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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether Electrical Impedance Tomography (EIT) can produce accurate images of brain activity in people with epilepsy. EIT uses harmless electrical signals through electrodes on the scalp or brain to create images, and is compared to standard methods like MRI and EEG. The goal is to see if EIT can offer a fast, portable, and safe alternative for imaging seizures.

What this could mean

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

Active substance
Electrical Impedance Tomography (EIT) device
What this could lead to
If successful, EIT could become a fast, portable, and safe way to image brain activity during seizures, helping doctors better understand epilepsy.
What could go wrong
This is an early-stage study with only 42 participants, focused on accuracy rather than treatment. EIT currently has poor image resolution, so it may not outperform existing methods like MRI.
