First human trials test light & sound therapy for Alzheimer’s disease

Posted on December 14, 2022 by Rich Haridy

A promising new therapy for Alzheimer's involves exposure to a 40-Hz flickering light and sound tone for an hour a day

A new study published in the journal PLoS ONE has reported on the first human tests of an experimental therapy using sound and light to treat Alzheimer’s disease (AD). The initial findings are promising, with the unique treatment leading to some neurological and cognitive improvements, but the small trial size means more study is needed before anyone can say this type of therapy works.

Risk of Alzheimer’s linked with genetic propensity for ADHD

Posted on December 9, 2022 by Rich Haridy

A new study has found people with a high genetic risk score for ADHD display faster rates of cognitive decline compared to a matched group without the same genetic propensity

A genetic predisposition to attention-deficit/hyperactivity disorder (ADHD) has been linked to an increased risk of cognitive decline and Alzheimer’s disease in old age, according to new research from the University of Pittsburgh. The findings are the first to associate ADHD genetic risk with age-related cognitive impairment.

Hearing aids slow cognitive decline, but reasons why still a mystery

Posted on December 8, 2022 by Rich Haridy

A new meta-study has found using a hearing aid can be linked to lower risk of cognitive decline but it's still unclear exactly how the devices are preventing dementia

A first-of-its-kind meta-analysis comprising more than 100,000 participants has found a significant association between the use of hearing aids and a reduced risk of dementia. The findings raise the curious suggestion that using hearing restoration devices could somehow slow the progression of cognitive decline.

Yale study uncovers new potential root cause of Alzheimer’s disease

Scientists at Yale University have uncovered an overlooked mechanism that may be behind the symptoms of Alzheimer’s disease. The team points the finger at small swellings on axons near plaques that build up in the brain, and identified a protein that could be a biomarker for early detection of the disease as well as a target for future treatments.

Simple urine test proposed as early diagnostic tool for Alzheimer’s

Posted on November 30, 2022 by Rich Haridy

New research raises the possibility of a test that could detect Alzheimer's in its early stages

Alzheimer’s is a slow-moving neurodegenerative disease. Decades can pass before clinical symptoms appear, and even when they do it’s challenging to identify the disease in patients with mild cognitive impairment.

The amyloid rollercoaster continues as another big Alzheimer’s trial fails

Posted on November 17, 2022 by Rich Haridy

Are researchers wrong to keep working on anti-amyloid treatments for Alzheimer's after years of clinical trial failures?

A new announcement from pharmaceutical company Roche has revealed the failure of a massive global Phase 3 trial testing its latest anti-amyloid Alzheimer’s disease treatment. The failure marks another twist in the ongoing rollercoaster of research looking for drugs to reduce build-up of the protein commonly believed to be the primary pathological cause of Alzheimer’s neurodegeneration.

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.
