Non-invasive Vagus Nerve Stimulation (nVNS) and Cognition in Young Adult Vapers

This pilot study is looking at how non-invasive vagus nerve stimulation (nVNS) affects thinking skills in young adults who use e-cigarettes or vape. Researchers will use a device called Truvaga Plus to give either a real nVNS treatment or a control (inactive) stimulation to your neck for two minutes. Immediately after, you'll complete tests to measure your attention and processing speed. The study aims to see if stimulating the vagus nerve, which is involved in brain functions like attention, can help improve these skills in vapers. You can join if you are a healthy young adult between 18 and 25 years old and currently or previously used e-cigarettes. The study is currently unclear on its recruitment status and plans to enroll 100 participants.

Study design
This is a single-blind, randomized study with 100 participants, meaning you won't know if you're receiving the active or control stimulation.
What's involved
You will receive a 2-minute stimulation to your neck and then complete three cognitive tests immediately after the intervention.
Compensation
Not stated in the trial record.
Follow-up
Your cognitive abilities will be measured immediately after the intervention, with one test also measured before the intervention.

  • Efficiency of Attentional Networks using the Attention Network task (ANT)Immediately after intervention

    The Attentional Network Task (ANT) measures alerting, orienting, and executive attention that combines spatial cues with different flanker conditions. The efficiency of these three attentional networks is assessed by averaging reaction times and accuracy.

  • Attention and Processing Speed using the Symbol Digit Modalities Test (SDMT)Immediately after intervention

    The Symbol Digit Modalities Test (SDMT) is a sensitive and reliable neuropsychological test for the evaluation of speed of information processing, scanning and tracking aspects of attention, and working memory. SDMT is a simple substitution task that uses a reference key for the participants to pair specific numbers with given geometric figures. The test score is calculated based on the number of correct responses in 90 seconds.

  • Lexical Retrieval using the Verbal Fluency TaskBefore and immediately after the intervention.

    The Verbal Fluency Task is a neuropsychological measure of lexical retrieval efficiency and executive functioning. In this test, the participants are asked to name the words that starts with a specific alphabet (phonemic fluency) in 60 seconds. The verbal fluency score is calculated based on the number of correct/acceptable words produced within the allotted time.
