Dmytro Zinkevych/Shutterstock Hormone therapy is widely used to treat menopausal symptoms such as hot flushes and night sweats. But scientists have long debated whether it affects dementia risk. A new study adds another piece to this puzzle. It suggests that an Alzheimer’s biomarker may help identify which women are more vulnerable to dementia with certain […]

Angel Gruber/Shutterstock Air pollution has long been linked to heart and lung disease. But a large US study suggests it may also raise the risk of Alzheimer’s disease – the most common form of dementia. Researchers tracked nearly 28 million older adults over six years nationwide. They found that those exposed to higher levels of […]

Barillo_Images/Shutterstock.com Scientists have found that drinking two to three cups of coffee a day may significantly reduce your risk of developing dementia, but drinking more won’t help protect your brain any further. A major study tracked 131,821 American nurses and health professionals for up to 43 years, starting when they were in their early 40s. […]

CandyRetriever/Shutterstock We may not need to completely overhaul our lives to live healthier for longer, according to a large UK-based study. This is welcome news, particularly as many people will already have abandoned their New Year’s resolutions. The recent study followed around 590,000 people in the UK, with an average age of 64, over an […]

photolin/Shutterstock A large Swedish study reported a lower risk of dementia among middle-aged and older adults who consumed higher amounts of full-fat cheese and cream. The findings may sound like welcome news but they need careful interpretation. The study followed 27,670 participants for 25 years, during which 3,208 developed dementia. Among people without a known […]

A new study suggests that even low levels of physical activity could protect the brain from Alzheimer’s disease – but not in the way scientists expected. The researchers tracked almost 300 older adults with early brain signs of Alzheimer’s for nine to 11 years using pedometers. They found that physical activity didn’t reduce the toxic […]

More and more research suggests that the copper in your diet could play a bigger role in brain health than we once believed. A recent study found that older Americans who ate more copper-rich foods did better on memory and concentration tests. The findings, published in Nature Scientific Reports, looked at people’s diets using detailed […]
