At-home ‘brain quiz' reveals your risk of heart disease, stroke, dementia and 3 types of cancer
AN at-home 'brain quiz' can reveal your risk of dementia, as well stroke, heart disease and three common types of cancer.
It suggests that taking better care of your brain could boost your overall health, researchers said.
Developed at Mass General Brigham - a hospital affiliated with Harvard Medical School - the McCance Brain Care Score (BCS) is a tool designed to assess modifiable risk factors that influence brain health.
The quiz's 21 questions evaluate someone's physical health, lifestyle, as well as social and emotional factors.
All together, these can pain a picture of someone's risk of brain diseases that come on with age.
But researchers found the quiz could also shed light someone's risk of non-brain related diseases, such as heart disease or cancer.
That's because neurological diseases such as stroke, dementia, and late-life depression, as well as cardiovascular diseases —including ischaemic heart disease, stroke, and heart failure —and cancers are often driven by the same risk factors.
These include things like unhealthy diet, lack of exercise, smoking, excessive drinking, high blood pressure, cholesterol and blood sugar.
Psycho-social factors like stress and social isolation are also drivers of disease.
In fact, at least 80 per cent of cardiovascular disease cases and 50 per cent of cancer cases can be linked to these factors, researchers claimed.
Senior author Sanjula Singh, of the McCance Center for Brain Health at Massachusetts General Hospital, said: "While the McCance Brain Care Score was originally developed to address modifiable risk factors for brain diseases, we have also found it's associated with the incidence of cardiovascular disease and common cancers."
'These findings reinforce the idea that brain disease, heart disease, and cancer share common risk factors and that by taking better care of your brain, you may also be supporting the health of your heart and body as a whole simultaneously.'
10 second one leg stand test
The quiz will generate a score of 0 to 21 - the higher your score, the more brain-healthy habits you practice.
Researchers used data from the UK Biobank to analyse health outcomes in 416,370 people aged 40 to 69 years using the test.
They found that a 5-point higher BCS score at baseline was associated with a 43 per cent lower risk of developing cardiovascular disease - including ischaemic heart disease, stroke, and heart failure - over 12 and a half years.
For cancer, a 5-point increase in BCS was associated with a 31 per cent lower rate of lung, bowel and breast cancer.
How to do the quiz
Before you take the test, you'll need some information from your health records, such as your latest blood pressure reading, you haemoglobin A1c score, your cholesterol levels and BMI.
The test - available on the Mass General Brigham website - starts off by asking people about their blood pressure, cholesterol levels and BMI, as well as smoking, exercise and sleep habits.
It also asks patients about social relationships - whether they're close to anyone outside of spouses and children - and if they feel that their "life has meaning".
Once you've answered the questions, the quiz will generate a score between 0 and 21, and ways to improve your brain health.
The aim is to achieve the highest score possible.
The score will be made up of three categories – physical, lifestyle, and social-emotional health – and it measures what you are already doing to protect your brain and prolong your brain health.
This can include exercise, sleep, social interactions, lowering blood pressure and more.
"Your McCance Brian Care score is a tool you can use to measure and improve how well you care for your brain throughout your life," according to Mass General Brigham.
"Small adjustments, like finding some time to walk more in your day or making it a priority to call your best friend, can have a major improvement on your overall score and brain health over time.
"Achieving your highest score and keeping your highest score month after month, year after year, will ensure you are taking the best care of your brain as you grow and thrive."
Study authors said that previous research suggests that some individual components of the BCS quiz - such as smoking, lack of exercise and high blood pressure - can raise the risk of dementia or heart disease.
But they said that their study can't prove that the BSC components can cause disease - only that they are strongly linked.
Researchers also noted that the quiz can't be used to predict whether someone will get a specific disease.
Instead, it can serve as a framework to help people identify achievable lifestyle changes that support the health of their brain, as well as the rest of their body.
