Background:

Anorexia nervosa (AN) is a severe psychiatric disorder with high relapse rates.
Traditional treatments have limited success for refractory and life-threatening cases.
Deep-brain stimulation (DBS) is emerging as a potential therapeutic option.

Observation:

A Shanghai group reported a 65% average weight increase in four AN patients post-DBS.
Patients achieved >85% of expected body weight, no longer meeting AN diagnostic criteria.
Leuven group studies support DBS for AN, detailing patient selection and target strategies.

Findings:

Preliminary results indicate DBS can facilitate weight restoration in severe, refractory AN.
The procedure led to significant weight gain and improved diagnostic status in treated patients.
DBS appears to be a promising investigational therapy for anorexia nervosa.

Implications:

DBS may offer a new treatment avenue for severe and life-threatening anorexia nervosa.
Further research is crucial to establish long-term efficacy and safety.
This therapy is investigational and not yet a standard clinical treatment.
