Following a first<unk> , the risk of more<unk> s in the next two years is 40–50%. The greatest predictors of more<unk> s are problems either on the electroencephalogram or on imaging of the brain. In adults, after 6 months of being<unk> -free after a first<unk> , the risk of a subsequent<unk>  in the next year is less than 20% regardless of treatment. Up to 7% of<unk> s that present to the emergency department (ER) are in status epilepticus. In those with a status epilepticus, mortality is between 10% and 40%. Those who have a<unk>  that is provoked (occurring close in time to an acute brain event or toxic exposure) have a low risk of re-occurrence, but have a higher risk of death compared to those with epilepsy.
