Reviewed by Lily Ramsey, LLM May 18 2023 Evidence that non-invasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer’s disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends to tactile stimulation. A new study by MIT scientists shows that Alzheimer’s model mice...

A self-administered mobile app to detect Alzheimer’s disease using speech data
by University of Tsukuba Credit: Sergey Nivens/Shutterstock Alzheimer’s disease (AD) is the most common form of dementia. It is important to start intervention from an early stage, e.g., the mild cognitive impairment (MCI) stage, to prevent or delay the progression of AD. For the early detection of AD and MCI, there is a growing need to...

Study provides evidence that breathing exercises may reduce Alzheimer’s risk
by Constance Sommer, USC Leonard Davis School of Gerontology Credit: Unsplash/CC0 Public Domain The exercise was simple: inhale for a count of five, then exhale for a count of five. Do that for 20 minutes, twice a day, for four weeks. These brief breathing sessions had significant impacts: Volunteers’ heart rate variability increased during each exercise period...

Deep sleep may mitigate Alzheimer’s memory loss, research shows
by Jason Pohl, University of California – Berkeley In people with similar amounts of beta-amyloid protein deposits, more deep sleep corresponded with improved memory function. Credit: Matthew Walker A deep slumber might help buffer against memory loss for older adults facing a heightened burden of Alzheimer’s disease, new research from the University of California, Berkeley, suggests. Deep sleep,...

Passing the sniff test: Can we train our brain to boost smell and memory?
by Deakin University Credit: CC0 Public Domain A new study is investigating whether learning to remember smells can boost memory more broadly and reduce the risk of dementia. The research, led by Dr. Alex Bahar-Fuchs from Deakin University’s School of Psychology, builds on a new body of evidence that shows training our memory for smells can improve brain...

Alzheimer’s: Could the brain’s glucose metabolism pave the way for new treatments?
How neurons consume and metabolize glucose could hold the key to new treatments for Parkinson’s and Alzheimer’s disease. Javier Zayas Photography/Getty Images Researchers investigated the glucose uptake and glucose metabolism in neurons. They found that neurons metabolize glucose themselves and that glucose metabolism is crucial for proper neuronal function. Further studies are needed to see whether...

MIT scientists discover ‘remarkable’ new way to reverse Alzheimer’s — as previous breakthrough drug found to slow disease under fire after causing death of trial participant
By CAITLIN TILLEY, HEALTH REPORTER FOR DAILYMAIL.COM UPDATED: 14:24 EDT, 14 April 2023 A new way to reverse Alzheimer’s has been discovered by scientists at the Massachusetts Institute of Technology (MIT) — a major breakthrough with ‘dramatic’ results. The researchers used a peptide, or string of amino acids, to interfere with an enzyme that is typically overactive in the brains of people with...

Alzheimer’s risk patients may beefit from Mediterranean keto diet, study shows gut microbiome changes
By Neha Mathur Apr 9 2023 Reviewed by Danielle Ellis, B.Sc. In a recent study published in the Journal of the Alzheimer’s Association (AA), researchers examined the effects of a low-carbohydrate-modified Mediterranean ketogenic diet (MMKD) on the gut microbiome and metabolome of patients at risk for Alzheimer’s disease (AD). Study: Effects of a ketogenic and low-fat diet on the...
