ABSTRACT

ABSTRACT Background: Screening tests have been used for cognitive deficits in Parkinson's disease (PD). Objective: This study compared the Montreal Cognitive Assessment (MoCA) test, the Mini-Mental State Examination (MMSE) and the clock drawing test for this purpose. Methods: A total of 50 patients with PD were selected, 41 (82%) were diagnosed with dementia by the criteria of the Movement Disorder Society. The test Scales for Outcomes in Parkinson's Disease-Cognition (SCOPA-Cog) was used as the gold standard in comparison with the screening tests. Results: The MoCA test (AUC=0.906) had a sensitivity of 87.80% and specificity of 88.89%. When the MMSE was associated with the clock drawing test (AUC=0.936), it had a specificity of 66.67% and sensitivity of up to 97.56%. Conclusion: The study suggests that the MoCA test can be a good screening test in PD. However, MMSE associated with the clock drawing test may be more effective than the MoCA test.


RESUMO Embasamento: Diversos testes têm sido utilizados como ferramenta de triagem para déficits cognitivos na doença de Parkinson (DP). Objetivo: Este estudo comparou os testes Montreal Cognitive Assessment (MoCA), Mini Exame do Estado Mental (MEEM) e teste do relógio para essa finalidade. Métodos: Foram selecionados 50 pacientes com DP, dos quais 41 (82 %) foram diagnosticados com demência pelos critérios da Movement Disorder Society. O teste Scales for Outcomes in Parkinson's Disease-Cognition (SCOPA-Cog) foi usado como padrão-ouro na comparação com os testes de triagem. Resultados: O teste MoCA (AUC=0,906) apresentou sensibilidade de 87,80% e especificidade de 88,89%. Quando o MEEM foi associado ao teste do relógio (AUC=0,936), apresentou especificidade de 66,67% e sensibilidade de até 97,56%. Conclusão: O estudo sugere que o teste MoCA pode ser um melhor teste de triagem na DP. Entretanto, o MEEM associado ao teste do relógio pode ser mais eficiente que o MoCA.
