Undiagnosed Dementia Tied to Increased Mortality Risk
A recent study found that undiagnosed dementia is prevalent in both the US and Brazil, with significantly higher rates in Brazil. The research indicated that undiagnosed dementia is linked to increased mortality risk over four years compared to those without dementia. The findings highlight the need for improved detection and care for dementia, especially in lower-resource settings.
- ▪The proportion of undiagnosed dementia was 45% in the US and 76% in Brazil.
- ▪Undiagnosed dementia was associated with a higher risk of mortality compared to no dementia in both countries.
- ▪Younger age and absence of memory complaints were linked to undiagnosed dementia.

Opening excerpt (first ~120 words) tap to expand
TOPLINE:The proportion of dementia cases that were undiagnosed was high in the US and Brazil in a new cohort study, but the percentage was markedly higher in Brazil (76% vs 45%). Undiagnosed dementia was also associated with increased 4-year mortality compared to no dementia in both countries.METHODOLOGY:Researchers conducted a longitudinal observational study using data for more than 9500 participants (mean age, 75 years; 86% White individuals) in the 2016 US Health and Retirement Study and more than 3600 participants (mean age, 73 years; 43% White individuals) in the 2015-2016 Brazilian Longitudinal Study of Aging to determine the prevalence of undiagnosed dementia in adults at least 65 years of age.All participants were classified as having no dementia, undiagnosed dementia, or…
