Reply to: “Diagnostic test accuracy of the Montreal Cognitive Assessment in the detection of post-stroke cognitive impairment under different stages and cutoffs: a systematic review and meta-analysis”

We read the review by Shi et al.  with interest and agree that early detection of post-stroke cognitive impairment (PSCI) is very important, both for clinicians and patients since accurate detection of cognitive deficits post-stroke can facilitate appropriate rehabilitation and discharge planning. The authors aimed to systematically review the literature to identify and quantify studies reporting the diagnostic accuracy of the Montreal Cognitive Assessment (MoCA)  in stroke survivors, assess the sensitivity and specificity of the MoCA, provide optimal cutoffs, and compare the MoCA with other available screening tools. These aims together with the suggestion at the start of the discussion that “a brief and sensitive screening tool is urgently needed,” prompted us to highlight a significant oversight. The Oxford Cognitive Screen (OCS)  was specifically developed as a brief cognitive screen for use post-stroke and although the OCS was used in the study by...
