Summary

This study tests whether a device that gently stimulates a nerve in the ear can help people recovering from a brain bleed. The device is placed on the left ear and delivers mild electrical pulses for 30 minutes, twice a day, for 10 days. Researchers will measure brain swelling and check for side effects in 186 participants.
