Key result
Modern 85-year-olds have lower BP overall, with dementia consistently linked to lower systolic pressure.
Why the study?
Blood pressure has decreased in the general population, but whether this trend applies to the very old with and without dementia, and the prevalence of undetected or untreated hypertension in this group, remained unclear.
Population
Representative samples of 85-year-olds in Gothenburg, Sweden examined in 1986-1987 (n = 484) and 2008-2010 (n = 571)
Comparison
Cohorts examined in 1986-1987 vs 2008-2010, and individuals with vs without dementia
Design
Cross-sectional population study

Hypertension persists in nearly half with dementia despite lower BP trends; leaves open optimal management in the oldest-old.

Blood pressure levels have decreased over time among 85-year-olds, but individuals with dementia consistently have lower blood pressure than those without, while still having a high prevalence of hypertension.
Ribbe et al. (2021) conducted a cross-sectional in Dementia and hypertension (n=1,055). Examination in 2008-2010 vs. Examination in 1986-1987 was evaluated on Blood pressure levels and hypertension prevalence. Blood pressure was lower in 85-year-olds in 2008-2010 compared to 1986-1987, and individuals with dementia consistently had lower systolic blood pressure than those without dementia.
