Simple measurements from routine blood pressure checks may predict dementia risk decades before symptoms appear. New research presented at the American College of Cardiology’s Annual Scientific Session highlights two metrics-pulse pressure-heart rate index and estimated pulse wave velocity-as potential predictors.
Data shows rates of dementia are expected to rise as populations age, with hypertension a known contributor. Lead author Dr. Newton Nyirenda emphasized that managing blood pressure could help preserve cognitive health.
Researchers analyzed data from over 8,500 adults aged 50 and older in the SPRINT trial. Results showed a strong link between elevated pulse pressure-heart rate index and a 76% higher dementia risk for those under 65.
Another study found adults with increasing pulse wave velocity were more likely to develop dementia, even after adjusting for other factors.
Further studies are needed to confirm these findings and explore whether improving vascular health reduces dementia risk.
