Brain Stimulation for Obesity
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.

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."
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."
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."
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."
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."
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."
