Taiwan Study Shows Spouses of Dementia Patients Have Significantly Higher Risk

A nationwide Taiwanese study examined nearly one million married adults using health‑care records from the National Health Insurance program (1998‑2022). Researchers compared over 190,000 people whose spouse received a new dementia diagnosis with more than 760,000 matched controls. After adjusting for age, sex, income, location and medical history, the analysis found that spouses of dementia patients were markedly more likely to develop dementia themselves. Women whose partners were diagnosed faced a 74 % higher relative risk, while men faced a 69 % increase. Over a five‑year follow‑up, 6.5 % of women and 9.2 % of men with a spousal diagnosis developed dementia, compared with 3.7 % and 5.8 % respectively in those without an affected partner. The findings underscore the shared health impact of long‑term caregiving. An accompanying essay highlights how growing old together can involve identity loss and caregiver burden, noting similar challenges in Malaysia where families often share the responsibility of caring for aging spouses or parents. Together, the research and personal reflections point to the need for greater support for couples navigating dementia and aging.
