Reacción a "Lowering high blood pressure reduces the risk of dementia"

This large trial of over 33,000 people in rural China provides further evidence that addressing high blood pressure could be one way to reduce dementia risk. This is consistent with a landmark report published in The Lancet last year, which highlighted untreated high blood pressure as one of 14 risk factors that account for almost half of global dementia cases. Existing medicines and lifestyle changes to reduce blood pressure could present a more accessible way to lower dementia risk for those with high blood pressure.

While the results from this trial are reassuring, further studies are needed to understand how other risk factors like genetics interact with factors like high blood pressure to influence dementia risk. It will also be interesting to see whether interventions trialed in this study can work in other populations across the world. 

Looking after our heart and blood vessel health is something we can all do to improve our overall wellbeing and reduce our risk of dementia. With no current treatments available on the NHS to slow or stop the diseases that cause dementia, there has never been a more pressing need to promote good brain health and to gain a deeper understanding of how we can reduce our risk of developing dementia.

The government also has a vital role to play in tackling the health and lifestyle factors that influence dementia risk – including cardiovascular health. This could mean introducing policies to reduce salt, sugar, and calories in processed foods, and lowering the NHS Health Check eligibility age in England from 40 to 30, so more people can start managing their blood pressure earlier in life.

If you’re worried about your blood pressure, or haven’t had it checked for a while, speak to your GP or your local pharmacy may offer this service. If you’re over 40, you should ideally have your blood pressure checked at least every five years.
