Why anorexic patients cling to their eating disorder
Date:8/3/2009

Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior.

The research work of the Department of Psychosomatic and General Internal Medicine at Heidelberg University Hospital (Medical Director: Professor Dr. Wolfgang Herzog) arose in cooperation with the Heidelberg University Hospitals of General Psychiatry and Neurology. The results of the study were published in the prestigious American Journal of Psychiatry in June 2009.

Changes in brain activation associated with rigid behavior

Many young girls and women go on diets to achieve their ideal figure. Less than one percent of the population is affected by life-threatening anorexia. Despite intensive treatment, the course of the disorder is severe and chronic in 20 to 30 percent of the cases and about 10 percent of the patients die of the disease.

The Heidelberg researchers examined a total of 30 young women with and without anorexia by means of functional magnetic resonance imaging (MRI). The MRI device recorded the level of blood flow in various areas of the brain. Greater blood flow indicates higher metabolism and thus greater activity in this area of the brain.

The participants underwent a test that measured their capacity for flexible behavior modification of recently learned behavior. In this test, the subjects were shown a rapid sequence of various geometric shapes and asked to match them. After one test run, the matching principle was changed.

"In this study, we confirmed that anorexic patients cling to familiar behavioral responses more frequently than healthy subjects, thus suppressing alternative behavior," explained Dr. Hans-Christoph Friederich, head of the working g
