Nurosym taVNS for Traumatic Brain Injury

(MINT Trial)

This trial tests a treatment called transcutaneous auricular vagus nerve stimulation (taVNS) to determine its safety and suitability for people with moderate to severe traumatic brain injuries (TBI). Participants will receive either the actual taVNS treatment or a sham version that appears identical. Researchers aim to ensure the treatment is safe and practical for hospital use. They also seek to assess its effects on inflammation, brain injury markers in the blood, and participants' recovery upon hospital discharge. This trial is ideal for individuals who have experienced a TBI within the last 24 hours and are expected to remain in the ICU for more than two days. As an unphased trial, it offers a unique opportunity to contribute to groundbreaking research that could enhance future TBI treatments.

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on immunomodulatory medication (drugs that affect the immune system).

Research has shown that transcutaneous auricular vagus nerve stimulation (taVNS) is generally safe for people. Earlier studies on taVNS in patients with severe brain injuries found it to be a safe and practical method, with no major side effects reported. Other studies on vagus nerve stimulation for conditions like migraines have also found it to be well-tolerated and safe, helping to reduce pain without causing significant problems. While more research is needed, current evidence suggests that taVNS is a safe option for those considering this treatment.¹²³⁴⁵

Most treatments for traumatic brain injury (TBI) focus on managing symptoms and preventing further damage, often using medications like diuretics, anti-seizure drugs, or coma-inducing agents. But Nurosym taVNS works differently, targeting the vagus nerve through transauricular stimulation. This method is thought to help reduce inflammation and improve brain function after a TBI. Researchers are excited because this non-invasive approach could offer a novel way to promote healing in the brain, potentially leading to better outcomes for patients without the need for traditional medications.

This trial will compare the effects of transauricular vagus nerve stimulation (taVNS) with a sham control in participants with traumatic brain injury (TBI). Studies have shown that stimulating the vagus nerve through the skin of the ear (taVNS) can aid brain injuries. This method has improved thinking skills and reduced anxiety in certain situations. Research suggests taVNS might also help regain muscle strength and protect the brain from further damage. Additionally, it has been used to lessen seizures by altering brain chemicals. Although no direct clinical evidence supports its effectiveness in consciousness recovery, these findings offer hopeful insights into its potential benefits for traumatic brain injury.¹³⁴⁶⁷
