A recent study published in JAMA Network Open has shown that older adults who take medications to lower their blood pressure may have a reduced risk of developing dementia. The research pooled data from 17 observational studies that included over 34,000 adults aged 60 to 110, with an average age of 72. The participants were followed for an average of four years.
The findings suggest that untreated high blood pressure can increase the risk of dementia by 42% compared to healthy older adults. Those with untreated high blood pressure had a 26% greater risk than those with treated high blood pressure. However, when researchers compared people with treated high blood pressure to healthy older adults without high blood pressure, they found no meaningful difference in dementia risk between the two groups.
This study reinforces the connection between heart and brain health and suggests that treating high blood pressure in later life may benefit both organs. As always, it’s important to consult with a healthcare professional before making any changes to your medication regimen or lifestyle habits.
