Incident dementia across neighbourhood material deprivation: Implications for underdiagnosis
Despite global findings of higher dementia incidence in lower SES, we found similar incidence across levels of material deprivation. Considering that recent work indicates that lower SES in Quebec is associated with poorer health outcomes consistent with literature, our discrepant finding of comparable incidence cases in the least and most deprived neighbourhoods indicates that there is likely severe underdiagnosis of dementia in people living in more materially deprived neighbourhoods in Quebec.
