Dementia, a neurodegenerative disease that causes progressive deterioration of nerve cells, can be prevented in older people through the treatment of high blood pressure, according to a recent study.
High blood pressure, also known as hypertension, is a common risk factor for dementia. However, the study shows that the risk can be significantly reduced if hypertension is properly treated.
The research, led by Matthew J. Lennon from the University of New South Wales in Sydney, focused on investigating the correlation between high blood pressure and dementia in older individuals. For the study, the medical records of approximately 34,500 people above 60 years of age from 17 different cohort studies were analyzed.
The participants were categorized into three groups: those who were treated for high blood pressure, those with untreated hypertension, and a control group of healthy individuals. The study included participants from 15 different countries, including Germany.
The results revealed that individuals with untreated hypertension had a 42 percent higher risk of developing dementia compared to the healthy controls. On the other hand, individuals with treated high blood pressure showed only a 26 percent increased risk compared to the healthy group. This suggests that consistent high-pressure therapy throughout old age plays a crucial role in preventing dementia.
In addition to these findings, the study emphasizes the importance of early intervention and treatment of high blood pressure in middle-aged individuals. Previous research has indicated that high blood pressure in middle age is associated with a nearly 60 percent increased risk of dementia.
The study’s results highlight the significance of managing hypertension not only for cardiovascular health but also for brain health. By reducing high blood pressure, individuals can potentially lower their risk of developing dementia.

Overall, the study sheds light on the significant role that hypertension treatment plays in dementia prevention, particularly in older individuals. Further research and awareness in this area can contribute to improving the quality of life for older adults and reducing the burden of dementia worldwide.]
