چکیده
INTRODUCTION Harmonizing data across cohorts is important for validating findings or combining data in meta-analyses. We replicate and validate a previous conversion of MoCA to MMSE in PD. METHODS We used five studies with 1,161 PD individuals and 2,091 observations measured with both the MoCA and MMSE. We compared a previously published conversion table using equipercentile equating with log-linear smoothing to our internally derived scores. RESULTS Both conversions found good agreement within and across the studies when comparing true and converted MMSE (mean difference: 0.05; standard deviation: 1.84; median difference: 0; interquartile range: -1 to 1, using internal conversion). CONCLUSIONS These results show that one can get a reliable and valid conversion between two commonly used measures of cognition in PD studies. These approaches need to be applied to other scales and domains to enable large-scale collaborative analyses across multiple PD cohorts.

Cognitive Impairment in Patients with Coronary Artery Disease; Comparison of Montreal Cognitive Assessment (MoCA) and Mini Mental State Examination (MMSE)
Background & Objective: Mild cognitive impairment (MCI) is a transient state between normal condition and dementia. Available data indicates that coronary artery diseases (CAD) may increase the risk of MCI. Hence, the early detection of MCI can prevent the progression of cognitive decline. Materials & Methods: A sample of 65 subjects with degrees of CAD was enrolled to the study. For cogniti...

Conversion between mini-mental state examination, montreal cognitive assessment, and dementia rating scale-2 scores in Parkinson's disease.
Cognitive impairment is one of the earliest, most common, and most disabling non-motor symptoms in Parkinson's disease (PD). Thus, routine screening of global cognitive abilities is important for the optimal management of PD patients. Few global cognitive screening instruments have been developed for or validated in PD patients. The Mini-Mental State Examination (MMSE), Montreal Cognitive Asses...