Lead author Jasper Senff said: 'The goal of the McCance Brain Care Score is to empower individuals to take small, meaningful steps toward better brain health.
'Taking better care of your brain by making progress on your Brain Care Score may also be linked to broader health benefits, including a lower likelihood of heart disease and cancer.
'Primary care providers around the world are under growing pressure to manage complex health needs within limited time," he went on.
'A simple, easy-to-use tool like the McCance Brain Care Score holds enormous promise - not only for supporting brain health, but also for helping to address modifiable risk factors for a broader range of chronic diseases in a practical, time-efficient way.'

Key RFK Jr advisers stand to profit from a new federal health initiative
Federal health officials are seeking to launch a 'bold, edgy' public service campaign to warn Americans of the dangers of ultra-processed foods in social media, transit ads, billboards and even text messages. And they potentially stand to profit off the results. Ultra-processed foods are a fixation for the US health and human services (HHS) secretary, Robert F Kennedy Jr, a vaccine skeptic who believes the US industrialized food supply is a 'primary culprit' behind many chronic diseases. 'We need to fix our food supply. And that's the number one thing,' Kennedy said at his confirmation hearing. Bringing healthier foods to Americans has proved to be one of the most resonant issues of Kennedy's 'Make America healthy again' (Maha) campaign – and arguably the only one that Democrats and Republicans agree on in principle. Kennedy has spent most of his tenure as health secretary dismantling key components of US vaccine infrastructure, instituting mass firings and defunding chronic disease prevention programs, such as for tobacco use. The secretary has been less successful in reigning in food makers. Food advocates have described voluntary changes between the government and manufacturers 'disappointing'. Kennedy was criticized by congressional Republicans for targeting agricultural pesticides in the 'Maha' report before it was even released – showing the limits of Republicans appetite for regulation, then the report itself was riddled with errors, likely generated by AI. 'The campaign's creative content will turn heads, create viral moments on social media, and – above all else – inspire Americans to take back their health through eating real food,' said a document published by the federal government that described the campaign. The campaign is expected to cost between $10m to $20m, according to documents. Anyone seeking to apply for the award will have a quick turnaround – the deadline is 26 June. 'The purpose of this requirement is to alert Americans to the role of processed foods in fueling the diabetes epidemic and other chronic diseases, inspire people to take personal responsibility for their diets, and drive measurable improvements in diabetes prevention and national health outcomes,' it continued. The new public relations campaign also highlights the Trump administration's unconventional approach to hiring – including its reliance on special government employees. A key adviser to Kennedy, Calley Means, could directly benefit from one of the campaign's stated aims: popularizing 'technology like wearables as cool, modern tools for measuring diet impact and taking control of your own health'. Calley Means is a senior Kennedy adviser, and was hired as a special government employee to focus on food policy, according to Bloomberg. He founded a company that helps Americans get such wearable devices reimbursed tax-free through health savings accounts. Casey Means is Calley's sister. She also runs a healthcare start-up, although hers sells wearable devices such as continuous glucose monitors. She is Kennedy's nominee for US surgeon general, and a healthcare entrepreneur whose business sells continuous glucose monitors – one such wearable device. Calley Means's company also works with Casey's company. Due to Calley Means's status as a special employee, he has not been forced to divest from his private business interests – a situation that has already resulted in an ethics complaint. Consumer advocates, such as the non-profit group Public Citizen, had warned such hiring practices could cause conflicts of interest. HHS did not respond to a request for comment about Calley Means's private business interests, or his role in crafting the publicity campaign. Although the publicity campaign focuses on the ultra-processed foods connection to diabetes, at least one high profile nutritionist was queasy about its focus. 'The ultra-processed foods – some of those include breakfast cereals that are ultra-processed because they are fortified with vitamins,' said Walter Willett, a professor of epidemiology and nutrition at the Harvard TH Chan School of Public Health. 'Those are good if they're whole grain breakfast cereals and whole grain breads,' he said. Ultra-processed foods are generally recognized as sodas, salty snacks and frozen meals engineered to be shelf-stable, convenient and inexpensive. Such foods are associated with increased risk of type 2 diabetes – or insulin resistance. The mechanism by which such foods could increase risk of diabetes is unknown, a problem that extends in part from the 'heterogeneous category' of foods that the ultra-processed category encompasses. The publicity campaign proposal does not venture into defining the category, even as Kennedy has fixated on it 'poisoning the American people'. 'When you say processed foods you don't envision a Coke in your brain, and that's the biggest problem,' said Willett, who added that most public service campaigns are carefully crafted and tested for effectiveness.

