MedicalResearch.com: What is the background for this study?  What are the main findings?

Response: Bulimia nervosa is an eating disorder characterised by repeated episodes of binge-eating and inappropriate compensatory behaviours. It is associated with multiple medical complications and with an increased risk of mortality. Although existing treatments for bulimia are effective for many patients, a sizeable proportion remain symptomatic following therapy and some do not respond at all.

Evidence shows that bulimia is underpinned by functional alterations in certain brain pathways, including those that underlie self-control processes. Neuroscience-based techniques with the ability to normalise these pathways may therefore hold promise as treatments for the disorder.

One such technique is called transcranial direct current stimulation (tDCS) – a form of non-invasive brain stimulation that delivers weak electrical currents to the brain through two electrodes placed on the head. It is safe and painless, and the most common side effect is a slight itching or tingling on the scalp.
