How exercise may protect against Alzheimer’s

Athletes know a vigorous workout can release a flood of endorphins: “feel-good” hormones that boost mood. Now there’s evidence that exercise produces another hormone that may improve memory and protect against Alzheimer’s disease, according to a study co-led by Ottavio Arancio, MD, PhD, a researcher at Columbia University’s Vagelos College of Physicians and Surgeons and […]

Scientists pave the way for saliva test for Alzheimer’s disease

University of Alberta scientists have identified three biomarkers for detecting mild cognitive impairment and Alzheimer’s disease in saliva samples. The research has promising results for application in a clinical setting. The research team combines expertise in metabolomics from Liang Li, professor in the Department of Chemistry, and neurodegenerative disorders from Roger Dixon, professor in the […]

What helps people live well with dementia

New research has identified the factors that enable people with dementia and their carers to live as well as possible. Led by the University of Exeter, the research seeks to inform support services and guide policy on where resources should be spent to support the 50 million people worldwide that have been diagnosed with a […]

More daytime sleepiness, more Alzheimer’s risk?

Analysis of data captured during a long-term study of aging adults shows that those who report being very sleepy during the day were nearly three times more likely than those who didn’t to have brain deposits of beta amyloid, a protein that’s a hallmark for Alzheimer’s disease, years later. The finding, reported Sept. 5 in […]

How exercise generates new neurons, improves cognition in Alzheimer’s mouse

A study by a Massachusetts General Hospital (MGH) research team finds that neurogenesis -inducing the production of new neurons — in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer’s disease. Their investigation shows that those beneficial effects on cognition can be blocked by the hostile […]

Paro the robotic seal provides unconditional love for aged care residents

Meet Paro the seal. Made in Japan, he is a robot, and responds to touch with movements and sound. He is also a pet and a best friend for aged care residents in the rural Queensland town of Gayndah. “It looks like a baby harp seal … he does nuzzle and close his eyes, anything […]

Understanding the origin of Alzheimer’s, looking for a cure

After a decade of work, a team led by Hôpital Maisonneuve-Rosemont researcher and Université de Montréal associate professor Dr. Gilbert Bernier has shed promising light on the origin of the most common and prevalent form of Alzheimer’s disease, hoping to someday help mitigate or even reverse the progress of the disease. The team’s results are […]

Dementia patients could remain at home longer thanks to ground breaking technology

Innovative new technology will enable people with dementia to receive round the clock observation and live independently in their own homes, a new study in the Journal PL0S One reports. During this unique study, researchers from the University of Surrey in partnership with Surrey and Borders Partnership NHS Foundation Trust have developed state of the art AI […]

How does alcohol influence the development of Alzheimer’s disease?

Research from the University of Illinois at Chicago has found that some of the genes affected by alcohol and inflammation are also implicated in processes that clear amyloid beta — the protein that forms globs of plaques in the brain and which contributes to neuronal damage and the cognitive impairment associated with Alzheimer’s disease. Previous […]

4 New AI software accurately identifies commonest cause of stroke and dementia

Machine learning has detected one of the commonest causes of dementia and stroke, in the most widely used form of brain scan (CT), more accurately than current methods. New software, created by scientists at Imperial College London and the University of Edinburgh, has been able to identify and measure the severity of small vessel disease, […]
