“The findings are important because high blood pressure and cognitive decline are two of the most common conditions associated with aging, and more people are living longer worldwide,” said Dr. L.H. Lumey, professor of epidemiology at Columbia Mailman and senior author.

High blood pressure was defined as having a systolic blood pressure of 140 mmHg or higher and a diastolic blood pressure of 90 mmHg or higher, and/or taking antihypertensive treatment.

Participants were interviewed at home about their high blood pressure treatment, education, and noted if they lived in a rural or urban environment. They were also asked to perform cognitive tests. Among the findings:
