A five-minute ultrasound test can be used to detect people at risk for dementia before the symptoms appear.
This is the conclusion of a study that badyzed the blood vessels of the cervix.
They found that those with the most intense heartbeats at the start of the study were the ones who experienced the greatest cognitive decline in the next decade.
The researchers hope their findings will lead to a new way of detecting cognitive deterioration that leads to dementia

The study, conducted by an international team of experts and led by the University of London (UCL) measured the pulse of vessels carrying blood to the brain
When the heart beats, it generates a physical "impulse" that travels through the body with an undulatory effect.
When the heart beats, it generates a physical "impulse" that travels the body with a wave effect
The vessels located near the heart, when they are elastic and in good condition health often decrease the energy of this impulse to prevent it from reaching more delicate vessels in the body.
But factors such as aging and high blood pressure can harden these cases and decrease this protective effect.
A progressively more powerful pulse can move to the fragile vessels that feed the body.
And this, over time, could cause structural changes in the brain that may contribute to the development of dementia.
Deficiency
The team of researchers measured the pulse in the vessels 3191 persons in 2002.
Over the next 15 years, the researchers performed memory tests and their ability to solve participants' problems.
[1945] 19659003] An increasingly strong impulse can travel in the fragile blood vessels that feed the brain.
Scientists found that those with the most intense impulse (25% of participants) at the start of the study had 50% more risk to present an accelerated cognitive impairment over the next decade compared to the rest of the participants.
According to the researchers, it is the equivalent. additional deterioration lens of nearly a year or a year and a half.
Cognitive disorders are often one of the first signs of dementia although all those who suffer from it develop the disease.
] Treatments and Interventions
Researchers say the test could offer a new way of identifying people at risk of developing dementia, which could lead to earlier treatments .

Dr. Scott Chiesa, one of the researchers at UCL, said, "Dementia is the final result of decades of damage too, by the time a person is already suffering from dementia it is too late to do anything. "
" What we are trying to say is that you have to intervene as early as possible, find a way to see who is actually moving towards the possibility of having dementia and focusing on it. "[19659003] The study, co-funded by the British Heart Foundation, does not contain data on the number of people who developed dementia.
Researchers are now considering using magnetic resonance imaging (MRI) scans to determine if participants also showed structural and functional changes in the brain that could explain their cognitive decline.
They also tried to check if the scanners improved the prediction scores. Assessing the risk of existing dementia
Dr. Carol Routledge, Research Director at the Alzheimer's & Research UK Organization, states that still needs to be confirmed if an ultrasound can improve the diagnosis of dementia.
What we do know is that blood circulation in the brain is extremely important and maintaining a healthy heart and blood pressure is badociated with a lower risk of developing dementia. " he declared. (I)
