Concurrent Stroke and Seizure: Bidirectional Relationship and Emergency Response
Stroke and seizure can co-occur or trigger each other within seconds, as both disrupt cerebral electrical activity.
- Seizure: Paroxysmal abnormal neuronal discharge → altered consciousness, motor phenomena
- Stroke: Cerebral perfusion interruption (ischemic/hemorrhagic) → tissue injury, neurologic deficits
- Stroke→Seizure: Cortical irritation from infarction/hemorrhage
- Seizure→Stroke: Blood pressure surge or hypercoagulability from ictal activity
Simultaneous presentation demands immediate emergency evaluation and management.
