Cognitive domains assessed by moca4/18/2024 The participants with MoCA scores ≤ 23 for impaired cognition were more likely to be functionally dependent. The MoCA score of ≤ 23 for impaired cognition had equal sensitivity and specificity for predicting functional dependence 3 months after stroke.ĭiscussion and Conclusion: Cognitive function assessed with the MoCA within 36–48 h after stroke could predict functional dependence 3 months later. The MoCA quartiles were a significant predictor of functional dependence 3 months after stroke as an individual variable ( p < 0.001, AUC = 0.72) and when adjusted for covariates such as age at stroke onset, living arrangement prior to stroke, and ADL measured with BI within 36–48 h after stroke ( p = 0.01, AUC = 0.84). Results: A total of 305 participants were included in the study (mean age: 68.8 years, n = 179 men). The MoCA score that had equal sensitivity and specificity was chosen as the optimal score for predicting functional dependence. Receiver operating characteristic curves (AUC) were used for identifying the optimal cutoff score on the MoCA for predicting functional dependence. The predictive characteristics of the MoCA were investigated using logistic regression analyses. Functional outcome 3 months after stroke was studied with the modified Rankin Scale. Cognitive function and activities of daily living (ADL) were assessed with the MoCA and the Barthel Index (BI), respectively, 36–48 h after stroke. The research database from a stroke unit at the Sahlgrenska University Hospital was linked with the Swedish Stroke Register-Riksstroke. Materials and Methods: This was a longitudinal cohort study. The secondary aim was to identify an optimal threshold for the MoCA score that could predict functional dependence. The primary aim of this study was to investigate if cognitive function, assessed with the Montreal Cognitive Assessment (MoCA) 36–48 h after stroke, could predict functional dependence 3 months later. Introduction: After a stroke, cognitive impairment is commonly associated with poor functional outcomes. 2Centre for Person-Centred Care (GPCC), University of Gothenburg, Gothenburg, Sweden.1Institute of Neuroscience and Physiology, Rehabilitation Medicine, University of Gothenburg, Gothenburg, Sweden. The OCS detects important cognitive deficits after stroke not assessed in the MoCA, it is inclusive for patients with aphasia and neglect and it is less confounded by co-occurring difficulties in these domains.Ĭognition Cognitive assessment Neuropsychology Stroke.Tamar Abzhandadze 1 * Lena Rafsten 1,2 Åsa Lundgren Nilsson 1,2 Annie Palstam 1 Katharina S. Unlike the MOCA, the OCS was not dominated by left hemisphere impairments but gave differentiated profiles across the contrasting domains. OCS was more sensitive than MoCA overall (87 vs 78% sensitivity) and OCS alone provided domain-specific information on prevalent post-stroke cognitive impairments (neglect, apraxia and reading/writing ability). The incidence of acute cognitive impairment was high: 76% of patients were impaired on MoCA, and 86% demonstrated at least one impairment on the cognitive domains assessed in the OCS. The incidence of cognitive impairments on both the MoCA and OCS sub-domains was calculated and differences in stroke specificity, cognitive profiles and independence of the measures were addressed. Inclusivity was assessed in terms of completion rates and reasons for non-completion were evaluated. Demographic data, lesion side and Barthel scores were recorded. A cross-sectional study with a consecutive sample of 200 stroke patients within 3 weeks of stroke completing MoCA and OCS. This study compared the use of the MoCA and the OCS in acute stroke with respect to symptom specificity and aspects of clinical utility. The Oxford Cognitive Screen (OCS) provides a domain-specific cognitive profile designed for stroke survivors. Cognitive assessments after stroke are typically short form tests developed for dementia that generates pass/fail classifications (e.g.
