Sleep apnea may be a causal factor for Alzheimer’s, study concludes

Posted on November 9, 2022 by Rich Haridy

A new study has added to a large body of observational evidence linking sleep apnea to Alzheimer's by demonstrating in mice how disordered sleep breathing affects the brain

New research in Nature Communications has strengthened the link between sleep apnea and dementia, by using novel preclinical models to demonstrate exactly how breathing disruptions during sleep can cause brain changes associated with Alzheimer’s disease.

Don’t worry – Picking your nose doesn’t cause Alzheimer’s disease

Posted on November 3, 2022 by Rich Haridy

Could picking your nose really contribute to the onset of Alzheimer's disease?

It’s been a rough week for nose-pickers around the world, with a torrent of news headlines loudly declaring “scary evidence” has been found showing Alzheimer’s disease is linked with a bit of finger-based nasal exploration. Turns out this link comes from a deeply speculative press release and, according to several neuroscientists New Atlas contacted, is “extremely unlikely.”

Declining anti-inflammatory molecules may play key role in brain aging

Posted on November 1, 2022 by Rich Haridy

A new study is the first to provide evidence a type of fat cell, previously studied in rodent brains, can also be found in human brains

Researchers have discovered a unique type of fat molecule in the brain may have anti-inflammatory effects and play a crucial role in preventing age-related neurological disease. Animal studies demonstrate levels of the molecule decline with age and their absence could contribute to brain inflammation associated with age-related neurodegeneration.

Memory-enhancing “super neurons” discovered in the brains of SuperAgers

Posted on October 3, 2022 by Nick Lavars

A new study has discovered the existence of enlarged neurons in the brains of SuperAgers

Scientists studying the brains of so-called “SuperAgers” have discovered a set of significantly enlarged neurons associated with memory. These neurons also appeared more resistant to characteristics of Alzheimer’s disease, and present as a unique biological signature that these subjects may have carried throughout their whole lives.

New trial finds first-ever Alzheimer’s drug to slow cognitive decline

Posted on September 29, 2022 by Rich Haridy

Over 18 months those on lecanemab showed a 27% slower rate of cognitive decline compared to those in the placebo group

Pharmaceutical companies Eisai and Biogen have announced the first results from a Phase 3 human trial testing a drug designed to treat symptoms of dementia associated with Alzheimer’s disease. The drug seems to be successful at slowing cognitive decline, making it the first drug to ever effectively treat Alzheimer’s symptoms. However, experts are cautious in their optimism, suggesting more information is needed to understand exactly how meaningful this treatment will be for patients in the real world.

Older COVID-19 survivors face increased Alzheimer’s risk, study finds

Posted on September 15, 2022 by Rich Haridy

It is still unclear whether COVID-19 is hastening the progression of pre-existing neurodegeneration or prompting new disease

A new study tracking the health of more than six million older Americans over 2020 and 2021 has found COVID-19 nearly doubles a person’s risk of developing Alzheimer’s disease in the year following infection. The findings add to a growing body of research indicating SARS-CoV-2 infections can affect progression of several neurodegenerative diseases.

Oxford study finds increased dementia risk 2 years after COVID infection

Posted on August 18, 2022 by Rich Haridy

New research is some of the first to look at the long-term effects of a COVID infection up to two years after the acute illness

New research published in The Lancet Psychiatry has offered the most comprehensive look at the long-term neurological effects of COVID-19 published to date, tracking more than one million people for up to two years. The findings revealed an increased risk of mood disorders such as depression and anxiety, following SARS-CoV-2 infection, returns to normal after a few months but increased rates of dementia are still being detected in older adults up to 24 months after the acute disease.

Study of Alzheimer’s risk gene reveals potentially reversible mechanism

Posted on August 5, 2022 by Michael Irving

A new study has found that lipid metabolism may be a mechanism for Alzheimer's, and could be reversible

MIT scientists have uncovered a mechanism for how a common genetic risk factor for Alzheimer’s contributes to the disease. It centers on lipid metabolism, and early investigations suggest it could eventually lead to new treatments to slow disease progression.

Brain volume study reveals anti-aging potential of taking the stairs

Posted on August 5, 2022 by Nick Lavars

A new study suggests that even a moderate uptake of physical activity, such as taking the stairs instead of the elevator, can counter volume loss in key brain regions

Although we generally understand exercise to be good fo us in all sorts of ways, scientists continue to make interesting inroads around the specifics of this relationship. The latest comes from a team in Germany which has found that even slight changes to regular physical activity, such as taking the stairs instead of the elevator, can counter the age-related loss of volume in brain regions linked to disease.

One-two punch from pair of common viruses may trigger Alzheimer’s disease

Posted on August 1, 2022 by Rich Haridy

A new study speculates the chicken pox virus can reactivate a dormant herpes infection, leading to the development of Alzheimer's disease

A fascinating new collaborative study, between researchers at the University of Oxford and Tufts University, has found two common viruses may be working in tandem to trigger the earliest stages of Alzheimer’s disease. The findings build on a growing body of evidence implicating the herpes virus in neurodegenerative disease.
