Brief Summary

Deep brain stimulacion (DBS) clinical study in the subcallosal cingulate (CSG) and accumbens nucleus (NAc) for 8 patients with treatment-refractory, cronic and severe anorexia nervosa (AN) patients. The main objective is to show efficacy and safety. Studies show that SSG and NAc are strategical targets in the pathophysiology and the hypothetical surgical treatment in AN patients. The patients distribution (4 patients in each target) it will made by the AN type and the comorbidity associated, the reasons are: 1- It is well known the comorbidity treatment imoportance in the AN evolution, 2- The two differentes types of AN have differents clinical behaviour and prognosis, 3- Studies show efficacy in TOC and DM patients with NAc DBS and in DM patients with CSG DBS. The main variable is BMI. After a 6 months stabilization evaluation phase will be followed (only in patients that have increase 10% BMI) by a double-bind, crossover phase, where patients will receive 3 months with stimulation turned on and 3 month with turned off. All patients will have a 12 months follow up. The study secondary objectives are to know the relation btween the stimulacion answer (increase 10% BMI) and the differents variables, specially AN type, associated cormobidity, selected target and preoperative MRI tractography study.

Outcome Measures

Primary Outcomes (1)

  • Body mass index (BMI)

    BMI will be measured monthly from baseline till 12 months. Data will be compared with BMI in the beginning of the open label period

    From baseline till 12 months

Secondary Outcomes (2)

  • Adverse events during the study

    From baseline till 12 months

  • Psychiatric comorbidity

    From baseline till 12 months

Study Arms (2)

Deep brain stimulation ON

EXPERIMENTAL

Surgical procedure is necessary.In surgery, two cerebral electrodes (either in the Subgenual cingulate or in the Accumbens Nucleus) are connected to a subcutaneous generator at abdominal fat level, under general anesthesia. The patient will initiate the stimulation prior to discharge . At 6 months follow up, Deep brain stimulation continue 3 months more activated, patient and psychiatrist don´t know

Device: Deep brain stimulation ON

Deep brain stimulation OFF

Interventions

Infinity model of deep brain stimulation is placed ( 2 brain elecrodes and subcutaneus generator ) under general anhestesia. The system is activated
