![]() O grupo controle foi cognitivamente normal. ![]() Foram excluídos pacientes com menos de 3 anos de escolaridade, com distúrbios sensoriais, distúrbios psiquiátricos e demência moderada a grave. Validar o MoCA em idosos e estudar sua utilidade no CCL e demência leve.Įste estudo incluiu 399 indivíduos acima de 60 anos avaliados no departamento cognitivo-comportamental (2017-2018). Até o momento, nenhuma validação argentina com adaptação transcultural da versão em espanhol havia sido relatada. O MoCA é um teste breve e útil para diagnosticar comprometimento cognitivo leve (CCL) e demência leve. The MoCA-A is an accurate reliable screening test for MCI and MD in Argentina. When adding a single point to the score in patients with ≤12 years of education, the specificity of the test reached 81%. Adopting a cut-off score ≥25 (YI=0.55), the sensitivity for MCI was 84.8% and for MD 100%, with specificity of 69.7%. MoCA-A performance correlated with educational level (r: 0.406 p<0.00001). MoCA-A score differed significantly among groups (p<0.0001). Mean educational level was 10.34 years (SD 3.5 years). A locally adapted MoCA (MOCA-A) was administered to the patients and controls. Participants were classified according to neuropsychological assessment and clinical standard criteria into Control, MCI or MD groups. The control group comprised cognitively normal subjects. ![]() Patients with<3 years of education, sensory disturbances, psychiatric disorders, or moderate-severe dementia were excluded. This study included 399 individuals over 60 years old evaluated in the Cognitive-Behavioral Department (2017-2018). To validate the MoCA in the elderly and study its usefulness in MCI and MD. To date, no Argentine cross-cultural adapted validations of the Spanish version have been reported. Combining the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) with the MMSE did not improve diagnostic utility.The MoCA is a brief useful test to diagnose mild cognitive impairment (MCI) and mild dementia (MD). Use of a cut-off lower than that specified in the index study may be required to improve overall test accuracy and specificity for some loss of sensitivity in populations with a high prior probability of cognitive impairment. In a memory clinic population, MoCA proved sensitive for the diagnosis of cognitive impairment. Combining MoCA with the MMSE - either in series or in parallel - did not improve diagnostic utility above that with either test alone. Downward adjustment of the MoCA cut-off to ≥20/30 maximized test accuracy and improved specificity (0.95) for some loss of sensitivity (0.63). Using the cut-offs for MoCA and MMSE specified in the index paper (≥26/30), MoCA was more sensitive than MMSE (0.97 vs 0.65) but less specific (0.60 vs 0.89), with better diagnostic accuracy (area under Receiver Operating Characteristic curve 0.91 vs 0.83). MoCA proved acceptable to patients and was quick and easy to use. ![]() Patients were diagnosed using standard clinical diagnostic criteria for dementia (DSM-IV) and mild cognitive impairment (MCI cognitive impairment prevalence = 43%) independent of MoCA test scores. This was a pragmatic prospective study of consecutive referrals attending a memory clinic (n = 150) over an 18-month period. This aim of this study was to assess the clinical utility of the Montreal Cognitive Assessment (MoCA) as a screening instrument for cognitive impairment in patients referred to a memory clinic, alone and in combination with the Mini-Mental State Examination (MMSE).
