after stroke: Diagnosis, mechanisms, consequences, and treatment

Reliability, validity, and diagnostic accuracy of the apathy evaluation scale in chronic stroke survivors

BACKGROUND

We aimed to determine the psychometric properties of the Apathy Evaluation Scale (AES) in chronic stroke survivors.

METHODS

In this study, 112 non-cognitive impairment stroke survivors participated. Acceptability, inter-rater, and test-retest reliability of the three Persian versions of AES (clinician, informant, and self-rated) were evaluated. The correlation of three AES versions with the Hospital Anxiety and Depression Scale (HADS), Modified Rankin Scale (mRS), and Barthel Index (BI) was evaluated. To assess the diagnostic accuracy of the three AES versions, stroke survivors were classified as apathetic (n = 43) and non-apathetic (n = 69) groups using the 'diagnostic criteria of apathy'.

RESULTS

The floor and ceiling effect, skewness, and kurtosis were within acceptable range for three AES versions. Internal consistency (α = 0.88-0.91) and test-retest and inter-rater reliability (ICC2,1 >0.90) were acceptable for all AES versions. Standard Error of Measurement and Minimal Detectable Change values for test-retest and/or inter-rater reliability ranged 1.6-2.5 and 4.42-6.93 for three versions of AES, respectively. Significant moderate to high correlation (r or ƿ = -0.34-0.69) was found between three AES versions and HADS-D, HADS-A, BI, and mRS. The cut-off point > 34 (sensitivity = 87.5%, specificity = 72.22%, and AUC = 0.80) was derived for discriminating apathetic from non-apathetic stroke survivors based on the AES- self-rated total score.

CONCLUSION

All three AES versions are reliable and valid screening tools to evaluate and characterize apathy in stroke survivors. The AES-self-rated had good discriminative validity for discriminating apathetic from non-apathetic subjects in non-cognitive impairment stroke survivors.

Relationship between apathy/post-stroke depression and gait training in patients with stroke

BACKGROUND

We examined the effect of gait training on apathy/post-stroke depression (PSD) in patients with walking disorders after stroke, and the effect of apathy/PSD on gait reacquisition in subacute stroke.

METHODS

Fifty-five participants with gait disorders after stroke underwent gait training for 6 weeks. Outcome measurements included Apathy Scale (AS), Center for Epidemiologic Studies Depression Scale (CES-D), Mini-Mental State Examination, Lower Extremity Function of Stroke Impairment Assessment Set, and Functional Independence Measure-TRANSFER and -WALK scores. These scores of the participants were divided into groups with or without apathy based on AS scores for statistical analysis.

RESULTS

Both groups showed significant differences in all outcomes after gait training. In addition, even if the participants had apathy at baseline, there were no significant differences in outcomes other than AS/CES-D between the two groups after gait training. Logistic regression analysis showed that only Mini-Mental State Examination and Lower Extremity Function of Stroke Impairment Assessment Set scores affected the reacquisition of independent walking (odds ratio: 1.332, P = 0.015; odds ratio: 1.364, P = 0.005, respectively). AS and CES-D scores had no effects on gait reacquisition.

CONCLUSION

Gait training may be beneficial for both physical impairment and psychiatric symptoms in patients with stroke and may prevent poor functional recovery caused by apathy and PSD. As opposed to previous studies that have shown a negative impact of apathy and PSD on functional recovery, our results suggest that apathy/PSD may not negatively affect functional recovery when gait training is conducted in subacute stroke.

Advances in the study of apathy related to cerebral small vessel disease

Cerebral small vessel disease (CSVD) is a complex clinical-imaging pathological syndrome caused by small vessel lesions in the brain, which is characterized by aging-related, insidious onset and slow progression. Apathy is a key component of the common neuropsychiatric symptoms among CSVD patients, severely affecting their daily lives and social functioning. Moreover, there are fewer studies on CSVD-related apathy, and greater attention should be paid to this condition in clinical practice. This article describes the latest research advances in the concept, epidemiological features, pathogenesis, assessment and diagnosis, imaging and biomarkers, and treatment of CSVD-related apathy, aiming to serve as a reference for the clinical diagnosis and prevention of CSVD-related apathy.

Reward Decision Network Disconnection in Poststroke Apathy: A Prospective Multimodality Imaging Study

Apathy is a common neuropsychiatric symptom following stroke, characterized by reduced goal-directed behavior. The reward decision network (RDN), which plays a crucial role in regulating goal-directed behaviors, is closely associated with apathy. However, the relationship between poststroke apathy (PSA) and RDN dysfunction remains unclear due to apathy heterogeneity, the confounding effect of depression and individual variability in lesion impacts. This study aims to dissect the heterogeneity of PSA and explore the link between lesion-induced RDN damage and PSA. We prospectively recruited 207 patients with acute ischemic infarction and 60 demographically matched healthy controls. Participants underwent neuroimaging and longitudinal neuropsychiatric assessments. To characterize PSA heterogeneity, we employed multivariate analysis and clustering algorithms based on whole-brain functional connectivity and clinical assessments to classify patients into different PSA biotypes. We embedded each patient's lesion into a structural connectome atlas to obtain white matter (WM) disconnection maps. On this basis, WM disconnection scores were calculated for each brain region to quantify lesion-induced WM damage. We employed the XGBoost model to predict PSA biotypes based on WM disconnection scores, comparing the performance of models focusing on RDN-specific versus whole-brain WM disconnection. Additionally, we explored WM damage patterns across different biotypes by comparing disconnection scores in critical brain regions. We identified four PSA biotypes with unique clinical trajectories and neurobiological underpinnings. Biotype 4 was characterized by persistent apathy with depressive symptoms. Biotype 2 showed persistent apathy. Biotype 3 was non-apathetic. Biotype 1 exhibited delayed-onset apathy. The XGBoost models, when focused on the RDN-specific WM disconnection, performed significantly better in predicting PSA biotypes compared to the whole-brain WM disconnection model (t(164.66) = 8.871, p < 0.001). Analysis of WM disconnection patterns revealed that Biotype 4 exhibited more extensive RDN damage in crucial regions, Biotype 1 had a unique pattern of damage in the anterior cingulate cortex (t(61) = 1.874, p = 0.032), and Biotype 2 had a unique pattern of damage in the orbitofrontal cortex (t(53)= 1.827, p = 0.036). This study dissected PSA heterogeneity and demonstrated that RDN damage is a critical factor in PSA variability. We found that lesion-induced WM disconnections in anterior cingulate cortex and orbitofrontal cortex can lead to delayed-onset and persistent apathy, respectively. Furthermore, our findings revealed that apathy not only has distinct pathogenic mechanisms, but also shares neurobiological substrates with depression.

Using mechanistic knowledge to appraise contemporary approaches to the rehabilitation of upper limb function following stroke

It is a paradox of neurological rehabilitation that, in an era in which preclinical models have produced significant advances in our mechanistic understanding of neural plasticity, there is inadequate support for many therapies recommended for use in clinical practice. When the goal is to estimate the probability that a specific form of therapy will have a positive clinical effect, the integration of mechanistic knowledge (concerning 'the structure or way of working of the parts in a natural system') may improve the quality of inference. This is illustrated by analysis of three contemporary approaches to the rehabilitation of lateralized dysfunction affecting people living with stroke: constraint-induced movement therapy; mental practice; and mirror therapy. Damage to 'cross-road' regions of the structural (white matter) brain connectome generates deficits that span multiple domains (motor, language, attention and verbal/spatial memory). The structural integrity of these regions determines not only the initial functional status, but also the response to therapy. As structural disconnection constrains the recovery of functional capability, 'disconnectome' modelling provides a basis for personalized prognosis and precision rehabilitation. It is now feasible to refer a lesion delineated using a standard clinical scan to a (dis)connectivity atlas derived from the brains of other stroke survivors. As the individual disconnection pattern thus obtained suggests the functional domains most likely be compromised, a therapeutic regimen can be tailored accordingly. Stroke is a complex disorder that burdens individuals with distinct constellations of brain damage. Mechanistic knowledge is indispensable when seeking to ameliorate the behavioural impairments to which such damage gives rise.

Reinforcement Learning is Impaired in the Sub-acute Post-stroke Period

BACKGROUND

In humans, most spontaneous recovery from motor impairment after stroke occurs in the first 3 months. Studies in animal models show higher responsiveness to training over a similar time-period. Both phenomena are often attributed to a milieu of heightened plasticity, which may share some mechanistic overlap with plasticity associated with normal motor learning.

OBJECTIVE

Given that neurorehabilitation approaches are frequently predicated on motor learning principles, here we asked if the sensitivity of trial-to-trial learning for 2 kinds of motor learning processes often involved during rehabilitation is also enhanced early post-stroke. In a cross-sectional design, we compared (1) reinforcement and (2) error-based learning in 2 groups: 1 tested within 3 months after stroke (early group, N = 35) another tested more than 6 months after stroke (late group, N = 30). These 2 forms of motor learning were assessed with variations of the same visuomotor rotation task. Critically, motor execution was matched between the 2 groups.

RESULTS

Reinforcement learning was impaired in the early but not the late group, whereas error-based learning was unimpaired in either group. These findings could not be attributed to differences in baseline execution, cognitive impairment, gender, age, or lesion volume and location.

DISCUSSION

The presence of a deficit in reinforcement motor learning in the first 3 months after stroke has important implications for rehabilitation.

CONCLUSION

It might be necessary to either increase reinforcement feedback given early after stroke, increase the dose of rehabilitation to compensate, or delay onset of rehabilitation approaches that may rely on reinforcement, for example, constraint-induced movement therapy, and instead emphasize other forms of motor training in the subacute time period.

