Five minutes of neck diagnosis can predict the risk of developing dementia for a decade before beginning symptoms. This sounds unbelievable, but the test that analyzes the blood vessels in the neck may end up being a standard practice if the relationship between cardiovascular disease and cognitive decline is verified by the scientific community.

This relationship is now being studied by scientists at the University of London, who presented their results during the American Heart Association conference this year. The study, which began in 2002 and during which 3191 blood vessels were examined by men and women by ultrasound scanners, was received with cautious optimism by medical organizations. Here's why!
The beatings of the heart send physical impulses throughout the body, including the brain. The blood vessels in the neck area, which are still healthy, help to reduce the physical impulses. But with the clinging of the vessels, they begin to lose their flexibility and protective properties, allowing stronger impulses to have a negative effect on the finer blood vessels in the brain. As a result, a person is threatened by a decline in cognitive functions.
After a routine screening of patients for 15 years, the team found that those with the strongest impulses, about 25% of those surveyed, had a 50% higher risk of cognitive deficits later in life. Scientists plan to continue using magnetic resonance tomography to learn more about how blood flow interacts with the development of dementia. However, if more extensive trials validate the results, the method will receive enough support, making it an essential part of the dementia exercise prognosis.
Dementia is the end result of decades of memory impairment, language abilities and thought processes, so that once the person has been diagnosed it is considered too late. That is why the scientific community is actively working towards identifying the situation as early as possible.
