Share

Why the study?

The 2024 ESC guidelines introduced elevated blood pressure as a new category between non-elevated blood pressure and hypertension, but the dementia risk associated with this reclassification remains unclear.

Does elevated blood pressure or hypertension increase the risk of incident dementia in adults aged ≥40 years?

Population

2.8 million adults aged ≥40 years undergoing health screening in 2009 in South Korea

Comparison

Elevated blood pressure or hypertension vs non-elevated blood pressure

Design

Nationwide cohort study

Follow-up

Mean 8.1 years

Key result

Based on 2024 ESC criteria, elevated blood pressure (aHR 1.016; 95% CI 0.996-1.037) and hypertension (aHR 1.029; 95% CI 1.006-1.051) were associated with increased dementia risk versus non-elevated BP.

Overview

Supports 2024 ESC BP–dementia link in large cohort; leaves open whether BP lowering prevents incident dementia.

Structured PICO

Does elevated blood pressure or hypertension increase the risk of incident dementia in adults aged ≥40 years?

P
Population
2.8 million adults aged ≥40 years who underwent health screening in 2009 in South Korea, excluding those with prior dementia or dementia diagnosed within 1 year after cohort entry.
I
Intervention
Elevated blood pressure (SBP 120-139 mmHg or DBP 70-89 mmHg) and hypertension according to 2024 ESC definitions
C
Comparator
Non-elevated blood pressure
O
Outcome
Incident dementia (including Alzheimer's disease dementia, vascular dementia, and all-cause dementia) tracked until 2018hard clinical

Main Result

Effect estimate: aHR 1.016 (95% CI 0.996-1.037)

The 2024 ESC categories of elevated blood pressure and hypertension are associated with an increased risk of dementia, particularly vascular dementia, supporting early BP management.

Cite This Study

Jung et al. (2025) conducted a cohort in Dementia (n=2,800,000). Elevated blood pressure and hypertension vs. Non-elevated blood pressure was evaluated on Incident dementia (aHR 1.016, 95% CI 0.996-1.037). Based on 2024 ESC criteria, elevated blood pressure (aHR 1.016; 95% CI 0.996-1.037) and hypertension (aHR 1.029; 95% CI 1.006-1.051) were associated with increased dementia risk versus non-elevated BP.
