What the study statuses mean

This study's is highlighted.

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 Results may not be published yet.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 combining a gentle brain stimulation technique called tDCS with computer-based cognitive training can improve thinking and memory in people still having symptoms 3 to 12 months after a mild concussion. Thirty adults will receive 10 sessions over about 3 weeks. Half will get real stimulation and half a sham (fake) version to see if the real treatment makes a difference.

What this could mean

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

Active substance
transcranial direct current stimulation (tDCS) device
What this could lead to
If it works, this could offer a non-drug way to improve thinking and memory for people with long-lasting concussion symptoms.
What could go wrong
This is a small, early-stage trial with only 30 participants. It tests a device and training, not a drug, so results may be modest or not apply to everyone.

Participants

About 30 people

The number the study aims to enrol. It can still change while the study runs.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.
