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.
-
NewsStudy shows head trauma may activate latent viruses, leading to neurodegeneration
Researchers have uncovered mechanisms that may connect the dots between trauma and the emergence of disease, pointing to latent viruses lurking in most of our brains that may be activated by the jolt, leading to inflammation and accumulating damage.
-
NewsHerpes virus might drive Alzheimer’s pathology, study suggests
Researchers have uncovered a surprising link between Alzheimer’s disease and herpes simplex virus-1 (HSV-1), suggesting that viral infections may play a role in the disease.
-
NewsThe surprising role of gut infection in Alzheimer’s disease
A new study implicates link between a common virus and the disease, which travels from the gut to the brain and may be a target for antiviral treatments.
-
NewsHealing the gut can reduce long-term impact of stroke, new research finds
A new study found that a drug that was effective at protecting the brain in the immediate aftermath of a stroke failed to prevent long-term cognitive impairment when applied only to the brain. The same drug, when applied to the gut, reduced impairment significantly.

NewsSilent intruder: How the cold sore virus maps its way through the brain
Researchers provide a better understanding of the long-term consequences of HSV-1 infection.
