About The Study: In this cohort study, dementia mortality risk was greatest in mid-urbanicity and lower in dense urban cores and rural areas, and this gradient was largely attenuated by neighborhood conditions. These findings suggest that targeted improvements in modifiable neighborhood conditions may substantially reduce dementia mortality and advance equity, particularly in vulnerable communities.
