A new study says that controlling blood pressure may be the best way to reduce risk of dementia.
This study was conducted by a team of researchers at Imperial College London, and is published in the Lancet Neurology journal.
As a part of it, researchers looked at a trial of elderly patients with high blood pressure to see if those who were being treated were less likely to develop dementia compared with those not treated.
On combining the results of this study, and other similar ones, the boffins noted that controlling blood pressure could lower the incidence of dementia by as much as 13 percent, reports the BBC.
Another study by the Alzheimer's Society, found that people who have high blood pressure in their 40s and 50s were six times more likely to develop vascular dementia.
Researchers are now urging people, even those in middle age, to have regular blood pressure and cholesterol checks.
