Summary

This study tests whether a gentle, non-invasive brain stimulation technique called transcranial alternating current stimulation (tACS) can improve sleep and reduce anxiety in adults over 60 who have chronic insomnia. Sixty participants will receive tACS sessions, and researchers will measure changes in sleep quality and anxiety levels using standard questionnaires. The goal is to find a safe, drug-free option for common age-related sleep and mood problems.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: transcranial alternating current stimulation (tACS)
What this could lead to: If it works, this could offer a drug-free way to improve sleep and reduce anxiety in older adults.
What could go wrong: This is a small, early-stage trial with only 60 participants. The treatment is non-invasive and generally safe, but results may not apply to everyone with sleep or anxiety disorders.
