Summary

This trial explores using a non-invasive intervention to treat anxiety disorders such as GAD, SAD, PTSD, and childhood separation anxiety. Participants are randomly assigned to receive a 25-minute 5 hz tACS or sham, with an optional extension phase.

Who is the study for?
This trial is for individuals aged 5 or older with anxiety disorders like GAD, SAD, PTSD, and separation anxiety. Participants must meet specific diagnostic criteria and be stable on any current medications or psychotherapy. They should have a caregiver if needed and no medical conditions that could interfere with the study.
What is being tested?
The trial tests transcranial alternating current stimulation (tACS) at 5 hz up to 2mA targeting the brain's amygdala over 12 sessions within a month. It aims to see if tACS can reduce anxiety symptoms compared to sham (placebo-like) treatment, followed by an optional phase where everyone receives tACS.
What are the potential side effects?
Potential side effects of tACS may include discomfort at the electrode sites, mild headaches, dizziness or nausea during or after treatment. These are usually temporary and resolve soon after each session.
