The Montreal Cognitive Assessment (MoCA) was designed by Nasreddine and colleagues as a screening tool for MCI and has become an increasingly popular screening tool, because it is a brief and easily administered even by non-specialist staff members and addresses frontal functions better than the widely used Mini-Mental Status Examination (MMSE). , PD-MCI is common and appears to place patients at risk of progressing to dementia even mild cognitive deficits in PD are associated with functional impairment, and poor quality of life (QOL). , Cognitive dysfunction in PD ranges from mild cognitive impairment (PD-MCI) to PD dementia (PDD) and increases the risk of nursing home placement, contributes to a more malignant course of illness, and exacerbates personal and socioeconomic burden. , Cognitive dysfunction is one of the important non-motor symptoms of PD. Non-motor manifestations contribute significantly to the morbidity resulting from Parkinson's disease (PD).

Keywords: Cross-cultural adaptation Malayalam Montreal Cognitive Assessment Parkinson′s disease validation Results: The Montreal Cognitive Assessment-Malayalam showed good internal consistency and test-retest reliability and its scores correlated with Mini Mental Status Examination (patients: R = 0.70 P < 0.001 healthy controls: R = 0.26 P = 0.04) and Addenbrooke's Cognitive Examination (patients: R = 0.8 P < 0.001 healthy controls: R = 0.52 P < 0.001) scores.Ĭonclusion: This study establishes the reliability of cross-cultural adaptation of Montreal Cognitive Assessment for assessing cognition in Malayalam-speaking Parkinson's disease patients for early screening and potential future interventions for cognitive dysfunction. Metric properties were assessed, and the scores were compared with the performance in validated Malayalam versions of Mini Mental Status Examination and Addenbrooke's Cognitive Examination. Materials and Methods: We developed a Malayalam (a south-Indian language) version of Montreal Cognitive Assessment and applied to 70 patients with Parkinson's disease and 60 age- and education-matched healthy controls. We tested its validity for use in non-English (Malayalam) speaking patients with Parkinson's disease.
