[Medical Today=Jaebaek Choi Reporter] Patients with untreated high blood pressure have been found to be at a greater risk of developing Alzheimer’s disease compared to those receiving treatment.
According to a study published in the journal Neurology by the American Academy of Neurology, patients who do not receive treatment for high blood pressure face a higher risk of developing Alzheimer’s disease than those who have been treated.
High blood pressure is one of the most underdiagnosed and poorly managed risk factors for dementia, with an estimated 46% of adults worldwide unaware that they have high blood pressure, and only 21% of those diagnosed receiving appropriate treatment.
The research team analyzed data from over 31,000 participants across 14 studies investigating cognitive changes and dementia diagnoses conducted in 14 countries, including Australia, the United States, Spain, and Japan. The average age of the participants was 72.
Among the participants, 9% had ‘untreated hypertension’, 51% had ‘currently treated hypertension’, 36% had low blood pressure, and 4% were uncertain about their hypertension status.
After adjusting for factors such as gender, age, and education level, the research team explored the relationship between blood pressure and the risk of developing Alzheimer’s dementia. They found that patients with ‘untreated high blood pressure’ had a 36% higher risk of developing Alzheimer’s disease compared to participants without high blood pressure.
Furthermore, they noted that patients with ‘untreated hypertension’ had a 42% higher risk of developing Alzheimer’s disease than those with ‘currently treated hypertension’.
The researchers stressed the importance of managing hypertension, stating that the difference in the risk of developing Alzheimer’s disease based on whether hypertension was treated was greater than anticipated.
However, it was also highlighted that the fact that patients who are ‘currently receiving treatment for hypertension’ had a lower risk of developing Alzheimer’s disease than those without a history of hypertension was not statistically significant, so interpretations should be made with caution.
The research team pointed out that as people age, both patients and healthcare providers may overlook the management of chronic conditions like high blood pressure, particularly when there are no obvious symptoms.
They emphasized that healthcare providers need to give patients accurate and reliable information about the risks associated with not taking antihypertensive medications, as well as the potential risks and side effects of these medications.
Experts indicated that while high blood pressure is a well-established risk factor for cardiovascular and cerebrovascular diseases, as well as vascular dementia, the findings of this meta-analysis further confirm the link between untreated high blood pressure and Alzheimer’s disease.
They advised that, while treating high blood pressure is crucial, it is also essential to consider the adverse effects that high blood pressure can have on various organs in the body.

Untreated High Blood Pressure and the Increased Risk of Alzheimer’s Disease: What You Need to Know

Understanding the Link: Hypertension and Alzheimer’s Risk
A recent study published in the journal Neurology by the American Academy of Neurology highlights a concerning correlation: patients who do not treat their high blood pressure (hypertension) possess a significantly greater risk of developing Alzheimer’s disease. The findings underscore hypertension as one of the most underdiagnosed and poorly managed risk factors for dementia, with approximately 46% of adults unaware of their condition and only 21% receiving appropriate treatment.
Study Insights: Data and Findings
The research analyzed data from over 31,000 participants across 14 countries—including Australia, the United States, Spain, and Japan—examining cognitive changes and dementia diagnoses. The average age of participants was 72 years, revealing various blood pressure statuses:
| Blood Pressure Status | Percentage of Participants |
|---|---|
| Untreated Hypertension | 9% |
| Currently Treated Hypertension | 51% |
| Low Blood Pressure | 36% |
| Uncertain Hypertension Status | 4% |
Risk Analysis: The Numbers Speak Volumes
After adjusting for variables such as gender, age, and education, researchers found:
- Patients with untreated high blood pressure have a 36% higher risk of developing Alzheimer’s disease compared to those with normal blood pressure.
- Individuals with untreated hypertension show a 42% increased risk of Alzheimer’s disease compared to those who are currently treated for hypertension.
These statistics emphasize the critical role of hypertension management in averting cognitive decline and protecting brain health.
Management is Key: Best Practices for Hypertension
Hypertension often goes unnoticed due to the lack of symptoms. Therefore, both patients and healthcare professionals must prioritize the management of blood pressure—especially in older adults. Here are essential tips for managing hypertension:
1. Regular Monitoring
Keep track of your blood pressure through regular check-ups and at-home monitors.
2. Healthy Lifestyle Choices
- Diet: Adopt a balanced diet rich in fruits, vegetables, whole grains, and low-fat dairy.
- Exercise: Engaging in regular physical activity can have profound effects on lowering blood pressure.
3. Medication Adherence
For those prescribed antihypertensive medications, following your doctor’s recommendations is essential. Understanding the benefits and potential side effects is crucial.
4. Regular Consultations
Consult with healthcare providers about the risks of untreated hypertension and the importance of routine check-ups.
Expert Opinions: The Broader Implications
Experts in the field have reinforced that high blood pressure is not just a cardiovascular risk factor; it significantly influences brain health and dementia risk. As dementia cases rise globally, awareness and education about the link between untreated hypertension and cognitive decline become paramount. This connection emphasizes the necessity of early diagnosis and consistent treatment of high blood pressure.
Real-Life Impact: A Case Study
Consider the case of Mr. Smith, a 73-year-old man who was unaware of his uncontrolled hypertension until a routine check-up revealed his 160/100 mmHg blood pressure reading. Despite feeling healthy, he was advised to start a treatment regimen. Mr. Smith’s proactive management—including lifestyle changes and medication led to a noticeable improvement in his overall health and cognition. Following his doctor’s advice not only helped manage his blood pressure but also promoted better brain health and reduced his risk for diseases like Alzheimer’s. Mr. Smith’s experience serves as a reminder of the often-overlooked link between hypertension and cognitive decline.
Conclusion: Take Control of Your Health
Managing high blood pressure is not merely about cardiovascular health; it is a vital component of safeguarding cognitive function and preventing debilitating diseases such as Alzheimer’s. Awareness, education, and proactive measures can significantly reduce the risks associated with untreated hypertension.
To aid in understanding and managing hypertension effectively, both patients and healthcare professionals must engage in conversations surrounding lifestyle modifications, the importance of medication adherence, and the vital link between blood pressure management and cognitive health.
