Run by Hospital General de México Dr. Eduardo Liceaga · NCT07229924 · Data updated 2026-11-12
This study will test whether bariatric surgery combined with virtual‑reality Neurotracker sessions improves thinking and memory in adults with morbid obesity scheduled for surgery.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 18–65 with morbid obesity (BMI >40, or BMI >35 with obesity-related comorbidities) who meet bariatric surgery criteria and have no visual impairment or history of cerebrovascular events are ideal candidates.
✕Probably not a fit
Patients younger than 18 or older than 65, those with visual impairment, prior stroke/CVE, or active drug addiction are excluded and unlikely to benefit from the intervention.

What this trial studies
This prospective quasi-experimental study enrolls adults with morbid obesity who are candidates for bariatric surgery. Cognitive performance is measured using the Neurotracker virtual‑reality tool and the Neuropsi neuropsychological battery. Participants complete Neurotracker sessions three times per week for two weeks before surgery and repeat testing at postoperative follow-up visits, including at about 3 months. The study compares pre- and post-surgery cognitive performance to identify changes associated with surgical weight loss and reduced systemic inflammation.
Why it matters
Potential benefit: If successful, the approach could improve attention and memory after bariatric surgery and help identify patients who gain the most cognitive benefit.
How similar studies have gone: Prior studies have reported cognitive improvements after bariatric surgery and benefits from cognitive training in other groups, but combining VR Neurotracker training with Neuropsi testing in this population is relatively novel.
