A healthy lifestyle may counteract diabetes-associated brain ageing

2024-08-28
(Press-News.org) Type 2 diabetes and prediabetes are associated with accelerated brain ageing, according to a new study from Karolinska Institutet in Sweden published in the journal Diabetes Care. The good news is that this may be counteracted by a healthy lifestyle.

Type 2 diabetes is a known risk factor for dementia, but it is unclear how diabetes and its early stages, known as prediabetes, affect brain ageing in people without dementia. Now, a comprehensive brain imaging study shows that both diabetes and prediabetes can be linked to accelerated brain ageing.

The study included more than 31,000 people between 40 and 70 years of age from the UK Biobank who had undergone a brain MRI scan (magnetic resonance imaging). The researchers used a machine learning approach to estimate brain age in relation to the person’s chronological age.

Prediabetes and diabetes were associated with brains that were 0.5 and 2.3 years older than chronological age, respectively. In people with poorly controlled diabetes, the brain appeared more than four years older than chronological age. The researchers also noted that the gap between brain age and chronological age increased slightly over time in people with diabetes. These associations were attenuated among people with high physical activity who abstained from smoking and heavy alcohol consumption.

“Having an older-appearing brain for one’s chronological age can indicate deviation from the normal ageing process and may constitute an early warning sign for dementia,” says the study’s lead author Abigail Dove, a PhD student at the Department of Neurobiology, Care Sciences and Society, Karolinska Institutet. “On the positive side, it seems that people with diabetes may be able to influence their brain health through healthy living.”

Repeated MRI data were available for a small proportion of the study participants. Follow-up MRI scans are ongoing and researchers are now continuing to study the association between diabetes and brain ageing over time.

“There’s a high and growing prevalence of type 2 diabetes in the population,” says Abigail Dove. “We hope that our research will help prevent cognitive impairment and dementia in people with diabetes and prediabetes.”

The study was mainly funded by the Swedish Alzheimer’s Foundation, the Dementia Research Fund, the Swedish Research Council and Forte (the Swedish Research Council for Health, Working Life and Welfare). There are no reported conflicts of interest.

Epigenetics blood markers can help understand dementia risk

2024-08-28
New research suggests that epigenetic markers in the blood could be useful for  understanding dementia risk. Two linked papers from the University of Exeter and Maastricht University have together progressed research to show the potential for DNA methylation, an epigenetic marker, in understanding how genetics and lifestyle factors influence dementia risk. DNA methylation is a chemical tag added to DNA, which can turn genes on and off. Genetic and lifestyle factors can alter the levels of the DNA methylation tag on genes, with some of these factors already known to increase the risk of developing dementia. By assessing DNA methylation this can help scientists ...

In-person contact linked with lower levels of loneliness in older adults

In-person contact linked with lower levels of loneliness in older adults
2024-08-28
EMBARGO UNTIL 6 A.M. EST, WEDNESDAY AUG. 28, 2024.   In-person contact helps lead to lower levels of loneliness in older people, but other ways of staying in touch, such as phoning, emailing or texting, are not as effective in lowering loneliness, a team of researchers at The University of Texas at Austin and the University of Michigan have found. The findings, out today in the The Journals of Gerontology: Series B Psychological Science, have implications for the health and well-being of many older people. “We were interested to see how older adults react ...

Alternatives in car and aircraft construction: New joining and additive manufacturing processes allow adhesive-free joining of wood and metal

Alternatives in car and aircraft construction: New joining and additive manufacturing processes allow adhesive-free joining of wood and metal
2024-08-28
The renewable raw material wood is climate-neutral and at the same time light and strong, making it fundamentally attractive for use in vehicle manufacturing. One challenge to date has been joining the wood and the other materials in the vehicle, such as metals and polymer composites, in a robust way. The research team led by Sergio Amancio from the Institute of Materials Science, Joining and Forming of Graz University of Technology (TU Graz) - Gean Marcatto, Awais Awan, Willian Carvalho and Stefan Herbst - has now successfully tested two techniques by which extremely strong joints can be achieved without using adhesives or screws. ...

Researchers develop novel organic redox-active molecules for flow batteries
2024-08-28
Organic redox-active molecules (ORAMs) are abundant and diverse, offering significant potential for cost-effective and sustainable energy storage, particularly in aqueous organic flow batteries (AOFBs). However, ensuring the stability of the ORAMs during the charge and discharge process is critical, as side reactions can deactivate them and eliminate their redox activity. Air stability remains a challenge for many ORAMs, complicating their practical use. Recently, a research group led by Prof. LI Xianfeng and Prof. ZHANG Changkun from ...

What role did fear play in Europe's population growth?

What role did fear play in Europes population growth?
2024-08-28
[Vienna, August 26 2024] – Since the end of the last Ice Age, growth of human population was far from uniform, marked instead by periods of rapid expansion followed by sharp declines. The reasons behind these fluctuations remain only partially understood. Previous research by CSH scientists Peter Turchin, Daniel Kondor, and an international team of collaborators, demonstrated that social conflicts, rather than – or in addition to – environmental factors, could have significantly impacted these patterns. Now, they add another piece to the puzzle. Wars and conflicts not only cause direct casualties but also create an atmosphere of distress ...
