Lifestyle choices influence brain aging

While our birthdays mark the transition from one year to the next, it seems that certain parts of our bodies age at different rates. A new study draws our attention to the lifestyle choices that influence the rate of aging of our brains.

An international team searching for the secret of brain youth

An international team, led by researchers from the Karolinska Institute and the University of Gothenburg in Sweden, analyzed various biological signals to estimate brain age in septuagenarians without cognitive impairment. Their analysis, involving 739 people, highlighted the importance of vascular health in maintaining a young brain. Habits such as regular physical activity, healthy eating, stopping smoking and managing glucose levels can improve vascular health.

“Aged” brains linked to specific risk factors

“Aged” brains were associated with physical inactivity, diabetes, a history of stroke, as well as high levels of inflammation and blood glucose. These factors therefore have an interconnected impact on brain age. Thus, as neurobiologist Anna Marseglia, from the Karolinska Institute, points out, “ Keeping your blood vessels healthy is crucial to protecting your brain« .

Artificial intelligence to assess brain age

The team used an AI deep learning model to assess brain age from MRI scans. The information from the blood samples was then cross-referenced with the brain ages assessed, as well as data collected by the researchers on various lifestyle factors, medical conditions and cognitive tests.

What do we think?

The study of these factors of brain aging opens up new perspectives for combating neurodegenerative diseases such as dementia. By better understanding the mechanisms that help keep our brain “young,” we can adopt lifestyle habits that promote better brain health. It is essential to continue this research, particularly taking into account variations between men and women, to offer everyone the keys to healthy brain aging.
