NCT06804109

Brief Summary

The purpose of this study is to assess the effects of non-invasive vagus nerve stimulation (nNVS) on cognitive functioning in the users of e-cigarettes or vaping products. The investigators will use a digital wellness companion product (TRUVAGA™ device) that provides mild transcutaneous nVNS. The participants will be randomized to receive either a 2-min nNVS stimulation or control stimulation in the neck region followed by completion of three cognitive tests of attention and executive function.

Outcome Measures

Primary Outcomes (3)

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

    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.

    Immediately after intervention

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

    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.

    Immediately after intervention

  • Lexical Retrieval using the Verbal Fluency Task

    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.

    Before and immediately after the intervention.

Study Arms (2)

Active Stimulation

EXPERIMENTAL

Participants in the active arm will receive a 2-min transcutaneous vagus nerve stimulation using a portable hand-held digital wellness Truvaga Plus device by placing it on the anterolateral cervical area of the neck.

Device: Active nVNS

Control Stimulation

EXPERIMENTAL

Participants in the control arm will receive a 2-min transcutaneous stimulation using a portable hand-held digital wellness Truvaga Plus device by placing it on the posterolateral part of the neck (near the overlapping area between the trapezeus muscle and the shoulder).

Device: Control nVNS

Interventions

2-min transcutaneous nVNS stimulation using portable Truvaga Plus Device (electroCore Inc., Rockaway, NJ).

Active Stimulation

2-min control stimulation using portable Truvaga Plus Device (electroCore Inc., Rockaway, NJ).

Control Stimulation
