Postponed retirement slows cognitive decline
*Participating in the labor market until the age of 67 slows cognitive decline and is protective against cognitive impairment, study indicates* Participating in the labor market until the age of 67 slows cognitive decline and is protective against cognitive impairment, such as that caused by Alzheimer’s. This protective effect appears to hold regardless of gender and educational or occupational attainment. These findings were recently published in the journal *SSM Population Health.* The team of researchers with Jo Mhairi Hale, Maarten J.

[image: Social Support and Cognitive Performance] CAPTION Higher social listener availability slowed cognitive decline even as brain volume decreased. CREDIT NYU Langone Health Supportive social interactions in adulthood are important for your ability to stave off cognitive decline despite brain aging or neuropathological changes such as those present in Alzheimer’s disease, a new study finds. In the study publishing August 16 in *JAMA Network Open*, researchers observed that simply having someone available most or all of the time whom you can count on to listen to you when ... read more
Mentally stimulating jobs linked to lower risk of dementia in old age
People with mentally stimulating jobs have a lower risk of dementia in old age than those with non-stimulating jobs, finds a study published by *The BMJ* today. One possible explanation is that mental stimulation is linked to lower levels of certain proteins that may prevent brain cells forming new connections (processes called axonogenesis and synaptogenesis). Cognitive stimulation is assumed to prevent or postpone the onset of dementia. But trial results have varied and most recent long term studies have suggested that leisure time cognitive activity does not reduce risk of d... read more

Key mental abilities can actually improve during aging
It’s long been believed that advancing age leads to broad declines in our mental abilities. Now new research from Georgetown University Medical Center offers surprisingly good news by countering this view. The findings, published August 19, 2021, in *Nature Human Behaviour*, show that two key brain functions, which allow us to attend to new information and to focus on what’s important in a given situation, can in fact improve in older individuals. These functions underlie critical aspects of cognition such as memory, decision making, and self-control, and even navigation, math, ... read more

Lack of exercise and poor nutrition could increase the risk of diseases like dementia
New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London has found that both diet and exercise can influence the risk of cognitive decline (CD) and dementia by potentially influencing hippocampal neurogenesis (the process by which the brain produces new brain cells) long before their onset. The study, published in *Alzheimer's & Dementia*: The Journal of the Alzheimer's Association, suggests that altered neurogenesis in the brain could potentially represent an early biomarker for both CD and dementia.

Isometric resistance training effectivesin reducing office blood pressure
When was the last time you had your blood pressure checked? High blood pressure affects 1.13 billion people around the globe and in 2019, it accounted for 10.8 million deaths. Worldwide, it’s the leading risk factor for mortality. More than a third of the Australian population over the age of 18 has high blood pressure, yet it’s estimated 50 per cent of Australians don’t realise they’re living with it. As high blood pressure puts you at high risk of having a heart attack or stroke (cardiovascular disease), it’s important to keep track of your blood pressure. People over the age o... read more

Antacid famotidine improves the odds of survival for COVID-19 patients, especially when it is combined with aspirin
In the early days of the COVID-19 pandemic, doctors in Wuhan noticed something surprising. Many of the elderly patients who survived the virus were poor: not exactly the demographic you would expect to fare well in a health crisis. A review of the survivors’ medical records revealed that a significant number suffered from chronic heartburn and were taking an inexpensive drug called famotidine, the key ingredient in Pepcid. (Wealthier patients tended to take the more costly drug omeprazole, found in Prilosec.) Was an over-the-counter acid suppressant helping people survive COVID... read more

Mediterranean diet shows promise in men with erectile dysfunction
A Mediterranean diet is associated with improvements in erectile dysfunction, according to research presented at ESC Congress 2021.1 Men with hypertension are twice as likely to have erectile dysfunction as their peers with normal blood pressure.2 Erectile dysfunction is primarily considered a disorder of the small arteries, which lose the ability to dilate and augment flow. Declining testosterone levels in middle age contribute to its onset. Previous research has shown that fitness is linked with improved survival in men with hypertension,3 while the Mediterranean diet lowers bl... read more

It found that substituting 10% of daily caloric intake from beef and processed meats for a mix of fruits, vegetables, nuts, legumes and select seafood could reduce your dietary carbon footprint by one-... read more
New study disproves “fast carbs make you fat” claim
A study recently published in *Advances in Nutrition*, a peer-reviewed nutrition journal from the American Society for Nutrition, concludes that high-glycemic (high-GI) foods (often called “fast carbs”) are no more likely than low-GI foods (often called “slow carbs”) to lead to weight gain – and no less likely to lead to diet-induced weight loss. Undertaken to assess the hypothesis that high-GI foods promote fat storage and increase risk of obesity by causing a rapid increase in blood sugar and insulin secretion, and that low-GI foods do the opposite, the comprehensive study ana... read more
People who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease
New Edith Cowan University (ECU) research has found that people who eat a diet rich in vitamin K have up to a 34 percent lower risk of atherosclerosis-related cardiovascular disease (conditions affecting the heart or blood vessels). Researchers examined data from more than 50,000 people taking part in the Danish Diet, Cancer, and Health study over a 23-year period. They investigated whether people who ate more foods containing vitamin K had a lower risk of cardiovascular disease related to atherosclerosis (plaque build-up in the arteries). There are two types of vitamin K found ... read more
Low glycemic diet shows meaningful improvements for people with diabetes
For people with diabetes, sticking to a low glycemic diet results in small but important improvements in blood sugar levels, cholesterol, weight and other risk factors, finds a study published by *The BMJ* today.

People who most strongly agreed with this belief not only enjoyed leisure less, but also reported poorer mental health outcomes, said Selin Malkoc, co-author of the study and associate professo... read more
