High blood pressure, aka hypertension synonymous with heart disease. But a
new study has revealed that hypertension, especially in the arteries that supply
blood to the head and neck may be associated with cognitive decline, brain.
The research team from Australia said that people with high blood pressure in the artery or central veins, including the aorta and carotid arteries (the vessels that supply blood to the neck and head) has a test score lower visual processing, including slower thinking speed aka slow and
recognition ability (recognize something) worse.
"Usually the blood pressure measurements taken from brachial artery in the arm, but it turns out to observe the condition of the central artery may be a more sensitive way to assess a person's cognitive abilities. Central controls Because arterial blood flow to the brain directly," said researcher Matthew Pase of the Center for Human Psychopharmacology, Swinburne University, Melbourne.
"So if we can estimate the blood pressure in the central artery, then we can predict cognitive function and cognitive decline that may occur in a person," he added.
In the study, Pase and his colleagues looked at which of the blood pressure measurements from the arm or from a central artery that has a strong connection with the person's cognitive abilities.
In this case the researchers recruited 493 participants aged 20-82 years from Australia.
Most researchers are Caucasians and non-smokers with no history of stroke or dementia.
Then participants were asked to perform a number of tasks to measure their cognitive abilities such as visual processing, memory, recognition ability (recognize something) and information processing speed.
Not forgetting the researchers also measured the participants' blood pressure both arms and a central artery.
As a result, high blood pressure in the brachial artery is associated with performance on tests of visual processing is worse. But high blood pressure in the central artery is associated with a poor performer on other cognitive tests, including visual processing, recognition and information processing speed.
"This shows that central blood pressure is a more sensitive predictor of aging-related cognitive," Pase node as reported by FoxNews, Friday (31/05/2013).
Pase suspect someone with age then tightened and the main arterial elasticity decreases, the brain receives more blood high pressure, which in turn can damage the brain's cognitive abilities.
The study will be published in the journal Psychological Science.
