Introduction: Post-stroke cognitive impairment (PSCI) has a considerable impact on patients and society. However, the characteristics and prevalence of long-term PSCI may be influenced by assessment methods and selection bias. We therefore used two cognitive screening methods to assess PSCI in ten-year stroke survivors, made comparisons with non-stroke individuals, and compared these screening methods. Methods: The Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were administered and compared in a population-based consecutive sample of ten-year stroke survivors. In addition, age- and sex-matched non-stroke controls were assessed with the MMSE. Regression analyses adjusting for education compared the stroke survivors’ MMSE performance with the controls. Moderate/severe cognitive impairment, approximating to dementia, was defined using MMSE<24 and MoCA<20 as cut-offs. To detect those with mild cognitive impairment, alternative cut-offs of MMSE<27 and MoCA<25 were also used. Results: In total, 127 of 145 stroke survivors participated. The total MMSE-scores were similar for stroke survivors (median 27) and 354 controls (median 27; p =0.922); as well as proportions with MMSE<24 (23% vs. 17%; p =0.175) or MMSE<27 (47% vs. 49%; p =0.671). After adjustment for education, stroke survivors showed an increased risk for moderate/severe cognitive impairment defined by MMSE<24 (OR=1.82; p =0.036). Executive dysfunction was seen in 42% of the stroke survivors vs. 16% of the controls as evaluated by MMSE ( p <0.001). According to MoCA, moderate/severe cognitive impairment (MoCA<20) was observed in 28% of the stroke survivors; any degree of cognitive impairment (MoCA<25) was seen in 61%; and 45-61% displayed executive function deficits. Conclusions: PSCI including executive dysfunction is common among ten-year stroke survivors, who have an increased risk of moderate/severe cognitive impairment compared to non-stroke controls. The prevalence of long-term PSCI may have been previously underestimated, and MoCA may be more suitable for post-stroke cognitive assessment.

The Relationship

ABSTRACT The relationship between depression and cognitive impairment, frequent after stroke, is complex and has not been sufficiently elucidated. Objective: To review the relationship between post-stroke depression and cognitive impairment. Methods: We performed a PubMed database search spanning the last ten years, using the terms post-stroke depression, cognitive dysfunction, cognitive impairment and neuropsychological tests. Our target studies were original quantitative studies that investigated the relationship between post-stroke depression (PSD) and cognitive impairment in stroke patients. Articles published in English, Spanish, Italian and Portuguese were considered. Selection criteria were the use of neuropsychological tests to assess cognitive function, and of either instruments to diagnose major depression, or scales to assess depressive symptoms, within the first three months after stroke. Results: Six original quantitative studies fulfilled the criteria. The prevalence of PSD within the first three months after stroke ranged from 22% to 31%. Incidence ranged from 25% to 27% and was evaluated in only two studies. PSD was associated with increased cognitive impairment. Cognitive impairment was reported in 35.2% to 87% of the patients. Post-stroke cognitive deficits were reported mostly in executive function, memory, language, and speed of processing. Conclusion: Executive dysfunction and depression occur in stroke survivors, are frequently coexistent, and also associated with worse stroke prognosis. Healthcare professionals need to address and provide adequate treatment for depression and executive dysfunctions in stroke patients early in the first three months after stroke. Future studies should evaluate the efficacy of programs evaluating the early detection and treatment of PSD and executive dysfunction in stroke survivors.

Background: Independence and reintegration into community roles are important patient-centered outcomes after stroke. Depression and cognitive impairment are common post-stroke conditions that may impair long-term function even years after a stroke. However, screening for these post-stroke comorbidities remains infrequent in stroke prevention clinics and the utility of this screening for predicting long-term higher-level function has not been evaluated. Aims: To evaluate the ability of a validated brief Depression, Obstructive sleep apnea, and Cognitive impairment screen (DOC screen) to predict long-term (2-3 years after stroke) community participation and independence in instrumental activities of daily living post stroke. Methods: One hundred twenty-four patients (mean age, 66.3 [standard deviation = 15.7], 52.4% male) completed baseline depression and cognitive impairment screening at first stroke clinic visit, and telephone interviews 2 to 3 years post stroke to assess community independence (Frenchay Activities Index [FAI]) and participation (Reintegration to Normal Living Index [RNLI]). A subset of these patients also consented to complete detailed neuropsychological testing at baseline. Univariate and multivariate linear (FAI) and logistic (RNLI) regression analyses were used to determine the individual relationship between baseline data (predictors) and follow-up scores. Results: Older age (β = −0.17, P = .001), greater stroke severity (β = 1.84, P = .015), more depressive (β = −2.41, P = .023), and cognitive (β = −2.15, P = .046) symptoms independently predicted poor instrumental activity ( R2 = .27; P < .001). Measures of executive dysfunction were the strongest correlates of poor instrumental activity. Higher depression risk was the only significant predictor of participation on the RNLI in regression modeling (odds ratio = 0.46, P = .028). Conclusions: Baseline DOC screening in stroke prevention clinics shows that symptoms of depression and cognitive impairment are independent predictors of impaired higher-level functioning and community reintegration 2 to 3 years after stroke. Novel rehabilitation and psychological interventions targeting people with these conditions are needed to improve long-term patient-centered outcomes.