Associating Disrupted Intrinsic Functional Networks with Cognitive and Socio-Affective Skills Following Cerebellar Stroke

Stroke patients often experience post-stroke emotional impairments, yet the underlying pathophysiology remains unclear. At the brain level, dysregulation of socio-affective skills should be considered through alterations in brain networks instead of isolated regions. Investigating network alterations may be crucial in explaining emotional or cognitive deficits. In this context, and in line with the dysmetria of thought theory, cerebello-cortical networks' alterations could explain socio-affective functioning. To examine whether impairments in intrinsic functional networks following a cerebellar stroke are associated with poor cognitive and socio-affective performance. Thirty-six cerebellar stroke patients underwent resting-state functional MRI scans at the early stage (T1). They were assessed through a battery of clinical evaluations for cognitive and socio-affective skills. At the chronic stage (T2), evaluations were repeated with additional ecological momentary assessments (EMA) for emotional behavior. The global efficiencies of four resting-state functional brain networks associated with the cerebellum were determined. Patients were classified into subgroups of high and low functioning based on the evaluations and compared. Poorer global efficiency in the default-mode network was present in the subgroup with higher depression (T1: p = 0.034, T2: p = 0.006) and low EMA positive mood (p = 0.048), while lower efficiency in the dorsal attentional network was shown in the subgroup with lower verbal memory (T1: p = 0.004, T2: p = 0.048). Disruptions in intrinsic functional networks are linked to poorer cognition and emotion for some cerebellar stroke patients, partially supporting the theory of 'dysmetria of thought'.

A Biopsychosocial Framework for Apathy Following Moderate to Severe Traumatic Brain Injury: A Systematic Review and Meta-analysis

Apathy, the deficit of goal-directed behaviour, is well recognised as one of the most debilitating syndromes after moderate-to-severe traumatic brain injury (TBI). However, mechanisms underlying apathy, or at least factors associated with apathy, are sporadically reported. Based on a biopsychosocial framework, this systematic review and meta-analysis synthesised evidence regarding neurobiological, socio-environmental and individual factors associated with apathy. Our searches identified 21 studies satisfying inclusion and exclusion criteria. Results showed that the majority of work has focused on cognitive dysfunction, TBI-related factors, demographic variables and psychological correlates of apathy, while evidence for neural substrates and socio-cultural and premorbid aspects is scant. Overall, the current literature suggests that TBI-related and patient demographic factors did not contribute to apathy after TBI, whereas complex neurocognitive alterations, socio-environmental and cultural factors as well as patients' self-related factors may be important components. The evidence points to the multifaceted interplay of certain biopsychosocial contributors to apathy and suggests future investigations of more complex behavioural traits, cultural elements and pre-injury levels to better characterise the aetiology of this detrimental impairment after TBI.

Unraveling the Role of the Blood-Brain Barrier in the Pathophysiology of Depression: Recent Advances and Future Perspectives

Depression is a highly prevalent psychological disorder characterized by persistent dysphoria, psychomotor retardation, insomnia, anhedonia, suicidal ideation, and a remarkable decrease in overall well-being. Despite the prevalence of accessible antidepressant therapies, many individuals do not achieve substantial improvement. Understanding the multifactorial pathophysiology and the heterogeneous nature of the disorder could lead the way toward better outcomes. Recent findings have elucidated the substantial impact of compromised blood-brain barrier (BBB) integrity on the manifestation of depression. BBB functions as an indispensable defense mechanism, tightly overseeing the transport of molecules from the periphery to preserve the integrity of the brain parenchyma. The dysfunction of the BBB has been implicated in a multitude of neurological disorders, and its disruption and consequent brain alterations could potentially serve as important factors in the pathogenesis and progression of depression. In this review, we extensively examine the pathophysiological relevance of the BBB and delve into the specific modifications of its components that underlie the complexities of depression. A particular focus has been placed on examining the effects of peripheral inflammation on the BBB in depression and elucidating the intricate interactions between the gut, BBB, and brain. Furthermore, this review encompasses significant updates on the assessment of BBB integrity and permeability, providing a comprehensive overview of the topic. Finally, we outline the therapeutic relevance and strategies based on BBB in depression, including COVID-19-associated BBB disruption and neuropsychiatric implications. Understanding the comprehensive pathogenic cascade of depression is crucial for shaping the trajectory of future research endeavors.

Investigating the Prevalence and Predictors of Apathy among the Canadian Long-Term Care Residents: A Secondary Data Analysis

BACKGROUND

In long-term care facilities (LTCF), apathy is a prevalent issue, leading to cognitive decline, functional impairment, and increased mortality risk. Despite its significance, apathy often remains underrecognized and undermanaged in these settings. Recognizing and addressing the predictors of apathy is critical for early intervention and improved care outcomes.

PURPOSE

This study aims to assess the prevalence of apathy and identify its associated risk factors among newly admitted residents in the Canadian LTCF, using the InterRAI Minimum Data Set (MDS 2.0).

METHODS

We conducted a cross-sectional analysis of MDS 2.0 admission assessment data between 2015 and 2019, covering 157,596 residents across six Canadian provinces and one territory. Apathy was measured using the Apathy Index of the MDS 2.0, with the biopsychosocial model guiding the analysis.

RESULTS

The prevalence of apathy was 12.5% (19,758 individuals). The most significant predictors include cognitive impairments, specific age groups, hearing impairments, vision impairments, facility size and location.

CONCLUSIONS

The findings of this study underscore the need for tailored strategies in LTCF to address apathy, considering individual, institutional, and regional variations. Emphasis on environmental and personal factors is crucial in the management and prevention of apathy in these settings.

How do apathetic and depressive symptoms relate to functional capacity? A cross-sectional survey among community-dwelling middle-aged and older adults in Japan

BACKGROUND

Apathetic and depressive symptoms are frequently observed among older adults, and are risk factors for functional decline and dementia progression. However, how these symptoms influence functional capacity remains unclear. This study investigated the relationship between apathetic and depressive symptoms and functional capacity, considering the interaction between apathetic and depressive symptoms.

METHODS

A cross-sectional questionnaire survey targeting community dwelling middle-aged or older adults was conducted. We sent a questionnaire to 984 individuals and received 320 responses. Data with missing values and participants aged under 50 were excluded, resulting in 212 participants (88 men and 124 women, mean age = 73.4 ± 9.3 years). Apathetic symptoms were evaluated using the Dimensional Apathy Scale (J-DAS), which comprises executive, emotional, and cognitive and behavioral initiation aspects of apathy. Depressive symptoms were evaluated using the Geriatric Depression Scale (GDS). Functional capacity was assessed using the Japan Science and Technology Agency Index of Competence, which comprises technology usage, information practice, life management, and social engagement.

RESULTS

Mean score of each J-DAS factor and GDS was 5.3 ± 3.4 (executive), 12.0 ± 3.0 (emotional), 11.8 ± 5.1 (initiation), and 4.5 ± 3.3, respectively. The emotional and initiation aspects of J-DAS were significantly associated with information practice (β = -0.15, p < .05 for emotional; β = -0.27, p < .001 for initiation) and life management (β = -0.20, p < .01 for emotional; β = -0.22, p < .01 for initiation) in functional capacity. GDS was associated only with social engagement (β = -0.31, p < .001). Although the interaction between the initiation factor of J-DAS and GDS was significantly associated with life management (β = -0.16, p < .05), the R2 change was insignificant. The emotional factor of J-DAS was associated with technology usage (β = -0.13, p < .05), although less strongly than age. The executive factor of J-DAS had insignificant associations with all aspects of functional capacity.

CONCLUSIONS

Apathetic and depressive symptoms are independently, rather than interactively, associated with different aspects of functional capacity. As older adults with apathetic or depressive symptoms might struggle to seek help from public health services, they should be targeted with active interventions from healthcare professionals.

A cross-sectional study of the impact of stigma on quality of life in hemiplegic stroke patients following suicide attempts in nursing homes

To analyze the factors affecting stigma and quality of life in hemiplegic stroke patients following suicide attempts in nursing homes and to provide a theoretical basis for developing interventions in clinical care. General demographic information, the Stigma Scale for Chronic Illness (SSCI), and the Quality of Life Scale (SF-36) were used to investigate 259 patients with hemiplegia after stroke following nursing home suicide from January to April 2024. Univariate statistical analyses were performed to assess the impact of potential determinants on quality of life. Multiple regression models and stratified analyses with smoothed curve fitting were used for further evaluation. Multiple regression modeling showed that the factors influencing the quality of life in hemiplegic stroke patients following suicide attempts in nursing homes were stigma, Age, marital status, education, type of occupation, monthly household income, and duration of illness. The level of quality of life before unadjusted variables was strongly associated with high school and college education (β = 11.9, 95% CI: 8.2-15.6; P < 0.001), (β = 13.1, 95% CI: 9.2 -16.9; P < 0.001). After adjusting for confounders such as marital status (Married, Unmarried), Age (< 30, 30-40, 40-50, > 50) (β = 8.1, 95% CI: 4 .6-11.6; P < 0.0001). (β = 9.5, 95% CI: 6.0-13.1;P < 0.0001), the results were not significantly different. Curve fitting revealed threshold nonlinear associations between intrinsic and extrinsic stigma and quality of life, with quality of life decreasing as stigma increased. Conclusion Stigma is negatively correlated with the level of quality of life in hemiplegic stroke patients following suicide attempts in nursing homes. Different demographic profiles moderated patients' quality of life levels, and effective psychological intervention strategies should be used to improve patients' quality of life.

