Role of EEG in Differentiation Between Ischemic and Hemorrhagic Stroke

ClinConnect Summary

This clinical trial is exploring how electrical activity in the brain, measured by a test called EEG, can help doctors tell the difference between two types of strokes: ischemic (caused by a blockage in a blood vessel) and hemorrhagic (caused by bleeding in the brain). The researchers want to see if the EEG results can also give clues about how well patients might recover after a stroke.

To participate in this study, you need to be between 18 and 80 years old and have had a stroke within the last 72 hours. This includes those who have had their first ischemic stroke or a hemorrhagic stroke confirmed by imaging tests. If you decide to join, you will undergo an EEG, which is a safe and painless procedure that records your brain's electrical activity. The trial is currently looking for participants, and it’s important to know that certain medical conditions or previous treatments may make you ineligible. Your involvement could help improve stroke care in the future!
