High blood pressure has long been known as a risk factor for various health conditions, including heart disease and stroke. However, a new study published in the medical journal Neurology has revealed a concerning link between high blood pressure and Alzheimer’s disease. The research, conducted by study author Matthew J. Lennon, M.D., PhD, of the University of New South Wales in Australia, found that individuals age 60 and older with untreated high blood pressure may be at a higher risk of developing Alzheimer’s disease.
The study, which analyzed data from 31,250 people with an average age of 72, found that after four years, 1,415 of those individuals had developed Alzheimer’s disease. People with untreated high blood pressure were found to have a 36% increased risk of developing Alzheimer’s compared to those without the condition. Additionally, they had a 42% increased risk compared to those with high blood pressure who were taking blood pressure medication.
While previous research has indicated that taking blood pressure medications can reduce the risk of dementia, less is known about the impact of high blood pressure on Alzheimer’s risk. Dr. Lennon emphasized the importance of treating high blood pressure, stating that it is a leading cause of stroke and cerebrovascular disease and can be controlled with medication, reducing a person’s risk of these diseases.
The study’s findings suggest that untreated high blood pressure may increase the risk of Alzheimer’s disease, especially in older individuals. Dr. Lennon highlighted the importance of early intervention and treatment of high blood pressure to reduce the risk of Alzheimer’s disease as individuals age. He noted that even those in their 70s and 80s can benefit from controlling their blood pressure to lower their risk of developing Alzheimer’s.

Impact of High Blood Pressure on Alzheimer’s Risk
The study’s findings shed light on the potential impact of high blood pressure on Alzheimer’s risk, especially in individuals age 60 and older. Dr. Lennon emphasized the importance of treating high blood pressure to reduce the risk of Alzheimer’s disease, as untreated high blood pressure was associated with a higher likelihood of developing the condition.
Importance of Blood Pressure Control for Brain Health
The link between high blood pressure and Alzheimer’s disease underscores the importance of blood pressure control for brain health. Dr. Lennon noted that high blood pressure can interfere with oxygen and blood supply to the nerve cells of the brain, potentially accelerating the development of Alzheimer’s disease.
Strategies for Reducing Alzheimer’s Risk
In light of the study’s findings, there are several strategies individuals can adopt to reduce their risk of Alzheimer’s disease. Maintaining a healthy lifestyle, including adopting a plant-based diet, exercising regularly, and managing high blood pressure, can help lower the risk of developing Alzheimer’s as individuals age.
Dr. Marc Siegel, a professor of medicine at NYU Langone Medical Center and Fox News senior medical analyst, highlighted the significance of the study’s results in a conversation with Fox News Digital. He noted that Alzheimer’s involves neuroinflammation and the formation of plaques that interfere with neuronal communication. High blood pressure, along with other risk factors like high cholesterol and high glucose levels, can contribute to an increased risk of Alzheimer’s disease.
Dr. Elizabeth Landsverk, a geriatric medicine physician and author in California, echoed Dr. Siegel’s sentiments, emphasizing the role of high blood pressure, high cholesterol, and high glucose levels in increasing the risk of heart attack, stroke, and vascular dementia. She noted that the study’s findings indicate a decreased risk of Alzheimer’s disease among those treated for hypertension, highlighting the importance of managing high blood pressure as individuals age.
The study’s results suggest that treating high blood pressure is a crucial factor in reducing the risk of Alzheimer’s disease, regardless of age, sex, or racial background. Dr. Lennon emphasized the need for optimal care for all groups to reduce the risk of Alzheimer’s disease. However, he acknowledged potential limitations in the study, including variability in how dementia and high blood pressure were defined across different studies.
Despite these limitations, the study’s findings underscore the importance of blood pressure control for brain health and reducing the risk of Alzheimer’s disease. High blood pressure is a common condition that affects two-thirds of individuals over the age of 65 and approximately 1.3 billion people worldwide. Dr. Lennon emphasized the silent nature of high blood pressure, noting that it often presents no symptoms until a serious health event occurs.
In conclusion, the study’s findings highlight the critical role of blood pressure control in reducing the risk of Alzheimer’s disease. By managing high blood pressure through medication, lifestyle changes, and regular monitoring, individuals can lower their risk of developing Alzheimer’s as they age. Dr. Lennon’s research underscores the importance of early intervention and treatment of high blood pressure to protect brain health and reduce the risk of Alzheimer’s disease. As further research is conducted in this area, it is essential for individuals to prioritize blood pressure control as part of their overall health and well-being.
