Brain test 2 level 148/25/2023 After one seizure, the chance of experiencing a second one is about 50%. Provoked seizures occur in about 3.5 per 10,000 people a year while unprovoked seizures occur in about 4.2 per 10,000 people a year. ![]() Up to 10% of people have had at least one epileptic seizure in their lifetime.
