Maintaining healthy blood pressure levels may be more critical too long-term cognitive function than previously understood, according to a large-scale study published this week. Researchers analyzing the medical records of nearly 2.8 million people in South korea found a correlation between both high and low blood pressure and an increased risk of dementia diagnosis. The findings add to growing evidence of a link between cardiovascular and brain health, prompting further inquiry into preventative measures against the disease which currently affects over 6.7 million Americans [[Alzheimer’s Association Fact Sheet]].
Blood Pressure Linked to Increased Dementia Risk in Large-Scale Study
A new study analyzing data from nearly 2.8 million people has revealed a significant association between blood pressure levels and the risk of developing dementia. Researchers at Hallym University Sacred Heart Hospital in South Korea found that both high and low blood pressure may increase the likelihood of a dementia diagnosis.
The research team, led by Professor Min-Woo Lee, examined health records from 2,798,464 individuals to investigate the relationship between blood pressure and dementia. The findings suggest that maintaining blood pressure within a healthy range is crucial for cognitive health as people age. This research underscores the importance of regular blood pressure monitoring and management as a preventative measure against dementia, a growing public health concern.
According to the study, individuals with systolic blood pressure below 110 mmHg or above 180 mmHg had a higher risk of being diagnosed with dementia compared to those with blood pressure levels between 140 and 179 mmHg. The study did not specify the types of dementia observed, but the overall association remained consistent across the large dataset.
“Our study highlights the importance of maintaining optimal blood pressure levels throughout life,” Professor Lee stated. The research team emphasized that further investigation is needed to determine the underlying mechanisms linking blood pressure and dementia, and to establish clear guidelines for blood pressure management to minimize dementia risk.
The findings have been published and are available for review. This research adds to a growing body of evidence suggesting that cardiovascular health plays a critical role in brain health and cognitive function.