As a heatwave approaches, experts say US sunscreens are less effective than those abroad
Many dermatologists and experts say US sunscreens are still not as effective as many available overseas when it comes to protecting against ultraviolet radiation linked to skin cancer and premature ageing – despite years of research. The concern comes as a brutal heatwave, with a suffocating 'heat dome', is arriving for more than 200 million people across vast swaths of the US this weekend, bringing extreme heat and humidity . Studies have shown that the global climate crisis is making heatwaves more severe, frequent and long lasting. As fierce sun beats down on parts of the US this weekend, people are urged to try to stay out of the direct sun, stay hydrated and apply lots of sunscreen if outdoors – but people will probably have to rely on sunscreens that are less effective at fending off the ultraviolet rays than sunscreen available in some other countries. While American sunscreens generally do a good job at blocking UVB rays, which cause sunburn, experts and studies have noted in recent years that they often provide weaker protection against ultraviolet radiation in the form of UVA rays, compared to products available in places like Europe and South Korea. A 2017 study found only around half of US sunscreens tested met the European standards for UVA protection. Experts attribute this gap largely to regulatory differences. In the US, sunscreen is classified and regulated as an over-the-counter drug, rather than a cosmetic product like in other countries. This means that each active ingredient must undergo an often lengthy regulatory approval process with the US Food and Drug Administration (FDA) and are subject to rigorous safety requirements and animal testing. Experts often point out that the FDA has not approved a new UV-filter for sunscreen in more than 20 years. 'The issue for me isn't the safety of the sunscreens we have,' dermatologist Adewole Adamson told NPR. 'It's that some of the chemical sunscreens aren't as broad spectrum as they could be, meaning they do not block UVA as well. This could be alleviated by the FDA allowing new ingredients.' Meanwhile, in countries like France, South Korea, the UK and Japan, governments have approved a wider range of UV-filtering ingredients, which experts say allow for more advanced sunscreens. One of the ingredients is bemotrizinol, which is considered one of the safest and most vetted chemicals on the global market. It remains unapproved by the FDA, but Swiss sunscreen company, DSM-Firmenich, is seeking FDA approval for it. But, dermatologist Dr Nazanin Saedi told Axios that a decision is not expected before 2026. 'So do not delay in stocking up on your sunscreen for this summer!' she said. In a statement to the Guardian, a spokesperson for the FDA said that 'many currently marketed and widely available sunscreen products in the US provide excellent broad-spectrum coverage and are effective in preventing sunburn and reducing the risk of skin cancer and early skin aging caused by the sun, when used as directed with other sun protection measures'. 'The fact that sunscreen ingredients are available in other countries does not mean that the important safety questions about these ingredients are well understood, or that they provide greater efficacy or safety than sunscreens lawfully sold in the US,' the spokesperson added. 'In many other countries, sunscreens are regulated differently and may not be required to have the data that FDA, and other experts, consider necessary to fully evaluate the safety of sunscreen ingredients.' In 2023, representative Alexandria Ocasio-Cortez, a Democrat representing New York, spoke out about the quality of US sunscreens compared to elsewhere and urged Americans to contact their member of Congress to draw attention to this issue. 'US sunscreens are far behind the rest of the world and our regulations aren't necessarily making our sunscreens better or safer – but it doesn't have to be this way!' Ocasio-Cortez said. Republican senator Mike Lee agreed with the New York representative, and in a post on social media, wrote: 'There is no left or right when it comes to UV light.' A bipartisan bill introduced in Congress aims to modernize sunscreen regulations and allow non-animal testing alternatives for regulatory approval. Still, dermatologists stress the importance of wearing sunscreen, and Dr Robert Kirsner, a dermatologist with the Sylvester Comprehensive Cancer Center at the University of Miami, told CBS that the sunscreens available in the US are still considered safe and effective as long as they are used properly. Expert suggest wearing a broad-spectrum sunscreen with an SPF of 30 or higher and advise wearing it every day, even on cloudy days. For those seeking the safest products in the US market, experts told the Guardian last year that people should look for physical, also known as 'mineral', sunscreens containing zinc oxide and titanium dioxide.

