Does pulse analysis predict dementia?


A five-minute neck diagnosis may predict the risk of developing dementia for ten years before the onset of symptoms. It sounds incredible, but the test that analyzes blood vessels in the neck may ultimately become a standard practice if the relationship between cardiovascular disease and cognitive decline is confirmed by the scientific community.

This relationship is currently being examined by scientists from the University College of London, which presents its results during this year's American Heart Association conference. This study, which began in 2002 and examined 3191 male and female blood vessels by ultrasound scanners, was met with cautious optimism by medical organizations. Because of this!

The heartbeat sends physical impulses to all parts of the body, including the brain. The blood vessels in the neck area that are still healthy help reduce these physical impulses. However, with the adhesion of the veins, starting to lose their elasticity and protective properties, it allows the more powerful impulses to have a negative effect on the more sensitive 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 representing about 25% of the respondents had 50% more cognitive deficits in their later lives. Scientists plan to continue using magnetic resonance tomography to learn more about how blood flow interacts with dementia development. Simultaneously, if more extensive experiments confirm the results, the method will receive adequate support and this will be an indispensable part of the dementia prognosis.

Dementia is a result of memory impairment, language skills, and thought processes for years, so that the moment when a person is diagnosed is considered too late. That is why the scientific community actively works to identify this situation as early as possible.
