In a pioneering new procedure, deep brain stimulation is being trialed as a treatment for the eating disorder anorexia nervosa. Neurosurgeons at the John Radcliffe Hospital in Oxford implanted electrodes into the nucleus accumbens of a woman suffering with anorexia to stimulate the part of the brain involved in finding food rewarding. Whilst reports emphasize that this treatment is ‘highly experimental’ and would ‘only be for those who have failed all other treatments for anorexia’, there appeared to be tentative optimism surrounding the potential efficacy of the procedure: the woman who had undergone the surgery was reportedly ‘doing well’ and had shown ‘a response to the treatment’.
It goes without saying that successful treatments for otherwise intractable conditions are a good thing and are to be welcomed. Indeed, a woman who had undergone similar treatment at a hospital in Canada is quoted as saying ‘it has turned my life around. I am now at a healthy weight.’ However, the invasive nature of the procedure and the complexity of the psychological, biological and social dimensions of anorexia should prompt us to carefully consider the ethical issues involved in offering, encouraging and performing such interventions. We here outline relevant considerations pertaining to obtaining valid consent from patients, and underscore the cautious approach that should be taken when directly modifying food-related desires in a complex disorder involving interrelated social, psychological and biological factors.
Acquiring valid informed consent from competent adult patients is a prerequisite for performing any type of medical intervention on them.
