Blood pressure drugs may lower dementia risk in older people

Hypertension, commonly known as high blood pressure, affects millions of people worldwide. It’s a condition that often requires medication to control and reduce the risk of serious health problems like heart disease and stroke.

Now, a new study suggests that these medications may offer an unexpected benefit: reducing the risk of dementia in older adults.

The Study’s Background

As our population ages, issues related to cognitive health, like dementia, are becoming increasingly prevalent.

Dementia is a general term for conditions characterized by memory loss and other cognitive impairments that interfere with daily life. Alzheimer’s disease is one of the most well-known forms of dementia.

One common health condition among older adults is hypertension, which can lead to a range of problems if left uncontrolled.

Doctors often prescribe antihypertensive medications to help manage high blood pressure and lower the risk of heart disease and stroke.

The Research

To explore the potential link between antihypertensive medication use and dementia risk, researchers conducted a comprehensive study.

They collected data from 17 different studies involving more than 34,000 older adults, with an average age of 72.5 years.

Here are the important findings from this study:

Untreated Hypertension and Dementia Risk

Individuals with untreated hypertension, meaning they were not taking any blood pressure medications, were found to have a significantly higher risk of developing dementia.

This risk was compared to both healthy individuals without high blood pressure and those with treated hypertension who were taking antihypertensive medications. In essence, untreated hypertension seemed to increase the likelihood of developing dementia.

Treated Hypertension and Dementia Risk

Interestingly, individuals with treated hypertension, who were regularly taking antihypertensive medications, did not show a significantly higher risk of dementia when compared to healthy individuals without high blood pressure.

This finding suggests that antihypertensive medications may help reduce the dementia risk associated with hypertension.

Baseline Blood Pressure

The study did not find significant variations in the relationship between antihypertensive medication use, the presence of hypertension, and dementia based on an individual’s baseline blood pressure levels.

This indicates that the potential benefits of using antihypertensive medications to lower dementia risk may apply consistently to individuals with different initial blood pressure readings.


These research findings suggest that using antihypertensive medications to manage high blood pressure in older adults may have an added advantage: reducing the risk of dementia.

While these medications are primarily prescribed to control blood pressure and prevent conditions like heart disease, they might also contribute to maintaining cognitive health in later life.

It’s essential to understand that the link between hypertension, antihypertensive medications, and dementia risk is complex, and further research is needed.

However, these findings highlight the importance of addressing high blood pressure, especially in older adults, through appropriate medical interventions, including antihypertensive medications.

As always, if you or a loved one are concerned about blood pressure, dementia, or any related health issues, it’s crucial to consult with healthcare professionals.

They can provide personalized guidance on managing hypertension and any potential risks associated with it.

In summary, controlling high blood pressure with medication might offer a dual benefit: not only does it help protect against heart disease and stroke, but it may also reduce the risk of dementia in older adults.

This underscores the significance of monitoring and managing hypertension as a vital component of overall health and cognitive well-being as we age.

If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
