Summary

This study tests whether a gentle electrical stimulation device worn on the ear can help improve social, communication, and behavioral symptoms in adults with high-functioning autism. Participants use the device at home for 30 minutes a day, up to 5 times a week, for 3 weeks. The trial compares two different stimulation frequencies to see which works better.

Active substance

What this could lead to
If it works, this could offer a non-drug, at-home option to help manage core autism symptoms in adults.
What could go wrong
This is a small, early-stage trial with only 40 participants, so results may not apply widely. The treatment is also time-intensive (daily sessions for 3 weeks).
