Our retrospective study examined the extent to which intact performance on the MoCA reflects intact cognition as determined by neuropsychological assessment.<h4>Methods</h4>In this retrospective study, cognitive profiles for 136 acute stroke patients admitted to the Acute Stroke Unit who had available MoCA and neuropsychological assessment data were examined.<h4>Results</h4>22% of our patients were deemed cognitively intact on the MoCA. Of these, 78% were found to be impaired (≤ 5%ile) on neuropsychological assessment in one or more cognitive domains. The most common impairments were in general intelligence, information processing speed and visual memory; three areas not assessed by the MoCA. In addition, a high proportion (up to 59%) of patients who scored the maximum points in one of the MoCA-specified domains were impaired on comparable neuropsychological assessment.<h4>Conclusions</h4>Our findings suggest that although the MoCA may be a useful screening tool post-stroke in detecting gross impairments, neuropsychological assessment is still necessary for a comprehensive and reliable detection of domain-specific cognitive deficits, which can more reliably inform us for realistic goal setting and vocational advice vital for effective rehabilitation.","is_dataset_classified":null,"base_score":4.356708826689592,"endowment":4.356708826689592,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24880539","pmcid":null,"openalex_id":"https://openalex.org/W1986283048","authors":[],"funders":[],"total_grants":0,"fwci":2.9611,"citation_percentile":0.90518772,"influential_citations":4,"citation_trend":[{"year":2014,"count":1},{"year":2015,"count":6},{"year":2016,"count":5},{"year":2017,"count":3},{"year":2018,"count":6},{"year":2019,"count":7},{"year":2020,"count":6},{"year":2021,"count":9},{"year":2022,"count":12},{"year":2023,"count":7},{"year":2024,"count":7},{"year":2025,"count":5},{"year":2026,"count":3}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0022510X14002950?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022510X14002950?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.jns.2014.05.005","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/24880539","host_type":"repository"},{"url":"http://discovery.ucl.ac.uk/1432921/","host_type":"repository"},{"url":"http://discovery.ucl.ac.uk/1443136/","host_type":"repository"},{"url":"http://hdl.handle.net/10447/99302","host_type":"repository"}],"fields_of_study":["Dementia and Cognitive Impairment Research","Spatial Neglect and Hemispheric Dysfunction","Traumatic Brain Injury Research","Psychology","Medicine","Aged","Aged, 80 and over","Cognition Disorders","Female","Humans","Male","Middle Aged","Neuropsychological Tests","Stroke","United Kingdom"],"mesh_terms":["Aged","Aged, 80 and over","Cognition Disorders","Female","United Kingdom","Humans","Male","Middle Aged","Neuropsychological Tests","Stroke"],"keywords":["Montreal Cognitive Assessment","Neuropsychology","Neuropsychological assessment","Cognition","Stroke (engine)","Psychology","Rehabilitation","Population","Physical medicine and rehabilitation","Acute stroke","Medicine","Audiology","Physical therapy","Psychiatry","Cognitive impairment","Stroke","Vascular disease","Cognitive Assessment","Moca"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Quality Education"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-27T18:58:18.421132Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
