What's the relationship between blood pressure and seizures?

Sudden change: When global or regional cerebral perfussion pressure drops below 60 mmhg, unconsciousness usually happens. Seizure threshold varies for different brains and may be multifactorial but perfussion pressures below 60 will result in unconsciousness with or without seizures. A sudden drop in pressure may trigger seizures for some as well as electrolyte abnormalities even with pressures above 60or normal.
