Summary

This pilot study is testing a device that sends a mild electrical current to the brain (tACS) to see if it can reduce anxiety and improve sleep in people with generalized anxiety disorder and chronic insomnia. Thirty adults will receive 20 sessions over four weeks. The goal is to gather early evidence for a larger, more rigorous trial.
