The study which measured brain age after about 10 months of lockdown showed that teen brains had aged at least three years in that time.
, was the first to compare scans of the physical structures of teenagers’ brains from before and after the pandemic started, and to document significant differences, said Ian Gotlib, lead author on the paper and a psychology professor at Stanford University.
Premature aging of children’s brains isn’t a positive development. Before the pandemic, it was observed in cases of chronic childhood stress, trauma, abuse and neglect. These To determine the average brain age of their samples, the researchers fed their brain scans into a machine-learning model for predicting brain age developed by the ENIGMA-Brain Age working group, a collaboration among scientists who pool their brain image data sets. They also evaluated mental health symptoms reported by the matched pairs. They found more severe symptoms of anxiety, depression and internalizing problems in the group that had experienced the pandemic.
Dan Siegel, clinical professor of psychiatry at the UCLA School of Medicine, noted that many individuals experience post-traumatic growth after a stressful experience. “The researchers need to be commended for the hard work to get that data,” Siegel said. “You want to ask the larger question, of how is the brain remodeling process being affected?”
