Montreal Cognitive Assessment (MoCA): Normative study for the Portuguese population

Abstract

The Montreal Cognitive Assessment (MoCA) is a brief cognitive screening instrument with good psychometric features and an excellent sensitivity in the early detection of mild cognitive decline. The MoCA was applied to a community-based sample of cognitively healthy adults (n = 650), stratified according to sociodemographic variables (age, gender, educational level, geographic region, geographic localization, and residence area), with a distribution similar to that observed in the Portuguese population. The normative data were determined according to age and education as these were the sociodemographic variables that most significantly contributed to the prediction of the MoCA scores, explaining 49% of their variance.

The impact of breast cancer treatments on sleep quality 1 year after cancer diagnosis

“…We excluded those previously treated with CTX and/or radiotherapy in the chest or axillary areas for other primary cancers, those that had received any treatment for breast cancer before, and those with a high probability of cognitive impairment (a score lower than 17, or lower than 16 for women over 65 years, in the Montreal Cognitive Assessment) [15].…”

Montreal Cognitive Assessment (MoCA): Validation Study for Vascular Dementia

“…This group was selected from the database of the MoCA's normative study for the Portuguese population to match each patient on variables that were found to be predictive of the MoCA's performance (educational level and age; Freitas, Simões, Alves, & Santana, 2011), and additionally on gender. Details of the controls' recruitment procedure, inclusion and exclusion criteria, and neuropsychological assessment have been described in a previous study (Freitas et al, 2011). …”

“…Due to this major difference, the correction point is not entirely applicable to the Portuguese population. The norms for the Portuguese population were calculated and stratified according to different educational levels (Freitas et al, 2011).…”

[P3–284]: The Montreal Cognitive Assessment: Normative Data From a Large Swedish Population‐based Cohort

“…Using the cut-off score from the original study, 37.3% of our normative population would have been incorrectly interpreted as cognitively impaired according to our evaluation of the population. The mean score of 26.0 (SD 2.3) was 1.0-4.2 points higher than in other normative studies [13][14][15][16][17][31][32][33], though lower than the average score of 27 for cognitively normal participants in the small original study (n = 90 healthy elderly controls). The very large normative study using data from the Dallas Heart Study (n = 2,653) included participants aged 18-85 [15].…”

“…When interpreting cognitive assessments, it is important to have population-based normative data suitable for the population on which it is being used. Several previous studies on normative data for the MoCA have included age groups below the average age of patients who are being assessed for cognitive impairment (including participants below the age of 45) [11][12][13][14][15], and some studies have derived norms based on a relatively small normal population [13,[16][17][18]. Hence, there is a need for normative data from a large population in a representative age group.…”
