Chile has surpassed this level, with individuals aged over 60 years accounting for over 13.5% of the population this rate is expected to increase to 20% by 2050. The United Nations defines a population as ageing when 7% or more individuals are aged 60 years or older. This is associated with a considerable economic cost: 160 billion euros per year in the European Union. 1 As a result of population ageing, Western Europe is the region with the greatest number of individuals aged ≥ 60 years, with an estimated 7 million cases. Globally, approximately 36 million people were living with dementia as of 2010, with prevalence showing a tendency to double every 20 years thus, 66 million people are expected to present the disease by 2030, and 115 million by 2050. The worldwide increases in life expectancy and population ageing entail new challenges in ensuring quality of life and individual well-being. Se presentan datos normativos de MoCA según las características sociodemográficas chilenas y puntos de corte propuestos para discriminar el rendimiento cognitivo normal de trastornos neurocognitivos según rangos de edad, ajustando los resultados al nivel educacional, la propuesta permitiría facilitar el uso del instrumento y disminuir la aparición de falsos positivos. Se propone protocolo de evaluación de resultados en percentiles y puntuaciones por rango de edad y puntuación escalar normalizada individual. Los adultos mayores con menor educación formal presentaron bajos resultados y menor rendimiento cognitivo.
El rendimiento cognitivo medio del total de la muestra fue de 24,04 ± 3,22, para un rango definido originalmente por el instrumento de 26 puntos sobre 30. La edad, educación y sexo explican 1-7% de la varianza. Se demuestra un efecto significativo de la edad y el nivel educativo sobre el rendimiento cognitivo general según MoCA. Se presenta estudio de validación para prueba diagnóstica de tipo descriptivo y correlacional, se evaluó a 526 sujetos, hombres y mujeres, de entre 18 y 90 años, sanos, del norte, centro y sur de Chile, analizando: el efecto de la edad, nivel educativo y sexo, para rendimiento de MoCA. El estudio busca normalizar y estandarizar el test MoCA para población chilena. El Montreal Cognitive Assessment (MoCA), test de cribado breve, de simple aplicación, válido y confiable, evalúa el estado cognitivo general, siendo útil en contextos de salud pública. This proposal would assist in the use of the test and reduce the rate of false positives.Įl envejecimiento poblacional implica un desafío para los países respecto a prevenir y detectar trastornos neurodegenerativos. We present normative data for the MoCA test in the Chilean population, and propose cut-off points for different age ranges to discriminate normal cognitive performance from neurocognitive disorders results are adjusted for education level. We propose a protocol for evaluating results by percentiles and scores for different age ranges, and an individual normalised scalar score. Older adults with less formal education presented poorer results and lower cognitive performance. The mean (standard deviation) score for the total sample was 24.04 (3.22), whereas the normal range originally defined for the instrument is 26-30 points. Age, education, and sex account for 1%-7% of variance. ResultsĪge and education level had a significant impact on general cognitive performance, as determined by MoCA score.
We analysed the effects of age, education level, and sex on MoCA performance.
We performed a descriptive, correlational validation study of the MoCA test, using a sample including 526 healthy individuals of both sexes, aged between 18 and 90 years, from the north, centre, and south of Chile. This study aims to normalise and standardise the MoCA test for the Chilean population. The Montreal Cognitive Assessment (MoCA), a short, simple, valid, and reliable screening test, assesses general cognitive status, and is useful in public health contexts. Population ageing poses a challenge for countries in preventing and detecting neurodegenerative disorders.
