ABSTRACT
With the worldwide increase in longevity and rising prevalence of cognitive disorders in the aged population, efforts have been made to characterize mild cognitive impairment (MCI) and its prevalence and/or incidence in a number of countries, given MCI may be a pre-dementia phase of degenerative conditions. The aim of this review was to retrieve the available data on the prevalence and incidence of mild cognitive impairment (MCI) in Brazil and compare these with rates found by studies conducted in other countries. The Pubmed and Scielo databases were searched using the following search terms: mild cognitive impairment, prevalence, incidence, including studies in both English and Portuguese languages. Only one study on MCI prevalence has been published in Brazil, reporting a prevalence rate of 6.1% and incidence of 13.2/1000 persons-year among those aged 60 years or over. Prevalence rates for other countries are also reported. The prevalence and incidence of MCI found in Brazil is similar to rates observed in other countries.
Key words: mild cognitive impairment; epidemiology; prevalence; incidence; Brazil
RESUMO
Com o aumento da longevidade mundial e o crescimento da prevalência de distúrbios cognitivos nesta população, tem-se tentado caracterizar o comprometimento cognitivo leve e sua prevalência e/ou incidência nos diversos países. Uma vez que, este quadro pode ser uma fase pré-demencial dos quadros degenerativos. Esta revisão tentou recolher os dados disponíveis quanto a prevalência e incidência de comprometimento cognitivo leve (CCL) no Brasil e comparar em relação aos demais estudos em outros países. Foram revistas as bases PubMed e Scielo com os termos: comprometimento cognitivo leve, prevalência, incidência, foram incluídos estudos em inglês, português. Apenas um estudo de prevalência de CCL foi publicado no Brasil, com taxa de 6,1% e incidência de 13,2/1000 pessoas-ano entre aqueles de 60 anos ou mais. São mostradas as taxas nos demais países. A prevalência e incidência de CCL no Brasil encontram-se dentro das faixas observadas entre outros países.
Palavras-chave: comprometimento cognitivo leve; epidemiologia; prevalência; incidência; Brasil
