![]() In addition, when these results were compared to the performance of healthy individuals, the MoCA appeared to be more effective than it is in real clinical settings. Yet researchers note that its reliability for diagnosing these problems was limited. The test was able to confirm a typical ability to think and rule out severe issues like dementia. One study from 2020 assessed the MoCA’s effectiveness in detecting cognitive concerns among older adults in an outpatient mental health clinic. It appears to be particularly effective at identifying cognitive changes in individuals with higher education levels or when mild cognitive changes are the main focus of clinical attention.īut its accuracy can be influenced by factors such as the characteristics of the person being tested and the setting in which the test is administered. Moreover, we described a systematic approach for adjusting the effects of age and education using fractional polynomials and provided suggestions on how to account for the nonlinear relationship that is frequently encountered between demographic factors and measures of cognitive performance.The accuracy of the MoCA test may vary depending on the specific context and population being assessed. ConclusionsWe presented normative data for the MoCA and the MoCA-MIS that will facilitate the use of the test in Brazil and, potentially, in other populations with substantial proportions of low-educated individuals. On the other hand, MoCA-MIS scores presented a nonlinear negative relationship with age, with an accelerated pattern at higher age levels (P<0.001). MoCA scores presented a nonlinear positive association with education tending to a plateau at higher levels (P<0.001). These data reinforce the need of adjusting cutoffs for schooling in populations with heterogeneous educational backgrounds. Even using a more conservative suggestion (22 points), 67% of our normative sample would be regarded as impaired. ResultsAccording to the original proposed cutoff (25 points), 87% of our sample would be considered impaired. To account for nonlinear relationships, we have used fractional polynomials that provide a flexible parameterization for continuous variables. The final sample consisted of 597 cognitively healthy Brazilians aged 50 to 90years. ![]() ![]() ![]() Dementia has been excluded with the Functional Activities Questionnaire. MethodsCommunity-dwelling outpatients were enrolled if they had no history of neurologic or psychiatric diseases and were not taking any drugs with effects on the central nervous system.