Vascular cognitive impairment and dementia: Mechanisms, treatment, and future directions

Worldwide, around 50 million people live with dementia, and this number is projected to triple by 2050. It has been estimated that 20% of all dementia cases have a predominant cerebrovascular pathology, while perhaps another 20% of vascular diseases contribute to a mixed dementia picture. Therefore, the vascular contribution to dementia affects 20 million people currently and will increase markedly in the next few decades, particularly in lower- and middle-income countries.In this review, we discuss the mechanisms of vascular cognitive impairment (VCI) and review management. VCI refers to the spectrum of cerebrovascular pathologies that contribute to any degree of cognitive impairment, ranging from subjective cognitive decline, to mild cognitive impairment, to dementia. While acute cognitive decline occurring soon after a stroke is the most recognized form of VCI, chronic cerebrovascular disease, in particular cerebral small-vessel disease, can cause insidious cognitive decline in the absence of stroke. Moreover, cerebrovascular disease not only commonly co-occurs with Alzheimer's disease (AD) and increases the probability that AD pathology will result in clinical dementia, but may also contribute etiologically to the development of AD pathologies.Despite its enormous health and economic impact, VCI has been a neglected research area, with few adequately powered trials of therapies, resulting in few proven treatments. Current management of VCI emphasizes prevention and treatment of stroke and vascular risk factors, with most evidence for intensive hypertension control. Reperfusion therapies in acute stroke may attenuate the risk of VCI. Associated behavioral symptoms such as apathy and poststroke emotionalism are common. We also highlight novel treatment strategies that will hopefully lead to new disease course-modifying therapies. Finally, we highlight the importance of including cognitive endpoints in large cardiovascular prevention trials and the need for an increased research focus and funding for this important area.

Apathy mediates the association between age and cognition after stroke

PURPOSE

To examine if the association between age and post-stroke cognition is mediated by apathy.

METHODS

A cross-sectional investigation was carried out with 389 stroke survivors and informants. Data were collected through the Apathy Evaluation Scale (AES-C) and the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE). Bivariate analyses were conducted between the IQCODE total score and each of the demographic and clinical characteristics as well as apathy, while Baron and Kenny's 4-step approach was used to examine the mediating effect of apathy on the association between age and post-stroke cognition.

RESULTS

Participants were aged 64.3 years on average, with a mean IQCODE score of 97.6 (SD: 14.8) and a mean AES-C score of 41.3 (SD: 8.0). IQCODE scores were positively correlated with age (r = 0.32, p < 0.001) and apathy (r = 0.54, p < 0.001). Apathy contributed to 24% of the total effect of age on post-stroke cognition, exerting a significant mediating effect on the relationship between age and post-stroke cognition.

CONCLUSIONS

Apathy may have a significant impact on the cognitive health of stroke survivors. Therefore, the early identification of apathy symptoms could facilitate consideration of potential interventions, such as multisensory and cognitive stimulation, designed to improve cognitive outcomes in this population.

Lille Apathy Rating Scale-Patient Version in Stroke Survivors: Psychometric Properties and Diagnostic Accuracy

OBJECTIVES

This study evaluated the factorial structure, psychometric properties, and diagnostic accuracy of the Persian version of the Lille Apathy Rating Scale-Patient version (LARS-P) in stroke survivors.

PARTICIPANTS

This study comprised 105 stroke survivors and 41 healthy controls.

METHODS AND SETTING

Exploratory factor analysis was used to determine the factors of the LARS-P. The acceptability, reliability, and validity of the LARS-P were also assessed. Agreement between the LARS-P and the Lille Apathy Rating Scale-informed version (LARS-I) was evaluated using the Bland-Altman plot. The diagnostic accuracy of the LARS-P was determined by categorizing stroke survivors into apathetic and nonapathetic groups based on the "diagnostic criteria of apathy."

RESULTS

The exploratory factor analysis showed 3 factors (action initiation and social life; novelty and motivation; and emotional and self-awareness), explaining 67.35% of the variance. Cronbach's alpha was 0.85 for between-items and 0.74 for between-subscales. Intra-class correlation coefficient (ICC)2,1 was >0.88 for test-retest and inter-rater reliability. The LARS-P showed moderate to strong correlations with the LARS-I and Neuropsychiatric Inventory-Apathy subscale (r = 0.70-0.82). In addition, the LARS-P had significant moderate correlations with 2 subscales of the Hospital Anxiety and Depression Scale, modified Rankin Scale, Barthel Index, and Lawton Instrumental Activities of Daily Living (r or ƿ = 0.47-0.63). There was a 96.19% agreement between LARS-P and LARS-I. The identified cutoff point (>17) for LARS-P exhibited 77.14% sensitivity and 90% specificity in diagnosing apathetic and nonapathetic stroke survivors.

CONCLUSIONS AND IMPLICATIONS

The LARS-P exhibits acceptable psychometric properties in stroke survivors, presenting a promising instrument for assessing apathy through a multidimensional framework.

Nursing's Role in Psychosocial Health Management After a Stroke Event: A Scientific Statement From the American Heart Association

INTRODUCTION

Stroke can have profound psychosocial health implications. These constructs are often overlooked and undertreated yet can be as devastating as the physical, functional, and cognitive consequences after stroke.

AIM

This scientific statement aims to evaluate 5 important aspects of psychosocial health (depression, stress, anxiety, fatigue, and quality of life) after a stroke to provide a framework for related nursing care across the poststroke continuum.

METHODS

A narrative review of the literature published from 2018 to 2023 was conducted with databases such as PubMed/MEDLINE, ClinicalTrials.gov, PsychInfo/EBSCOHost, PsychArticles, CINHAL, and the Cochrane Library.

RESULTS

Findings reveal a gap in evidence-based nursing interventions for addressing poststroke psychosocial needs. Critical strategies for shaping therapeutic nursing care include enhanced screening with validated tools; educating stroke survivors, families, and staff on symptom recognition, prevention, and treatment; and ensuring appropriate pharmacological management and access to psychological and psychosocial interventions, including referrals to social services and other essential support systems. Care should be comprehensive and interdisciplinary. Nurse-led research can benefit from more inclusive inclusion, including individuals with recurrent strokes and preexisting psychosocial conditions, focusing on the impact of structural racism and care disparities and expanding evidence-based nursing interventions.

CONCLUSIONS

Although there is limited high-level evidence on the nursing care for patients with suboptimal psychosocial health after stroke, nurses have a crucial role in addressing these needs. Enhanced screening, assessment, supportive services, and education are vital to ensure that patients receive the necessary treatment and care.

Depressive symptoms profile and dementia risk after spontaneous intracerebral haemorrhage

INTRODUCTION

Depressive symptoms are commonly reported after spontaneous intracerebral haemorrhage (ICH) and frequently associated with cognitive decline. Using hierarchical clustering analysis (HCA), we aimed to identify different post-ICH depressive symptoms profiles and to evaluate their association with dementia risk.

METHODS

We included consecutive patients from the prospective Prognosis of Intracerebral Haemorrhage (PITCH) study who survived 6 months after the ICH. We performed HCA using depressive symptoms severity (assessed using the Montgomery-Åsberg Depression Rating Scale (MADRS)), along with the presence of apathy and anxiety (screened using Neuropsychiatric Inventory questionnaire). Baseline clinical/neuroimaging characteristics and risk of incident dementia were compared between different profiles using univariate and multivariable models.

RESULTS

Of 265 six-month ICH survivors, 221 (83%) underwent neuropsychiatric screening (mean age 65.5 years; 57% male). Using HCA, 3 profiles were identified: (1) without significant depressive symptoms (n = 152; median MADRS score = 2 [IQR 0-4]); (2) depressive symptoms with predominant apathy (n = 41; median MADRS score = 15 [IQR 5-20], 68% with apathy); (3) depressive symptoms profile with predominant anxiety (n = 28; median MADRS score = 17 [IQR 9-25]; 100% with anxiety). Compared to patients without depressive symptoms, patients with depressive symptoms and predominant apathy (but not those with predominant anxiety) were more likely to have cerebral atrophy (OR = 2.4, 95% CI = 1.4-4.2) and had significantly higher long-term new-onset dementia risk (adjusted hazard ratio = 2.2, 95% CI = 1.3-3.8).

CONCLUSION

Screening for apathy and anxiety on top of depressive symptoms might help identifying patients at risk for dementia. Future studies on treatment should account for different post-ICH depressive symptoms profiles that may impact on cognitive function.

Shared and distinct cortical morphometric alterations in five neuropsychiatric symptoms of Parkinson's disease

Neuropsychiatric symptoms (including anxiety, depression, apathy, impulse-compulsive behaviors and hallucinations) are among the most common non-motor features of Parkinson's disease. Whether these symptoms should be considered as a direct consequence of the pathophysiologic mechanisms of Parkinson's disease is controversial. Morphometric similarity network analysis and epicenter mapping approach were performed on T1-weighted images of 505 patients with Parkinson's disease and 167 age- and sex-matched healthy participants from Parkinson's Progression Markers Initiative database to reveal the commonalities and specificities of distinct neuropsychiatric symptoms. Abnormal cortical co-alteration pattern in patients with neuropsychiatric symptoms was in somatomotor, vision and frontoparietal regions, with epicenters in somatomotor regions. Apathy, impulse-compulsive behaviors and hallucinations shares structural abnormalities in somatomotor and vision regions, with epicenters in somatomotor regions. In contrast, the cortical abnormalities and epicenters of anxiety and depression were prominent in the default mode network regions. By embedding each symptom within their co-alteration space, we observed a cluster composed of apathy, impulse-compulsive behaviors and hallucinations, while anxiety and depression remained separate. Our findings indicate different structural mechanisms underlie the occurrence and progression of different neuropsychiatric symptoms. Based upon these results, we propose that apathy, impulse-compulsive behaviors and hallucinations are directly related to damage of motor circuit, while anxiety and depression may be the combination effects of primary pathophysiology of Parkinson's disease and psychosocial causes.

