High blood pressure appears to accelerate cognitive decline among middle-aged and older adults, but treating the condition may slow this down, according to a study unveiled Monday.

“The findings are important because high blood pressure and cognitive decline are two of the most common conditions associated with ageing, and more people are living longer, worldwide,” said L H Lumey, a professor at Columbia University in the US.

According to the American Heart Association’s 2017 Hypertension Guidelines, high blood pressure affects about 80 million US adults and one billion people globally.

Moreover, the relationship between brain health and high blood pressure is a growing interest as researchers examine how elevated blood pressure affects the brain’s blood vessels, which in turn, may impact memory, language, and thinking skills.

The researchers analysed data collected on nearly 11,000 adults from the China Health and Retirement Longitudinal Study (CHARLS) between 2011-2015, to assess how high blood pressure and its treatment may influence cognitive decline.

High blood pressure was defined as having a systolic blood pressure of 140 millimetres of mercury (mmHg) or higher and a diastolic blood pressure of 90 mmHg or higher.

For the study in China, researchers interviewed study participants at home about their high blood pressure treatment, education level and noted if they lived in a rural or urban environment. They were also asked to perform cognitive tests, such as immediately recalling words as part of a memory quiz. Overall cognition scores declined over the four-year study.
