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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 150 patients who are unresponsive after a brain bleed (intracerebral hemorrhage). Researchers use EEG to detect hidden brain activity when patients are asked to imagine moving. The goal is to see if this activity can predict who will regain consciousness and how well they recover over six months. No new treatments are being tested—this is about improving predictions and understanding recovery.

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 help doctors better predict which patients will regain consciousness after a brain bleed and improve care decisions.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to direct improvements for patients, and results may not apply to all types of brain bleeds.

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

Inclusion Criteria: * 18 years or older. * Diagnosis of primary ICH (i.e., related to hypertension or anticoagulants) on Head CT and/or MRI in the frontal lobe, thalamus, or striatocapsular region. * Unresponsive to commands within 48 hours after onset of the bleed. * English, Spanish or, French as the primary language. Exclusion Criteria: * Major bleeding in the cortex outside of the frontal lobe, cerebellum, or brainstem (judged as a cause for unconsciousness as per the attending neurointensivist). * Other causes of ICH or different types of acute brain injury (e.g., traumatic brain injury). * Severe cardiorespiratory compromise and similar acutely life-threatening conditions at the time of enrollment. * Evidence of pre-morbid aphasia or deafness. * Unconscious prior to ICH. * Pregnancy. * Prisoners. * Health care proxy decides against study participation or decided for withdrawal of life sustaining therapies.
