Interesting Brain Activity and Eating Disorder Studies
Tuesday, March 22nd, 2011
A recent study that was published in the American Journal of Psychiatry found results that discussed the idea of various the methods of therapy for eating disorders. It found that people who have different eating disorders may exhibit different brain activity patterns.
These different patterns actually related to aspects of a person’s eating disorder behaviors. A person seeking anorexia treatment showed that the person often shows anxious and inhibited behaviors. On the other hand, a person needing bulimia help was often determined to be more risk-seeing and impulsive. This also matches up with the compulsion nature of bingeing.
This study contained a sample of subjects with differing eating disorder diagnosis or no eating disorder diagnosis. The sample had 30 people with either anorexia or bulimia. This specific study didn’t test any people with other types of eating disorders. Then 16 people that didn’t need eating disorder help acted as a control group.
The actual study involved subjects pressing a button every time they saw a letter, except for the letter “x.” This required the subjects to show restraint by not pressing the button. While the subjects did this the researchers scanned their brain with an fMRI. They found that subjects with bulimia had to use more brain power in order to not press the button when they saw the letter “x.”
These findings lead the researchers to believe that eating disorder treatment methods should be changed. Since a person with anorexia proved to have more anxiety it may be beneficial to focus more on the anxiety during treatment. Then, for a person with bulimia it would be good to treat their impulsive tendencies to help them overcome the eating disorder. It’s a way of personalizing the treatment to help the person overcome an eating disorder.
The difficulty with changing anorexia or bulimia treatment based on a new study is the results aren’t enough. One study isn’t enough to completely change the approach of an eating disorder treatment program. Another study that studied brain activity showed some different results. However, the amount of subjects and the ages of the subjects were very different from the first study.
Avalon Hills supports all of the ongoing research in the field. The Academy of Eating Disorders and the National Eating Disorder Association are great resources for those that may have questions regarding eating disorder treatment and how research is developing in the field.