A New Perspective on Stroke Research: Unraveling the Role of Brain Oxygen Dynamics in Stroke Pathophysiology

Stroke, a leading cause of death and disability, often results from ischemic events that cut off the brain blood flow, leading to neuron death. Despite treatment advancements, survivors frequently endure lasting impairments. A key focus is the ischemic penumbra, the area around the stroke that could potentially recover with prompt oxygenation; yet its monitoring is complex. Recent progress in bioluminescence-based oxygen sensing, particularly through the Green enhanced Nano-lantern (GeNL), offers unprecedented views of oxygen fluctuations in vivo. Utilized in awake mice, GeNL has uncovered hypoxic pockets within the cerebral cortex, revealing the brain's oxygen environment as a dynamic landscape influenced by physiological states and behaviors like locomotion and wakefulness. These findings illuminate the complexity of oxygen dynamics and suggest the potential impact of hypoxic pockets on ischemic injury and recovery, challenging existing paradigms and highlighting the importance of microenvironmental oxygen control in stroke resilience. This review examines the implications of these novel findings for stroke research, emphasizing the criticality of understanding pre-existing oxygen dynamics for addressing brain ischemia. The presence of hypoxic pockets in non-stroke conditions indicates a more intricate hypoxic scenario in ischemic brains, suggesting strategies to alleviate hypoxia could lead to more effective treatments and rehabilitation. By bridging gaps in our knowledge, especially concerning microenvironmental changes post-stroke, and leveraging new technologies like GeNL, we can pave the way for therapeutic innovations that significantly enhance outcomes for stroke survivors, promising a future where an understanding of cerebral oxygenation dynamics profoundly informs stroke therapy.

Association of depressive symptom severity and suicidal ideation with health-related quality of life among stroke survivors, NHANES 2005-2018

Stroke, a critical health issue in the US, not only has physical repercussions but also potentially affects the health-related quality of life (HRQoL) through neuropsychiatric outcomes like depressive symptoms and suicidal thoughts. This study utilized a nationally representative sample of 1302 US stroke survivors (age ≥ 20) from the US National Health and Nutrition Examination Survey (2005-2018) to assessed relationships between QoL via the CDC HRQOL-4 and evaluated depressive symptoms and suicidal ideation using the Patient Health Questionnaire-9 (PHQ-9). Participants (mean age: 64.4; 56.0 % female) showed that 40.7 % had at least mild depressive symptoms, and 18.8 % exhibited major depressive symptoms. Suicidal ideation was reported by 8.1 %. After sociodemographic and health condition adjustments, mild and major depressive symptoms, along with suicidal ideation, were associated with poorer general health status and more physically and mentally unhealthy days and activity limitation days. A dose-response relationship between PHQ-9 scores and HRQoL outcomes was evident (All P for trend <0.001). Stroke survivors with suicidal ideation also experienced more physically and mentally unhealthy days and activity limitation days. Depressive symptoms and suicidal ideation are associated with reduced HRQoL among US stroke survivors, underscoring the importance of thorough neuropsychiatric evaluations and interventions to bolster stroke survivors' well-being.

A literature review of outcome and treatment options after acquired brain injury: Suggestions for adult offenders using knowledge from the general population

BACKGROUND

Acquired brain injury (ABI) is a major health problem, often with negative effects on behaviour and mental health as well as cognition. Prevalence of ABI is exceptionally high among offenders and increases their re-offending risk. Information on risk factors for ABI and its outcomes among offenders that could guide effective treatment for them is, nevertheless, scarce and dispersed. However, there is a more substantial literature about the general population that could inform work with brain-injured offenders, especially when selecting for samples or subgroups with similar relevant characteristics, such as lower socio-economic status (SES), pre-injury lower tested intelligence score (<85) and pre-injury mental health problems.

AIMS

To explore brain injury data from non-offender samples of otherwise similar socio-economic and mental health and ability characteristics to offenders then, first, to describe their untreated outcomes and, secondly, outcomes after frequently used interventions in these circumstances, noting factors associated with their effectiveness.

METHOD

Three databases were systematically searched for the years 2010-2022; first, using terms for brain injury or damage and cognitive (dys)function, mental health or quality of life. Second, in a separate search, we used these terms and terms for interventions and rehabilitation. In the second review, studies were selected for clear, distinguishable data on age, sex, SES and lifestyle factors to facilitate inferences for offenders. A narrative analytical approach was adopted for both reviews.

RESULTS

Samples with characteristics that are typical in offender groups, including lower SES, lower pre-injury intelligence quotient (<85), prior cognitive impairments and prior mental health problems, had poorer cognitive and behavioural outcomes following ABI than those without such additional problems, together with lower treatment adherence. With respect to treatment, adequate motivation and self-awareness were associated with better cognitive and behavioural outcomes than when these were low or absent, regardless of the outcome measured.

CONCLUSIONS

More complex pre-injury mental health problems and social disadvantages typical of offenders are associated with poorer post-brain injury recovery. This paper adds to practical knowledge by bringing together work that follows specific outcome trajectories. Overall, succesful ABI-interventions in the general population that aim at pre-injury difficulties comparable to those seen among offenders, show that personalising injury-specific treatments and taking account of these difficulties, maximised positive outcomes.

Care burden and the predictive role of spiritual well-being and religious coping: A cross sectional study among Iranian family caregivers of patients with stroke

Background and Aims

The burden of care after a stroke is gaining recognition as a significant healthcare issue. Factors like religion and spirituality, encompassing religious coping and spiritual health, prove to be influential in anticipating the challenges faced by caregivers. The present study aimed to determine the relationship between care burden, spiritual health, and religious coping among caregivers of stroke patients.

Methods

This cross-sectional research was conducted with the participation of 129 caregivers of stroke patients. The data was collected using the Ellison and Paloutzian spiritual well-being instruments, Pargament Religious Coping (RCOPE) brief version, and the Zarit burden interview (ZBI). Through a census, participants were recruited for the investigation. Data were analyzed using descriptive and inferential statistics (multivariate linear regression analysis).

Results

The study results indicate a strong and statistically significant relationship between the burden of caring and spiritual health (p < 0.001, β = 0.33). Furthermore, specific variables were identified as indicators of an increased burden of care, including positive religious coping (p = 0.04, β = 0.63), the familial relationship between the caregiver and patient, specifically as a child (p = 0.001, β = 29.26), and a sister (p < 0.001, β = 35.93).

Conclusion

It is advisable to consider adopting and implementing appropriate support measures for coping strategies rooted in religion and spirituality. So, it is recommended to enhance the provision of comprehensive support, including psychological and religious interventions. This can be achieved through the collaborative efforts of support groups comprising psychiatric nurses, psychiatrists, psychologists, and religious experts.

The relationship between rehabilitation motivation and upper limb motor function in stroke patients

Objective

Insufficient motivation among post-stroke survivors may be an important factor affecting their motor function recovery. This study seeks to investigate the relationship between motivation and functional recovery in stroke patients undergoing rehabilitation training.

Materials and methods

103 stroke patients with upper limb impairments were studied during their hospital stays. Assessments were done before and after rehabilitation training to measure motivation, emotional state, motor function, and independence in daily activities. Data analysis was conducted to examine the distribution of these factors among the participants. Pearson and Spearman correlation analyses were used to study the relationships between motivation, emotional state, and motor function. Patients were divided into high and low motivation groups based on the Rehabilitation Motivation Scale (RMS), and chi-square and rank-sum tests were used to compare functional differences before and after treatment among patients with varying levels of motivation.

Results

66 participants were found to have low motivation in the initial assessment of the RMS (64.08%). Consistency in motivation levels was observed among patients with high motivation (r = 0.648, P<0.001). Apathy was identified as the main factor affecting motivation in patients with low motivation (p = 0.027), while depression and anxiety were not significantly correlated. Motivation was strongly linked to improvements in upper limb motor function, daily living activities, and self-exercise duration (p < 0.001) for stroke patients undergoing rehabilitation. Post-training, there was a notable increase in motivation, motor function, and independence in daily activities (p < 0.001). Increased rehabilitation motivation was linked to better upper limb motor function and daily independence in patients, particularly those with low motivation. This correlation was significant for both the FMA-UE and FIM scores.

Discussion

Old patients with poor upper limb motor function often have low motivation, which hinders their recovery. Using strategies to boost motivation in stroke patients with impaired upper limb function could greatly improve their rehabilitation and motor skills. It is crucial to prioritize these intervention strategies.

Conclusion

Enhancing rehabilitation motivation in stroke patients with low motivation and upper limb motor impairments can foster the restoration of their functional capabilities.

