AustraliaA large-scale study from Taiwan involving nearly one million married adults found that when one spouse develops dementia, the other is significantly more likely to receive the same diagnosis. The research analyzed healthcare records from Taiwan’s national health insurance program between 1998 and 2022, comparing over 190,000 individuals with a spouse diagnosed with dementia to more than 760,000 without such a diagnosis. After adjusting for factors like age, income, and pre-existing health conditions, the study found that women whose partners developed dementia had a 74% higher relative risk of developing dementia themselves, while men had a 69% increased risk. Absolute risk calculations showed approximately 6.5% of women and 9.2% of men with a spouse diagnosed with dementia received their own diagnoses within five years. The findings suggest that shared health profiles—rather than direct transmission—are responsible for the correlation, pointing to patterns of 'assortative mating' where individuals tend to select partners with similar characteristics, including education, income, and health behaviors.
