Ear-Zap therapy could calm brain inflammation after injury

This study is testing whether a mild electrical stimulation on the ear (called tAN) is safe and practical for patients in the ICU who have a traumatic brain injury. The researchers will check if the device can reduce inflammation in the blood and monitor changes in vital signs like blood pressure and brain pressure. About 42 adults with severe head injuries will take part, and nurses will also share their thoughts on using the device during daily care.
