Using EEG in stroke units to find hidden seizures and predict epilepsy
Official title: The Value of EEG in Stroke Units
Run by Attikon Hospital · NCT07190976 · Data updated 2026-11-12
This project uses routine EEG in adults hospitalized with recent ischemic or hemorrhagic stroke to see if EEG can detect hidden seizures and predict who will develop epilepsy.

Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with a confirmed acute ischemic or hemorrhagic stroke who are hospitalized in the participating stroke unit within the first days after the event are ideal candidates.
✕Probably not a fit
People who are not hospitalized in the participating stroke unit, who present too late after their stroke, or who do not have a confirmed stroke are unlikely to benefit from this study's procedures or findings.

What this trial studies
This is an observational study enrolling adults admitted to a stroke unit after acute ischemic or hemorrhagic stroke. Participants receive routine EEG recordings within the first days after their event regardless of whether seizures are clinically suspected. Investigators will look for subclinical electroencephalographic seizures and EEG patterns that might be associated with later development of epilepsy, and will relate EEG findings to functional outcomes. The study is conducted at the Attikon University Hospital stroke unit in Athens.
Why it matters
Potential benefit: If successful, routine early EEG could allow earlier identification of hidden seizures and patients at higher risk of developing epilepsy, enabling closer monitoring or earlier intervention to improve outcomes.
How similar studies have gone: Previous research has shown that EEG can detect post-stroke seizures and that some EEG features correlate with later epilepsy risk, but results have been mixed and prospective data remain limited.

Show full inclusion / exclusion criteria
Inclusion Criteria: Patients over 18 years of age with confirmed acute ischemic or hemorrhagic stroke are eligible for inclusion in the study. Patients whose clinical presentation mimics that of a stroke will be included until the diagnosis of stroke is ruled out, at which point they will be excluded from the study. \- Exclusion Criteria: \-
