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 […]
How diabetes affects brain aging and what you can do about it
Diabetes, particularly type 2 diabetes and prediabetes, has been linked to accelerated brain aging and an increased risk of cognitive decline. Recent research from the Karolinska Institutet highlights the importance of healthy lifestyle choices in mitigating these risks. The link between diabetes and brain health Prediabetes and type 2 diabetes are associated with brain-related health […]
Innovative dementia screening: The promise of the McSCI test
As the global population ages, the urgency for early and accurate dementia diagnosis increases. Researchers from Murdoch University have developed a promising tool, the McCusker Subjective Cognitive Impairment Inventory (McSCI), designed to enhance early detection of dementia through a self-reported questionnaire covering six cognitive areas, including memory, language, and attention. Understanding the importance of early […]
