Treated high blood pressure lowers dementia risk

A study in JAMA Network Open suggests that older adults with treated high blood pressure have a 26% lower risk of developing dementia compared to those with untreated high blood pressure. The report analyzed 17 studies involving over 34,000 adults aged 60 to 110, finding a 42% higher dementia risk in untreated high blood pressure cases. The findings emphasize the link between heart and brain health, highlighting the potential benefits of treating high blood pressure in later life.
