Using brain stimulation to help patients prepare for weight loss surgery

Non-invasive Brain Stimulation to Prepare the Patient for Bariatric Surgery

Not applicable Interventional Masaryk University · NCT06874309

This study is testing if brain stimulation can help people with severe obesity better control their eating habits before weight loss surgery to improve their chances of success.

What this trial studies

This study aims to improve the long-term success of bariatric surgery for severe obesity by using non-invasive brain stimulation (tDCS) to enhance cognitive control over eating behaviors before the surgery. Participants will receive either active or sham tDCS stimulation at home, and their brain function will be monitored before and after the surgery to assess changes associated with weight loss. The study focuses on individuals with a high body mass index (BMI) and those who struggle with controlling their eating habits, which can impact surgical outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with severe or morbid obesity (BMI > 35 or 40) who exhibit disinhibition in their eating behaviors.

Not a fit: Patients with a history of heart disease, previous bariatric surgery, or those unable to comply with study procedures may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to better weight loss outcomes and improved eating behaviors after bariatric surgery.

How similar studies have performed: While the use of brain stimulation in obesity treatment is a relatively novel approach, preliminary studies have shown promise in enhancing cognitive control and improving outcomes in similar contexts.

Exclusion Criteria:

* Subjects unable to provide informed consent and those unable to understand and cooperate with study-related procedures (based on the physician's discretion)
* Subjects with a personal history of ischemic heart disease, myocardial infarction, stroke, heart failure, and atrial fibrillation
