NewsNew research offers avenue to explore relationship between Alzheimer’s and HIV
Researchers have created an animal model that helps resolve questions about the relationship between HIV and Alzheimer’s disease (AD). The virus that drives the root cause of AD initiates a complex chain that, with other disease partners, drives nerve cell injury and cognitive impairments for AD pathology.

NewsCommon virus rewires energy metabolism in human neurons
Advanced optical imaging techniques reveal viral infection reshapes neuron metabolism long before major cell damage appears.

NewsTuberculosis vaccine changes brain’s immune environment and Alzheimer’s biomarkers in older adults
A study shows that BCG vaccines can alter immune responses and amyloid-beta biomarkers in non-Alzheimer’s participants, which may help explain previously observed links to lower disease risk.

NewsStudy uncovers gut microbial patterns linked to Alzheimer’s disease in Puerto Rico - even showing up long before diagnosis
A new investigation into the links between Alzheimer’s disease and the gut microbiome in Puerto Rico has found specific gut microbial patterns associated with cognitive decline, disease severity and genetic risk factors.

NewsReview highlights antimicrobial peptides as cross-seeding modulators at the neurodegenerative–infectious interface
In a comprehensive review, researchers synthesize emerging evidence that antimicrobial peptides and disease-related amyloids can influence one another through heterotypic cross-seeding interactions.

NewsRisk of Alzheimer’s dementia significantly reduced after high-dose influenza vaccination compared to the standard dose
The risk of Alzheimer’s disease significantly decreases in older adults who receive a higher dose of the influenza vaccine compared to the standard dose, according to new research.

NewsUrinary tract infections can trigger delirium and worsen dementia
Urinary tract infections can pose serious risks for older adults, particularly those with Alzheimer’s disease and other forms of dementia. In older patients, a common UTI can trigger delirium, a medical emergency marked by sudden confusion and altered awareness.

NewsLong COVID linked to Alzheimer’s disease mechanisms
The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer’s disease and greater levels of dementia, a new study finds.

NewsCommon bacteria discovered in the eye linked to cognitive decline
Chlamydia pneumoniae can linger in the eye and brain for years and may aggravate Alzheimer’s disease. Research suggests this bacterium can amplify Alzheimer’s disease and points to potential interventions including inflammation-limiting therapies and early antibiotic treatment.

NewsNew research suggests gut bacteria may be linked to memory decline in mild cognitive impairment and Alzheimer’s disease
A new review is shedding light on the growing evidence that gut microbiome imbalances—known as dysbiosis—may play a key role in the development and progression of mild cognitive impairment (MCI) and Alzheimer’s disease.

NewsIn a nasal spray, gold nanoparticles deliver a targeted treatment to the brain
In the form of a ‘nasal spray’, tiny gold particles act as carriers, delivering a treatment directly to the brain: a new nanotechnological device for the treatment and prevention of neuropsychiatric and neurodegenerative diseases and infections.

NewsDo stranded dolphins have Alzheimer’s disease - and how are cyanobacteria involved?
Scientists have come up with an unusual hypothesis: perhaps dolphins become disoriented by suffering from a form of Alzheimer’s disease. It appears that Alzheimer’s-type neuropathology and disorientation may result from chronic exposure to toxic molecules produced by cyanobacteria.

NewsAnti-neuroinflammatory natural products from isopod-related fungus now accessible via chemical synthesis
Herpotrichone is valued for its ability to suppress inflammation in the brain and protect nerve cells, but could only be obtained in minute quantities from fungi that are symbiotic with isopods. Researchers have succeeded in chemically synthesizing this rare natural product.

NewsHow bacteria use a protein associated with Alzheimer’s to fight off threats
Amyloids are perhaps best known as a key driver of Alzheimer’s disease. According to new research, these oft-maligned proteins also serve a critical role for bacteria in our environment, enabling them to fight off other “predatory bacteria.”

NewsAntiviral treatment fails to slow early-stage Alzheimer’s
A clinical trial has found that a common antiviral for herpes simplex infections, valacyclovir, does not change the course of the disease for patients in the early stages of Alzheimer’s.
-
NewsCold sore viral infection implicated in development of Alzheimer’s disease
Symptomatic infection with the virus responsible for cold sores around the mouth–herpes simplex 1, or HSV-1 for short—may have a key role in the development of Alzheimer’s disease, suggests a large pharma industry-funded US study.
-
NewsNew treatment targets link between viral infection and Alzheimer’s disease
A unique mechanism triggering Alzheimer’s disease draws attention: viral infection—while ALT001 is confirmed to alleviate neuroinflammation and suppress viral replication.
-
NewsHerpesviruses may contribute to Alzheimer’s disease via transposable elements
Researchers have outlined the pathway human herpes simplex virus-1 (HSV1) can use to contribute to Alzheimer’s disease in aging brains, and also share two FDA-approved, commercially available drugs that reverse this pathway in a laboratory setting.

NewsMouth bacteria may hold insight into your future brain function
A study revealed that the types of bacteria in our mouths may have direct impacts to brain health, which would link mental illness, such as Alzheimer’s disease or dementia.

NewsOral microbiome may affect cognitive function as we age
The microbial ecosystems within our mouths may affect our cognitive function as we age, according to a study. Interventions such as prebiotics, including dietary nitrate, have potential for delaying cognitive decline.