Effectiveness of Problem-Solving Therapy in Improving Patient Mental Health, Function, Quality of Life, and Mortality Post-Stroke: A Systematic Review

Problem-solving therapy (PST) is a potential psychological intervention aimed at preventing and treating psychological issues in stroke patients, although its efficacy is not clearly established. This systematic review assessed the effectiveness of PST in improving mental health, functioning, quality of life, and mortality in this population. Six databases were searched for literature indexed through March 2024, including the Cochrane Library, PubMed, Scopus, CINAHL, NeuroBITE, and OTseeker. This review (CRD42023483757) followed the PRISMA guidelines and the Cochrane Library Handbook, utilizing the RoB 2 tool and GRADE system to assess the quality of the evidence. It included eight randomized controlled trials (RCTs) involving 1249 patients with stroke. Among them, five RCTs showed that PST might improve depression. Additionally, individual RCTs demonstrated the efficacy of PST in addressing patient anxiety, apathy, and coping. With respect to mental health, PST might affect patient quality of life and mortality. However, the results of four RCTs demonstrated no effect of PST on patient functioning. The quality of evidence for the outcomes ranged from very low to high. PST may improve mental health, quality of life, and mortality in patients with stroke.

A comprehensive overview of post-stroke depression treatment options

Nearly one-third of all stroke patients develop depression at any time after a stroke, and its presence is associated with unfavorable outcomes. This narrative review aims to provide a synopsis of possible pharmacological and non-pharmacological treatment modalities for post-stroke depression (PSD). Several studies have demonstrated the efficacy and safety of selective serotonin reuptake inhibitors in treating the symptoms of this clinical condition. The treatment of PSD has been recently enhanced by innovative approaches, such as cognitive-behavioral therapy, virtual reality, telehealth, repetitive transcranial magnetic stimulation, and non-conventional therapies, which might improve depression treatment in stroke survivors. Future high-quality randomized controlled trials are necessary to confirm this hypothesis.

Apathy in persons living with HIV disease: A systematic narrative review

BACKGROUND

Apathy was identified as a feature of HIV early in the epidemic; however, there are no systematic reviews of the diverse literature on the sociodemographic and clinical correlates of apathy in HIV disease.

METHODS

The current study adopted a hybrid systematic-narrative review methodology in which we used PRISMA guidelines to identify, summarize, and critique peer-reviewed, empirical studies of apathy in HIV disease in the era of combination antiretroviral therapy.

RESULTS

A total of 34 studies of apathy in persons living with HIV (PLWH) were identified. Findings across these studies showed that apathy was reliably related to the structure of grey and white matter pathways commonly implicated in apathy, poorer everyday functioning, education, and other neuropsychiatric symptoms (e.g., depression). Apathy was not reliably associated with age, sex, race/ethnicity, cognition, and clinical markers of HIV disease.

LIMITATIONS

The current review does not provide rigorous quantitative estimates of clinical correlates of apathy, and the exclusion criteria of non-English and non-peer reviewed publications introduces risk of bias and Type I error.

CONCLUSIONS

Apathy occurs at higher rates in PLWH and is linked to neuroanatomical differences, as well as negative outcomes for everyday functions, aspects of neurocognition, and neuropsychiatric symptoms. As such, apathy is an important component to consider in the clinical assessment, diagnosis, and management of neurocognitive disorders in PLWH. Future work is needed to replicate existing findings with larger sample sizes and longitudinal designs, examine apathy as a multi-dimensional construct, and develop evidence-based treatments for apathy in PLWH.

Network analysis of neuropsychiatric, cognitive, and functional complications of stroke: implications for novel treatment targets

AIM

Recovery from stroke is adversely affected by neuropsychiatric complications, cognitive impairment, and functional disability. Better knowledge of their mutual relationships is required to inform effective interventions. Network theory enables the conceptualization of symptoms and impairments as dynamic and mutually interacting systems. We aimed to identify interactions of poststroke complications using network analysis in diverse stroke samples.

METHODS

Data from 2185 patients were sourced from member studies of STROKOG (Stroke and Cognition Consortium), an international collaboration of stroke studies. Networks were generated for each cohort, whereby nodes represented neuropsychiatric symptoms, cognitive deficits, and disabilities on activities of daily living. Edges characterized associations between them. Centrality measures were used to identify hub items.

RESULTS

Across cohorts, a single network of interrelated poststroke complications emerged. Networks exhibited dissociable depression, apathy, fatigue, cognitive impairment, and functional disability modules. Worry was the most central symptom across cohorts, irrespective of the depression scale used. Items relating to activities of daily living were also highly central nodes. Follow-up analysis in two studies revealed that individuals who worried had more densely connected networks than those free of worry (CASPER [Cognition and Affect after Stroke: Prospective Evaluation of Risks] study: S = 9.72, P = 0.038; SSS [Sydney Stroke Study]: S = 13.56, P = 0.069).

CONCLUSION

Neuropsychiatric symptoms are highly interconnected with cognitive deficits and functional disabilities resulting from stroke. Given their central position and high level of connectedness, worry and activities of daily living have the potential to drive multimorbidity and mutual reinforcement between domains of poststroke complications. Targeting these factors early after stroke may have benefits that extend to other complications, leading to better stroke outcomes.

Apathy After Stroke: Incidence, Symptom Trajectory, and Impact on Quality of Life and Disability

BACKGROUND AND OBJECTIVES

Apathy is one of the most common symptoms following stroke and is often associated with worse functional outcome and poor quality of life (QoL). The trajectory of apathy symptoms has been previously described, and different trajectories have been identified. We determined group and individual changes in apathy symptomatology from the acute phase until 1 year after stroke. We also examined the association of apathy and depression with disability and QoL 1 year after stroke.

METHODS

We measured apathy in a cohort of ischemic stroke survivors at 4 time points from 0 to 12 months after stroke. The Apathy Evaluation Scale (AES) and Dimensional Apathy Scale (DAS) were administered at each time point. Where possible we obtained apathy measured from carers. Depression was assessed with the Geriatric Depression Scale (GDS). Disability and QoL were assessed with the modified Rankin Scale (mRS) and 36-Item Short Form Survey (SF-36). We examined the cross-sectional and individual trajectory of apathy symptoms in each dimension and looked at associations of apathy and depression soon after stroke with mRS and SF-36 at 1 year.

RESULTS

Of 200 participants enrolled, 165 completed apathy measures at 12 months. Patient-rated apathy scores increased in both tests at the group level (AES: χ2(3) = 9.86, p = 0.019; DAS: χ2(3) = 8.49, p = 0.037) and individual level (AES: β = 0.13, p = 0.002; DAS β = 0.13, p = 0.005; DAS: executive β = 0.08, p < 0.001). By contrast, carer-rated apathy did not significantly increase (AES: χ2(3) = 0.75, p = 0.862; DAS: χ2(3) = 2.45, p = 0.484). Apathy scores were associated with worse mRS and SF-36, although most associations were no longer significant when controlling for depression. GDS was associated with worse mRS and SF-36 after controlling for covariates and apathy (mRS: β = 0.08, p = 0.006; SF-36 Mental Component Summary: β = -1.53, p < 0.001; SF-36 Physical Component Summary: β = -0.57, p = 0.016).

DISCUSSION

Self-reported apathy progressively increases after stroke, especially in the executive dimension. Apathy is associated with worse QoL and greater disability, although some of these associations might be mediated by depression.

Predictive Factors of Apathy in Stroke Survivors During the Recovery Period

ABSTRACT

BACKGROUND: Apathy may be an important predictor of depression and significantly negatively affect the quality of life and functional recovery of stroke survivors. However, the evidence reflects the inconsistent findings of studies on the impact of individual-related variables on apathy in patients with stroke. OBJECTIVES: This study examines the relationships among stroke survivors' individual characteristics, background variables, disease-related variables, and apathy; furthermore, we identify predictors of apathy. METHODS: In this cross-sectional correlational study, the participants were recruited from a medical university hospital. Three measurement tools were used: individual and background variables, the modified Rankin Scale, and the Apathy Evaluation Scale. Hierarchical multiple regression analysis was used to identify the predictors of apathy. RESULTS: Participants included 100 stroke survivors with a mean age of 59.9 (12.1) years. The prevalence of apathy among stroke survivors was 27%. Stroke survivors' economic sources (β = 0.430, P = .001), perceived family support (β = -0.163, P = .048), and modified Rankin Scale (β = 0.283, P = .001) accounted for 43.7% of the variance in survivor apathy. CONCLUSION: The results of this study clarified which individual characteristics, background variables, and disease-related variables are key predictors of apathy in patients with stroke.

Development of a patient-centered transition program for stroke survivors and their informal caregivers, combining case-management and access to an online information platform: A user-centered design approach

Background

During the hospital-to-home transition, stroke survivors and their caregivers face a significant lack of support and information which impacts their psychosocial recovery. We aimed to co-design a program combining individual support by a trained case-manager (dedicated professional providing individual support) and an online information platform to address needs of stroke survivors and caregivers.

Methods

A two-step methodology was used. The first step followed a "user-centered design" approach during four workshops with stroke survivors, caregivers, and healthcare professionals to develop the platform and define the case-manager profile. The second step was a usability test of the platform following a Think Aloud method with patients and caregivers. The workshops and interviews were analyzed following a qualitative thematic analysis. The analysis of Think Aloud interviews was based on User Experience Honeycomb framework by Morville.

Results

Eight participants attended the workshops: two patients, two caregivers, three nurses, and a general practitioner. Activities, training, and skills of the case-manager were defined according to stroke survivors and caregivers needs. Name, graphics, navigation, and content of the platform were developed with the participants, a developer and a graphic designer. The usability of the platform was tested with 5 patients and 5 caregivers. The Think Aloud confirmed satisfaction with graphics and content but a need for improvement regarding the navigability. An update of the platform was conducted in order to answer the needs expressed by participants.

Conclusion

We developed, with a participatory approach, a patient-centered transition program, which will be evaluated in a randomized controlled trial.

