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 Results may not be published yet.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

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study explores whether playing gentle sounds during sleep can improve memory and alertness in people with focal epilepsy. Participants will have their sleep monitored at home and during two overnight lab visits, with cognitive tests before and after sleep. One night will include acoustic stimulation, while the other will not, to compare effects. The goal is to see if this simple, non-invasive approach can enhance sleep-related cognitive functions.

What this could mean

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

Active substance
Acoustic stimulation (playing gentle sounds during sleep)
What this could lead to
If gentle sounds during sleep improve memory and daytime alertness, this could point toward a simple, drug-free way to help people with focal epilepsy think more clearly.
What could go wrong
This is a small, early-stage study, so results may not apply to everyone. The sounds might not improve sleep or thinking, and the effects could vary widely between individuals.
