The market's steady expansion is attributed to growing awareness about neurological disorders, advancements in non-invasive neuromodulation technologies, and the increasing preference for device-based therapies over traditional pharmaceutical treatments.

A long-term market driver for the external VNS devices market is the rising global burden of neurological and psychiatric disorders such as epilepsy, depression, anxiety, and Alzheimer's disease. According to leading neurological studies, over 50 million people worldwide suffer from epilepsy, while depression continues to affect nearly 280 million people globally. Conventional medications often cause side effects or fail to offer lasting relief, leading to growing interest in alternative neuromodulation therapies. External VNS devices, being non-surgical and cost-effective, are increasingly recognized as a sustainable, long-term solution for chronic neurological conditions. Their ability to improve brain plasticity, stabilize mood, and reduce seizure frequency continues to drive their adoption across healthcare systems worldwide.

The COVID-19 pandemic accelerated the demand for remote and non-invasive therapeutic devices. During lockdowns, many patients with chronic neurological conditions faced restricted access to hospitals or surgeries. This boosted interest in external vagus nerve stimulation as a home-based therapy. Moreover, post-pandemic studies have revealed a surge in anxiety and depressive disorders, further increasing the need for safe, effective, and non-drug interventions like external VNS devices. The pandemic reshaped the healthcare landscape, pushing medical device manufacturers to innovate portable, wearable, and telehealth-integrated VNS solutions.

In the short term, a key market driver is the surge in government funding and research for neurostimulation therapies. Increasing clinical trials, favorable reimbursement frameworks, and FDA approvals for new devices are stimulating rapid adoption. Companies are focusing on miniaturized, user-friendly devices with smartphone connectivity, allowing doctors to remotely monitor treatment progress.

A major market opportunity lies in the integration of artificial intelligence (AI) and data analytics into VNS therapy systems. AI-powered feedback algorithms can optimize stimulation parameters for each patient, enhancing treatment efficacy while minimizing side effects. This personalized approach is expected to revolutionize the treatment of neurological disorders, opening new opportunities for medical device companies and investors.

A prominent trend shaping the market is the expansion of VNS therapy into non-traditional applications such as migraine relief, anxiety management, and inflammation control. Researchers are increasingly exploring the role of vagus nerve modulation in regulating immune response and stress pathways, which could position VNS devices as multifunctional wellness solutions. Moreover, the rise of portable, wearable external stimulators that can be self-administered is transforming patient compliance and accessibility in both clinical and home-care settings.

Global External VNS Devices Market Segmentation
By Application: Depression, Epilepsy, Others

The depression segment dominated the market in 2024, driven by rising cases of treatment-resistant depression and the growing awareness of nerve stimulation therapies as effective, drug-free alternatives. The epilepsy segment is also expanding steadily due to advancements in device precision and the increasing preference for external, non-surgical solutions to manage seizure frequency and intensity.
By End User: Hospitals, Ambulatory Surgical Centers, Others

Hospitals remain the largest end-user segment, as they serve as primary centers for neurological treatment and device-based therapy administration. Ambulatory surgical centers are expected to witness significant growth during 2025-2030, owing to their ability to offer efficient, cost-effective procedures and faster patient recovery. Furthermore, research institutes and private clinics are investing heavily in exploring new applications of VNS therapy, further driving adoption.
By Region:

North America held the largest market share in 2024 and is projected to maintain its dominance through 2030. This can be attributed to advanced healthcare infrastructure, high awareness of neuromodulation therapies, and the presence of key players like electroCore, Inc., and LivaNova PLC. Europe follows closely due to robust research funding and patient-centric healthcare reforms. The Asia-Pacific region is expected to grow at the fastest rate during the forecast period, fueled by the expanding patient base in China, Japan, and India, coupled with government initiatives supporting medical innovation and technology adoption.

Latest Trends and Developments
• Integration of Wearable and Wireless Technologies:
Modern VNS devices are evolving from clinic-based stimulators to wearable, wireless solutions that patients can operate independently. Compact, battery-efficient designs now allow for daily home-based therapy, improving treatment adherence and reducing hospital visits. This trend is particularly beneficial for elderly and chronic patients who require consistent therapy management.

• AI-Enhanced Personalization of Therapy:
Manufacturers are integrating AI and smart sensors into VNS systems to track physiological signals such as heart rate and stress response. The device automatically adjusts stimulation intensity based on the patient's real-time condition, ensuring maximum therapeutic benefit. This intelligent, data-driven customization is transforming the precision and success rates of neuromodulation therapies.

• Expansion Beyond Neurology into Holistic Health:
Recent research shows that vagus nerve stimulation can influence immune function, metabolism, and inflammation regulation. As a result, VNS devices are being tested for chronic pain management, autoimmune disorders, and even weight control. This expanding application base is positioning VNS as a next-generation solution for both neurological and systemic health challenges.
