It is free for clinical and research use. The objective of this study is to convert scores from the MMSE to MoCA and MoCA\u20105\u2010minute protocol (MoCA\u20105\u00a0min) and to examine the ability of the converted scores in detecting cognitive impairment after stroke or TIA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 904 patients were randomly divided into training (<jats:italic>n<\/jats:italic>\u00a0=\u00a0623) and validation (<jats:italic>n<\/jats:italic>\u00a0=\u00a0281) samples matched for demography and cognition. MMSE scores were converted to MoCA and MoCA\u20105\u00a0min using (1) equipercentile method with log\u2010linear smoothing and (2) Poisson regression adjusting for age and education. Receiver operating characteristics curve analysis was used to examine the ability of the converted scores in differentiating patients with cognitive impairment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean education was 5.8 (SD\u00a0=\u00a04.6; ranged 0\u201320) years. The entire spectrum of MMSE scores was converted to MoCA and MoCA\u20105\u00a0min using equipercentile method. Relationship between MMSE and MoCA scores was confounded by age and education, and a conversion equation with adjustment for age and education was derived. In the validation sample, the converted scores differentiated cognitively impaired patients with area under receiver operating characteristics curve 0.826 to 0.859.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We provided 2 methods to convert scores from the MMSE to MoCA and MoCA\u20105\u00a0min based on a large sample of patients with stroke or TIA having a wide range of education and cognitive levels.
