Abnormalities Found in 'Insight' Areas of the Brain in Anorexia

Bookmark and Share

In this study, researchers from the University of Illinois at Chicago and UCLA found that participants with anorexia nervosa scored lower on a test used to measure their ability to form insight and had more connective abnormalities in specific brain regions that are linked to error detection, conflict monitoring and self-reflection. This may explain why those with this diagnosis have trouble recognizing their dangerous and dysfunctional eating habits. “The brains of people with anorexia nervosa who have poor insight may not generate an ‘error message’ when told, for example, that they are putting themselves at serious risk for death by severe restricting,” said Dr. Alex Leow, associate professor of psychiatry and bioengineering in the UIC College of Medicine and corresponding author on the paper.
