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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at how different parts of the brain handle mental effort in adults with epilepsy. Researchers will use tiny electrical pulses on the brain's surface while patients do thinking tasks. The goal is to create detailed maps of brain function to help guide future epilepsy surgery. About 30 patients already scheduled for brain monitoring will take part.

What this could mean

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

What this could lead to
If successful, this could improve understanding of how different brain areas control mental effort, potentially guiding future epilepsy surgery to avoid harming important functions.
What could go wrong
This is a small, early feasibility study with only 30 participants, focused on observation rather than treatment. Results may not apply to all epilepsy patients or lead directly to new therapies.

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 30 people

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

Started

Jun 2022

Expected to finish

Sep 2027

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.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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: * Male or female 18 years and older at screening. * Written informed consent is obtained from the participant to comply with the requirements of the study. * Stated willingness to comply with all study procedures and availability for the duration of the study * Currently undergoing clinically indicated intracranial EEG monitoring for planning of epilepsy surgery in the University of Minnesota/MINCEP program. Exclusion Criteria: * Pregnancy ruled out prior to approval for intracranial EG monitoring. * Persons who are rendered temporarily or permanently invulnerable by inability to understand the research due to study complexity, cognitive impairment, or by inability to make independent decisions owing to University of Minnesota or to Fairview health services.
