Vagus Nerve Stimulation in Children
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to study the safety and tolerability of transauricular vagus nerve stimulation (taVNS) in healthy children and to observe any changes in brain waves during treatment. Participants, already in the hospital for EEG monitoring, will receive a 30-minute session of taVNS. The trial focuses on children undergoing brain activity monitoring to understand certain spells or episodes. It excludes those with brain injuries, heart-related issues, or other specific medical conditions. As an unphased trial, this study offers participants the chance to contribute to groundbreaking research in pediatric neurology.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that transauricular vagus nerve stimulation is safe for children?
Research has shown that transauricular vagus nerve stimulation (taVNS) is generally safe for people. Studies have found it to be well-tolerated, especially compared to more invasive treatments. For children, this treatment is usually easy to handle.
Some mild and short-lasting side effects have been reported, but serious side effects are rare. The FDA has already approved vagus nerve stimulation for treating epilepsy in children, suggesting its safety. This background reassures that taVNS is designed to be safe, particularly because it is non-invasive and the stimulation is set to a level that cannot be felt.12345Why are researchers excited about this trial?
Researchers are excited about transauricular Vagus Nerve Stimulation (taVNS) because it offers a new, non-invasive way to potentially influence brain activity in children. Unlike traditional treatments that might involve medication or more invasive procedures, taVNS uses gentle electrical impulses delivered through the ear to stimulate the vagus nerve, which could help modulate neurological functions. This approach is particularly appealing because it aims to be a safe and comfortable option for children, with the stimulation adjusted to stay below the level of perception, meaning kids won’t even feel it. Additionally, the use of EEG monitoring allows researchers to observe real-time changes in brain activity, providing valuable insights into how this treatment could work.
What evidence suggests that transauricular vagus nerve stimulation is effective for brain wave modulation in children?
Research has shown that stimulating the vagus nerve through the ear (taVNS) may help treat certain health issues. One study found that using taVNS for several months reduced seizures in a small group of patients. Another study demonstrated that taVNS could improve sleep quality for people with insomnia and alleviate related symptoms. In this trial, children will receive one session of taVNS to assess its tolerability and effects on EEG readings. Regarding safety, taVNS is well-tolerated in children, making it a more appealing option than invasive treatments. Although more research is needed, these early findings suggest taVNS could be a helpful treatment for various conditions.46789

Are You a Good Fit for This Trial?
This trial is for healthy children who are undergoing clinical EEG at the investigator's institution to characterize spells. It excludes those with brain injury, heart issues like bradycardia or congenital heart disease, pregnancy, and those with a pacemaker or active cancer treatment.Inclusion Criteria

- Transauricular Vagus Nerve Stimulation
Trial Overview
The study tests transauricular vagus nerve stimulation (taVNS) in kids to see if it's safe and how their bodies respond. It looks at changes in brain waves during taVNS using an EEG while also monitoring heart rate and blood pressure.

Experimental Treatment
The investigators will enroll 10 children between 7-18 years of age who are admitted to the hospital for EEG monitoring for spell characterization to receive one session of 30 minutes of taVNS. The investigators will titrate taVNS to below perceptual threshold of stimulation and objectively assess tolerability. The following parameters will be used for taVNS: frequency 25 Hz, pulse width 250 µs, and varying intensities from 0.5 milliampere (mA) to 2 mA. Intensity will be titrated to be a level below perceptual threshold in a patient. The participant will have continuous cardiorespiratory monitoring via pulse oximetry and blood pressure every 5 minutes. EEG data will be compared before, during and after taVNS.
