| High-Fiber Diet Eases Alzheimer’s Symptoms by Calming Gut-Brain Axis, Study Finds |
|
|
2025-09-16 21:15:06 +00:00
Feeding the animals a high fiber diet reduced Alzheimer ’s-related frailty, including tremors. The gut houses the body’s largest population of immune cells. A new study from the Buck Institute has revealed that in a mouse model of Alzheimer’s disease (AD), some of these immune cells can migrate along the brain-gut axis, pointing to a […]

| This Special Diet May Slow Brain Aging, Harvard Study Reveals |
|
|
2025-09-16 20:40:40 +00:00
The green-Mediterranean diet may protect against brain aging by reducing protein markers linked to cognitive decline. Adopting a green-Mediterranean diet, which incorporates green tea and the aquatic plant Mankai, has been linked to slower brain aging, according to recent research. The study, published in the journal Clinical Nutrition, was conducted by scientists from Ben-Gurion University, […]

| New Species of “Living Fossil” Fish Found Hiding in Plain Sight After 150 Years |
|
|
2025-09-16 08:44:57 +00:00
Researchers found dozens of Triassic coelacanth fossils in UK museums. The fish were once mistaken for reptile bones. The coelacanth is often called a “living fossil.” Once believed to have vanished millions of years ago, it was unexpectedly rediscovered in 1938 when one was caught in the Indian Ocean. Since then, several more specimens have […]

| New Biomarker Could Detect Alzheimer’s Years Before Symptoms Appear |
|
|
2025-09-16 03:06:23 +00:00
TSPO levels rise early in Alzheimer’s and persist throughout disease. Targeting this biomarker could open new treatment options. TSPO, a major marker of brain inflammation, may offer a way to detect Alzheimer’s disease long before memory problems and other symptoms develop. Findings published in Acta Neuropathologica suggest it could transform both diagnosis and treatment strategies. […]

| Lost Sleep May Leave Dangerous Toxins Lurking in the Brain |
|
|
2025-09-16 02:41:31 +00:00
Sleep may enhance the brain’s ability to remove harmful waste. Poor or disrupted sleep could raise dementia risk. The brain possesses its own system for removing waste, known as the glymphatic system, which is believed to become more active during sleep. When sleep is disrupted, this cleaning process may be impaired, slowing the removal of […]