Presence and Characteristics of Behavioral and Psychological Symptoms in Subacute Stroke Patients with Cognitive Impairment

This retrospective cross-sectional study is aimed at investigating the prevalence and characteristics of behavioral and psychological symptoms (BPS) in subacute stroke patients with cognitive impairment. The Neuropsychiatric Inventory-Questionnaire (NPI-Q) was used to assess BPS. A total of 358 consecutive patients with first-ever stroke admitted to rehabilitation wards and with Mini-Mental State Examination (MMSE) scores < 24 on admission were included. BPS was defined as a total NPI-Q Severity or Distress score ≥ 1. Differences between the severity and presence of BPS among patients with severe cognitive impairment (MMSE scores 0-17) and those with mild cognitive impairment (MMSE scores 18-23) were analyzed using the Mann-Whitney U test and chi-squared test, respectively. Eighty-one patients (mean (standard deviation) age, 73.5 (13.1) years) were enrolled for analysis. BPS were observed in 69.1% and 74.1% of patients when assessed with NPI-Q Severity and NPI-Q Distress, respectively. The most frequently observed BPS was apathy, followed by depression (approximately 44% and 40%, respectively). The severity and frequency of delusions, euphoria, apathy, and disinhibition were significantly higher in the severe cognitive impairment group than in the mild cognitive impairment group. However, the severity, distress, and frequency of depression were not dependent on the severity of cognitive impairment. The presence of BPS, especially apathy and depression, in subacute stroke patients with cognitive impairment is high. The severity and frequency of some BPS are higher in patients with severe cognitive impairment than in those with mild cognitive impairment. However, depression is highly prevalent among the patients regardless of the severity of cognitive impairment.

Prevalence of post-stroke cognitive impairment and associated risk factors in Chinese stroke survivors

BACKGROUND

Post-stroke cognitive impairment (PSCI) adversely affects survivors' recovery trajectory and overall health outcomes. This study aimed to investigate the prevalence of PCSI and its associated risk factors.

METHODS

A cross-sectional study was conducted with stroke survivors recruited from the neurology units of three hospitals in Yunnan, China. Measures included the Frenchay Aphasia Screening Test (FAST), Apathy Evaluation Scale (AES), Fatigue Severity Scale (FSS), Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE), Montreal Cognitive Assessment (MoCA), and Charlson Comorbidity Index (CCI). Logistic regression analysis was carried out to identify risk factors significantly and independently associated with PSCI.

RESULTS

Of 389 stroke participants studied, 139 (36%) were found to have PSCI. Every 10-year increase in age [odds ratio (OR) =1.69, 95% confidence interval (CI): 1.27-2.24, p < 0.001], and 1-point increase in the AES (OR = 1.13, 95% CI: 1.07-1.18, p < 0.001) and FSS scores (OR = 1.06, 95% CI: 1.03-1.10, p < 0.001) were significantly associated with higher odds of PSCI. Conversely, a 1-point increase in the MoCA score (OR = 0.91, 95% CI: 0.87-0.95, p < 0.001) and having an undergraduate education (OR = 0.45, 95% CI: 0.24-0.84, p = 0.013) or postgraduate education (OR = 0.18, 95% CI: 0.06-0.50, p = 0.001) were associated with reduced odds of PSCI.

CONCLUSIONS

PSCI is prevalent in the Chinese population, with advanced age, lower education levels, lower MoCA scores, and higher fatigue and apathy scores identified as strong risk factors. It is recommended that psychological and cognitive assessment be routinely incorporated into post-stroke rehabilitation pathways to mitigate cognitive decline.

Effect of "Internet + tertiary hospital-primary hospital-family linkage home care" model on self-care ability and quality of life of discharged stroke patients

OBJECTIVE

To investigate the intervention effect of an "Internet + tertiary hospital-primary hospital-family linkage home care" model on the quality of life and self-care abilities of discharged stroke patients.

METHODS

The clinical data of 90 patients with stroke who were hospitalized and discharged from the Department of Neurology of the Affiliated Hospital of Youjiang Medical College for Nationalities from October 2020 to September 2021 were retrospectively analyzed. They were split into a control group (41 cases) and an intervention group (40 cases) based on different care modes. The intervention group was given the "Internet + tertiary hospital-primary hospital-family connection home care" paradigm, while the control group received normal nursing interventions. The degree of nerve defect, quality of life, anxiety and depression, self-care ability and exercise ability of the patients were evaluated by National Institutes of Health Stroke Scale (NIHSS), Stroke Specific Quality of Life Scale (SS-QOL), General Hospital Anxiety and Depression Scale (HADS), Self-care Ability Scale (ESCA), and Fugl-Meyer Motor Function Assessment (FMA) before discharge and at 3rd, 6th and 12th month after discharge, respectively. The re-hospitalization rate, treatment compliance and exercise ability of the two groups were compared within a year after discharge.

RESULTS

The scores of SS-QOL, ESCA and FMA in the intervention group increased with time, and the scores of SS-QOL, ESCA and FMA at 3rd, 6th and 12th month after discharge were higher than those in the control group (all P<0.05). The NIHSS and HADS scores decreased over time, and the NIHSS and HADS scores were lower than the control group at 12th month after discharge (P<0.05). Within a year of discharge, the intervention group had a lower rehospitalization rate than the control group (P<0.05), and the treatment compliance score was higher in the intervention group than that in the control group (P<0.05).

CONCLUSION

The "Internet + tertiary hospital-primary hospital-family nursing" model can improve self-care ability and treatment compliance of patients, improve their nerve defects and psychological status as well as quality of life, and reduce rehospitalization rate.

Pre-stroke and early post-stroke apathy is associated with increased risk of dementia 3 months after stroke

OBJECTIVES

Apathy is a frequent neuropsychiatric syndrome after stroke. We determined whether pre-morbid and early post-stroke apathy predicts dementia 3 months after stroke.

METHODS

We included ischemic stroke patients without dementia who participated in the Prospective Observational Polish Study on post-stroke delirium. We used the Neuropsychiatric Inventory and clinician-reported version of Apathy Evaluation Scale to score apathy symptoms before stroke and on day 8 after stroke. Patients underwent neuropsychological examination 3 months after stroke.

RESULTS

Of 422 patients with ischemic stroke and without pre-stroke dementia, 194 patients (mean age: 67.5 ± 12.3; 45.9% female) underwent neuropsychological examination. Dementia was diagnosed in 21.6% of them. Patients with dementia had higher apathy scores before stroke (mean: 0.9 ± 1.7 vs. 0.2 ± 0.9, p < 0.01) and on day 8 (mean: 37.2 ± 9.3 vs. 29.0 ± 9.6, p < 0.01). Depressive symptoms did not differ between groups. In multivariate analysis adjusted for age, diabetes mellitus, stroke severity and in-hospital delirium, apathy symptoms before stroke and on day 8 after stroke predicted post-stroke dementia (adjusted OR: 1.59, 95%CI: 1.13-2.26, p = 0.01 and OR: 1.06, 95%CI: 1.01-1.11, p = 0.03, respectively).

CONCLUSIONS

Pre-stroke and early post-stroke apathy independently from age, stroke severity and delirium predicted dementia 3 months after stroke. Apathy might be useful in identifying at-risk patients.

Long-term psychological outcomes following stroke: the OX-CHRONIC study

BACKGROUND

Stroke survivors rate longer-term (> 2 years) psychological recovery as their top priority, but data on how frequently psychological consequences occur is lacking. Prevalence of cognitive impairment, depression/anxiety, fatigue, apathy and related psychological outcomes, and whether rates are stable in long-term stroke, is unknown.

METHODS

N = 105 long-term stroke survivors (M [SD] age = 72.92 [13.01]; M [SD] acute NIH Stroke Severity Score = 7.39 [6.25]; 59.0% Male; M [SD] years post-stroke = 4.57 [2.12]) were recruited (potential N = 208). Participants completed 3 remote assessments, including a comprehensive set of standardized cognitive neuropsychological tests comprising domains of memory, attention, language, and executive function, and questionnaires on emotional distress, fatigue, apathy and other psychological outcomes. Ninety participants were re-assessed one year later. Stability of outcomes was assessed by Cohen's d effect size estimates and percent Minimal Clinically Important Difference changes between time points.

RESULTS

On the Montreal Cognitive Assessment 65.3% scored < 26. On the Oxford Cognitive Screen 45.9% had at least one cognitive impairment. Attention (27.1%) and executive function (40%) were most frequently impaired. 23.5% and 22.5% had elevated depression/anxiety respectively. Fatigue (51.4%) and apathy (40.5%) rates remained high, comparable to estimates in the first-year post-stroke. Attention (d = -0.12; 85.8% stable) and depression (d = 0.09, 77.1% stable) were the most stable outcomes. Following alpha-adjustments, only perceptuomotor abilities (d = 0.69; 40.4% decline) and fatigue (d = -0.33; 45.3% decline) worsened over one year. Cognitive impairment, depression/anxiety, fatigue and apathy all correlated with worse quality of life.

CONCLUSION

Nearly half of participants > 2 years post-event exhibited psychological difficulties including domains of cognition, mood, and fatigue, which impact long-term quality of life. Stroke is a chronic condition with highly prevalent psychological needs, which require monitoring and intervention development.

