It had previously been suggested that the brain is a target for damage from heart disease.
The risk factors leading to heart disease have also been associated with both vascular and Alzheimer’s dementia.
However, the mechanisms by which these associations occur are not well understood, and there had been no studies in large groups of people or those without disease.
The new research led by Queen Mary University of London and the Radcliffe Department of Medicine at University of Oxford examined links between heart health and cognitive function in over 32,000 UK Biobank participants.
The team assessed heart health using measures of anatomy and function obtained from MRI scans.

People with healthier heart structure and function appear to have better cognitive abilities, including increased capacity to solve logic problems and faster reaction times, according to research led by Queen Mary University of London and the Radcliffe Department of Medicine at University of Oxford.
Dr Zahra Raisi-Estabragh, BHF Clinical Research Training Fellow at Queen Mary University of London said: Heart disease and dementia are important and growing public health problems, particularly in ageing populations. We already knew that patients with heart disease were more likely to have dementia, and vice versa, but we ve now shown that these links between heart and brain health are also present in healthy people. We demonstrated for the first time, in a very large group of healthy people, that individuals with healthier heart structure and function have better cognitive performance.

LONDON â Not many former British prime ministers adapt easily to life after 10 Downing St. or gain the respect afforded to some ex-leaders around the world.
But few have fallen as far and as fast as David Cameron, who Thursday made his first public appearance since a lobbying scandal cast a harsh light on his character and judgment, as well as the shifting morals of British public life.
Scotland is seeing a “loss of control” of the pandemic in some areas and it is premature to lift restrictions, an epidemiologist has warned.
Dr Deepti Gurdasani said action must be taken to prevent the situation worsening amid concerns about the spread of one of the new Indian variants of the virus north of the border.
Public health experts have warned that a spike in coronavirus infections in Glasgow could include the so-called B.1.617.2 variant.
First Minister Nicola Sturgeon has said the situation in Glasgow is being monitored “very closely”, with cases in the city at 70.9 per 100,000 people in the seven days to May 10, according to latest data on Thursday.
