epilepsy question.?

epilspsy is a condition that affects one out of ever 200 people in the united states. in a healthy person, brain cells produce small bursts of impulses in varying patterns. in a person with epilepsy , large numbers pf brain cells occasionally send rapid bursts of impulses simultaneousely, causing the person to have convulsions.

how would you explain these symptoms?
why do you think the symtoms go away after only a short period of time?

idk what symtoms they're talking about, its really confusing, please help?! THANKS!
