Impulse analysis predict dementia?


Five-minute neck diagnosis can predict the risk of dementia for one decade before symptoms occur. It sounds incredible, but the test that looks at blood vessels in the throat can eventually become a standard practice if the relationship between cardiovascular disease and cognitive decline is verified by the scientific community.

This relationship is currently being studied by London University College scientists who presented their results at this year's American Heart Association conference. The study, which began in 2002 and examined 3191 male and female blood vessels by ultrasound scanners, was greeted with cautious optimism by medical organizations. Here's why!

The battle of the heart sends physical impulses through all parts of the body, including the brain. The blood vessels in the neck area, which are still healthy, help reduce these physical impulses. But, with the hanging of the vessels, they begin to lose their elasticity and protective properties, allowing stronger impulses to have a negative effect on the more delicate blood vessels in the brain. As a result, a person is threatened by a decrease in cognitive functions.

After a routine scan of patients for 15 years, the team found that those with the strongest impulses, representing about 25% of the subjects surveyed, were 50% more likely to have cognitive deficits later in life. Scientists intend to continue using magnetic resonance tomography to learn more about how blood flow interacts with the development of dementia. Concomitantly, if larger experiments validate results, the method will receive sufficient support, making it an indispensable part of dementia prognosis.

Dementia is the ultimate result of decades of memory disorders, language skills and thought processes so that the moment of diagnosing a person is considered too late. This is why the scientific community is actively working to identify the condition as soon as possible.
