A study conducted by researchers at Wake Forest University School of Medicine has found that managing blood pressure intensively for just over three years can significantly reduce the risk of mild cognitive impairment (MCI) or dementia. The positive effects of this treatment continued even after it was stopped, offering promising news for adults with high blood pressure and a higher risk of heart disease.
Published in the Neurology journal, the research followed 9,361 participants aged 50 and older from the U.S. and Puerto Rico. The participants were monitored over seven years, during which they underwent cognitive tests both in person and over the phone to check for MCI and dementia.
The participants were divided into two groups:
- Intensive Treatment Group: Received aggressive blood pressure management.
- Standard Treatment Group: Followed normal blood pressure control methods.
The study found that participants in the intensive treatment group had a significantly lower chance of developing cognitive problems compared to those in the standard treatment group.
High blood pressure is a well-known risk factor for cognitive decline and dementia. Cognitive issues, such as problems with memory, thinking, and decision-making, can greatly affect a person’s ability to perform everyday tasks and often lead to a loss of independence in older adults.
Dr. David M. Reboussin, a professor at Wake Forest University, explained:
“We found that those in the intensive treatment group had a lower rate of cognitive impairment compared to those in the standard treatment group.”
Dr. Jeff Williamson, a professor of geriatric medicine and co-author of the study, emphasized:
“Our research shows that controlling blood pressure more aggressively is a key strategy in preventing cognitive decline. Lowering blood pressure to targeted levels can improve quality of life and prolong active years for those with hypertension.”
For those with high blood pressure, this study highlights the importance of not only controlling blood pressure for heart health but also to protect the brain. Even just a few years of intensive treatment can help lower the risk of cognitive decline in the long run.

“While we know that high blood pressure damages the heart, this study highlights its equally significant impact on the brain. Effective blood pressure control is key to both preventing cognitive impairment and maintaining overall health as we age. BP should be kept below 140/90 and once started bp medicines should be taken daily like brushing your teeth daily . Chances of brain hemorrhage also decreases.”
Managing blood pressure effectively is a simple yet powerful way to improve overall health and protect cognitive function as we age.
Always consult your doctor for advice on managing hypertension.
