Dementia Risk Within Married CouplesPrevious studies have suggested that spouses of individuals with dementia may be at increased risk of developing dementia themselves, but evidence regarding subgroup variation and absolute risk has remained limited. Understanding whether this risk extends across demographic, socioeconomic, and family contexts has remained important for developing household-level approaches to dementia risk assessment. Nationwide Cohort Study Using Taiwan’s Health Insurance DatabaseResearchers conducted a nationwide population-based cohort study using Taiwan’s National Health Insurance Research Database from 1998 to 2022, with follow-up through 2022. Spouses of individuals with dementia had a higher risk of all-cause dementia than unexposed spouses. Implications for Household-Level Dementia Risk AssessmentThese findings have shown that spouses of individuals with dementia face a higher risk of developing dementia themselves, with the association varying across family and socioeconomic contexts.
