[Functional Neurosurgery for Anorexia Nervosa].

Anorexia nervosa (AN) is a serious psychiatric disorder characterized by disturbances in body- and self-perception and excessive weight loss. AN is sometimes refractory to conventional treatments such as medication and psychological therapy. Therefore, the neurosurgery for psychiatric disorders (NPD) has been studied. While the efficacy of NPD has previously been reported and is currently being studied, it is not performed in Japan. We introduce the results of representative studies that investigated functional neurosurgery for AN. (Received May 22, 2020; Accepted November 20, 2020; Published April 1, 2021).
