AI estimates brain age for dementia risk
A study published in the journal "Neurology" uses artificial intelligence to estimate brain age from MRI scans, aiming to identify individuals at greater risk of developing dementia in the future. The results showed that each year a person's brain appears older than their actual age increases the risk of dementia by 6%. This indicator remains independent of traditional assessment measures, with an associated 4% increase for each additional year. This approach helps with early detection of at-risk individuals, enabling earlier intervention and the tailoring of preventive strategies. The method for estimating brain age is more sensitive than conventional assessments, especially in people in the pre-symptomatic stages, contributing to better predictions regarding the progression to dementia.