Post-Stroke Brain Health Monitoring and Optimization: A Narrative Review

Significant advancements have been made in recent years in the acute treatment and secondary prevention of stroke. However, a large proportion of stroke survivors will go on to have enduring physical, cognitive, and psychological disabilities from suboptimal post-stroke brain health. Impaired brain health following stroke thus warrants increased attention from clinicians and researchers alike. In this narrative review based on an open timeframe search of the PubMed, Scopus, and Web of Science databases, we define post-stroke brain health and appraise the body of research focused on modifiable vascular, lifestyle, and psychosocial factors for optimizing post-stroke brain health. In addition, we make clinical recommendations for the monitoring and management of post-stroke brain health at major post-stroke transition points centered on four key intertwined domains: cognition, psychosocial health, physical functioning, and global vascular health. Finally, we discuss potential future work in the field of post-stroke brain health, including the use of remote monitoring and interventions, neuromodulation, multi-morbidity interventions, enriched environments, and the need to address inequities in post-stroke brain health. As post-stroke brain health is a relatively new, rapidly evolving, and broad clinical and research field, this narrative review aims to identify and summarize the evidence base to help clinicians and researchers tailor their own approach to integrating post-stroke brain health into their practices.

Repetitive transcranial magnetic stimulation for apathy in patients with neurodegenerative conditions, cognitive impairment, stroke, and traumatic brain injury: a systematic review

Background

We aimed to determine the effects and tolerability of repetitive transcranial magnetic stimulation (rTMS) on apathy in patients with neurodegenerative conditions, mild cognitive impairment (MCI), stroke, and traumatic brain injury (TBI) via systematic review.

Methods

We conducted a systematic search in major electronic health databases, including PubMed, Scopus, and PsycINFO, covering the period from inception to June 2023. Comparative clinical trials and cohort studies, and studies with before-after designs were considered for inclusion. We used the Cochrane Risk of Bias and the National Institutes of Health (NIH) tools to assess methodological quality.

Results

Out of 258 records identified, 14 studies met our eligibility criteria (11 randomized controlled trials (RCT) and 3 studies utilized before-and-after designs) with a total of 418 patients (overall female-to-male ratio 1:1.17) included in the review. The overall methodological quality of the included studies was assessed to be fair to good. The stimulation parameters used varied considerably across the studies. The summary findings of our review indicate the following observations on the effects of rTMS on apathy: (1) the results of all included studies in Alzheimer's disease investigating the effects of rTMS on apathy have consistently shown a positive impact on apathy; (2) the majority of studies conducted in Parkinson's disease have not found statistically significant results; (3) a single study (RCT) on patients with primary progressive aphasia demonstrated significant beneficial effects of rTMS on apathy; (4) the trials conducted on individuals with MCI yielded varying conclusions; (5) one study (RCT) in chronic stroke suggested that rTMS might have the potential to improve apathy; (6) one study conducted on individuals with mild TBI did not find a significant favorable association on apathy; and (7) the use of different rTMS protocols on the populations described is generally safe.

Conclusion

The feasibility of utilizing rTMS as a treatment for apathy has been suggested in this review. Overall, limited evidence suggests that rTMS intervention may have the potential to modify apathy among patients with AD, PPA, MCI and chronic stroke, but less so in PD and mild TBI. These findings require confirmation by larger, well-designed clinical trials.

Psychological support after stroke: unmet needs and workforce requirements of clinical neuropsychological provision for optimal rehabilitation outcomes

Stroke services must detect and manage psychological and neuropsychological problems that occur after stroke, such as cognitive and language impairments, post-stroke apathy, post-stroke emotionalism, depression, anxiety, post-traumatic stress disorder, personality changes and suicidality. Stroke neuropsychology plays a key role in the assessment, understanding and management of these consequences of stroke, as well as contributing to complex case management, staff supervision and training. Where these provisions are absent from the stroke rehabilitation pathway, this significantly limits potential rehabilitation outcomes. To manage the scale of psychological and neuropsychological needs post stroke, clinical guidance recommends the use of a matched care system, in which these needs are triaged and matched with corresponding levels of support. Recent workforce guidelines provide clear professional recommendations for psychological staffing skill mix and threshold requirements for clinical oversight and clinical governance assurances.

'It's been an extraordinary journey': Experience of engagement from the perspectives of people with post-stroke aphasia

BACKGROUND

Engagement is recognized as an important factor in aphasia treatment response and outcomes, yet gaps remain in our understanding of engagement and practices that promote engagement from the client perspective.

AIMS

The purpose of this phenomenological study was to explore how clients with aphasia experience engagement during their inpatient aphasia rehabilitation.

METHODS & PROCEDURES

An interpretative phenomenological analysis approach guided the study design and analysis. Data were collected through in-depth interviews with nine clients with aphasia, recruited through purposive sampling, during their inpatient rehabilitation admission. Analysis was completed using a variety of analytic techniques including coding, memoing, triangulation between coders and team discussion.

OUTCOMES & RESULTS

The analysis revealed that for clients with aphasia in the acute phrase of recovery, the rehabilitation process resembles travelling on a journey through a foreign land. Successful engagement in the journey was accomplished when one had a therapist who served as a trusted guide and was able to be a friend, invested, adaptable, a co-creator, encouraging and dependable.

CONCLUSIONS & IMPLICATIONS

Engagement is a dynamic, multifaceted and person-centred process involving the client, provider and rehabilitation context. Findings from this work have implications for measuring engagement, training student clinicians to be skilled facilitators in engaging their clients and implementing person-centred practices that promote engagement within clinical settings.

WHAT THIS PAPER ADDS

What is already known on the subject Engagement is recognized as an important factor in rehabilitation treatment response and outcomes. Prior literature suggests that the therapist plays a critical role in facilitating engagement within the client-provider relationship. Communication impairments associated with aphasia may negatively impact a client's ability to develop interpersonal connections and participate in the rehabilitation process. There is a dearth of research directly exploring the topic of engagement in aphasia rehabilitation, particularly from the perspective of clients with aphasia. Capturing the client perspective can provide novel insights regarding practices to foster and maintain engagement in aphasia rehabilitation. What this paper adds to existing knowledge This interpretative phenomenological study revealed that for individuals with aphasia in the acute phase of recovery, the rehabilitation process resembles travelling on a sudden and foreign journey. Successful engagement in the journey was accomplished when one had a therapist who served as a 'trusted guide' and was able to be a friend, invested, adaptable, a co-creator, encouraging and dependable. Through the client experience, engagement is seen as a dynamic, multifaceted and person-centred process involving the client, provider and rehabilitation context. What are the potential or actual clinical implications of this work? The current study highlights the complexity and nuance of engagement within the rehabilitation context, which has implications for measuring engagement, training student clinicians to be skilled in engaging their clients and implementing person-centred practices that promote engagement within clinical settings. It is necessary to recognize that client and provider interactions (and thus engagement) are embedded in and influenced by the broader healthcare system. With this in mind, a patient-centred approach to engagement in aphasia care delivery cannot be achieved through individual efforts only and may require prioritization and action at the systems level. Future work is needed to explore barriers and facilitators to enacting engagement practices, in order to develop and test strategies to support practice change.

The prevalence of apathy in stroke patients: A systematic review and meta-analysis

BACKGROUND

Apathy is a frequent neuropsychiatric disorder in stroke patients. However, its prevalence rates have conflicting results across studies. This meta-analysis aimed to estimate the overall prevalence of apathy in stroke patients from 1990 to 2022.

METHODS

PubMed, Web of Science, Embase and PsycINFO were systematically searched to identify relevant articles published from January 1, 1990 to October 29, 2022. Literature quality was assessed with the National Institutes of Health Study Quality Assessment Tool. The pooled prevalence, subgroup analyses and meta-regression were calculated by STATA 16.0.

RESULTS

A total of 39 observational studies involving 5168 stroke patients were eligible for this meta-analysis. The pooled prevalence of apathy in stroke patients was 33.0% (95% CI, 27.6-38.4). Subgroup analyses showed that the pooled prevalence of apathy among stroke patients was higher in Japan (36.6%), China (33.7%) and Turkey (63.5%) compared to that in other countries (30.2%). The pooled prevalence of apathy was higher in ischemic stroke samples (36.1%) than in hemorrhagic stroke samples (14.4%). The pooled prevalence of apathy measured with the Apathy Evaluation Scale (38.3%) was the highest in stroke patients. Meta-regression presented that higher literature quality was significantly associated with lower prevalence, while stroke severity, mean age and female percentage were not significantly associated with the prevalence of apathy in stroke patients.

CONCLUSION

Our findings revealed that the overall prevalence of apathy in stroke patients was 33.0% based on the current evidence. Furthermore, the prevalence was significantly correlated with countries, stroke subtypes, apathy criteria, and literature quality.

Lower 25-hydroxyvitamin D is associated with severer white matter hyperintensity and cognitive function in patients with non-disabling ischemic cerebrovascular events

OBJECTIVES

This study aimed to investigate the potential correlations among serum 25-hydroxyvitamin D [25(OH)D] levels, white matter hyperintensity (WMH) and cognitive function in patients with non-disabling ischemic cerebrovascular events (NICE).

METHODS

This was a prospective investigation of 160 NICE patients with age of 40 years or older. Cognitive function was evaluated by the Montreal Cognitive Assessment (MoCA). White matter lesions were evaluated by WMH using Fazekas scores. Spearman correlation analysis and linear regression models were used to identify the associations between serum 25(OH)D levels and cognitive function. Binary logistic regression analysis models were used to evaluate the predictable value of serum 25(OH)D levels and WMH for cognitive impairment.

