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.
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.
Hidden ancestral links found in motor neuron disease and dementia could speed up gene discovery

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).

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
Discovery of 'item memory' brain cells offers new Alzheimer's treatment target

Researchers have discovered the neurons responsible for 'item memory,' deepening our understanding of how the brain stores and retrieves the details of 'what' happened and offering a new target for treating Alzheimer's disease.
New dementia risk tool designed for the countries that need it most

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

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.
Large-scale genetic study on Alzheimer's identifies new DNA risks
Source: Medical Xpress – Dementia
A large-scale international study offers new insights for understanding Alzheimer's disease and developing future treatments. The University of Exeter–led PROTECT study was part of the research, led by Vrije Universiteit Amsterdam and published in Nature, which sheds clearer light on the role of immune cells within the brain, as well as several specific neuronal cell types.

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.
Nearly 75% of former NFL players who died between 2008 and 2023 had CTE, analysis estimates

A new study led by Boston University researchers estimates that nearly 75% of all NFL players who died between 2008 and 2023 had chronic traumatic encephalopathy (CTE) neuropathology. CTE is a neurodegenerative disease that has been diagnosed in individuals with substantial exposure to repetitive head impacts. It can only be definitively diagnosed after death.

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
