Raised Blood Pressure at Any Age Speeds Cognitive Decline

Here is a reminder that the increased blood pressure of hypertension, or even more modestly raised blood pressure, is an important downstream mechanism in aging. Higher blood pressure over time results in greater tissue damage to the brain, kidneys, and other organs, greater vulnerability to atherosclerosis, and many more issues. Raised blood pressure is one of the more important ways in which the underlying molecular damage of aging is converted into structural and physical damage that leads to death. High blood pressure appears to accelerate a decline in cognitive performance in middle-aged and older adults. Nearly half of American adults have high blood pressure or hypertension. Having high blood pressure is a risk factor for cognitive decline, which includes such things as memory, verbal fluency, attention and concentration. Blood pressure of 120 mmHg - 129 mmHg systolic (the top number in a reading) or higher is considered elevated. Systolic pressure above 130 mmHg, or diastolic pressure (the bottom number) of 80 mmHg or higher is considered hypertension. Researchers analyzed findings from an existing study that included blood pressure and cognitive health information for more than 7,000 adults in Brazil, whose average age was about 59 years old at the study's start. The study participants were followed for an average of nearly 4 years; testing included analysis of memory, verbal fluency, and executive function, which includes attention, concentration, an...
