Blood Pressure Linked To Brain Function
A new study now shows that blood pressure correlates with mental function. Research found that high blood pressure was associated with decreased cognitive function. For every 10-point elevation in diastolic blood pressure, the increased odds of having thinking problems by 7%.
Experts think have different theories on why blood pressure affects brain function. One idea is that the diastolic pressure is closely related to small blood vessel disease and perfusion pressure, the force that moves blood through the brain’s blood vessels. Another idea is the high rate of death among those with high systolic pressure. These deaths prevent the patients from participating in the study.
Researchers are on the way to believing that preventing high blood pressure could likely avoid brain damage or dementia. Also, controlling high blood pressure regulates hypertension, which has an influence on cognition.
