What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This trial tests whether increasing the brain's energy production can improve thinking and emotional control. Healthy adults aged 18 to 85 will receive either infrared light to the forehead, a coconut oil supplement, both, or sham versions of each. Researchers will measure changes in cognitive test scores and brain metabolism to see if these simple interventions can support mental sharpness.

What this could mean

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

Active substance
Infrared light delivered to the forehead via a headset, plus a dietary supplement of refined coconut oil
What this could lead to
If it works, this could point toward a drug-free way to boost brain energy and support clearer thinking and better emotional control in healthy people.
What could go wrong
This is an early-stage trial, and the effects may be small or not last. The light and supplement are unlikely to cause serious harm, but they may not improve cognition as hoped.

Lead sponsor

Other sponsor

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