Brain waves may foretell stroke recovery
NCT ID NCT07741669
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This study is testing whether a simple, non-invasive brain wave recording (EEG) taken within days of a stroke can help predict how well a person will recover. Researchers will record the brain activity of 400 stroke patients and track their recovery over three to six months. The goal is to see if adding EEG information to standard assessments improves the accuracy of predicting long-term outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Resting-state EEG recording
- What this could lead to
- If successful, this could lead to a simple, non-invasive way to better predict stroke recovery and guide treatment decisions.
- What could go wrong
- This is an observational study, so it won't test a treatment. The results may not change clinical practice, and the predictive value of EEG might be limited.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population will consist of stroke patients treated at Xuanwu Hospital, Capital Medical University. Participants will be grouped according to their actual treatment pathway into a reperfusion therapy group and a non-reperfusion therapy group. The study team will record the type of reperfusion therapy, key treatment time points, and related information.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age \>=18 years, regardless of sex; * Meets diagnostic criteria for acute ischemic stroke, supported by cranial CT/MRI and/or vascular imaging; * Symptom onset time or last-known-well time is clear; * Clinical assessment indicates that resting-state EEG can be completed without delaying acute treatment; * Pre-stroke mRS \<=2, or basic independence in daily living before stroke; * The patient, legal guardian, or impartial witness provides informed consent to participate in this study. * The primary analysis population will be restricted to patients with mild-to-moderate to moderately severe acute ischemic stroke; an NIHSS score of 4-18 is recommended. Exclusion Criteria: * Primary diagnosis of hemorrhagic stroke, cerebral venous sinus thrombosis, brain tumor, encephalitis, severe traumatic brain injury, or other non-ischemic brain injury; * Pre-existing marked neurological disability, pre-stroke mRS \>2, severe prior dementia, or severe psychiatric disorder that would make follow-up functional or cognitive outcomes difficult to interpret; * Persistent deep sedation, coma, mechanical ventilation, severe metabolic disturbance, severe infection, or other conditions at the time of EEG acquisition that the investigator judges would markedly affect resting-state EEG background activity; * Status epilepticus or recent frequent clinical seizures around the time of EEG acquisition that the investigator judges would substantially affect interpretation of resting-state EEG; * Any other condition that the investigator judges unsuitable for participation in this study.
