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
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 This study
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 Results may not be published yet.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 tested whether rhythmic light therapy can improve brain activity and memory in 20 people with mild cognitive impairment. Participants sat through three one-hour sessions with different light patterns while their brain waves were recorded. The goal was to see if certain light flickers increase brain synchrony and working memory.

What this could mean

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

Active substance
Flickering light device
What this could lead to
If it works, this could point toward a non-drug way to improve memory in people with mild cognitive impairment.
What could go wrong
This is a very small, early study with only 20 people. It only measured short-term brain changes, not long-term benefits. The light therapy may not help everyone.

Finished

Mar 2026

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.

Who can take part

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

Ages

55 to 80 years