Background: The long-term psychological consequences of stroke and how cognitive problems change over time after the first-year following stroke remain unclear. Particularly, trajectories of domain-specific and domain-general cognitive functions and how cognition interacts with mood, fatigue, and quality of life are not well described. Aims: To determine the prevalence, trajectories and wider impact of domain specific cognitive impairment in long term stroke survivors, in relation to mood, fatigue, and quality of life. Methods: Participants who previously took part in the Oxford Cognitive Screening study, completed the 6 month follow up with cognitive, mood, fatigue, and quality of life assessments and agreed to be contacted for future research will be recruited into OX-CHRONIC. The eligible cohort is between 2- and 9-years post stroke. Cognition will be assessed with a detailed neuropsychological battery, alongside questionnaire measures of mood, fatigue, activities of daily life and quality of life measures at two timepoints, one year apart. Additionally, medical records will be accessed to extract further clinical information about the stroke and patients may opt-in to wear an activity monitor for one week to provide fine-grained measures of sleep and activity. The study protocol and study materials were approved by the national ethics committee (REC Ref:19/SC/0520). Planned outputs: OX-CHRONIC will provide detailed data on the evolving cognitive profiles of stroke survivors over several years post-stroke. Estimates of long-term prevalence as well as the effect of changes in cognitive profiles on mood, fatigue and quality of life will be examined. This Study is funded by a Priority Programme Grant from the Stroke Association (SA PPA 18/100032).

BackgroundSubjective cognitive impairment (SCI) is common after acute ischemic stroke and adversely affects the quality of life. SCI is associated with an increased risk of developing mild cognitive impairment and dementia. Identifying biomarkers which could predict long-term cognitive outcomes of post-stroke SCI is of importance for early intervention. This study aims to investigate the association between circulating neurofilament light (NfL) and long-term cognitive function in patients with post-stroke SCI.MethodsThis longitudinal study recruited 304 patients with post-stroke SCI, and serum NfL levels were determined at baseline. These patients were followed up for 12 months for the observation of cognitive change. Cognitive performances were assessed by a Chinese version of the Telephone Interview of Cognitive Status-40 (TICS-40) scale.ResultsThe patients were divided into a progression group (as determined by decreased TICS-40 scores) and a stable group (as determined by increased or unchanged TICS-40 scores). The progression group had significantly higher serum NfL levels than the stable group at baseline. Serum NfL levels were predictive for longitudinal cognitive decline during follow-up.ConclusionThese findings imply that circulating NfL could predict the long-term cognitive change of patients with post-stroke SCI.