RESULTS

Patients with inadequate 25(OH)D levels had lower MoCA score (P=0.008), and a higher proportion of severe WMH (P=0.043). Spearman correlation analysis demonstrated that serum 25(OH)D concentrations were positively associated with MoCA score (rs=0.185, P=0.019) while negatively related to the proportion of severe WMH (sWMH) (rs=-0.166, P=0.036).The association between 25(OH)D concentrations and MoCA score remained significant in linear regression (adjusted β=0.012, 95%CI:0.001-0.203).Adjusted binary logistic regression analysis showed that the odds ratio of cognitive impairment with insufficient 25(OH)D concentration was 5.038 (95%CI:1.154-21.988) compared with the sufficient group and the sWMH (OR=2.728, 95%CI:1.230-6.051) was identified as an independent risk factor for cognitive decline in NICE patients.

CONCLUSION

Serum 25(OH)D levels and white matter lesions were independently and significantly associated with cognitive impairment in NICE patients.

Evaluation of apathy in non-clinical populations: validation, psychometric properties, and normative data of the Italian version of Apathy-Motivation Index (AMI)

INTRODUCTION

Evaluation of apathy in non-clinical populations is relevant to identify individuals at risk for developing cognitive decline in later stages of life, and it should be performed with questionnaires specifically designed for healthy individuals, such as the Apathy-Motivation Index (AMI); therefore, the aim of the present study was to validate the AMI in a healthy Italian population, and to provide normative data of the scale.

MATERIALS AND METHODS

Data collection was performed using a survey completed by 500 healthy participants; DAS, MMQ-A, BIS-15, PHQ-9, and GAD-7 were used to investigate convergent and divergent validity. Internal consistency and factorial structure were also evaluated. A regression-based procedure and receiver operating characteristics (ROC) analyses were used to evaluate the influence of socio-demographic variables on AMI scores and to provide adjusting factors and three cut-offs for the detection of mild, moderate, and severe apathy.

RESULTS

The Italian version of the AMI included 17 items (one item was removed because it was not internally consistent) and demonstrated good psychometric properties. The three-factor structure of AMI was confirmed. Multiple regression analysis revealed no effect of sociodemographic variables on the total AMI score. ROC analyses revealed three cut-offs of 1.5, 1.66, and 2.06 through the Youden's J statistic to detect mild, moderate, and severe apathy, respectively.

CONCLUSION

The Italian version of the AMI reported similar psychometric properties, factorial structure, and cut-offs to the original scale. This may help researchers and clinicians to identify people at risk and address them in specific interventions to lower their apathy levels.

Post-stroke delirium and challenges for the rehabilitation setting: A narrative review

INTRODUCTION

Post-stroke delirium (PSD) is a common yet underrecognized complication following stroke, with its effect on stroke rehabilitation being the subject of limited attention. The objective of this narrative review is to provide an overview of core issues in PSD including epidemiology, diagnostic challenges, and management considerations, with an emphasis on the rehabilitation phase.

METHODS

Ovid Medline and Google Scholar were searched through February 2023 using keywords related to delirium, rehabilitation, and the post-stroke period. Only studies conducted on adults (≥18 years) and written in the English language were included.

RESULTS

PSD affects approximately 25% of stroke patients, and often persists well into the post-acute phase, with a negative impact on rehabilitation outcomes including lengths of stay, function, and cognition. Certain stroke and patient characteristics can help predict risk for PSD. The diagnosis of delirium becomes more challenging when superimposed on stroke deficits (such as attentional impairment or other cognitive, psychiatric, or behavioural disorders), leading to underdiagnosis, overdiagnosis, or misdiagnosis. Particularly in patients with post-stroke language or cognitive disorders, common screening tools are less accurate. The multidisciplinary rehabilitation team should be involved in management of PSD as rehabilitative activities can be beneficial for patients who can participate safely. Addressing barriers to effective delirium care at various levels of the health care system can improve rehabilitation trajectories for these patients.

CONCLUSIONS

PSD is a disease entity commonly encountered in the rehabilitation setting, but it is challenging to diagnose and manage. New delirium screening tools and management approaches specific for the post-stroke and rehabilitation settings are needed.

Modulated effectiveness of rehabilitation motivation by reward strategies combined with tDCS in stroke: study protocol for a randomized controlled trial

Background

Stroke survivors often exhibit low motivation for rehabilitation, hindering their ability to effectively complete rehabilitation training task effectively and participate in daily activities actively. Reward strategies have been identified as an effective method for boosting rehabilitation motivation, but their long-term efficacy remains uncertain. Transcranial direct current stimulation (tDCS) has been recognized as a technique that facilitates plastic changes and functional reorganization of cortical areas. Particularly, tDCS can improve the functional connectivity between brain regions associated with goal-directed behavior when applied to the left dorsolateral prefrontal cortex (dlPFC). Combing reward strategies with tDCS (RStDCS) has been shown to motivate healthy individuals to exert more effort in task performance. However, research exploring the combined and sustained effects of these strategies on rehabilitation motivation in stroke survivors is lacking.

Methods and design

Eighty-seven stroke survivors with low motivation and upper extremity dysfunction will be randomized to receive either conventional treatment, RS treatment, or RStDCS treatment. The RStDCS group will receive reward strategies combined with anodal tDCS stimulation of the left dlPFC. The RS group will receive reward strategies combined with sham stimulation. The conventional group will receive conventional treatment combined with sham stimulation. tDCS stimulation is performed over 3 weeks of hospitalization, 20 min/time, five times a week. Reward strategies refers to personalized active exercise programs for patients during hospitalization and at home. Patients can voluntarily choose tasks for active exercise and self-report to the therapist so as to punch a card for points and exchange gifts. The conventional group will receive home rehabilitation instructions prior to discharge. Rehabilitation motivation, measured using RMS. RMS, FMA, FIM, and ICF activity and social engagement scale will be compared at baseline, 3 weeks, 6 weeks, and 3 months post-enrollment to evaluate patients' multifaceted health condition based on the ICF framework.

Discussion

This study integrates knowledge from social cognitive science, economic behavioral science, and other relevant fields. We utilize straightforward and feasible reward strategies, combined with neuromodulation technology, to jointly improve patients' rehabilitation motivation. Behavioral observations and various assessment tools will be used to monitor patients' rehabilitation motivation and multifaceted health condition according to the ICF framework. The aim is to provide a preliminary exploration path for professionals to develop comprehensive strategies for improving patient rehabilitation motivation and facilitating a complete "hospital-home-society" rehabilitation process.

Reward network dysfunction is associated with cognitive impairment after stroke

Stroke survivors not only suffer from severe motor, speech and neurocognitive deficits, but in many cases also from a "lack of pleasure" and a reduced motivational level. Especially apathy and anhedonic symptoms can be linked to a dysfunction of the reward system. Rewards are considered as important co-factor for learning, so the question arises as to why and how this affects the rehabilitation of stroke patients. We investigated reward behaviour, learning ability and brain network connectivity in acute (3-7d) mild to moderate stroke patients (n = 28) and age-matched healthy controls (n = 26). Reward system activity was assessed using the Monetary Incentive Delay task (MID) during magnetoencephalography (MEG). Coherence analyses were used to demonstrate reward effects on brain functional network connectivity. The MID-task showed that stroke survivors had lower reward sensitivity and required greater monetary incentives to improve performance and showed deficits in learning improvement. MEG-analyses showed a reduced network connectivity in frontal and temporoparietal regions. All three effects (reduced reward sensitivity, reduced learning ability and altered cerebral connectivity) were found to be closely related and differed strongly from the healthy group. Our results reinforce the notion that acute stroke induces reward network dysfunction, leading to functional impairment of behavioural systems. These findings are representative of a general pattern in mild strokes and are independent of the specific lesion localisation. For stroke rehabilitation, these results represent an important point to identify the reduced learning capacity after stroke and to implement individualised recovery exercises accordingly.

Altered Resting-State Brain Activity and Functional Connectivity in Post-Stroke Apathy: An fMRI Study

Apathy is a common neuropsychiatric disease after stroke and is linked to a lower quality of life while undergoing rehabilitation. However, it is still unknown what are the underlying neural mechanisms of apathy. This research aimed to explore differences in the cerebral activity and functional connectivity (FC) of subjects with post-stroke apathy and those without it. A total of 59 individuals with acute ischemic stroke and 29 healthy subjects with similar age, sex, and education were recruited. The Apathy Evaluation Scale (AES) was used to evaluate apathy at 3 months after stroke. Patients were split into two groups-PSA (n = 21) and nPSA (n = 38)-based on their diagnosis. The fractional amplitude of low-frequency fluctuation (fALFF) was used to measure cerebral activity, as well as region-of-interest to region-of-interest analysis to examine functional connectivity among apathy-related regions. Pearson correlation analysis between fALFF values and apathy severity was performed in this research. The values of fALFF in the left middle temporal regions, right anterior and middle cingulate regions, middle frontal region, and cuneus region differed significantly among groups. Pearson correlation analysis showed that the fALFF values in the left middle temporal region (p < 0.001, r = 0.66) and right cuneus (p < 0.001, r = 0.48) were positively correlated with AES scores in stroke patients, while fALFF values in the right anterior cingulate (p < 0.001, r = -0.61), right middle frontal gyrus (p < 0.001, r = -0.49), and middle cingulate gyrus (p = 0.04, r = -0.27) were negatively correlated with AES scores in stroke patients. These regions formed an apathy-related subnetwork, and functional connectivity analysis unveiled that altered connectivity was linked to PSA (p < 0.05). This research found that abnormalities in brain activity and FC in the left middle temporal region, right middle frontal region, right cuneate region, and right anterior and middle cingulate regions in stroke patients were associated with PSA, revealing a possible neural mechanism and providing new clues for the diagnosis and treatment of PSA.
