Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Approximately 20% of anorexia nervosa cases do not respond to conventional management strategies: cognitive behavioral therapy, weight gain contract, drug treatments, etc ... - whether they are applied outpatients or during very long hospitalizations. These situations of chronic evolution are characterized by a high rate of mortality. Brain stimulation could be an alternative therapy for these patients. tDCS (transcranial direct current stimulation) is a non-invasive stimulation technique that has demonstrated beneficial effects in other psychiatric conditions such as major depression or schizophrenia.

The objectives of the study will be to evaluate the efficacy of tDCS in anorexia nervosa resistant to conventional treatments on weight gain, eating behavior, psychological and nutritional behavioral scales, cognition, connectivity and brain activity.
