Dementia in elderly Malays--preliminary findings of a community survey

This is a study of the prevalence of dementia in elderly Malays living in the Eunos district of Singapore. The subjects included all Malays 65 years and more living in public housing, and they were first interviewed and screened for any cognitive deficit using the Malay version of the Elderly Cognitive Assessment Questionnaire (ECAQ). All those who scored 5 or less in the ECAQ were assessed again with a more detailed questionnaire called the Geriatric Mental State (GMS) schedule. This is the preliminary results of 149 subjects interviewed--77 men and 72 women. Data from the GMS were analysed by a computer diagnostic programme, AGECAT. There were only 6 cases of dementia and the overall prevalence of dementia in the sample was estimated as 4.0%. In the age group 65 to 74 years the rate was 2.5% and this increased to 10.3% in those 75 years and more. The prevalence of dementia in elderly Malays is higher than elderly Chinese in Singapore, but it is similar to the results of studies in New York and Liverpool. All the subjects with dementia were living with their families and they had good social resources.