Introduction: Patients with poststroke cognitive impairment appear to be at higher risk of recurrent stroke and death. However, whether cognitive impairment after lacunar stroke is associated with recurrent stroke and death remains unclear. We assessed whether global or domain-specific cognitive impairment after lacunar stroke is associated with recurrent stroke and death. Methods: We considered patients from the Secondary Prevention of Small Subcortical Strokes (SPS3) trial with a baseline cognitive exam administered in English by certified SPS3 personnel, 14–180 days after qualifying lacunar stroke. We considered a baseline score of ≤86 on the Cognitive Assessment Screening Instrument to indicate global cognitive impairment, <10 on the Clock Drawing on Command test to indicate executive function impairment, and domain-specific summary scores in the lowest quartile to indicate memory and nonmemory impairment. We used Cox proportional hazards models to estimate the association between poststroke cognitive impairment and subsequent risk of recurrent stroke and death. Results: The study included 1,528 participants with a median enrollment time of 62 days after qualifying stroke. During a mean follow-up of 3.9 years, 11.4% of participants had recurrent stroke and 8.2% died. In the fully adjusted models, memory impairment was independently associated with an increased risk of recurrent stroke (hazard ratio, 1.48; 95% confidence interval [95% CI]: 1.04–2.09) and death (hazard ratio, 1.87; 95% CI: 1.25–2.79). Global impairment (hazard ratio, 1.66; 95% CI: 1.06–2.59) and nonmemory impairment (hazard ratio, 1.74; 95% CI: 1.14–2.67) were associated with an increased risk of death. Discussion/Conclusion: After lacunar stroke, memory impairment was an independent predictor of recurrent stroke and death, while global and nonmemory impairment were associated with death. Cognitive screening in lacunar stroke may help identify populations at higher risk of recurrent stroke and death.

Increased Risk

Two-thirds of older adults have multimorbidity (MM), or co-occurrence of two or more medical conditions. Mild cognitive impairment (CI) is found in almost 20% of older adults and can lead to further cognitive decline and increased mortality. Older adults with MM are the primary users of home health care services and are at high risk for CI development; however, there is no validated cognitive screening tool used to assess the level of CI in home health users. Given the prevalence of MM and CI in the home health setting, we conducted a review of the literature to understand this association. Due to the absence of literature on CI in home health users, the review focused on the association of MM and CI in community-dwelling older adults. Search terms included home health, older adults, cognitive impairment, and multimorbidity and were applied to the databases PubMed, CINAHL, and PsychInfo leading to eight studies eligible for review. Results show CI is associated with MM in older adults of increasing age, among minorities, and in older adults with lower levels of education. Heart disease was the most prevalent disease associated with increased CI. Sleep disorders, hypertension, arthritis, and hyperlipidemia were also significantly associated with increased CI. The presence of MM and CI was associated with increased risk for death among older adults. Further research and attention are needed regarding the use and development of a validated cognitive assessment tool for home health users to decrease adverse outcomes in the older adult population.

Background/aimsRecent research suggests an association between normal-tension glaucoma (NTG) and dementia. This study investigated whether cognitive impairment is more strongly associated with NTG than high tension glaucoma (HTG) using cognitive screening within an Australiasian Glaucoma Disease Registry.MethodsThe authors completed a case–control cross-sectional cognitive screening involving 290 age-matched and sex-matched NTG participants and HTG controls aged ≥65 randomly sampled from the Australian and New Zealand Registry of Advanced Glaucoma. Cognitive screening was performed using the Telephone Version of the Montreal Cognitive Assessment (T-MoCA). The T-MoCA omits points requiring visual interpretation, accounting for confounding factors related to vision loss in visually impaired participants. Cognitive impairment was defined by a T-MoCA score of <11/22. Cognition was compared between NTG and HTG participants using predetermined thresholds and absolute screening scores.ResultsA total of 290 participants completed cognitive assessment. There were no differences in NTG (n=144) and HTG (n=146) cohort demographics or ocular parameters at baseline. Cognitive impairment was more prevalent in the NTG cohort than the HTG cohort (OR=2.2; 95% CI 1.1 to 6.7, p=0.030). Though a linear trend was also observed between lower absolute T-MoCA scores in the NTG cohort when compared with the HTG cohort, this association was not statistically significant (p=0.108).ConclusionThis study demonstrated an association between NTG status and poor cognition, supporting the hypothesis that there exists a disease association and shared pathoaetiological features between NTG and dementia.

