Summary
This review explores transcutaneous vagus nerve stimulation (taVNS) for neurological and systemic conditions. It synthesizes mechanisms, parameter optimization, and challenges, offering a framework for clinical translation.
Area of Science:
- Neuroscience
- Medical Technology
- Systems Biology
Background:
- Transcutaneous vagus nerve stimulation (taVNS) is emerging as a therapeutic modality for various neurological and systemic conditions.
- Existing reviews often focus on clinical applications, with less emphasis on mechanistic synthesis and optimization strategies.
Purpose of the Study:
- To critically synthesize recent advances in taVNS, focusing on mechanistic pathways and optimization strategies.
- To provide a conceptually structured framework for understanding taVNS effects and guiding future research.
- To address methodological challenges and propose biomarker-driven approaches for personalized taVNS treatment.
Main Methods:
- Systematic review and critical synthesis of existing literature on taVNS.
- Analysis of neuroimaging, autonomic, and molecular data to elucidate taVNS mechanisms.
- Evaluation of research progress, methodological challenges, and translational gaps.
Main Results:
- Identified convergence and divergence in mechanistic pathways underlying taVNS effects.
- Highlighted methodological challenges in parameter optimization and personalization.
- Proposed biomarker-driven strategies for optimizing taVNS treatment efficacy.
Conclusions:
- taVNS holds significant therapeutic potential, but requires a deeper understanding of its mechanisms and optimized application.
- Integrating multi-modal mechanistic evidence is crucial for developing a testable model of taVNS action.
- Bridging the translational gap between research settings and clinical implementation is essential for widespread adoption.
