Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether high-intensity brain stimulation (HI-tACS) can help people with gambling disorder. Researchers will give 60 adults either real or fake stimulation to see if it reduces gambling urges and improves thinking. Participants are followed for three months to check lasting effects.

What this could mean

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

Active substance
High-intensity transcranial alternating current stimulation (HI-tACS)
What this could lead to
If it works, this could point toward a non-drug treatment for gambling disorder by improving brain function.
What could go wrong
This is an early study with only 60 people, so results may not apply widely. The stimulation may cause discomfort or not reduce gambling symptoms.

This is an AI summary of the original study and may miss details. Read our disclaimer.
