AI Prediction Model for Brain Tissue Age Created

Mount Sinai researchers say they have employed AI, for the first time, to construct “HistoAge,” an algorithm that predicts age at death based on the cellular composition of human brain tissue specimens. It is said to have an average accuracy of 5.45 years. This sophisticated method can also detect neuroanatomical regions prone to age-related alterations,…

Effects of Quicker Biological Aging Show Up By Middle Age

For people whose bodies age more quickly than others, the cumulative effects show up as early as midlife, when signs of dementia and physical frailty begin to emerge, a study led by Duke researchers found. The results of the study1 suggests that identifying and treating the diseases of old age should begin by the time…

Subjective Age May Reflect Neurobiological Health

Using MRI brain scans, researchers have found that elderly people who feel younger than their age show fewer signs of brain aging, compared with those who feel their age or older than their age. The results suggest that elderly people who feel older than their age should consider caring for their brain health. We tend…

Cognitive Control: How Distraction Benefits The Aging Brain

Some people find it more difficult to focus on certain tasks as they get older. But even though distractions can be frustrating, they may not be as bad as you think. There may actually be some benefits to reduced focus, especially in people over 50, researchers at the University of Toronto and Harvard University suggest.…
