PEDRAZA L, Olga Lucia et al. MoCA and MMSE scores in patients with mild cognitive impairment and dementia in a memory clinic in Bogotá. Acta Neurol Colomb. [online]. 2014, vol.30, n.1, pp.22-31. ISSN 0120-8748.

Introduction. Some cognitive tests allow the evaluation of cognitive functions on the elderly in a short period of time. There are few studies in Colombia about cut-off point for the MMSE and the MoCA test. Objectives. To describe the distribution on scores on MMSE and MoCA test and the cut-off point with a better discrimination criteria for the diagnosis of mild cognitive impairment and dementia, in a sample of patients from Bogotá. Materials and methods. Two hundred forty eight patients were included in this study, being evaluated by a multidisciplinary team that followed an established protocol, on patients who attended to the Memory Clinic of HIUSJ between 2009-2012. MoCA test and MMSE scores that allow higher percentages of correctly classified patients were identified. Results. Seventy percent of patients with mild cognitive impairment and 69% of normal individuals had scores on MMSE below or equal to 28. Ninety-one percent of patients with MCI and 89% of normal patients, had scores below or equal to 25. Patients with any type of dementia had scores on MMSE below or equal to 27 and below or equal to 24 in MoCA test. Conclusion. According to the study, the screening of cognitive functions, using MoCA test, is more accurate than MMSE in patients with cognitive decline. The cut-off points, identified in our study, can be considered useful until now in primary attention, in patients with a high level of education.
