Dementia risk drops 25% with one daily habit change

More than 55 million people worldwide are living with dementia, and researchers still have no definitive cure. What they do have is a growing body of evidence pointing to lifestyle habits that meaningfully shift the odds. A study published in the journal PLOS One, which analyzed data from 69 separate studies involving adults aged 35 […]
Is sedentary lifestyle quietly damaging your brain

Wrinkles, slower recall, a little more fatigue than you used to feel aging touches everything. But while some of that is unavoidable, scientists are increasingly clear that how fast it happens is something people have more control over than they might realize. Genetics, sleep quality, diet, cardiovascular health, social connection, and lifestyle choices all shape […]
Menopause may be triggering Alzheimer’s in women far earlier than doctors ever suspected

Menopause has long been understood as a reproductive transition. What it does to the brain has received far less attention. A new expert review published in The Journal of Clinical Investigation is working to change that, making the case that the hormonal upheaval of menopause may represent one of the most significant and underappreciated risk […]
How your gut bacteria may protect your brain as you age

For a long time, the idea that the bacteria living in your digestive tract could have anything to do with memory, focus, or the risk of dementia seemed far-fetched. Now, a growing body of science says otherwise and a major new review is adding significant weight to that conversation. Published in Nutrition Research, the review […]
Gut microbiome interventions are proving surprisingly effective at preserving memory

Gut health has spent years on the periphery of serious medical conversation, associated more with digestive discomfort than with anything as consequential as memory or mental sharpness. That is changing fast. A growing body of research is drawing an increasingly clear line between the health of the gut microbiome and the trajectory of cognitive decline […]
New study finds APOE4 carriers who eat more meat show significantly less cognitive decline

A new observational study published in JAMA Network Open has found that people carrying the APOE4 genetic variant, the strongest known genetic risk factor for Alzheimer’s disease, may experience slower cognitive decline when they eat higher amounts of meat. The finding does not apply broadly to the general population and the researchers are careful to […]
Brain health researchers approve mentally active sitting

A study published in the American Journal of Preventive Medicine analyzed health data from more than 20,000 adult brain between the ages of 35 and 64, focusing on how different types of sedentary behavior relate to dementia risk. The research drew a distinction between two categories of sitting: mentally passive activities that require little cognitive […]
What poor sleep does to your focus and performance

Most people have convinced themselves that running on five hours of sleep is manageable. They grab a coffee, push through the morning fog, and tell themselves they will catch up on rest over the weekend. But the science tells a very different story — and the damage being done in the meantime is far more […]
AI tool finds Alzheimer’s warning signs with 93% accuracy

Alzheimer’s disease has long outpaced the tools designed to catch it. By the time most people receive a diagnosis, the disease has already been quietly reshaping the brain for years. A new study published in the journal Neuroscience suggests that artificial intelligence may be on the verge of changing that reality, giving clinicians a powerful […]
Sleep apnea is silently driving 5 major health conditions in millions of undiagnosed adults

Sleep apnea is the condition that affects an estimated 30 million American adults and has been formally diagnosed in approximately 6 million of them. That gap between prevalence and diagnosis is not a minor administrative inconvenience. It is a public health problem with measurable consequences that play out across multiple body systems in people who […]
