Deep Brain Stimulation for Severe Anorexia Nervosa

This week, a team of researchers from the University of Toronto published a paper in The Lancet describing the results of a small study using deep brain stimulation (DBS) to treat severe/chronic anorexia nervosa. Major news outlets, including the BBC, reported on the findings. A few people emailed and messaged me asking me to do a post about it (which is cool! I love it!). So here it is.

DBS is a surgical procedure that involves implanting an electrode that delivers electrical signals to the brain. DBS is used to treat Parkinson’s disease and other movement disorders with good success, and has recently been implicated in the treatment of OCD and depression as well. (This is a pretty good video explaining how DBS works for movement disorders. There’s lots of information online about how DBS works, so I won’t go into detail here.)

This is not the first time that DBS has been used to treat anorexia nervosa patients (and I actually remember hearing about this when I was in undergrad, a few years ago). There have been two …

Chronicity in Eating Disorders: How Do We Define It and What Do We Do About It?

It comes as no surprise that the earlier eating disordered individuals receive treatment, the higher the likelihood that they will make a full recovery. In other words, the duration of the illness is inversely proportional with the likelihood of full recovery.

The problem is that a lot of eating disorders are not caught early. That a lot of people don’t have access to the treatment they need. Insurance will not cover it, their doctors don’t think it is a problem or won’t treat it, or there is simply no space. And even if there is space, and insurance will  cover it, dropout rates are incredibly high and treatment success is meager. The end result? Sometimes it is a success story – a full or partial recovery. But other times, the stories make headlines across the world, and not for good reason.

So then, what can we do about the individuals who don’t recover within the first one or two years of getting sick?

Again, it comes as no surprise that this question has not been explored in …

How Can We Treat Chronic and Severe Anorexia Nervosa? (On the Need for New Approaches)

Treating anorexia nervosa is hard. Treating chronic and severe anorexia nervosa is a lot harder. Although the situation seems to be improving, there are really no evidence-based treatments for anorexia nervosa – particularly for those who have been sick for a long time.

The treatments that many often claim are evidence-based are often only applicable to a select subgroup of ED patients, and even then, the evidence is usually weak. (I’m referring to Maudsley/FBT (family-based therapy) for adolescents with <3 yrs duration of AN and CBT for bulimia nervosa.)  But what about those with long-standing anorexia nervosa? In a recent review, Phillipa Hay and colleagues set out to conduct a systematic review of randomized controlled trials of treatment for chronic AN.

Randomized controlled trials or RCTs are at the heart of evidence-based medicine:

Hay et al searched the literature to identify RCTs where, among other criteria, the mean duration of illness was at least three years. They found eleven studies, but they could only confirm that a majority had a mean duration of over 3 years in just four of …
