Properly treated hypertension reduces the risk of dementia

A large Chinese long-term study involving nearly 34,000 people has shown that effectively treating high blood pressure reduces the risk of dementia. The research was presented at the European Society of Cardiology Congress in Munich. High blood pressure is known to damage blood vessels throughout the body, including in the brain, which can impair cerebral circulation over time. This study suggests that consistent treatment of hypertension could protect against cognitive decline. Participants were divided into two groups: one received standard care, while the other was more intensively managed by non-medical health workers to achieve specific blood pressure targets. After seven years of follow-up, those in the intensive group saw significantly lower blood pressure levels compared to the control group.

A long-term study conducted in rural areas of China has found that sustained blood pressure control significantly reduces the risk of dementia. The research, presented at the European Society of Cardiology (ESC) congress in Munich last weekend, involved nearly 34,000 participants from 326 villages. According to findings shared by Yingxian Sun, head of the Chinese Rural Hypertension Control Program (CRHCP) at the First University Hospital of China Medical University in Shenyang, individuals with consistently well-managed hypertension had a 15 percent lower risk of developing dementia compared to those who received standard care. The study followed two groups over seven years, with four years of active intervention and three years of observation. One group received standard treatment for hypertension, while the other was managed through intensified support from non-doctor health workers aiming to achieve specific blood pressure targets. These targets were set at less than 130 mmHg for systolic (upper value) and less than 80 mmHg for diastolic (lower value) readings. Participants averaged 63 years of age, with 61 percent being women. At the end of the study period, the intervention group showed a much greater reduction in blood pressure compared to the control group. On average, their systolic blood pressure dropped by 17.6 mmHg, whereas the control group’s decreased by just 2.4 mmHg. This substantial difference highlights the effectiveness of structured, community-based management of hypertension. The results indicated that the intervention group had a 15 percent lower risk of dementia, 8.85 percent versus 10.55 percent in the control group. Additionally, cognitive impairment without dementia was reduced by 13 percent among those receiving intensive care. The study also noted fewer serious adverse events in the intervention group, with 47.15 percent of patients experiencing such issues compared to 49.78 percent in the control group. These outcomes suggest that proactive, accessible healthcare models can play a crucial role in preventing neurodegenerative diseases. Dr. Sun emphasized that this approach, led by non-medical personnel, not only improved blood pressure control but also contributed to lowering dementia risk. He concluded that these findings support integrating structured blood pressure management into routine primary care to prevent dementia on a population level. Global estimates indicate that the number of people living with dementia will rise from 57 million cases in 2019 to 153 million by 2050. With no curative treatments available, prevention strategies have become increasingly vital in public health efforts. The success of this rural-based initiative underscores the potential of community-driven interventions in addressing chronic conditions linked to cognitive decline. As the world grapples with aging populations and rising rates of neurodegenerative disorders, such studies offer valuable insights into how early, consistent medical attention can mitigate long-term risks.

Long-term control of blood pressure reduces the risk of dementia

A Chinese study presented at the European Cardiology Congress in Munich found that long-term management of high blood pressure reduces the risk of dementia by 15 percent. The study involved nearly 34,000 people from 326 rural villages, comparing those who received standard care with those who were intensively managed by non-doctor health workers to achieve specific blood pressure targets. After seven years, the intervention group showed significantly lower blood pressure and a reduced risk of dementia compared to the control group. The findings suggest that integrating structured blood pressure management into routine primary care could help prevent dementia on a population level.
