Drinking 2–3 cups of coffee a day linked to dramatically lower dementia risk
Source: ScienceDaily – Alzheimer's
Drinking two to three cups of caffeinated coffee daily was linked to a dramatically lower risk of dementia and better cognitive functioning in a study spanning up to 43 years. The benefits appeared regardless of genetic risk, but decaffeinated coffee did not show the same association.
Scientists reverse Alzheimer’s in mice with breakthrough nanotechnology Preliminary / early-stage research
Source: ScienceDaily – Alzheimer's (health)
A new nanotechnology treatment reversed Alzheimer’s symptoms in mice by restoring the brain’s natural cleanup system. The specially engineered nanoparticles helped clear toxic amyloid proteins from the brain and repair the blood-brain barrier, which normally protects and regulates the brain’s environment. In one striking experiment, elderly mice treated with the therapy later behaved like healthy
Scientists find hidden driver of aging and a simple amino acid that fights memory loss in mice Preliminary / early-stage research
Source: ScienceDaily – Memory
Scientists discovered that declining levels of a protein called Menin may help drive aging, and restoring it in older mice reversed several age-related changes in just 30 days. Even more surprisingly, supplementing with a simple amino acid called D-serine improved memory and learning, offering a potential new approach to age-related cognitive decline.
Study finds more Alzheimer's-related brain changes in women with Parkinson's

Scientists discover new Alzheimer’s drug that repairs DNA damage and reduces brain inflammation
Source: ScienceDaily – Alzheimer's
Scientists have discovered that a drug originally developed for spinal cord injuries can tackle several key features of Alzheimer’s disease, including DNA damage and inflammation. Already tested for initial safety in humans, the experimental treatment could offer a faster path toward therapies that target the disease at its roots.
Discovery of 'item memory' brain cells offers new Alzheimer's treatment target

Scientists discover mysterious “lonely” brain waves linked to memory loss
Source: ScienceDaily – Alzheimer's
Scientists have uncovered a surprising link between Alzheimer’s-related protein buildup, disrupted brain waves during deep sleep, and fading memory. The findings suggest that hidden changes in how the brain processes memories overnight may contribute to age-related memory loss long before Alzheimer’s symptoms appear.
Rapid tau spread may explain why midlife Alzheimer's progresses more rapidly
Source: Medical Xpress – Dementia
Patients with early-onset Alzheimer's disease, whose symptoms start before age 65, have more extensive deposits of tau, a hallmark protein of the condition, compared with patients whose symptoms start at 65-plus, a new study found. What's more, tau accumulates at more than twice the rate in younger compared to older patients and spreads widely throughout the brain.

Scientists reverse liver cell aging and cut Alzheimer’s-linked protein in half Preliminary / early-stage research
Source: ScienceDaily – Alzheimer's
A surprising discovery suggests that rejuvenating the liver could help protect against Alzheimer’s disease and heart disease. USC researchers found that an experimental drug restored aging liver cells in rats, cutting levels of an Alzheimer’s-linked protein in half and bringing bad cholesterol down to youthful levels. The treatment also revived a previously unknown communication system that helps
Extreme heat days may increase dementia risk, with poorer communities facing greater vulnerability

Over 57 million people worldwide are living with dementia, with nearly 10 million new cases diagnosed each year, and scientists now say that people living in certain climatic conditions are at a greater risk than others of developing this neurodegenerative condition.

A simple blood test could reveal Alzheimer’s risk 10 years before symptoms
Source: ScienceDaily – Alzheimer's
A major international study found that a simple blood test could help predict Alzheimer’s-related cognitive decline years before symptoms appear, with the highest-risk individuals facing a 38% chance of impairment within five years and an estimated 78% chance within 10 years. Scientists believe the discovery could pave the way for earlier intervention and future treatments designed to prevent Alzh
Hidden ancestral links found in motor neuron disease and dementia could speed up gene discovery
Source: Medical Xpress – Dementia
Researchers at the Macquarie University Brain Institute and Clinic have helped accelerate the search for disease-causing genes by building new genetic 'families.' The team uncovered hundreds of previously unrecognized family connections by analyzing the DNA of people with frontotemporal dementia (FTD) and motor neuron disease (MND).

Low-dose aspirin linked to 70% lower dementia risk, but there's a catch
Source: ScienceDaily – Alzheimer's
A common, inexpensive medication could hold an unexpected clue to preventing dementia. Researchers found that older adults with a specific genetic profile had a 70% lower relative risk of dementia when taking low-dose aspirin, even though previous studies found no overall protective effect. The discovery suggests that genetics could help explain why some people benefit while others do not.

An international team led by Northumbria University has developed and validated a simple five-factor risk score to identify older people at elevated risk of dementia in low- and middle-income countries (LMICs)—where around 60% of the world's dementia cases now occur.

Scientists find a way to fight Alzheimer’s brain damage without removing toxic tau Preliminary / early-stage research
Source: ScienceDaily – Alzheimer's
Scientists have found a promising way to protect the brain from Alzheimer’s-related damage by blocking immune cells that contribute to the destruction of neurons. In mice, the treatment preserved roughly 40% more tissue in memory centers and improved memory, even without removing harmful tau protein buildup.

Walking just 3,000 steps a day could help slow Alzheimer’s-related brain changes, according to new research. Scientists discovered that physical activity was linked to less buildup of harmful tau proteins and nearly half the cognitive and functional decline, even in people already showing early signs of the disease. The strongest benefits appeared at 5,000 to 7,500 daily steps, suggesting that the
