STANFORD, Calif.--(BUSINESS WIRE)--Severe stress can damage a child’s brain, say researchers at the Stanford University School of Medicine and Lucile Packard Children’s Hospital. The researchers found that children with post-traumatic stress disorder and high levels of the stress hormone cortisol were likely to experience a decrease in the size of the hippocampus — a brain structure important in memory processing and emotion.
Although similar effects have been seen in animal studies, this is the first time the findings have been replicated in children. The researchers focused on kids in extreme situations to better understand how stress affects brain development.
