AbstractObjective: Post-stroke cognitive impairment is common, but mechanisms and risk factors are poorly understood. Frailty may be an important risk factor for cognitive impairment after stroke. We investigated the association between pre-stroke frailty and acute post-stoke cognition. Methods: We studied consecutively admitted acute stroke patients in a single urban teaching hospital during three recruitment waves between May 2016 and December 2017. Cognition was assessed using the Mini-Montreal Cognitive Assessment (min=0; max=12). A Frailty Index was used to generate frailty scores for each patient (min=0; max=100). Clinical and demographic information were collected, including pre-stroke cognition, delirium, and stroke-severity. We conducted univariate and multiple-linear regression analyses with covariates forced in (covariates included were: age, sex, stroke severity, stroke-type, pre-stroke cognitive impairment, delirium, previous stroke/transient ischemic attack) to investigate the association between pre-stroke frailty and post-stroke cognition. Results: Complete data were available for 154 stroke patients. Mean age was 68 years (SD=11; range=32–97); 93 (60%) were male. Median mini-Montreal Cognitive Assessment score was 8 (IQR=4–12). Mean Frailty Index score was 18 (SD=11). Pre-stroke cognitive impairment was apparent in 13/154 (8%) patients. Pre-stroke frailty was significantly associated with lower post-stroke cognition (Standardized-Beta=−0.40; p<0.001) and this association was independent of covariates (Unstandardized-Beta=−0.05; p=0.005). Additional significant variables in the multiple regression model were age (Unstandardized-Beta=−0.05; p=0.002), delirium (Unstandardized-Beta=−2.81; p<0.001), pre-stroke cognitive impairment (Unstandardized-Beta=−2.28; p=0.001), and stroke-severity (Unstandardized-Beta=−0.20; p<0.001). Conclusions: Pre-stroke frailty may be a moderator of post-stroke cognition, independent of other well-established post-stroke cognitive impairment risk factors. (JINS, 2019, 25, 501–506)

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.

Background Chronic renal failure and aging are suggested as risk factors for cognitive impairment (CI). We studied the prevalence of CI among peritoneal dialysis (PD) patients using Montreal Cognitive Assessment (MoCA), its impact on PD-related peritonitis in the first year, and the potential role of assisted PD. Methods One hundred fourteen patients were newly started on PD between February 2011 and July 2013. Montreal Cognitive Assessment was performed in the absence of acute illness. Data on patient characteristics including demographics, comorbidities, blood parameters, dialysis adequacy, presence of helpers, medications, and the number PD-related infections were collected. Results The age of studied patients was 59±15.0 years, and 47% were female. The prevalence of CI was 28.9%. Patients older than 65 years old (odds ratio [OR] 4.88, confidence interval [CI] 1.79 – 13.28 p = 0.002) and with an education of primary level or below (OR 4.08, CI 1.30 – 12.81, p = 0.016) were independent risk factors for CI in multivariate analysis. Patients with PD-related peritonitis were significantly older ( p < 0.001) and more likely to have CI as defined by MoCA ( p = 0.035). After adjustment for age, however, CI was not a significant independent risk factor for PD-related peritonitis among self-care PD patients (OR 2.20, CI 0.65 – 7.44, p = 0.20). When we compared patients with MoCA-defined CI receiving self-care and assisted PD, there were no statistically significant differences between the 2 groups in terms of age, MoCA scores, or comorbidities. There were also no statistically significant differences in 1-year outcome of PD-related peritonitis rates or exit-site infections. Conclusion Cognitive impairment is common among local PD patients. Even with CI, peritonitis rate in self-care PD with adequate training is similar to CI patients on assisted PD.

Background: There is paucity of data on the epidemiology of post-stroke cognitive impairment among African stroke survivors. The aim of this study is to report the profile and risk factors of post- stroke cognitive impairment among stroke survivors participating in the Stroke Investigative Research and Education Network (SIREN) Study. Methods: 1566 were evaluated with the Montreal Cognitive Assessment (MoCA) tool, the Community Screening Instrument for Dementia (CSID) and the Stick Design Test three months after the index stroke. Domain scores were derived for executive function, language memory and visuo-constructive/visuospatial domains. Cut off scores were derived from normative cognitive data obtained from comparable healthy stroke-free control subjects. We used conditional logistic regression to estimate odds ratios (OR) with 95% CIs. Results: Of 1566 stroke survivors [mean age 57.7 (13.4) years] who were assessed 3 months after stroke, 37% were impaired in global cognition and 18-43% were impaired in different domains of cognition (executive, memory, language and visuo-constructive). Stroke severity measured by modified NIHSS score had a strong significant negative association with cognitive function in all domains OR 1.96(1.32-2.91). Older age 1.04 (1.02-2.05), male gender 0.69 (0.50 -0.96), low intake of green leafy vegetables 2.83 (2.03 -3.95) and cardiac disease 1.86 (1.31 -2.75) were associated with poorer cognitive performance in different cognitive domains. Conclusion: The frequency of post-stroke cognitive impairment was high among African stroke survivors three months after the ictus. Diet low in green leafy vegetables is a potentially modifiable risk factor for post-stroke cognitive impairment among West Africans.

Background: The involvement of neuropsychiatry is reported in 6% to 91% of Systemic Lupus Erythematosus (SLE) patients. It can cause fatal morbidity and mortality. Memory impairment is one of the most common symptoms of neuropsychiatry involvement. This study aims to find out the performance of memory test in SLE patients using Indonesian version of Montreal Cognitive Assessment (MoCA-Ina).Method: This cross sectional study recruited 30 SLE patients. Cognitive abilities and patient’s memory were examined using Indonesian version of Montreal Cognitive Assessment (MoCA-Ina). Cognitive impairment was determined when total MoCA-Ina score was below 26. For memory evaluation, immediate recall or delayed recall impairment was determined when the patient failed in each memory subtests.Results: The mean of total MoCA-Ina score was 24.97 (SD±3.14). Fifty percent of the SLE patients had cognitive impairment, with the domain involved being delayed recall (86.67%), attention (60%), language (56.67%), abstraction (53.33%), and visuo-spatial/ executive function (36.67%). Most patients (86.67%) could completely repeat immediate recall. Whileonly 4 (13.33%) subjects could repeat delayed recall completely without any clue. Of the 26 SLE patients who failed to recall completely, 24 (92.3%) of them succeeded to recall completely after getting clue(s).Conclusion: Memory impairment is the most frequent cognitive impairment in SLE patients, especially in delayed recall. By using the memory subtests of MoCAIna, more than four fifth of patients with SLE was detected having delayed recall memory impairment and almost all of them could recalled completely after getting clue(s). This findings indicated that the finalstep of memory process retrieval in SLE was interrupted while being encoded, but retention pathway were stillintact.Keywords: Systemic Lupus Erythematous, Memory, MoCA-Ina
