A recent study published in Nature Medicine indicates that treating high blood pressure can significantly lower the risk of developing dementia. The clinical trial showed that after four years of intensive blood pressure management, participants experienced a 15% reduction in dementia risk and a 16% reduction in mild cognitive impairment. The study involved nearly 34,000 individuals in rural China, emphasizing the importance of controlling hypertension to prevent cognitive decline. This evidence reinforces the link between hypertension and dementia and supports the use of antihypertensive medications as a preventative measure.
Our study shows that dementia is preventable, says Jiang He, a physician who studies epidemiology, internal medicine and neurology at the University of Texas Southwestern Medical Center.
After four years, 4.6 percent of those who underwent intensive blood pressure control were diagnosed with dementia compared with 5.4 percent in the group that received standard care.
