Studies in stroke patients suggest that lacunar stroke and intracerebral hemorrhage might be more common in Chinese than Whites. We hypothesized that other manifestations of subclinical cerebral small vessel disease, namely white matter hyperintensities (WMH), lacunes, and microbleeds, are also more common in Chinese than Whites. We compared the community prevalence of these lesions between Han Chinese and White Australians.

Magnetic resonance imaging (1·5-Tesla) was performed on participants of the Shanghai Aging Study (n = 321, mean age 69 ± 6 years) and Tasmanian Study of Cognition and Gait (n = 397, mean age 72 ± 7 years). A single-rater recorded measures of WMH, lacunes, and microbleeds. We compared lesion prevalence between age- and gender-matched subgroups from the two cohorts. Among all subjects (n = 718), we performed multivariable …
