Alzheimer’s Disease: Protective Immune Cells Active Decades Before Symptom Onset
Boosting the brain’s defenses could help combat the disease. In individuals with a genetic predisposition to Alzheimer’s disease, the immune cells of the brain –…

“Vicious Cycle” Discovered Between Excessive Daytime Napping and Alzheimer’s Dementia
In a study of older adults, longer, more frequent daytime napping in a specific year predicted worse cognitive performance in the following year, and vice…
Bacteria in the Nose Can Sneak Into the Brain – May Increase Risk of Alzheimer’s Disease
New research from Griffith University has shown that a bacterium commonly present in the nose can sneak into the brain and set off a cascade…
Skin Cancer Cells Sabotage Brain’s Immune Defenses With Alzheimer’s Protein
Amyloid beta, a protein known to build-up in the brains of Alzheimer’s patients, also helps skin cancer cells thrive when they spread to the brain,…
Damage to General Intelligence Brain Networks Causes Dementia Patients To Struggle With Change
People with dementia struggle to adapt to changes in their environment because of damage to areas of the brain known as ‘multiple demand networks’, highly-evolved…
A Protein That Is Too Effective: The Role of Lipids in the Development of Alzheimer’s Disease
A European consortium coordinated by UNIGE shows how a mutation in the APOE protein changes the lipid transport in the brain and could promote the…
New Evidence Uncovered: Women Are More Susceptible to Alzheimer’s Disease
Epidemiological studies have shown that women are twice as likely as men to develop Alzheimer’s disease (AD), but the cause of this phenomenon has been…
Improved Physical Fitness Linked to Lower Risk of Alzheimer’s Disease
People who are more physically fit are less likely to develop Alzheimer’s disease than people who are less physically fit, according to a preliminary study…
Depression and Alzheimer’s Disease Share Common Genetic Roots
Epidemiological data have long linked depression with Alzheimer’s disease (AD), a neurodegenerative disease characterized by progressive dementia that affects nearly 6 million Americans. Now, a…
Brain’s Ability To Clear Protein Linked to Alzheimer’s Disease Controlled by Circadian Cycle
Ability of immune system to destroy Alzheimer’s-related protein oscillates with daily circadian rhythm. The brain’s ability to clear a protein closely linked to Alzheimer’s disease…
A Simple Eye Test May Identify Risk of Alzheimer’s in Middle Age
A simple eye test may make diagnosing the earliest stages of ‘diseases of old age’ possible when people are much younger, University of Otago researchers…
Circadian Rhythms Control Immune Cells That Clear Away Alzheimer’s Disease Protein
The findings provide a mechanism that links Alzheimer’s disease with circadian rhythm disruptions. Researchers report that the immune cells responsible for clearing away a key…
Brain Damage Higher Over Short Term in COVID-19 Patients Than in Alzheimer’s Patients
Patients hospitalized for COVID-19 had higher levels over the short term of blood proteins known to rise with neurological damage than non-COVID-19 patients diagnosed with…
Cognitive Decline Is Not Always a Sign of Alzheimer’s Disease
Some cognitively frail adults have impaired cognition but intact brain structure and function. At the first sign of cognitive trouble, people often worry Alzheimer’s disease…
Exercise Alters Brain Chemistry To Protect Aging Synapses From Alzheimer’s and Dementia
Enhanced nerve transmission seen in older adults who remained active. When elderly people stay active, their brains have more of a class of proteins that…
Stopping Dementia at the Nose – Nasal Spray To Treat, Prevent Alzheimer’s Disease
Via drug repositioning, Osaka City University creates combination of rifampicin and resveratrol and have shown in mouse models that the nasal administration improves cognitive function…
A Common Risk Factor for Alzheimer’s Disease May Predispose Carriers to Severe COVID-19, Cerebral Microhemorrhages
A study conducted at the University of Helsinki and the Helsinki University Hospital suggests that the APOE4 allele may also increase cerebral microhemorrhages related to…
How Toxic Aggregates Form and Kill Brain Cells in Prion Diseases
Scripps Research Discovery Illuminates How Brain Cells Die in Prion Diseases Researchers show how toxic aggregates are formed inside brain cells, and how to block…
