The Heart Health Issue That Can Contribute to Dementia Risk
An August 2024 study in Neurology analyzed information from 14 studies that looked at a total of 31,250 participants from all around the world. The average participant was 72 years old. This study found that people with untreated high blood pressure had a 36 percent higher risk for Alzheimer’s than those without high blood pressure and a 42 percent higher risk than those with treated high blood pressure.
Also known as hypertension, this issue can cause a host of problems, but again, is treatable. “High blood pressure is a leading cause of stroke and cerebrovascular disease, and yet it can be controlled with medication, reducing a person’s risk of these diseases,” lead author Dr. Matthew J. Lennon, MD, PhD , of the University of New South Wales in Australia said in a press release .
