New research affirms the importance of maintaining a healthy gut microbiome

A compelling new study has described a novel association between viral infections, neurodegenerative disease, the gut microbiome, and our immune system. The research suggests gut bacteria disruptions can allow harmful viruses to trigger neurological diseases such as multiple sclerosis.

New insights into why women develop Alzheimer's more than men

Posted on by

Differences in the way toxic proteins spread through male and female brains could help explain why ...

Two new studies presented recently at the Alzheimer’s Association International Conference in Los Angeles are shedding light on the longstanding mystery of why women suffer from Alzheimer’s and dementia at higher rates than men. As well as discovering sex-specific genes associated with Alzheimer’s risk, the researchers describe how toxic dementia-causing proteins spread differently through female brains.

Two studies show a healthy lifestyle can significantly offset any genetic predisposition a person may have ...

Two new studies presented recently at the Alzheimer’s Association International Conference affirm the potential for a healthy lifestyle to reduce the risk of age-related dementia and cognitive decline. The research particularly suggests lifestyle factors can counteract genetic predispositions for Alzheimer’s disease.

Common hypertension drug boosts blood flow to the brains of Alzheimer’s patients

Posted on by

Previous research has link declines in blood flow to the brain with the early stages of ...

Through a string of interesting studies scientists have been able to probe the links between blood flow to the brain and declining cognitive function. One particularly promising and recent example demonstrated how a drug commonly used for high blood pressure could be used to treat diseases like Parkinson’s and dementia. Scientists in the Netherlands have now uncovered another candidate, finding an existing drug used for hypertension was able to boost blood flow to memory and learning regions in the brains of Alzheimer’s patients.

Memory-preserving particles could form part of an Alzheimer's vaccine puzzle

Posted on by

A new type of virus-like particle has been shown to improve Alzheimer’s symptoms in mice. Could ...

Alzheimer’s is a disease with a number of potential causes and therefore a number of potential targets for prevention. One of those centers on a protein call tau, which can gather in long tangles that kill off neurons in the brain. Scientists have developed what they describe as a vaccine to keep the brain clear of these dangerous clumps, and found that treating mice in this way helped stave off the kind of memory decline associated with the disease.

Higher education doesn’t prevent Alzheimer’s but it can offer a cognitive head start

Posted on by

In a new study, higher education does seem to give Alzheimer's patients a cognitive head start ...

Scientists have long debated why there seems to be an association between higher levels of education and lower rates of Alzheimer’s disease in later life. New research from Johns Hopkins Medicine is suggesting neurodegenerative disease is just as prevalent in more-educated individuals but a greater cognitive reserve can temporarily mitigate the impact of Alzheimer’s pathology in one’s senior years.

New research suggests a mechanism by which certain virus particles may be accelerating the accumulation of ...

An intriguing new study from researchers at Stockholm University and Karolinska Institutet has described a mechanism by which virus particles can interact with proteins in biological fluids and become more infectious, while also accelerating the formation of plaques often associated with neurodegenerative diseases such as Alzheimer’s.

A VR navigation task can accurately distinguish patients with age-related mild cognitive impairment from patients with ...

An exciting new study from the University of Cambridge is demonstrating how a novel virtual reality navigation test can better predict which patients are in the early stages of Alzheimer’s disease compared to other currently used “gold standard” cognitive tests.
