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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study explores whether a non-invasive EEG-based technique can map cognitive networks in the brain before, during, and after tumor surgery. The goal is to help surgeons avoid damaging areas critical for memory and thinking. Ten adults with brain glioma will undergo neuropsychological tests and EEG recordings to see if this approach improves cognitive function preservation.

What this could mean

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

Active substance
EEG-based neural signal decoding procedure
What this could lead to
If successful, this approach could help surgeons avoid damaging cognitive networks during brain tumor removal, potentially preserving memory and thinking skills.
What could go wrong
This is a very small, early-stage study with only 10 participants, so results may not apply broadly. The EEG technique may not reliably identify critical brain areas in all patients.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 10 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Jul 2028

An estimate. End dates often move.

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.

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 years to 75 years. * Patients diagnosed with brain glioma and scheduled for surgical treatment. * Conscious and able to understand study procedures. * Able to complete neuropsychological assessments. * Willing to participate and provide written informed consent. Exclusion Criteria: * Severe dysfunction of major organs (heart, lung, liver, or kidney). * Severe psychiatric disorders or cognitive impairment. * Severe language impairment preventing completion of study procedures. * Any other condition judged by the investigator to make participation inappropriate.
