Age is just a number, and doctors agree. A new AI-powered tool that uses MRI to assess ‘biological brain age’ appears to better reflect an individual’s cognitive state than the actual ‘brain age over time’. Proceedings of the National Academy of Sciences [1].

“People age at different rates and have different types of tissue in their bodies. I know this when I say Andrei IlimiaAssociate Professor at the USC Leonard Davis School of Gerontology and corresponding author of the study, news release From USC. “A 40-year-old brain may look as ‘young’ as a 30-year-old brain, or as ‘old’ as a 60-year-old brain.”

If MRI shows a large gap between biological brain age and chronological age, the patient is more likely to have a disease such as Alzheimer’s disease compared to a corresponding patient whose “brain age” closely reflects chronological age. You may be at increased risk for neurodegenerative disease.

This association is not surprising, but researchers and clinicians have long struggled to identify specific brain anatomy biomarkers that correlate with aging and cognitive decline in MRI scans. That’s where his AI capabilities come in.

Our research harnesses the power of deep learning to identify areas of the brain that are aging, reflecting cognitive decline that can lead to Alzheimer’s disease,” said Irimia. . Say.
