A study has found a cross-sectional association between neighbourhood economic disadvantages and prevalence of dementia among 21,008 older adults aged 65 years and over. Data were extracted from 18 Elderly Health Centres of the Department of Health from 2009 to 2011. The results suggested that the higher the neighbourhood economic disadvantage, the higher the prevalence of dementia in the neighbourhood (Guo et al., 2019).