Study pinpoints exact number of coffees per day that can cut the risk of sudden cardiac death
A coffee a day might be enough to keep the doctor away. For US researchers have found coffee lovers tend to have healthier hearts, putting them at lower risk of cardiac death. And the benefits can be achieved by drinking just one cup a day, they claimed—but only if they drink it black. Those who drank between two to three cups, however, saw the most benefits, slashing their risk by almost a fifth. The findings, from the study of more than 46,000 people, add to the growing body of evidence highlighting the drink's health benefits. Professor Fang Fang Zhang, a nutrition expert at Tufts University in Boston, said: 'Coffee is among the most-consumed beverages in the world, and with nearly half of American adults reporting drinking at least one cup per day, it's important for us to know what it might mean for health.' Some research has already linked coffee to reducing the risk of heart disease, heart failure and strokes, while other studies report it prolongs life. But medics remain divided, warning that excessive amounts of coffee—packed full of caffeine—can actually damage the heart. The new study, in The Journal of Nutrition, tracked the daily coffee consumption of 46,332 people over the age of 20. Over a follow up of 11 years, they found black coffee and coffee with low levels of added sugar and saturated fat—like milk or cream—had a 14 per cent lower risk of death compared to no coffee consumption. But one cup of black coffee a day, specifically, slashed the risk of death including cardiovascular death, by 16 per cent. Those who drank between two and three a day saw the risk lowered by 17 per cent. However, researchers noted that the benefits peaked at three cups a day. They also found that those who added high amounts of sweeteners and dairy to their coffee did not experience the same benefits. Researchers acknowledged, however, that the coffee consumption was self-reported by volunteers, so may have been underreported, limiting the findings. It was also assessed without detailing the roast used and preparation methods. NHS data shows a rise in the number of younger adults suffering from heart attacks over the past decade. The biggest increase (95 per cent) was recorded in the 25-29 year-old demographic, though as numbers of patients are low even small spikes can look dramatic Under NHS guidance, consuming more than four cups a day can increase blood pressure. Around 2million people in the UK are diagnosed with some form of heart disease, according to Government figures. But charities estimate that a further six million have undiagnosed high blood pressure—one of the leading risk factors for stroke and heart attack. Heart disease describes a range of conditions that affect the heart and blood vessels. It's often caused by fatty deposits in the arteries that can make it harder for blood and oxygen to flow properly through the vessels and to and from the heart. This increases the risk of a blockage, and therefore stroke or heart attack. Last year, alarming data revealed that premature deaths from cardiovascular problems, such as heart attacks and strokes, had hit their highest level in more than a decade. MailOnline has previously highlighted how the number of young people, under 40, in England being treated for heart attacks by the NHS is on the rise. Cases of heart attacks, heart failure and strokes among the under-75s has tumbled since the 1960s thanks to plummeting smoking rates, advanced surgical techniques and breakthroughs such as stents and statins. But now, rising obesity rates, and its catalogue of associated health problems such as high blood pressure and diabetes, are thought to be one of the major contributing factors.
