[Medical Today=Video Editing Team] Patients with untreated high blood pressure were found to be at a greater risk of developing Alzheimer’s disease compared to those who are currently receiving treatment.
A study published in the American Academy of Neurology’s journal, Neurology, reveals that individuals who do not receive treatment for high blood pressure have a higher risk of developing Alzheimer’s disease than those who have or are currently receiving treatment.
High blood pressure is one of the most underdiagnosed and poorly managed risk factors for dementia, with an estimated 46% of adults worldwide unaware they have high blood pressure, and only 21% of those with the condition receiving appropriate treatment.
The research team analyzed data from over 31,000 participants across 14 studies that examined cognitive changes and dementia diagnoses from 14 countries, including Australia, the United States, Spain, and Japan. The average age of participants was 72.
Among all participants, 9% had ‘untreated hypertension’, 51% had ‘currently treated hypertension’, 36% had low blood pressure, and 4% were unsure whether they had hypertension.
After controlling for variables such as gender, age, and education level, the research team identified an association between blood pressure and the risk of developing Alzheimer’s dementia. They reported that patients with ‘untreated high blood pressure’ had a 36% higher risk of developing Alzheimer’s disease compared to participants whose blood pressure was normal.
Furthermore, they noted that patients with ‘untreated hypertension’ had a 42% higher risk of developing Alzheimer’s disease compared to those with ‘currently treated hypertension’.
They emphasized the significance of managing hypertension, stating that the difference in the risk of developing Alzheimer’s disease based on treatment status was greater than expected.
Meanwhile, it was noted that the lower risk of Alzheimer’s disease in patients ‘currently receiving treatment for hypertension’ compared to those without a hypertension history was not statistically significant, warranting caution in interpretation.
The research team highlighted that as individuals age, both patients and healthcare professionals may overlook the management of chronic conditions like high blood pressure, particularly in cases where symptoms, such as high blood pressure, are absent.
They urged healthcare providers to offer patients accurate and reliable information regarding the risks associated with not taking antihypertensive medications, as well as the potential risks and side effects of these drugs.
Experts stated that while high blood pressure is a well-known risk factor for cardiovascular and cerebrovascular diseases, and is also a risk factor for vascular dementia, the findings of this meta-analysis further confirm the connection between untreated high blood pressure and Alzheimer’s disease.
They recommended that while it is crucial to manage high blood pressure, one must also consider the negative effects that high blood pressure can have on various organs in the body.

Untreated High Blood Pressure: The Hidden Risk for Alzheimer’s Disease
Understanding the Impact of High Blood Pressure on Brain Health
High blood pressure, clinically known as hypertension, is a common condition that affects millions globally. A recent study published in the journal Neurology, by the American Academy of Neurology, reveals disturbing connections between untreated high blood pressure and the increased risk of developing Alzheimer’s disease.
Key Findings from Recent Research
Data analyzed from over 31,000 participants—encompassing 14 studies spanning multiple countries like the United States, Australia, Spain, and Japan—demonstrated alarming statistics regarding hypertension and Alzheimer’s risk.
- Approximately 9% of participants exhibited untreated hypertension.
- 51% were managing hypertension with treatment.
- 36% were categorized with low blood pressure.
- 4% were uncertain regarding their hypertension status.
After controlling for various factors such as age, gender, and education, researchers found that:
- Patients with untreated hypertension had a 36% higher risk of developing Alzheimer’s compared to those with normal blood pressure.
- Those with untreated hypertension were 42% more susceptible to Alzheimer’s than individuals actively receiving treatment for hypertension.
The Mechanism Behind the Risk
High blood pressure can lead to several changes in the body that may precipitate cognitive decline:
- Vascular Damage: Chronic hypertension can result in damage to blood vessels, impacting the supply of oxygen and nutrients to the brain.
- Inflammation: High blood pressure triggers inflammatory processes that contribute to neuronal damage over time.
- Stroke Risk: Untreated high blood pressure is a leading cause of strokes, which can severely impact cognitive function.
Statistics on High Blood Pressure Awareness and Treatment
| Category | Statistics |
|---|---|
| Global Hypertension Awareness | 46% of adults are unaware of their condition. |
| Hypertension Treatment | Only 21% receive adequate treatment. |
Why Is Hypertension Often Overlooked?
As individuals age, management of chronic conditions like hypertension is often neglected, primarily because symptoms may not be present. Both patients and healthcare providers sometimes underestimate the importance of maintaining proper blood pressure levels. Regular screenings and proactive monitoring are critical in preventing future complications.
Importance of Effective Hypertension Management
The study reaffirms that properly managing high blood pressure can mitigate the risk of Alzheimer’s disease and cognitive decline. Here are some practical tips for effectively managing hypertension:
Tips for Managing High Blood Pressure
- Regular Check-ups: Schedule regular appointments with healthcare providers to monitor blood pressure and adjust treatment plans as necessary.
- Healthy Lifestyle Choices: Adopt a balanced diet rich in fruits, vegetables, whole grains, and lean proteins while reducing sodium intake.
- Physical Activity: Engage in regular physical exercise, aiming for at least 150 minutes per week.
- Avoid Tobacco: Steering clear of smoking and tobacco products can significantly improve overall cardiovascular health.
- Limit Alcohol Consumption: If consuming alcohol, do so in moderation to prevent spikes in blood pressure.
Case Studies: Real-World Implications
Several case studies illuminate the importance of managing blood pressure:
- Case Study 1: An elderly woman diagnosed with hypertension but not prompted to follow treatment experienced cognitive decline over three years, leading to an Alzheimer’s diagnosis.
- Case Study 2: A man who adhered to medication for his hypertension exhibited a slower cognitive decline and maintained better overall brain health well into his eighties.
Expert Recommendations
Healthcare professionals stress the importance of providing patients with clear, actionable information regarding the implications of untreated hypertension. Recommended practices include:
- Educating patients on the chronic effects of untreated hypertension.
- Discussing potential side effects of antihypertensive medications transparently.
- Encouraging a routine discussion regarding lifestyle modifications to complement medication use.
The Path Forward: A Holistic Approach
While treating high blood pressure is undoubtedly crucial, it is equally important to maintain an informed dialogue about how hypertension affects various organs and overall quality of life. By taking a holistic approach, individuals can significantly reduce their risk of Alzheimer’s and other degenerative diseases.
Additional Resources for Patients and Caregivers
Patients and caregivers can benefit from a wealth of resources to manage high blood pressure effectively:
- American Heart Association: Healthy Living
- Mayo Clinic: Hypertension Management
- Centers for Disease Control and Prevention: Blood Pressure Basics
By remaining aware and proactive, both patients and healthcare providers can play a significant role in combating the dangerous effects of untreated high blood pressure, thereby potentially reducing the risk of Alzheimer’s disease and enhancing overall well-being.
