According to an article in HealthDay News, “High blood pressure may predict dementia in older adults with impaired executive function.” Someone who has impaired executive function has trouble organizing their thoughts and making decisions. This study, out of the University of Western Ontario in Canada, compared people with impaired executive function and people with memory issues.

The study looked at 990 people with an average age of 83 who did not have dementia. The participants were followed for five years. Over the five years, dementia developed in 59.5 percent of people with high blood pressure and in 64.2 percent of people without high blood pressure.

In people who just had impaired executive function, the results were different. 57.7 percent of people with impaired executive function and high blood pressure developed dementia compared with only 28 percent who did not have high blood pressure.

These findings are important because high blood pressure, also known as hypertension, can be controlled and treated.
