New Study Sheds Light on Anorexia’s Lasting Impact

The study, led by Walter H. Kaye, M.D., director of the eating disorders research program at Western Psychiatric Institute and Clinic of the University of Pittsburgh Medical Centre (UPMC) and co-authored by Vijay K. Venkatraman, could lead to a better understanding of why some young women, who are typically worriers and perfectionists in childhood, are at greater risk of developing the disorder.
The study also shows that such patterns of temperament persist even after recovery.
“Functional magnetic resonance imaging (fMRI) of the brain is providing new clues to why people with anorexia nervosa are able to deny themselves food and other immediately rewarding pleasures,” said Kaye.
“In addition, we have a new understanding of why people with anorexia seem to worry so much,” he said.
In the study, the researchers studied 13 women who had recovered from anorexia, maintaining a normal weight and regular menstrual cycles for at least one year, and 13 healthy women in a control group.
Each participant was asked to guess whether a flashing question mark on a computer screen represented a number higher or lower than five. Correct guessers were rewarded with 2 dollars, while incorrect guessers forfeited 1dollar.
