What this trial studies

This study tests the effects of transcutaneous auricular neurostimulation (tAN) on cognitive performance in healthy adults experiencing acute stress. It is a randomized, double-blind, sham-controlled trial involving sixty participants who will be divided into four groups to receive either active or sham tAN treatment before or during a stress test. Participants will perform cognitive tasks before and after the intervention while biosensors collect biomarker data. The aim is to determine if tAN can prevent performance degradation due to stress.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 41 who can perform cognitive tasks and understand English.

Not a fit: Patients with significant medical or psychiatric conditions, or those currently using anti-anxiety medications, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance cognitive resilience in stressful situations for patients.

How similar studies have performed: While the specific application of tAN in this context is novel, similar neurostimulation approaches have shown promise in other studies.
