ClinConnect Summary

This clinical trial is looking at how vagal nerve stimulation (VNS) can affect patients with epilepsy, and whether it also has an impact on other body systems, including the immune system and gut health. VNS involves a small device being placed in the neck that sends electrical signals to the vagus nerve, which may help with controlling seizures. The main goal of the study is to understand how patients’ bowel habits and gut bacteria change before and after the VNS procedure.

To participate in this trial, you need to be getting VNS treatment for epilepsy for the first time and have seen a neurologist in the past year. Unfortunately, if you have had VNS before, are currently pregnant, or have certain medical conditions like a history of cancer or specific heart issues, you won't be eligible. If you join the study, you can expect to have some check-ups before and after the surgery to monitor changes in your health, including how your body responds to the treatment and any changes in your gut health. This trial aims to gather more information on how VNS might help not just with seizures, but also with other bodily functions.
