Does everyone have aura before epileptic seizures?

No: Not everyone has an aura before a seizure.

Not the case.: For the most part, auras are a type of seizure. They represent a type of partial seizure; a seizure that comes from one area of the brain. People with primary generalized seizures usually don't have auras.

No.: Auras aren't characteristic of all seizure types and even with the types that are, not everyone has them.
