Blood pressure drugs may lower dementia risk in older people

A recent study has found that taking blood pressure medications, known as antihypertensives, may reduce the risk of dementia in older adults who have high blood pressure. This research brings hope for improving brain health as people age.

Hypertension and Dementia

Hypertension, or high blood pressure, is a common condition among older adults. It can lead to serious health problems, including heart disease and stroke.

Additionally, there is evidence suggesting that high blood pressure may increase the risk of dementia, a condition characterized by a decline in cognitive abilities such as memory, thinking, and reasoning.

Alzheimer’s disease is the most common form of dementia, but other types also exist, all significantly impacting a person’s quality of life.

Study Overview

Researchers conducted a large-scale study involving over 34,000 older adults to examine whether antihypertensive medications could influence the development of dementia. The participants were categorized into three groups:

  1. Those with untreated hypertension (high blood pressure).
  2. Those with treated hypertension (high blood pressure managed with medication).
  3. Healthy individuals without hypertension.

These participants were observed over several years to track the onset of dementia.

Key Findings

The study revealed several important points:

  • Individuals with untreated hypertension had a higher risk of developing dementia compared to those without high blood pressure.
  • Those taking antihypertensive medications had a lower risk of dementia than those with untreated hypertension.
  • Interestingly, there was no significant difference in the dementia risk between those taking blood pressure medications and healthy individuals without hypertension.

Implications of the Findings

These results suggest that managing high blood pressure with medication may not only protect the heart but also lower the risk of developing dementia as one ages.

While the study shows a connection between blood pressure medications and reduced dementia risk, it doesn’t confirm that the medications directly cause this reduced risk.

Moving Forward

The study opens new possibilities for preventing dementia. Further research is necessary to fully understand how blood pressure medications affect dementia risk. However, this study is a promising step forward.

If you have high blood pressure, it’s essential to work with your healthcare provider to manage it effectively. Medications may be part of your treatment, but lifestyle factors such as a healthy diet, regular exercise, and not smoking are also crucial in controlling blood pressure.


Managing high blood pressure is vital for protecting both heart and brain health as you age. This study highlights the importance of overall health management for a better quality of life in later years.

For those concerned about blood pressure, understanding unhealthy habits, the impact of coffee intake, and the benefits of early time-restricted eating and plant-based diets can further aid in managing hypertension.

The detailed findings of this study are published in JAMA Network Open, contributing to the ongoing research and understanding of hypertension and dementia.