Transition Home

Introduction: More than 3.5 million family caregivers provide assistance with activities and instrumental activities of daily living for stroke survivors living at home. Studies consistently indicate that stroke family caregivers are inadequately assessed and under prepared for their new caregiver roles and responsibilities as stroke survivors transition home from inpatient rehabilitation. Several tools exist to assess caregivers once they have assumed the caregiving role, however, there are no tools assess stroke caregiver readiness prior to discharge. Research has indicated the need for a thorough and systematic pre-discharge assessment of the caregiver’s ability to assume the caregiving role. The purpose of this presentation is to describe ten critical stroke caregiver readiness assessment domains and to discuss their relevance for long-term outcomes for stroke survivors and family caregivers. Methods: In this grounded theory study, data were collected from19 persons with stroke and 19 family caregivers. Semi-structured interviews were conducted during inpatient rehabilitation and within 6 months post-discharge. First interviews focused on expectations for recovery and caregiving needs post-discharge. Follow-up interviews focused on how families managed the transition from rehabilitation to home and how their initial expectations matched the reality of their post-discharge experience. Interviews were analyzed using dimensional analysis and coded in NVivo data management software. Findings: Participants indicated that stroke was an overwhelming, life changing crisis event. Family members felt abandoned, isolated, and under prepared to assume the fulltime caregiving role as stroke survivors transitioned home. They described using ineffective or risky caregiving strategies that resulted in safety and health issues for both stroke survivors and caregivers. Ten pre-discharge caregiver readiness assessment domains were identified in the interviews and a corresponding stroke caregiver readiness assessment interview guide was developed. Conclusion: Stroke survivors and family caregivers are extremely vulnerable as they transition home from inpatient rehabilitation leaving them at risk for poorer health, depression, and increased risk for injury. In order to prevent these deleterious outcomes, caregivers should be assessed, and potential areas of risk identified and addressed prior to discharge from inpatient rehabilitation. As new interventions are developed to improve survival rates for persons with stroke, we must also develop and implement primary prevention strategies for family members who are called upon to provide care following discharge to protect their health and improve the long-term recovery outcomes for the stroke survivor.

Abstract Background Memory and cognitive deficits post stroke are common and associated with increased risk of future dementia. Rehabilitation tends to focus on physical recovery; however, once in the community, it is unclear what happens in the longer term to the stroke-survivor with new memory difficulties. Objective The aim of this qualitative study was to examine in stroke-survivors what factors influence contact with health professionals. Method Semi-structured interviews were conducted with stroke-survivors and their family carers where memory difficulties were reported at 6 months post stroke. A topic guide was used which sought to critically examine participants care experience following their stroke diagnosis. All participants were interviewed at baseline (around 6 months post stroke) and offered an interview at around 12 months post stroke. All interviews were conducted in the North East of England. All transcripts were coded and thematically analysed. Results Ten stroke-survivors (age range 72–84 years) were interviewed alongside five carers at baseline; eight stroke-survivors and four carers agreed to a follow-up interview. Three main barriers were identified: (i) fear of a dementia diagnosis; (ii) denial or minimization of symptoms leading to adaptation and (iii) obstacles to seeking help in the community. Conclusions With an ageing population and increase in stroke-survival, the burden of post-stroke cognitive impairment and dementia will only increase. Stroke-survivors and their family carers in this study have identified issues that may hinder their presentation to health care professionals at a personal and organizational level. Health professionals need to be aware of these potential issues when planning services for stroke-survivors.

Cognitive Problems

Introduction: Guidelines recommend screening all stroke admissions for cognitive impairment. Delirium may be an important contributor to cognitive problems, but available data are limited by potential selection biases and imperfect delirium assessment. We aimed to describe robust estimates of delirium occurrence (incidence and prevalence) and risk factors in an acute stroke unit (ASU). Methods: We collected data from sequential admissions to our University Hospital ASU over a 20 week period (Feb-July 2016). The only exclusion was where the clinical team felt that any form of assessment was inappropriate. We aimed to perform cognitive assessments at 48 hours post stroke. Cognitive assessments were based on mini Montreal Cognitive Assessment (m-MoCA) and GP-Cog informant interview to assess for pre-stroke dementia. We assessed for delirium based on DSM-V criteria. We described univariable and multivariable associations with delirium occurrence. Results: Across the study period, 184 strokes were admitted; median age 71 years (IQR:61-79). Some form of cognitive assessment was available for 178 (97%). In total. 152 had evidence of cognitive impairment on m-MOCA, 55 (31%) met criteria for delirium and 25 (15%) had pre-stroke dementia. Significant univariable associations with delirium were:age and pre-existing cognitive decline. On logistic regression:age, history of drug or alcohol misuse and pre-stroke mRS were all independently associated with delirium. Discussion: In an unselected ASU population a substantial proportion will have cognitive impairment based on screening. Delirium is common and contributes to this cognitive problems seen in acute stroke. Independent associations with delirium occurrence were identified but were non-modifiable. Our results have implications for policy and practice. As post-stroke cognitive impairment is multifactorial, screening delirium and pre-existing cognitive issues should form part of the initial assessment.
