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

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 Results may not be published yet.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.

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 a new ultrasound method called Fast Cerebral Pulsatility Imaging (FCPI) to measure tiny brain movements in healthy adults aged 18 and older. Researchers aimed to see how these movements change from young adulthood to old age. The study involved 53 participants and used MRI scans for comparison. Results will help understand normal brain aging.

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