Treatment of Intractable Anorexia Nervosa with Inactivation of the Nucleus Accumbens Using Stereotactic Surgery

Abstract: Background: For 30% of anorexia nervosa (AN) patients, conventional treatments are unsuccessful; this is termed intractable AN. Objectives: This study investigates whether ablation of the nucleus accumbens (NAc) using stereotactic surgery can arouse the physiological drive to eat in intractable AN patients. Methods: Eight patients with intractable AN were included: 6 patients underwent bilateral stereotactic radio frequency ablation in the NAc and 2 patients received bilateral NAc deep brain stimulation (DBS).… Show more

“…The 2 patients had baseline body mass indexes (BMIs) of 13.3 and 12.9, and at 1-year follow-up their BMIs were increased to 18 in one and 20.8 in the other. 292 These 2 patients also had normalization of core temperature and heart rate, and decreased anxiety and depressive symptoms. A slightly larger study from China on stimulation in the NAcc focused on DBS in the NAcc in 4 female patients, who experienced an increase in average BMI from 11.9 to 19.6 in a multiyear follow-up.…”

“…Son estos casos, llamados resistentes, cuya sintomatología incapacitante no disminuye con el uso de tratamientos médicos tradicionales, ni con diferentes enfoques psicoterapéuticos e incluso con terapias físicas como la electroconvulsiva o la estimulación magnética transcraneal, los que se convierten en crónicos con el paso de los años (Wang, Chang, Geng, Wang & Gao, 2013;Luigjes, et al, 2013). Para que la patología psiquiátrica se considere como resistente se destacan diversos aspectos a tener en cuenta durante el proceso de evaluación, los cuales se refieren a la pobre o nula o respuesta clínica a todas las tentativas terapéuticas en sus diferentes modalidades y periodos de aplicación, a pesar de que éstas hayan sido bien llevadas.…”

“…Para el caso de TCAR, Wang et al (2013) reportaron las evaluaciones pre y postratamiento, a través de estimulación cerebral profunda (ECP) del núcleo accumbens (NAcc) y ablación de NAcc, de ocho pacientes con anorexia, donde los hallazgos sugieren que la operación mejoró la conducta alimentaria de las pacientes con AN, lo que a su vez mejoró su condición física. Así mismo, los resultados indicaron que los síntomas de TOC, depresión y ansiedad disminuyeron después de la operación y que el nivel cognitivo preoperatorio mostró mejoría.…”
