Study Summary

This trial will study whether electrical stimulation of the dorsolateral prefrontal cortex, which is important in determining the feeling of fullness after eating, affects how much food a person eats and weight loss over 4 weeks. It will also compare weight changes in people who attend weight loss counseling sessions and those who do not over this period of time.

Who is the study for?
This trial is for non-diabetic, right-handed adults aged 18-60 living in Phoenix, AZ with obesity (BMI ≥ 25 kg/m² and weight <350 lbs). Participants should have had a stable weight for the last three months. Exclusions include postmenopausal women, those with conditions affecting appetite or metabolism, recent medication use that affects metabolism/appetite, substance abuse issues, unstable medical conditions, contraindications for MRI scans or any other condition deemed unsafe by the investigator.Check my eligibility
What is being tested?
The study tests if brain stimulation of the dorsolateral prefrontal cortex influences food intake and assists in weight loss over four weeks. It involves initial inpatient testing followed by outpatient visits where participants receive either real transcranial direct current stimulation (TDCS) or sham treatment while maintaining a reduced-calorie diet.See study design
What are the potential side effects?
Possible side effects from TDCS may include tingling under electrodes during the procedure. There are no significant side effects expected from sham treatment. The long-term impact on brain function due to repeated sessions of TDCS is not fully known.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is this research initiative open to participants below the age of eighty?

"This medical experiment seeks participants who are of legal age (18 or older) and below the age of 60."

Answered by AI

What is the cap on enrollment for this clinical trial?

"Affirmative. According to clinicaltrials.gov, this scientific experiment is currently enrolling participants and was first posted on January 19th 2009. A total of 148 patients need to be recruited from 2 sites for the trial's completion; its most recent update was last November 19th 2022."

Answered by AI

Are there currently any opportunities to join this clinical trial?

"Affirmative. According to the information housed on clinicaltrials.gov, this medical trial went online in January 2009 and has been actively seeking participants since then; it most recently underwent an update on November 19th 2022. The researchers are currently recruiting 148 individuals from two distinct sites for the study."

Answered by AI

What are the key goals of this clinical evaluation?

"The primary measurement of this trial over a Baseline, week 9 period is to assess the fMRI activation in the left DLPFC when prompted with food and non-food visual cues. Secondary outcomes include responses to Perceived Stress Scale, Gormally Binge eating Questionnaire and MacArthur Scale of Subjective Social Status - each measured as percent signal change in the same area of brain activity when shown food versus non-food visual prompts alongside performance on relevant questionnaires."

Answered by AI

Can I be considered for participation in this clinical research?

"To qualify for this experiment, hopefuls must have prior exposure to electric stimulation therapy and be within the age ranges of 18-60. An estimated 148 patients are being accepted into the trial."

Answered by AI

Is Transcranial Direct Current Stimulation (TDCS) a risk-free procedure?

"As this is a Phase 2 trial, with some evidence of safety but none for efficacy, our team at Power gave Transcranial Direct Current Stimulation (TDCS) a score of 2."
