Abstract
in English, Portuguese

Prevalence studies of dementia and cognitive impairment in different cultures and environments are necessary.

Objective: To verify the prevalence of cognitive impairment and dementia in a rural homogeneous population from flooded areas in the Amazonian Basin.

Methods: A total of 163 subjects were interviewed with neurological, cognitive and functional evaluation. The individuals were classified as demented or cognitive impairment no dementia (CIND).

Results: cognitive impairment was observed in 11.4% (n=18 individuals). Ten out of the 18 were diagnosed as CIND and eight with dementia. The prevalence rate of dementia was 4.9% in subjects aged 50 years or over and of CIND was 6.1%. Considering only the elder group (>64 years of age), there was a 12.3% prevalence of dementia and 7.7% of CIND.

Conclusion: In a homogeneous population, we observed a similar prevalence of dementia to rates reported by studies in Brazil and in other developed and developing countries.

Estudos de prevalência de demência e de comprometimento cognitivo em diferentes culturas e ambientes são necessários.

Objetivo: Verificar a prevalência de comprometimento cognitivo e demência numa população rural homogênea de áreas alagadas da bacia Amazônica.

Métodos: Entrevistamos 163 indivíduos e avaliação neurológica, cognitiva e funcional. Foram classificados em dementados e comprometimento cognitivo sem demência (CCSD).

Resultados: Comprometimento cognitivo foi observado em 11,4% (n=18 indivíduos). Dez deles foram diagnosticados como CCSD e oito com demência. A taxa de prevalência foi de 4,9% em sujeitos com idade igual ou superior a 50 anos e 6,1% de CCSD. Considerando-se somente os idosos (>64 anos) a prevalência foi de 12,3% para demência e 7,7% para CCSD.

Conclusão: nesta população homogênea nós observamos uma prevalência de demência similar a outros estudos em nosso país e em outros desenvolvidos e em desenvolvimento.
