Neck scan could identify early symptoms of dementia in 5 minutes

British Heart Foundation | November 2018 | Neck scan predicts cognitive decline decade in advance

A research team lead by University College London (UCL) Professor John Deanfield, followed over 3000 participants over a fifteen-year period (3,191) middle-aged volunteers, who were given ultrasound in 2002 to measure the intensity of the pulse travelling towards their brain. Over the next 15 years, researchers monitored the participants memory and problem-solving ability.

According to the research a five minute scan of blood vessels in the neck during mid-life predicts cognitive decline a decade before symptoms appear, according to new research  co-funded by The British Heart Foundation. The findings were presented recently at the American Heart Association’s AHA Scientific Sessions conference in Chicago.

The study’s findings would need confirming in larger stuides, but the scan could potentially be used n future to help doctors identify patients who might be at high risk of developing dementia earlier than  previously possible. 

Those participants with the highest intensity pulse (top quarter) at the outset of the study were  approximately 50 per cent  more likely to exhibit accelerated cognitive decline during the next ten years when compared to the rest of the participant cohort. The researchers controlled factors which might also contribute to cognitive decline, like age, BMI, blood pressure and diabetes.

One of the researchers, Dr Scott Chiesa from UCL commented on their findings:

“These findings demonstrate the first direct link between the intensity of the pulse transmitted towards the brain with every heartbeat and future impairments in cognitive function.”

“It’s therefore an easily measurable and potentially treatable cause of cognitive decline in middle aged adults which can be spotted well in advance.” (Source: British Heart Foundation)
