A new study published in JAMA Network Open on Sept. 5, 2023, has found that older adults who take medications to lower their blood pressure may reduce their risk of dementia. The report combined data from 17 separate observational studies, which included over 34,000 adults aged 60 to 110.
The findings of the study showed that people with untreated high blood pressure were 42% more likely to develop dementia compared to healthy older adults. Those who were untreated had a 26% greater risk than people with treated high blood pressure. Additionally, 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. These findings reinforce the connection between heart and brain health and suggest that treating high blood pressure in later life may benefit both organs.
It’s important for readers to note that while this study provides valuable insights into the relationship between blood pressure and dementia risk, it should not be used as a substitute for direct medical advice from a doctor or other qualified clinician. It’s always best to consult with a healthcare professional before making any changes to your medication or treatment plan.
