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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study explores whether time-restricted eating—fasting for 14 hours each day—can improve blood vessel function in the brain and enhance cognitive performance in older adults. Participants will follow this eating pattern while researchers measure brain blood flow responses and retinal vessel dilation. The goal is to see if this dietary approach might support healthier brain aging.

What this could mean

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

Active substance
Time-restricted eating (14:10 daily fasting regimen)
What this could lead to
If successful, this could point toward a simple dietary approach to support brain health and cognitive function in aging.
What could go wrong
This is a small, early-stage study, so results may not apply broadly. The dietary change may be hard to sustain, and benefits are not guaranteed.
