EEG changes after stroke and how they differ by brain injury location

Official title: Analysis of Electroencephalogram (EEG) Changes in Subacute Stroke Patients

Run by Bundang CHA Hospital · NCT07882082 · Data updated 2026-11-12

This study tests how EEG measurements change over time in adults who have had a stroke and whether these changes differ based on where the brain was injured.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 20 years and older who have had a recent stroke (ischemic or hemorrhagic) and can undergo EEG testing.

Probably not a fit

Patients whose stroke characteristics or medical stability prevent reliable EEG data collection may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study enrolling up to 200 adults with stroke. Participants will have an initial EEG assessment and up to four follow-up EEG sessions, with fNIRS measured alongside EEG. EEG data will be analyzed by lesion location and correlated with functional assessments and brain activity to explore associations over time.

Why it matters

Potential benefit: If successful, the study could improve understanding of how brain signals relate to recovery after stroke and help tailor rehabilitation strategies.

How similar studies have gone: Other studies have used serial EEG and imaging to relate brain signals to recovery after stroke, supporting feasibility of this approach.
