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.

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 Results may not be published yet.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

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 looks at people with drug-resistant focal epilepsy, a condition where seizures start in one part of the brain and don't respond to medication. Researchers will use advanced tests to better pinpoint the seizure source and guide treatment, which may include surgery or less invasive options like focused ultrasound or nerve stimulation. The goal is to improve patient selection and outcomes for these treatments.

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 how doctors select patients for epilepsy surgery or alternative treatments, leading to better seizure control and quality of life.
What could go wrong
This is an observational study that gathers data, not a direct test of a new treatment. It may not lead to immediate changes in care, and results depend on careful patient selection.
