Interethnic Differences in Dementia Epidemiology: Global and Asia-Pacific Perspectives
Narayanaswamy Venketasubramanian, Sheyaam Sahadevan, Ee Heok Kua, Christopher Chen, Tze Pin Ng. Dementia and Geriatric Cognitive Disorders, 2010-01-01
Topic: Risk, prevention and care in population studies
The burden of dementia will continue to rise globally, particularly in developing countries, many of which lie in the Asia-Pacific region. It was initially thought that both prevalence and incidence of dementia showed little geographic variation. More recent work has suggested differences: migrant populations attain rates between their homelands and adopted countries, and higher rates have been found in African Americans and Hispanics compared to Caucasian Whites, and also among native Australians. The only interethnic studies in the Asia-Pacific region were performed in Singapore, which showed lower standardized prevalence among ethnic Chinese compared to ethnic Malays and Indians, independent of vascular risk factors. There was conflicting information about the relative frequencies of Alzheimer's disease and vascular dementia between ethnic groups in Singapore. More research, with careful attention to potential cultural confounders, is needed to further explore and better understand interethnic differences in dementia epidemiology.

Key findings
- More recent work has suggested differences: migrant populations attain rates between their homelands and adopted countries, and higher rates have been found in African Americans and Hispanics compared to Caucasian Whites, and also among native Australians.
- The only interethnic studies in the Asia-Pacific region were performed in Singapore, which showed lower standardized prevalence among ethnic Chinese compared to ethnic Malays and Indians, independent of vascular risk factors.
Why it matters
This review reports that dementia rates differ between ethnic groups, with migrant populations attaining rates between their homelands and adopted countries, and higher rates in African Americans, Hispanics and native Australians compared to Caucasian Whites. It calls for more research, but it does not test a dementia treatment or cure.
