New research has highlighted the potential of reducing high blood pressure and making dietary changes in decreasing the risk of developing dementia. A study from the University of Texas, involving 34,000 individuals with high blood pressure in rural China, emphasized how lifestyle modifications and proper medication can influence blood pressure levels. Over a four-year period, participants were carefully monitored to analyze the effects.
One group received intensive interventions for blood pressure, which included medication, health coaching, and advice on reducing alcohol and salt consumption. The other group received standard medical care, with basic guidance on managing blood pressure.
The results showed that those in the intensive blood pressure management group had a 15% lower risk of developing dementia and a 16% reduced likelihood of experiencing cognitive impairment, such as memory and thinking problems.

With approximately 982,000 people in the UK currently living with dementia, a figure projected to rise to 1.4 million by 2040, these findings hold significance. Dr. Richard Oakley, associate director of research and Innovation at Alzheimer’s Society, expressed optimism about the study’s potential impact. He emphasized the link between heart health and brain health and stressed the need for further research to explore the long-term benefits of blood pressure control.
The NHS advises that high blood pressure, coupled with factors such as poor diet, smoking, and excessive alcohol consumption, can increase dementia risk. The study also underlines the potential impact of reducing salt and alcohol intake in managing dementia risk, alongside interventions for blood pressure control.
Nevertheless, while the research is promising, ongoing evaluation is necessary to determine the lasting impact and potential implications for broader populations with limited resources. The research, published in the journal Nature Medicine, carries potential implications for the future of dementia prevention and care.
