Efficacy of Non-invasive Vagus Nerve Stimulation for Treatment of Low Weight Eating Disorders
Icahn School of Medicine at Mount Sinai
Summary
This project includes a 4-week randomized trial comparing pre-meal vagal nerve stimulation (taVNS) to pre-meal sham stimulation. The aims will assess if taVNS results in greater satisfaction, greater calorie consumption, less self-reported fullness, decrease in eating disorder symptoms, and less anxiety than sham stimulation.
Description
The purpose of this research study is to determine the safety and ability of a device that will stimulate the vagus nerve (taVNS), in 30 adolescents ages 14-17. This project will explore if stimulation has any effect on eating behaviors in individuals with eating disorders, such as Anorexia Nervosa. Study measurements include eating behavior and other measures of behavior. These measurements will take place before and in response to the nerve stimulation during the course of a 4-week randomized trial. Participants are assigned to one of two conditions: 1) Vagal Nerve Stimulation (n=20; this g…
