Eating disorders are extremely complex diseases. Our understanding of what causes them has evolved greatly over the years.
Originally, it was thought that such diseases were directly or indirectly inspired by influences of the American media, culture and families. Only recently have we discovered the important role that the brain plays in the development of food-related disorders.
Much study has been dedicated to the role of brain chemicals, but perhaps even more fascinating is the research conducted in the area of brain stimulation, especially on those individuals who have been entrenched in the disease for a long time.
Recently, 20 patients with severe anorexia or bulimia received targeted, non-invasive magnetic brain stimulation through a procedure called “repetitive transcranial magnetic stimulation (RTMS).” The stimulation was directed toward the region of the brain involved with control of thoughts, emotions and behavior. It is this part of the brain, the frontal lobes, that is essentially “off line” in people with active eating disorders.
The result of this directed brain stimulation was a 50 percent drop in binge eating and purging behaviors by nearly half the patients; another third saw their problems decrease by at least 80 percent. In some cases the behaviors went away altogether.
Healing this part of the brain and connecting it to other areas of the brain may prove to be the biggest benefit of this treatment modality.
About 8 million North Americans currently suffer from chronic eating disorders such as bulimia and anorexia. Although such research is considered preliminary, it is hoped that this approach will eventually provide an answer for many who still desperately want and need recovery.
