A seizure is basically a synchronized firing of neurons as opposed to the more common unsynchronized firing taking place during normal neural activities. However, I am uncertain if the exact technical definition of a seizure restricts this synchronized nerve activity to the brain only .
I wonder whether a wave of synchronized firing can propagate up to or occur in the area of brain controlling the blood pressure level and hence affect the blood pressure of the individual going through a seizure? Or can the impact of a seizure propagate to other areas and hence affect other functions like cardio-vascular system and hence the blood pressure? Or can neurons connected to heart, but not necessarily present in brain, exhibit synchronization as in a seizure and thereby affect the blood pressure of an individual undergoing seizure?
Summarizing my question is: can seizures affect blood pressure?
