Living in a Noisy Neighborhood May Cause Alzheimer’s Disease, According to Recent Study

Alzheimer; News from the web:

Individuals who reside in louder regions are more at risk of developing Alzheimer’s, new report shows.

A sound-level spike of only 10 decibels raised the risk by 30 percent. That is the gap between breathing and whispering. It also culminated in 36 percent greater chances of moderate cognitive disability, including memory and reasoning ability, scientists said.

Improving apathy in Alzheimer patients with brain stimulation

Alzheimer; News from the web:

Twenty Veterans with Alzheimer’s disease and apathy took part in a pilot study. Half received repetitive transcranial magnetic stimulation (rTMS), a type of brain stimulation. The others received sham stimulation, basically a placebo.

Through patient and caregiver interviews, the VA team documented “significantly greater improvement” in apathy levels in those who received brain stimulation compared with the control group. The positive effects continued up to three months.

Besides improvements in apathy, the researchers also noted “significantly greater improvement” in memory, attention, and cognition in the rTMS patients compared with the sham treatment group.

Helping Alzheimer’s Patients Bring Back Memories

Alzheimer; News from the web:

The writer of the post in our link for today  developed an approach that allowed us to activate the neurons that store memory information, referred to as memory engrams, through optogenetics—that is, introducing a gene that is light sensitive into the memory engram cells of “Alzheimer’s” mice, then delivering blue light pulses to activate them—and measuring memory recall strength directly. To our surprise, we found comparable numbers of engram cells in normal healthy animals and Alzheimer’s animals, suggesting that the initial memory storage process is intact. Targeting the recall process in Alzheimer’s animals led to an improvement in their memory, which reached the performance level of normal animals.

A Vaccine for Alzheimer’s Disease?

Alzheimer; News from the web:

Swiss biopharma AC Immune has made targeting Alzheimer’s disease, the leading form of dementia, a top priority. The company’s numerous candidates and platforms target several different proteins and pathways thought to have a central role in Alzheimer’s pathology. 2020 has brought mixed news for AC Immune. In July, the company announced that their candidate tau vaccine, ACI-35.030, had shown “encouraging” safety data at a lower dose and was to be progressed to a higher-dose group. However, September brought the disappointing news that their anti-tau antibody, semorinemab, did not meet its primary efficacy endpoints in a Phase 2 trial. To discuss AC Immune’s work, Technology Networks spoke to CEO Prof. Andrea Pfeifer.

FDA does not approve new Alzheimer’s drug

Alzheimer; News from the web:

Government health advisers sharply criticized a closely watched Alzheimer’s drug on Friday, concluding there wasn’t enough evidence that the experimental drug slowed the brain-destroying disease.

The panel of outside experts for the Food and Drug Administration agreed that a pivotal study in patients failed to show “strong evidence” that the drug worked. The experts warned of multiple “red flags” with the data, which did not initially show any benefit until another analysis with later results.

First Alzheimer’s Blood Test Rolled Out for Clinical Use in US

Alzheimer; News from the web:

The first blood test designed to assist physicians in determining whether a patient has Alzheimer’s disease is now available in most US states, the company C2N Diagnostics announced October 29. The test measures biomarkers that frequently reflect the presence of amyloid plaques in the brain—a hallmark of Alzheimer’s—as well as the presence of a gene variant that increases the risk of the disease.

See Alzheimer’s coming eight years ahead

Alzheimer; News from the web:

An artificial intelligence (AI) tool was able to accurately predict Alzheimer’s disease almost eight years before a person was diagnosed, according to a study recently published in the journal EClinicalMedicine, and researchers say the tool could help providers to identify patients in early stages of the disease.

sleep apnea and Alzheimer’s

Alzheimer; News from the web:

New research seems to suggest that both cause the same brain damage.

A new study confirms links between obstructive sleep apnea and Alzheimer’s disease. Possible reasons for the association include the build up of toxic products due to lack of oxygen.

Alzheimer’s and Immunotherapy

Alzheimer; News from the web:

Immunotherapy is the prevention or treatment of disease with drugs that stimulate an immune response. Scientists are looking for a cure to Alzheimer’s disease that boosts our immune systems. Administering drugs to elicit an immune response works in a similar way to a vaccine and pharmaceutical companies are placing bets on immunotherapy to target Alzheimer’s disease.

vascular risk factors and subsequent Alzheimer’s disease

Alzheimer; News from the web:

The clinical guidelines related to the primary prevention of Alzheimer’s disease (AD) have focused on the management of vascular risk factors. However, the link between vascular risk factors and AD in older adults remains unclear. This study aimed to determine the association between vascular risk factors and subsequent AD in 178,586 older adults (age ≥ 65 years).

The gender gap with Alzheimer’s

Alzheimer; News from the web:

Why are women diagnosed more with Alzheimer’s than men?

One study found menopause, which reduces estrogen levels in a women’s body, may be to blame. Scientists scanned the brains of women and men and found declines in estrogen were involved in Alzheimer’s abnormalities.

Another recent report found women with more belly fat had a higher risk for dementia than men with the same issue. Specifically, women with a higher waist circumference had a 39% increased risk of dementia in 15 years.

And researchers recently performed brain scans on more than 1,000 older adults and found women metabolized sugar better, which may help them compensate for dementia damage better causing a delayed diagnosis.

research finds antidepressants may reduce signs of Alzheimer’s

Alzheimer; News from the web:

A new study from a Penn researcher adds to evidence that a class of antidepressant drugs known as SSRIs may reduce production of a key protein found in the brains of people with Alzheimer’s disease. This is evidence, she said, that the drugs could someday be part of a cocktail used to prevent or delay this form of dementia.

Artificial Intelligence and Alzheimer’s

Alzheimer; News from the web:

A team led by Dr Laura Ferraiuolo of The University of Sheffield have found that AI could be used to assess and monitor potential patients. Specifically, machines could be programmed to recognise Alzheimer’s by looking at an image of a patient’s brain, as well as assessing their movements and speech to determine if they are likely to be suffering from the condition before symptoms progress.

Navigation trouble could be a signal

Alzheimer; News from the web:

Researchers compared the navigation performance of 202 volunteers without genetic Alzheimer’s risk and 65 volunteers with increased genetic risk. The latter had a specific expression of the gene for apolipoprotein E, the APOE-ε4 allele.

A better test for Alzheimer’s

Alzheimer; News from the web:

Clinical trials of Alzheimer’s medicines have failed frequently but now researchers believe that this may have been caused by the drugs given too late. So if they could just develop a test that would detect Alzheimer’s earlier, it would make the drugs that have failed for use later in the process, so much more productive.
