New Study Links Blood Pressure Variability to Cognitive Decline in Older Adults

A recent study published in Neurology by the American Academy of Neurology indicates that fluctuating blood pressure may accelerate cognitive aging, particularly in Black older adults, SciTech Daily reported.

Researchers analyzed data from 4,770 participants, averaging 71 years old, and found that those with the highest variability in systolic blood pressure exhibited cognitive test scores equivalent to nearly three years of aging.

Notably, this association was not observed in white participants or those on blood pressure medication. The study revealed that Black participants had an average blood pressure variation of 18 mmHg, compared to 16 mmHg for white participants.

Dr. Anisa Dhana emphasized the importance of monitoring blood pressure fluctuations to identify individuals at risk for cognitive issues. While the study highlights a correlation, it does not establish a cause-and-effect relationship. The findings underscore the need for effective prevention strategies as the population ages and Alzheimer’s disease prevalence rises.
