Untreated hypertension can increase the risk of Alzheimer's by up to 42%.

Hypertension is a medical condition that affects more than 42% of the adult population in Spain, according to the Spanish Journal of Cardiology. This alarming statistic underscores the importance of paying attention to this disease, especially given its link to severe health conditions such as cardiovascular accidents. However, a new study has revealed that the dangers of hypertension extend beyond cardiovascular issues, reaching into cognitive risks that can affect the quality of life for millions of people.

Published in the journal Neurology, the study by a team of researchers from the University of New South Wales (Australia) provides a comprehensive analysis of the effects of untreated hypertension on brain health. In total, the meta-analysis gathered data from over 31,000 individuals aged 60 and older, with an average age of 72, and found that those with untreated hypertension face a 42% higher risk of developing Alzheimer's compared to those who manage their blood pressure.

The follow-up conducted over an average of four years revealed that, among the participants, more than 1,400 developed Alzheimer's. Significantly, 9% of the individuals had untreated hypertension, 51% were under pharmacological treatment, and 36% did not have hypertension. This breakdown highlights the prevalence of hypertension in the population and the urgent need for treatment.

The study's findings are particularly concerning, as after adjusting for other factors that could influence the development of the disease, it was determined that those with untreated hypertension have a 36% higher risk of developing Alzheimer's compared to those who do not have the disease. When this group is compared to those who were receiving treatment, the risk increases to 42%.

Although the researchers have not clarified the exact mechanism by which hypertension contributes to Alzheimer's, it is evident that high blood pressure can affect blood flow in critical regions of the brain. This effect can be devastating, as compromised blood circulation can lead to irreversible brain damage.

Moreover, hypertension is not only related to Alzheimer's but also to vascular dementia, a type of cognitive decline that can coexist with Alzheimer's disease and exacerbate its symptoms. This connection reinforces the need to address hypertension not just as an isolated medical condition, but as a factor that can trigger a series of interrelated health problems.

The combination of these findings highlights the importance of detecting and treating hypertension, especially in the elderly population. With such a high percentage of adults suffering from this condition, it is crucial for doctors and healthcare systems to prioritize the identification of hypertension and encourage its proper treatment.

The research suggests that the simple act of monitoring blood pressure could have significant long-term implications for brain health. Therefore, it is vital for healthcare professionals to educate their patients about the importance of monitoring their blood pressure and following treatment if necessary.

In conclusion, hypertension is not a condition to be taken lightly. With the growing knowledge about its effects on cognitive health, it is urgent that both the medical community and the general population recognize the relationship between hypertension and Alzheimer's. Prevention and treatment of this condition are crucial steps to ensure a healthier future and improved quality of life for older adults.
