Is your brain aging faster than the rest of your body? An AI machine can now tell you

Human cognitive abilities decline with age. And neuroscientists have long known that this decline correlates with anatomical changes in the brain as well. So it's no surprise to learn that it is possible to spot the signs of aging in MRI images of the brain and even to determine a "brain age." The difference between brain age and chronological age can reveal the onset of conditions such as dementia. But the analysis is lengthy because the MRI data has to be heavily processed before it is suitable for automated aging.
