Using an AI tool, researchers at Karolinska Institutet have analyzed brain images from 70-year-olds and estimated their brains’ biological age. They found that factors detrimental to vascular health, such as inflammation and high glucose levels, are associated with an older-looking brain, while healthy lifestyles were linked to brains with a younger appearance.
The results are presented in a paper titled “Biological brain age and resilience in cognitively unimpaired 70-year-old individuals” in Alzheimer’s & Dementia.
Every year, over 20,000 people in Sweden develop some form of dementia, with Alzheimer’s disease accounting for approximately two-thirds of cases. However, the speed at which the brain ages is affected by various risk and health factors.
